Just installed a set of the Whiteline Control series springs on the Colt last weekend. Ive been commuting the car to work all week, and I must say that I am VERY pleased with several aspects of the springs.
I removed my original 1.5L springs and installed the Whitelines on the 1.5yr old KYB GR2's, and the car was lowered approximately 2" in front, and 1" in the rear measuring from the floor to the fender lip. (I think they say 1.6") Im sure the suspension will settle somewhat over the next couple weeks.
I didnt get an alignment yet, but everything seems fine, the wheel is still centered, and the car tracks correctly down the road at 125mph
Handling has improved 300%, the car responds like a fricken go-kart!!! The suspension doesnt tuck hardly at all on hard acceleration, and the tendecy to torque steer and change lanes has diminished. I can still fit 2-3 fingers between the tires and fender lip, and the car doesnt look retarded-low. The ride is firm, but not harsh. Most importantly, my slicks clear no problem, even driving on city streets.
I would recommend these springs for a street driven car in a heartbeat. I havent tried all the other suspension options out there, but the improvements I have seen with these springs is a good mix of all worlds. The aussies did their homework.
Will post pictures soon!
