Rather than fully write my own... why not just rebadge some words? They still hold true ;)



First impressions:

The E39 is a fatter car, and feels like it. Steering is very good, but not as sharp as our E34s. Also, throttle response is better in our cars than the E39s (wire vs electronics?). This I was a little puzzled by, but no doubt, while the e34 feels like it's hardwired to your brain, the e39 seemed to take half a second to come around.


Driving hard:

The E39 540i is a monster. The torque is phenomenal. Flooring it in a straight line or a light sweeper is accompanied with a 'holy sh*t I can't believe how much_ass I'm hauling' kind of feeling.


Little things:

The e39 is 12 years newer, and has some stuff in it that I like better than the e34. Like the glass sunroof. Remote operation of windows. Heated steering wheel. Telescoping steering wheel. The Magnaflow exhaust and intake on the e34 sounds more badass than the e39 stock though. Lots of little stuff I'm discovering...


Final notes:

I think the e39 540i is just about the perfect car. It can do everything. If I had to own only one car for the rest of my life it would be that one BUT with a 6 speed. Plenty of gizmos to keep you from getting bored, and it's really two cars in one: grocery getter and fighter. That being said I am looking forward to getting home in the e39. I was worried that after a good bout in the e39 it would ruin the e34 for me and it just about did. The e34 still has the edge when I feel like going track crazy and tearing it up. The other problem is when you have a car that is that fast, it is frustrating when you want to use it but can't. The e39 540i in sport mode gets to 100kph in a heartbeat, and to car-impounding 150kph in a hair more... Like a hot babe that leads you on all night and then sends you home to clean your own pipes. It so thoroughly belittles everyday driving situations that you feel as though you're not getting your money's worth unless you're doing 2x the speed limit, which you can't really do all that much anyway.

I need to drive the e34 this weekend. All that's in there are two boxes of baking soda. Big storm is coming... who needs traction control? ;)

I think you might be paraphrasing a bit too much, 280 lbs of torque in a car that heavy isn't "phenonemal"...My last car had as much, at the same weight, and while it certainly wasn't slow, it wasn't M5 phenomenal, which is what is being described in the link you sent.

A humbling experience: Put your 280 torque up against a car with 400 or more on the highway and put the pedal to the floor from 100 km/h. If you have a fragile ego, never do this :p

But that said, I am glad that you like your car, that's the most important thing!

Lol... man, in sport mode, this thing pulled a helluva lot more than the 535... BUT !! It also squatted like hell so that contributed to the pull feeling. The springs are going in today so we'll see.

I'm sure it's a great car to drive but I can't get past the looks of the e39 personally, it just went backwards in terms of style and road presence. Your 535i looks amazing, really aggressive and I've never saw an e39 that could compare. All personal taste though and everyone likes different things, but for me e34 wins hands down.

In terms of the drive I took a friends 330i (2003) out the other day for a spin and there was a world of difference between that and my 535i. It was a much 'comfier' ride with all kinds of luxuries like heated electric seats, sat nav, traction control and even a TV... I was actually watching Jeremy Kyle while forging down a dual carriageway! The ride in terms of comfort was in a word, awesome. It was an auto (steptronic) and it was clearly very very fast, but I must say it didn't have the same 'raw' powerful feeling as the e34. I watched as the needle on the speedo climbed effortlessly (in sport mode!), but it didn't feel like I was going that fast and the torque figures are very similar to those in my 535i which I found strange. I'd feel confident at the lights with it in the 535i lets put it that way, even with the 13 year age gap.

I know this doesn't transfer exactly but you can see where I'm going with this. I would love to find out what happens if you pit the e34 against the e39!

A mate of mine had a 2002 530i Sport. Black with Terracotta leather, all boxes ticket... It was awesome!! Never gave it hell to see how it performed, but that quantum leap to a new, full-loaded interior was amazing.

I am a sucker for gadgets and well designed stuff... 5 positions on a simple E34 doorlock?? Awesome!! But all the Sat-Nav, courtesy/mood lighting, bluetooth connectivity etc of the E39 really, REALLY sat well with me!! I liked it a LOT!!

Now, if only I could get a late build E34 with all the naff gadgets of an E39... :boner:

I bought the e39 540 before the e34.

I definitely agree about all of your observations so in my quest I did find out several upgrades to increase the drive. First start with swaybars, rear then front, get the right wheels and tires. I replaced my terrible dunlops with Michelin PS2s. Then make sure all the suspension is good with the bushings and balljoints (just like the e34). The brakes can be better so stickier pads is a good idea. Good tune up with spark plugs, the MAF uses platinum as one of the components and wears out with general use. So, after years of use, there is a way to replace only the sensor part with a VW one. Good cheap replacement.

The power is adicting and the handling and braking can be great too. The e39 really shows how the development has evolved with the electronic technology and the aluminum suspension parts. The 324lb/ft of torque that came stock in my 540 doesn't hurt too. Engine software speeds up the TB a little and tranny software changes the shift points for sporty driving. Whats nice is these are unobtrusive upgrades.

Good luck and enjoy the new ride!

Suspension components are good. Put in H&R springs. All fluids done. Will do plugs soon. Just lowering it made a helluva difference. The squat and roll is now minimized.

You should only use H&Rs with some matched shocks. Any stock length shocks are too long for the H&Rs. You need Konis or Bilstein Sports. Why did you choose H&Rs? H&Rs are known to be firm and should not be used with stock non-sport shocks.

