If you do not have a lift, you can not install them yourself) or modify the existing subframe to give TOE and Camber adjustment. At my existing ride height, with the kmac's set to 0, toe spec was ~1 degree POSITIVE and camber was just over 3.5 degrees. That spec if uncorrected means buying new tires every 3000 miles. Or a complete set every 6000 if you rotate front to rear.


There are better pics on DTMPower IIRC, and multiple vids of badmannersgod 's iT on youtube.

Really? Never heard about that before. I have a full suspension with weight in the trunk from the subwoofer and have had my Pilot Sports for almost 30k miles. No rotating, staggered and no bushing set. I have seen 5 other tourings lowered without them and their tires lasted the same length as a sedan.

how low are you over stock? probably not as low as I am and he wants to be. most tourings are only 1 to 1.5 inches, and the camber/toe change is almost exponential once you get past that.

BMA or dealer

I am about 1.25-1.5 lower front and rear. The tourings lower the same amount if using the appropriate springs. I also run front camber plates (total front negative camber ranges 2.25-2.5). I have also previously used Racing Dynamic springs which lowered the front even more. I have done more than a dozen aftermarket e34 suspension installations on e34s and everyone's tires lasted more than the 6k miles even with cappy tires. Perhaps there could be a problem with your e34 or the previous owner dented something. Perhaps the previous bushings were just worn out or the rubber life was shorter with your climate conditions. The e34s I see as well as have installed suspensions go through simiar weather as Canada with all 4 seasons.

Just wondering, you mention almost exponential, what formula are you using? What do you mean by that. I have done my own alignments on e34s and the rear toe does not change with the lowering.

yes toe does change. but since you are the suspension and tire 'guru' of b.i. I can't very well disagree with you can I? I might get banned for telling you you are wrong again.
Instead of simply reading that my experience is different than yours because I am LOWER than you have any experience with, you denigrate and cast aspersions.


I will suggest a test if you would like to know what i am talking about.

Set your e34 on the rack, put a jack under the diff and unbolt the struts. let it down and up while watching the numbers on the table, or just load weight in it while it is on the table until your rear opening is 23 inches above the ground.

Ride height: my rear wheel well opening was at 23.5 inches above the floor, with 1/4 tank of gas and no 3rd row, sub box, or luggage. that seems to be about an inch lower than most everyone elses sedan or touring.

Ok, so I'm pretty sure I'm going with Coil-Overs, it's a complete package with adjustible height for winter and going to be about 200 cheaper than Shocks, Springs, Plates, Pads, Camber Plates, etc, etc
