Kerrrslammed - GC Coilovers complete!

[MisterMiniS]

UPDATED!!! Added some autox pictures.

FINALLY got the coilovers installed. I got them done late last night, so I took some quick cell phone pictures this morning.
Anyways, camber is not even maxed out. The ride height is set at halfway, but if I go lower, I will rub (need some fender rolling). Today or tomorrow I will throw my race wheels on there and see if they rub.
Autox race saturday, so I will be there to test/tune.



















And here are some of the professional photos that were taken. Right now there are only ones up of my girlfriend.

Very exciting! What spring rate did you go with?

[MisterMiniS]

550 on the fronts. 875 on the rears. I will be only running a front sway and no rear. We will see hoe everything goes at the race saturday.

875lb rear is pretty hefty. Are you going lightened? How are you expecting/hoping the balance to be? I'm running 600lb f/800lb r and I'm pretty damn tail happy.

You may want to put that sway bar back in just for turn in and to keep the back end tied together. The rear of an e30 is really really sloppy without a rear sway.

Are you running slicks?

or 1500lb springs.

OP, you will want the stock rear sway. At least try it both ways.

So, the autox this weekend will be run with stock sways all around. Current plan is to beef up the front and remove the rear, but that all depends on the handling. I would like to get the ride height set so there is not rubbing, then mess with the shocks, camber and sway bar. Time will tell.

[Bimmerman325i]

Beef up the front, keep the rear bar soft but present.

Why do you want to remove the rear?

[blefevre]

I dont think 875 is stiff enough for no rear bar. Keep it stock.

A lot of people run no rear bar but stiff springs on E30's.

Yes, but the reason why is to avoid rear wheel lift in corners, and they're essentially slapping a band-aid on a punctured artery; it's not the right solution.

E30 rear needs more travel than common performance shocks give-- that's why Vorshlag used their triple adjustable remote reservoir 4300s on their 318is autocross car. Problem most people do is use a good shock that has a very limited travel range, combine it with stiff springs, and then take out the rear bar because it's imitating a dog pissing. A big part of the solution is getting more travel in the rear.

Confused. So he should run soft springs and no bar? I get the idea is to avoid rear wheel lift, I just am confused on what you are saying.

Yea, that was stream of consciousness.

He wants the softest possible stiff springs and bar combo, if that makes sense. Stiff springs + bar + more travel is what I'd aim for, sways are good things. Honestly though, I'd clone Vorshlag's e30 autocross suspension build as much as I could. That setup was pretty choice, and since OP is running race tires, he won't have as many compromises (no LSD, etc).

McLaren laughs at sway bars!

But yes, that is what I thought....but how do you get lots of travel from 800+ rear springs?

Ha, they didn't on the McF1, and they have a system that acts similarly on the MP4.

How VS did it was remote res damper, so that the damper body itself had more available travel before hitting the internal shock bits combined with taller springs and IIRC tenders as well. Worked really well.