I really do not understand why people change the springs and not change the shocks. I mean, if someone is only looking into lowering the car for the look, then cut the springs. Tighter springs that are lowered will have less travel. Also the shock has to be tuned to work with the oscillations and frequency of the springs as well as work with the reduced amount of travel. Sport shocks are better tuned to match the spring oscillations. They do make a Sachs kit for the e39. Also, I would have gone with the swaybars first as even the stock non-sport suspension can work with this upgrade.

My e39 came with the sport package and I looked, drove, and installed different suspensions on e39s. With the handling, the e39 owners and I not only looked at off ramp turns, but quick turns with body-response to go back to normal or body-reaction. So if I have to make a quick left to go around an idiot in a car how well does the car react to the quick manuver and then how well if I have to follow with a quick right. I have a Jeep Grand Cherokee, 1993, and with large swaybars it handles amazingly, but I wouild not say it transfer weight left to right as quick as my e34. The suspension has to work together and just changing the springs can make the ride and handling worse in different situations. Squat and roll are only minor things in handling and ride. I would like to ask how it is when going over a bump, a drop such as a pot hole, uneven surfaces, return after a quick turn, braking and acceleration while going over bumps, uneven surface? Do the tires stay on the ground while going over irregularities?

Sorry not to take the thread over, but to realy ask questions and try to help you out before you spend money or spend more money because you have to do something over.

That amazing feeling is more likely because of the suspension design. The rear subframe is more solidly attached to the e39 body. The rear subframes with models such as the e34 are not as solidly mounted; in order to help isolate vibrations the rear subframe was given more play and less direct attachment to the body. I get the same feeling in the e39 and it is not because my car is squatting, it's because the power transmitting to the rear is not getting lost in the subframe play, instead it is helping apply more direct power to the whole car. The e39 does help manage the vibrations coming into the cabin by the use of aluminum, a larger stiffer subframe which is like a box in design, and has 4 big subframe bushings instead of 2.

H&R was chosen by Charlie @ Bimmersport... and if I can't trust him to be in the best interest ;) I believe they are non-sport. I'll have to check.

They are sport especially if they lowered the car. Yeah, Charlie seems like he wanted to sell you something or you did not tell him about using stock shocks. You have to be a smart consumer. Hmmm, worn underdamped shocks with stiffer springs. This kind of stuff isn't rocket science and is not any different than the e34 or any other vehicle. Do a search in about every forum and you will see people use lowering/sport prings with new sport shocks. Just plain makes sense. The basics about suspension tuning. The e39 doesn't change physics. Like every other BMW the e39 seems like it defies physics.

Usually I do... as I brought in the Konis for the e34... but in this case it should be good... though I'll question a bit. Still, he's not one to do something that will cause issues as noted.

What's the difference with the kind of job you've done or plan (shorter spring and stiffer shock) and the regular BMW sport suspension option ? Is it equivalent ? In general does peoples try to imitate the BMW sport suspension version (get the closer to it) or go further (even stiffer) ?

I would say, forget what you hope others do for you. See how your car handles and keep on observing. You were right with the e34 to get the shocks, again I don't understand why not now. It really goes against everything you learned just because someone else says it will work. Well, it will work, just how well and how well in the long run.

As far as sport package e39s, many only do subtle upgrades with the sport suspension, thats also if they choose to do a suspension upgrade. They may do swaybars. Some have tried to swap in Konis, but the factory sport suspension is about 1" (give or take) taller than what would work best for the konis. I have the sport suspension from the factory. The best upgrades were the swaybars. Then getting good tires. I opted for the sticky PS2s as well as using wider tires used on the M5. It is much more balanced with the 245s in the front. The ride is very nice, I mean very nice and compliant. I am also running 275s in the rear. Before the larger tires, I autocrossed the e39 and so the testing of before and after the swaybars were done.

One note, I am wondering how many people here have seen a long wheelbase car like the 5-series in an autocross or a track. I have seen some amazing drivers with the 5-series and the car would sway a little. It's not all about flat corning, it's more so about carving in the turn. Look at Sabine and you will see how much the e39 sways or weight shifts. For good balance of handling and ride, there needs to be a resonable amount of sway because of the long wheel base. It does help carve the turn. If the sway isn't there, then the front will push, or oversteer. Now to combat you can add camber plates and sway bars. So, the main point here is if the springs are too stiff and your corning is too flat, then the 5-series will not carve as well. Have you ever felt like a car has a place where it sits on a big turn and it just sticks?

Qube, I hope things go well for your supension. I simply go by the rule of if you stat from scratch, why not do it right. So, if you are doing your suspension, why not do it right. You know the suspension would have been complete if the springs and shocks were done well. So thats why I ask why did you not trust what you and everyone else knows. My only assumption could be that you wanted the look, or you did go cheap, or it was an impulse buy. Good luck and I hope it works out well for you.

Wow! Thanks for taking the time to write a story :)

In essence, it's an impulse buy. Was inexpensive and I jumped on it. In truth, I am going to leave them in until the stock struts wear, and then replace them with Konis as well. If I got the Konis at just over $100 for the set like I did for the e34, I would have done it immediately in a heartbeat. Will need to read into what to match to the H&Rs.

Swaybars? That's an interesting thought. I'll look into that. Thanks.

Sticky rubber and staggard wides are in the future. I'll run the Privat Kraftwerk first, then move into something more comfortable.

Will update. Thanks again for the good read!

No Problemo. Sometimes to do the right thing is to admit our obsession flaws, like impulse buying and going a cheaper route. The H&Rs are kind of stiff and from what you have described before in ther posts, it sounds like you want a compliant ride. The konis and H&Rs might be too firm for you. Using Eibach or Dinan springs with Koni shocks would give you the handling with good ride.

Keep us updated.
