Lowering kits options

Sure but how tall are the tires? I think it's raked because of the springs on there, not the wheels.

It does make a difference because with the QA1 UCA's you'll be able to get a decent alignment even after you lower the car. I would say that if you intend to lower the front you'll probably want larger torsion bars up front though. Something in the 1" to 1.03" range is usually pretty good for a street car.
Rear's are 27" and fronts are 25". Full specs:
Front Tires: 235/40 ZR/18. Rear Tires: 245/50/ZR18. I don't know squat about the springs. This was a car that was re-built then sold to a dealer. I bougth it from the dealer. I've tried to get all the information about the car from the builder but I can only get so much information.
