Maybe YOU should do some research, are springs are NOT progressive rate and you CAN cut them. You should never cut a progressive rate spring. Alot of people cut thier springs to produce exactly the stance they are looking for.Brad said:Having 18" wheels doesn't change the diameter of the total wheels size...
Also I don't understand why you people are cutting your springs, it's just stupid, they're not designed to be cut and still do their job whereas a lowering spring can lower the car and still perform.
Pony up the $200 do some research and do it right for christs sakes, cutting might get the ride height you want, but you lose all predictabilty and performance of the spring.
On edit, I believe you can cut a progressive rate spring as it still keeps the same level of riditity over each spring, but the stock springs, don't cut them.
