Fixing FF understeer

[Home5quirt]

Hello everyone.

I need help with making my Spoon Civic understeer less than usual.
I'm getting confused by the descriptions of the toe angle and all that other stuff.
So if you have a solution, please help me.

There are a number of tricks you can use to cure FF understeer, first is to put the front ride height higher than the rear. (For e.g front 0, rear -20 etc) Then you need to make the front suspension stiffer than the rear like 9.0 and 5.0.

Putting the front damper values higher than the rear also helps with oversteer an example would be 7 on the front and 4 on the rear.

Then for the toe setup front toe doesn't really matter much a bit of - helps with traction. Where as on the rear you want to start at about -0.30 and add -0.10 more until you car starts to oversteer a bit.

Hope this helps but if not heres a base setup I use on FFs using the above tricks.

Ride Height: Front 0, rear -20 ----------- Camber Angle: Front 1.8, rear 1.0
Spring Rate: Front 10.0, rear 5.5 -------- Toe Angle: Front -0.05, rear -0.35
Dampers (Extension): Front 7, rear 4
Dampers (Compression): Front 7, rear 4
Anti Roll Bars: Front 5, rear 4

Brake Bias (ABS 1): Front 4, rear 7

^GT5 setup.

Level ride height, stiff front springs, soft rear springs, 6/6 bound, 9/9 rebound, 1/7 anti-roll, 2.3/1.8 camber, 0/+2 toe (if GT3's works as GT4's does, I can't even remember).

Should work well enough.

Thanks, Rotary! It helps a lot more than what I've tried.
