regardless of who wins your argument...I'm cutting a half coil in the front and rear, and I feel very safe in doing so, or I wouldn't do it...the replacements will not do what I need them to do...this is a keeper for me, and I am the only driver...I will not go any further than the half coil, because other parameters will change too much...I am only looking at lowering it an inch, maybe just a little more, then upgrades the shocks...that's it...nothing more...cheap mod for me, and I think it will help just a little in handling on the track...or I wouldn't do it at all...moving on w/ this mod...thanks for all your posts, pros and cons......
