I know it is possible to install coil over sleeves without cutting off the stock spring perch however; does anyone have a picture or info as to how well the coil over sleeve sits in the spring perch? I realize that you loose a few inches of adjustment.

it sits well enuf......

but....

just go to a local machine shop( if u can't diy)...cutoff the oe perch and leave a bit of the ridge on....

then the sleeve just sits on that....its much less ghetto than keeping the whole oe perch on. U don't even have to weld it up.

Yeah, I don't have the tools to DIY. If it sits well enough to be safe and driveable that's all that maters for now.

I've got JOM coilovers and this thing gets in the way of me adjusting them. Can / should I just cut it off?

[JRKOUPE]

yes yes yes

[dougie30]

i just bought some JOM coilovers, will i have to do this to my car? or does the JOM kit come with this already done?

sorry iv never done any suspension before so im not sure why you would have to do modify your strut?

You have the choice to cut them off or not. People cut them cause the spring perch gets in the way sometimes and you can modify the strut tube to make the JOMs go even lower. I choose not to cut them just in case i wanted to turn the car back to stock. Im still able to adjust up and down, its just a tad more difficult, which isnt a big deal to me.

and a word of advice for the JOMs. DONT PUT THE FRONT ADJUSTER ON UPSIDE DOWN! :D
lol lots of people have done that on here. even me.
Follor the the directions here on the forums too. they help out a lot.

This is a rode less traveled. I'm not going to give away my trade secrets on how i shortened the bilstein sports. Every part of my coilover setup is offered for sale by me.

First we shorten the strut tubes 1.9" and add a collar along with AKG sway link tabs. Welding done by Chris Castro of Castro Motorsports.







Pics installed with my GE camber plates and coilover dust boots. 6" #300 springs






Rear installed with GE tall RSMs 4" #800 springs (14lbs of boost and a stereo system makes the car squat hard)







Rear all the way down and fronts all the way up. Will be switching to 7" springs

is there a thread on here on where you can buy your set up?

Thanks alot! yea i think im going to keep mine unmodified as well, and thanks for the tip about the front adjuster. How can you tell if it is upside down or not?

[einstein57]

Out of stock. I should hopefully have some by next month.

how much does this cost? for your set up?

the spring will look really compressed, but the adjuster should sit over the strut tube within the spring perch.

It should also be VERY difficult to put on if its upside down. I dont know how people still manage to put it on when its difficult, but youd be surprised.
