Was getting inlifting on tight corners, so I disconnected the rear sway bar, now my car is understeering? Should I compensate for it in rear spring, and how much? How can I get rid of inlifting without pulling rear sway?

Setup:

17x9 Nonstaggered 245/40/17 RE01R's
Ohlins MCJ 580lbs front and rear

Alignment:

Front: - 2.5 camber, 0 toe
Rear: - 2.8 camber, 0 toe

Front: 7 clicks from full stiff
Rear: 12 clicks from full stiff

Car is about 3/4" lower than stock, everything else is great. Thanks in advance for any input.

Smaller diameter rear bar or larger front bar?

 

larger front yes

 

larger front and more spring in rear.
I have 950 rear spring and 900 front with mugen front bar and no rear.

mind you its a race car and has not seen the street in two years.

 

I would start adjusting what you have now by stiffing the rear shocks. Adjust camber also. You can always add more spring later.

 

My friend just gave me some 700# rears I'm going to try out.

 

Gendron front swaybar is what many use to keep the inside rear planted.

BTW...have your tire temps been pretty even across the tread with those camber settings?

 

Don't have any temp numbers yet, this is a new setup for me, I'll find out next weekend. Do you have any suggestions...

 

You don't say what your activity is: Autocrossing, HPDE, Drifting, Racing, Street?

If it's street, slow-down!
If it's drifting, I haven't a clue.

For any of the other activities, I'd re-connect the rear sway bar, and get a good front sway bar and put it close to full stiff. I use the Gendron solid bar, and it works like a champ, although you'll need smaller endlinks to go full stiff. Then adjust out any understeer you get with alignment and shocks. If you can't get it neutral with alignment and shocks, go with more rubber up front.

I do not believe I'd go stiffer springs in the rear, as I believe that would make the problem worse. I'd be curious to hear the logic for stiffer sprigns from anyone who suggested them, though.

 

no difference between stiffer springs and no bar ...and same springs and bar. You are compensating with the stiffer springs when you remove the bar . Make sense?
