I almost regret getting the Pro adjustable shocks and struts now... almost. :)

Few questions for you:
  • What is different between the front pro adjustable shock with a Steeda spring and the front coil over (aside from height adjustability)?
  • The front adjusts stock to -2" whereas the back adjusts -3/4 to -1 1/2". I take it that it wasn't easy to get the rear to adjust from stock to -1 1/2". Do you see a way to get the rear up to stock height without compromising the ride or function of these pieces? Reason I ask is to get the full benefit of the front coilover range in the event I wish to stay stock height in areas not friendly to cars that ride low.

What front spring rate do you recommend with these for Autocross/HPDE with a GT? Been waiting for this kit to come out, definitely getting it

The web site shows 1000-1100 , for the rear kit, I assume they're the same in the full kit. IF they will offer this with lighter rear springs I'll order tomorrow.
On that note TJ can you send me the forum discount code please.

You are correct. With a 250lbs/in front and the 1000 to 1100lbs/in rear rate you will be surprised on how good the ride quality is.

What are your objectives in the ride and handling dept?

All the best,

Steeda Tech

Ok thanks. I'm at 240 front and 980 rear and can confirm it rides quite well with good dampers (I have the fixed valve pro actions).

Probably around 200 or 225 front would be good for the Eco.

What about a stock GT PP looking for a 1" drop. It's my DD and I don't track it. I'm looking at doing a 19x9.5 square setup in the future.
