Suspension setup for staggered tire/wheel setup

geeitup · 05-19-2023, 05:56 PM

I was wondering if I could get some advice on a track day setup - thanks.

I'm running a staggered tire wheel setup for track days and feel like its understeering and lacks turn-in. I know I'd be better off going square, and I may at some point. But for now I'd like to make some adjustments to help. I was thinking more front camber and possibly raise the rear a bit.

Here's my current setup:

Wheel/tire Hankook RS4s. Front 9.5" +15 265/40R18. Rear 10.5" +15 with 15mm spacer 295/40R18

Ride height 26 1/2 front, 26 3/4 rear (lowered rear more than front to shift weight to rear)

Alignment
Front camber -2.5, 05 toe
Rear camber -2.0, .29 total toe

Hotchkis sways, rear softest setting
BC Racing Type DR/DS true coilovers Swift springs 12k/8k.

SPL arms/links everywhere

Thanks all.

more front camber
crank the caster to max
less rear camber?

but yeah . . . you can run a 10.5 with 275 or 285 or even 295 up front easily

some folks run 305 all around

My caster is 5.9 - so more?

Play around with air pressure in your tires. That will help. Try stiffening the rear bar.
