I've been reading through this thread (you'll find I asked the same question there), pondering spring rates, and wondered where you guys wound up with your Penske and KW Variant 3 setups. Are you still rocking your present handling balance, and if not, what kind of experimentation have you done?

I had a very similar setup to Tweeter (Ground Control with 650F/750R), which I might have been using to compensate for the poor compression and rebound dampening of the FG2s. As they say, the best thing to do when your suspension sucks it to prevent it from doing anything.

Now that I have KW Variant 3's, I'm debating the following spring combinations, based on the Swift catalog:

Option 1 (Soft 46/54 ratio)
- 2x Stock KW V3 front springs (8" length, 70mm ID, 100 N-m / 574 in-lbs)
- 2x Z60-228-120 rear springs (9" length, 60mm ID, 120 N-m / 672 in-lbs)

Option 2 (Medium 50/50 ratio)
- 2x Z70-203-120 front springs (8" length, 70mm ID, 120 N-m / 672 in-lbs)
- 2x Z60-228-120 rear springs (9" length, 60mm ID, 120 N-m / 672 in-lbs)

Option 3 (Stiff 46/54 ratio)
- 2x Z70-203-120 front springs (8" length, 70mm ID, 120 N-m / 672 in-lbs)
- 2x Z60-228-140 rear springs (9" length, 60mm ID, 140 N-m / 784 in-lbs)

I'm lowered pretty far, so the only two things that I'm truly certain of right now are a) I need more rate in the rear to prevent my 285s from rubbing on hard, sustained corners, and b) I want less understeer (which I may be able to derive by tuning the shocks). Presently, my KW Variant 3's are set to stock settings, which are:

Front Axle
- 0.75 turns from full hard for compression
- 0.75 turns from full hard for rebound

Rear Axle
- 1.0 turns from full hard for compression
- 1.0 turns from full hard for rebound

Another important question is, has anyone with a KW Variant 3 found out how much spring is too much for the KW Variant 3's rebound dampener valving?
