Found these on ebay: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160275165857&_trksid=p2759.l1259

I've been on the lookout for ages but trying to play it cool... Trying. :p

There's a while to go but I'm hoping for a bargain! Quick question: Will these fit mine without using spacers? They're off an 8 series originally so it looks like the offset is different.

Also, what's the score on changing the aspect ratio of the tyre size - example 235 - 50 - r17 on the front? Would that cause any negative effects?

You'll need spacers to fit E31 wheels to an E34... sadly

The rear ones by the look of it only need to be 3 mm, but the fronts may need 10mm spacers - if I've got my maths the correct way around.

That's the way I was looking at it - If the offset is less does that mean the wheels are more 'in' at the arches?

You say sadly, is this a bad thing? I assume it won't affect the running in a negative way. Oh, will normal bolts do the business?

I think you have it backwards. You might find a 10 offset on front that calls for 20, the wheels will stick out and could interfere with the wheelwell opening.
HERE (http://www.wheelsmaster.com/rt_specs.jsp?item=Wheel-Tire%20size%20comparer&showRim1=1&showTire1=1&sw1=225&ar1=60&bd1=15&rd1=15&rw1=7.0&et1=20&showRim2=1&showTire2=1&sw2=245&ar2=45&bd2=17&rd2=17&rw2=8.0&et2=25&text1=&text2=)
Adjust both for 235/45/17 with 17 x 8, then adjust the offsets to see the comparison.
You should note that on the 20 offset, the backspacing is 134 millimeters. The 10 offset is only 124 mm which means they will stick out farther.
I don't see the 10 mm being a huge issue, though. And in the staggered set, the rear offset is so close as to not be a problem, 19 for the e31 wheels vs 22 stock e34.

Hey thanks for that, it was useful and I think you're right looking at the diagram. I shouldn't imagine 10mm difference being noticible to the naked eye! Hopefully someone who's done the same swap before will chime in to confirm!

They are round the corner from me if you want me to take a look and speak to the guy to see if he will do a deal? I owe you one for those spigot rings....

Hey man that's mighty kind! That'd be great only if no trouble... I was hoping I was going to be lucky at the auction :) but can't hurt to aks him I suppose?!!!

Yes, they should fit just fine as the fronts will stick out 10mm more than a normal E34 rim. And that's worked fine for many others.

Stick with the 235/45 on the front & 255/40 on the rear.

Thanks - I was hoping you'd spot this thread - you have an 8 don't you?!

Thanks for the info - I'll do that. I'm eyeing up tyres already and I haven't even got them yet! :p

No 8 yet. Just my M-Sport right now. Will add an '01 740i Sport next after the M-Sport is paid off. Maybe by then an '01 740i Sport will have come down in price a good deal to a vaguely reasonable level. Then maybe an 8 after that.

Thought about an 8 before I bought the M-Sport as I'd been looking for the M-Sport for 2 years. But an 850CSi or 840Ci are still too pricey. Not to mention I don't really have the $ to keep the electrical system in an 8 up to spec and don't feel like being an auto sparky all of the time.

So I started looking for a nice 740i Sport. And couldn't find one that was the proper color & spec. Did find one that was about 3,700 miles away and felt that was too far to go for a car.

A couple of months later I found my M-Sport after searching for 2 1/2 years. Happened to be 3,750 miles away. Wasted no time in setting up financing & booking a plane ticket...:D

What is the offset on the wheels in your sig? They look "out there".
Bubba has the correct tire sizes as well, 235 and 255.

Oh, and only go with the 255/40's on the 9" wide rear rim. Should you happen to end up with a different set of T-Stars that are 8" on all 4 corners then keep it 235/45 all the way around.

I've had Michelin PS2's & PS A/S on my T-Stars, both worked great, but I liked the PS2's a little better. Have tried a couple of different Pirelli's on a friend's '93 M5 w/T-Stars and haven't liked them so much. The P-Zero Nero M/S were ok. But the Michelin's severely outclass the Pirelli's.

10 mm will be noticeable...i put some 8 and a halfs on,combined with 5 mm less offset they look much further out than 8 inch wide 20 mm offset..

You're absolutely right... The fronts are out there. Never really noticed till now but I guess the throwing stars won't be much different. I'm going to try to find the current offset now, but mine are replicas so we'll see what I can find!

I've emailed the guy to ask if I can see them tomorrow, I'll PM you, let me know of any specific questions you want me to ask.
