How to Modify front JOM coilovers to go lower?

[acolella76]

4in seems like it will be crazy low, unless you can get them to work with the JOM adjusters.

a 4 in spring will let the rear sit proper for early body e30s

not to go offtopic but will these be lower than GCs?

A lot of people don't even run the adjusters

Oh yeah I wouldn't run adjusters, but I guess i'd buy 4 or 5" springs to get it low enough. I found some TC Kline springs on cl for $100, but he didn't email me back about them yet, and I have yet to find a pic of how just the springs (not their coilovers) sit...anyone have any idea? I think it's like a 60mm drop in the front, no clue about the rear though..

^ easy fix to the oil pan problem, just raise your motor till the pan sits level or higher than the sub-frame. then- install a skid plate that not only protects the oil pan, but also the steering rack, sub frame & the sway bar from ever getting caught on something.

all of this and you can achieve this:


NOTE: this is with 195/60 R14 size tire. so with the proper wheel setup you can be even lower. IM the guy that did the "method B" for modifying the JOM's

you know the fronts go low as FUCK right? When installed correctly the oil pan will hit the ground before the adjusters are all the way down. Not sure why anyone would need to go lower...

The back sucks. I don't run adjusters or pads and it's about 1/2-3/4" above the tire. Going to buy new springs for the rear anyways since the rates suck

Anything for the back, other than removing the spring pads? I might get some but i'm worried about my early arches and the back being too high.

Its easy, cut off your lower spring perch, from there you have two options, either

A) cut it all the way down smooth with the strut tube, then weld a circle at the desired height (essentially a new perch for your adjuster) and rock it. or...

B) Simply trim the lower perch down to just the weld, and use it as your perch, guessing it'll gain you about 1/2 to 1 inch extra play.

This guy did method B.




Ground control actually makes a weld on perch, if you feel the need to have something more stable than a weld holding your spring up. Its my recommendation to get the perch from GC for safety reasons.

Ive heard its been done, and it gives much more adjustability, but how exactly is it done? Any extra info or a write up would be great especially with some pictars
