Cold wound of the highest quality chrome silicon material, shotpeened, and then powdercoated... 3/4" average drop front to rear, with the front settling in about 5/8" to 3/4" drop and the rear about 7/8". Why the difference? We think all the rake from the factory looks silly. If you only want a moderate drop to close up the wheel gap, look no further.
Linear design front and rear, slight increase in rate over stock in front and rear - they play well with OEM shocks/struts, Koni Yellows and Bilstein SP's.
The ride with OEM shocks/struts is by far better than with OEM springs...
The front and rear spring rates are the same - a combination that we have tested time and time again and that we feel works the best... It allows you, the user, to dial in whatever you want with a rear swaybar.
Being that they're cold wound, they won't sag in, and the rates are more predictable... These are top quality springs!
