Shorten the strut tube (cut and weld).

Lol. You dont have thats only if want to drop the car like 4 inches.

Actually if you want to be anything even remotely low you should shorten the housing and put short body koni's in.

Suspension travel is paramount to handling well at any ride height. When the strut bottoms out (without shortening) and the spring rate quickly approaches infinity handling is right out the window.

+1. You can lower the car fine for either reasonable conservative look drop or for handling with the stock perch.

GC's are not complicated. Remove strut, put in koni. Put perch on stock perch. Put ERS spring on GC perch...

The rear is even simplier, if you have the shocks already what you are using. Unhook the top of the shock, lower trailing arm, remove Spring, put perch on the nub, and put the spring between the perch and top nub...

I would call my car "remotely low" and I dont have shortened housings. I think it is totally unnecessary unless you have a dedicated track car and you want every last bit out of it. I'm running bilstien sports and have not bottommed out once. I have even run it about 1/2" lower up front for a short while with no problems.

here's a linkso as not to whore the thread.

basic installation instructions for front strut.
-remove strut from car, remove spring, remove insert, etc.
-Use a hacksaw or sawzall to cut off the stoc spring perch but leave the weld where it is attatched to the tube. The threaded sleeve will rest on it.
-clean it up and paint it with por-15 or some other rust resistant paint.
-slide the threaded sleeve onto the strut tube.
-install strut insert
-figure it out form here. it's easy.

You don't have to hack the perch but only benefit is if you are lazy like my PO or want to swap back to H&R Sports without buying new strut housings.

If you are using ground control's short koni front inserts you will put the spacer they should have provided in the housing first then the insert.

I think I cut about an inch and a half or so out of mine when I put them together. I have adjust ability to go about another inch lower in the front but I've already broken one oil pan and decided not to go any lower.

What length frt and rr springs are y'all going with?.......

What length frt and rr springs are y'all going with?.......

6" front and rear is standard. I think that I will pick up some 5" rear springs at some point to give a little more drop, I am maxed out right now and its still not low enough in the rear.

Ive heard some using 5-5.5 in rears.....

do you have pics of yours that shows the drop.......so you run 6 in rears.

[rwh11385]

5.5" is very common in the back. 5" is awful short, whereas 6" makes it hard to drop down low but I liked the length.

GC kits consist of 6" fronts and 5.5" rears
