The good thing about upgrading the ARBs is you can keep some of the sharpness with the dampers set softer.

Never tried, but it'll roll less at the front with stiffer springs and so understeer. It's not the rate, but the amount of roll that's less (though I guess the rate must also be less, depending on how you measure the rate ), so the differing spring rates will have an effect mid corner, not just on entry and exit. I suspect you're right: you'll have to adjust the dampers more to get the same effect because your front springs are harder. Try it and see.

I wish I could remember the Bilstein spring rates.

Good point on the soft front vs hard rear.
Might give that a try I have them same front and back at the moment.
Rebound is the same all round with damping on 9/24.
Springs are 350lb all round.
I have stock ARB's but may go with the Gendron adjustable front.
I do get some wheel arch rubbing at the front on hard cornering so need to reduce the front roll.

On my AST advanced suspension coilovers I have always two 2 clicks difference between the back and the front (I can adjust from 0 to 12 clicks).

You just control the amount of oversteer or understeer you wanna have in combination with your individual gusto and the make of your S2K, like the 2000 model that I have is generally more stiff then the new ones etc.

Please also keep in mind, that in rainy or misty conditions you want to put your dampers a little bit more on soft, I found out through testing (by an amateur race driver) that 2 clicks less (which means softer) I have much more grip in damp conditions versus the "dry setting".


Just my two cents,

Andreas

My 06 OEM dampers where dynoed and tested by Nitron at 245 lbs front and rear!

binning the front arb is a standard nova trick,

use the hardness and lowness of the suspension to keep the roll to a minimum, why risk upsetting the wheel that has grip when the other wheel is unsettled

mikey k

That is the counter and the reason why I have not upgraded my front ARB.
A decent coilover set up right ought to negate it.

Dembo

Yes but an ARB has a big effect on roll, and a small effect on ride and ability to absorb the bumps. Whereas reducing the roll the same amount with springs results in a much bigger negative effect on ride and bumpy road grip.
