Gents,
Hoping to get some feedback on how to get back to some more neutral handling after I overhauled my suspension.
Currently running Penske 7500 shocks on 4 corners, Sprint springs (10kg/~570lbs front (10 inch length), 12kg/640lbs rear (10 inch length). Have all other suspension mods inc. beefy swaybars, trailing arms, beefy rear tie rods. Obviously with the S/C up front we have a bit more extra weight to deal with.
Given that I slapped these on without much thought car's handling has changed quite drastically. From being somewhat neutral to understeer happy, it's now very tail happy. Not necessarily a bad thing for the fun factor but really a nuisance when you're trying to get around a track quicker than the debris collection truck.
Need to get a bit more neutrality back in, maybe soften up the spring rates also and get the rear under control. Right now car is a bit unsettled (front and rear).
I'm thinking of breaking the pattern of rear to front spring rate bias and going with 500lbs shorter springs in the rear and 550lbs in front (move up to 12 or longer springs to take up some shock acreage that's going to waste right now).
Unfortunately can't quite ditch the rear hotchkis sway bar (threw away the factory one) so need to work with it in place.
I'll get the car properly aligned and corner balanced.
