S197 GT Spring Rates and Heights (no guessing allowed)
Trying to keep my car in F Street this year, but want to upgrade springs if legal. I want to get the benefit of the full 2010 track pack car if reasonably feasible.
Do any of you have the spring rate specs for a 2010 GT Track Pack II car? I have a vin for a 2010 Track Pack II car and my vin for the Track Pack I car (3.73 rear axle package) So far, the springs and sta-bars seem identical. Both cars call for AR33 5310 F (Yellow) for front and AR33 5560 D* (Tan) for the rear from the dealer catalogue. I know the rears have a rated spring rate of 156 lbs. I don't know the spring rate for the Yellows. Both have 36.4 mm sta-bars in the front. If this is true, the only difference seem to be the the strut assembly between a Track pack I and II car. Any additional info would be helpful.

If the two Track Packs are calling out the same front spring by part number and tag color there is nothing to gain there, and even if there was I think you'd have to convert the rest of the car to match whichever Track Pack you picked the springs from. Aftermarket springs are out for FS and the 2014-only FSR class; they'll send you to STU, ESP, SM, or CP.
The strut assembly probably doesn't matter, since you're free to swap struts and shock absorbers (there may be some limits - I'm not entirely sure what damper allowances exist in F Street).
