Rear camber issue

[RCV7]

Here's an update with pictures as of March, 14th.
Just installed H&R sports & Bilstien sports. I’m also running SSR Comps 17X8+44 with 17X45X225 Hankook V12’s. The front looks fine but the rear camber looks a little too aggressive, I’m guessing it’s in the 2.5-3 range. I’ll be DD’n and some auto-X when the season starts. I must say, it corners very well but I’m also going to guess it’s going to eat up tires pretty fast as I do a lot of straight line driving and the toe is not good this low. I'm also not crazy about the dropped look in the rear. Looks very ricey, I'm not 21 years old anymore LOL! I do like the sleeper look though.
Should I install rear springs pads to raise slightly? Maybe swap out the rear springs? They are H&R sports. Thanks in advance

I have everything installed below.
From cooljess76: “Good call Dave, I didn't think about that. RCV7, if you're running the 2.8L Z3 medium case diff, the ti halfshafts will still be too long, you'll need to get 6cyl e30 halfshafts and output flanges, which will also require you to shim your ABS sensors(just a washer).
So to clarify, use your current 2.8L Z3 subframe(same as 318ti subframe), 318ti trailing arms, 2.8L Z3 medium case LSD , e30 325i or 325is halfshafts and output flanges, pick up two washers with 5/8" centers at your local hardware store and shim your ABS sensors. Problem solved!”
Hey, cooljess76: Is that John Tuturro bowling with a backwards baseball cap and why? Just curious

Rear camber isn't as much of an issue for tires as the toe. Toe is what really tears the tires up. You can get adjustment plates to get it back in line a little, there are also raised subframe bushings.

I put the thickest spring pads (upper and lower) I could buy and then made 3/8" aluminum spacers to raise the back end of mine. Made the car much better.

I have that exact suspension setup on my ti and while there was a slightly noticeable increase with negative camber, it really didn't look that bad and after about 8k miles on the suspension, I haven't noticed any abnormal wear on the tires.

After lowering, the rear camber on mine came in at about -2*. The specified range for rear camber is -1.5* to -2.5*, so even if it is -2.5* to -3*ish, it's not that far out of range. I'm also running 17" wheels, so that might make a little difference. I'd have it put on an alignment rack just to see exactly where you are with the camber.

Thanks for the input. I'll post pics tomorrow so you can get a better look. Maybe you can compare mine to yours?

I am also running H&R sports. The static camber wasn't too far out either. Toe was in a bit from spec. The issue that you run into is the camber and toe curve during compression and rebound. That's why you have to run lots of spring and damping on the E30 style rear suspension. Need to keep it from moving.

[cooljess76]

As truckster said, the tow really tears tires up quickly. Camber causes them to wear unevenly. The problem myself and most people have is the inability to rotate tires. Most low profile tires are directional, so the only rotation would be from front to rear and vice versa, unless you dismount tires from the rims and have them remounted and balanced. Ireland engineering makes a nice weld-in kit that allows you to adjust tow and camber. There's a couple variations of this kit, the e30 guys have been doing it for a while now.

And yep, it's "Jesus" from The Big Lebowski. "Eight year olds Dude..."

Went thru the same on my old e12 after lowering, chewed up the first set of tires really quickly. I corrected the toe with offset trailing arm bushings. They're called camber correction bushings, but there's no reason not to install them offset fore/aft to correct toe instead of up/down to correct camber.
Anyway the final result is I corrected the toe, left the negative camber, and the car handled great and did not wear the rear tires any faster than the front.

I think I'm about to do the same with the ti since the rear is toed out a little.

[spidertri]

Stock rubber correction bushing should have a better time keeping the alignment because the rubber is able to twist when large forces are exerted on it. Whereas the urethane options are forced to rotate because it is a harder material. Obviously the rubber would just "un twist" where the urethane would be rotated into a new position.

IE just came out with a new weld in adjuster design that now uses interlocking plates. Should be able to keep the alignment a lot better than the old design but it doesn't look as easily adjustable.

Hey guys,
Sorry for the delay. I'll get pictures up on the rear end. I was out of town.

[geetarspaz]

im interested in everyone's thoughts as i'll be upgrading the suspension and lowering mine eventually

I just listed these for ease but there are other companies make as well.

Just took a few new pics today

I installed one kit like that from bimmerworld and the tires last longer and its better the camber/toe values!! but it was a litlle hard to install correctely!! i have eibachs sportlines and bilsteis b8 (all sports)

have you solved rcv7?

[eurohb]

How do we go about installing this? does this give a tad bit more camber? or does it make it straight?

[RCV7]

Thanks for all your hep. I decided to leave it alone as the tires don't seem to be wearing uneven.
