I bought some spacers to fix my ride height problem. I turns out that i will have to have the spacers machined to fit the bilstein spring mount. I think it would be better at this point to get a set of cheap sleeves. It will give me more adjustability, and I can use either the stock bilstein perches, or the spacers to support the springs.

My shock body is 53mm and the c-clip is 53.3mm

 

Are you sure about this? They fit my KYB shocks, which are identical to stock shocks, so any spring/perch of that size and shape should work. Or are stock shocks the bilstein design?

Sorry about this.

 

No worries man. They can be easily machined to fit perfectly. I'm just trying to see if i can get even more adjust-ability for the same price. I want to avoid buying a cheap coilover kit for the sleeves only to have them not work. I can have these spacers modified very easily.

 

Just buy the e-bay kit and see if it works, its cheap anyways.

 

I used an Omnipower coilover sleeve kit for mine. Fit like a glove. Almost interference fitment.
