I have a 93 SI with Ground control coilovers and Koni Yellows, I also installed an ITR rear sway bar but am still unhappy with the cars handling. I feel like it could deffinatly have less body roll so I am thinking about upgrading to stiffer springs
Here are my rates now:

Front: 200.64.67
Rear: 180.64.44
(i am unable to read these lol)

What other things can I do to get the best handling out of this car? Every one says "oh the GC?koni setup is soo stiff" but even on full stiff it isnt that bad and thats prettty much where I keep it daily

 

bushings. change all the old bushings out with brand new rubber. and get an alignment. rear camber can have a lot of effect on turn-in feel. 1.5neg at the max seems to work well for turn-in feel.

 

Best solution is to get better tires. or get stiffer rear springs. It will help your car rotate more but... you have to give up something to get something. In this case, your car will be bouncier and other people suggest some safety precaution because the rear end will be more suceptible to spin out under some circumstance. BTW, are you using a reinceforcement kit with the ITR bar? If you are using an ASR rear brace, you could always upgrade to a thicker sway.

I never thought about replacing the bushings but I will have to give that a try. Also the car hasnt had an alignment in quite a bit I will do that as well, I dont have much in the way of negative camber though.

I dont think the car rotating is so much of a problem as is body roll, its rather un inspiring when the car starts to lean coming into a corner.

Also since the rear bar has been installed the back rotates alot it seems, almost like rear steering....feels kind of odd I am used to RWD though so its hard for me to diagnose. I have had RX7s all my life

 

What kind of seat do you have? Upgrade the seat.

What makes you think that body roll is bad for handling? What makes you think the handling is bad in your car? Stiffer suspension is a NEGATIVE side effect.

Better tires will give him MORE body roll..

Stiffening the rear will give you oversteer. Are you surprised by this? How are you going about planning your suspension? Are you just throwing on parts based on internet forum recommendations?

 

/\ What that guy said. I'd go with better seats. Your car shouldn't have body roll. Maybe your body is rolling?
