question do i still have more room to raise my st coilovers???

i am in a confusion right now.. my car is a e90 lci.. first im rubbing on the rears. setup is

19x8.5 et25/ 19x9.5 et 20
235 30 19 / 265 30 19 nexen n3000

all fenders are rolled and pulled.. im rubbing to the point where my sidewall has all gashes and chunks coming off.

im trying to adjust the rears and it seems like i cant go any higher. the rings are getting harder to turn and i have no threads left...

here is a pic of what i mean.. do i still have more to go higher even tho theres no more threads left at bottom of the perch?? sorry for the noob question..

Your offsets look way too aggressive; especially with those wider rear tires. That is the source of your rubbing.

To answer your main question; no, you look to be at max height in the back.

I have KW V1's on my car and your rear looks like it is at the max height allowed by the kit. I am willing to bet you would have rubbed just as bad with your stock suspension had you loaded the car down so that it compressed farther.

The bottom line is yours offsets are wrong and are holding the wheel too far out. As the suspension compresses it allow the tire to contact the fender.

Get new wheels with higher offset values.

Adjust your camber if you haven't already. You can get up to -3 degrees in the back and -1 degree in the front naturally. That should take care of your issues.
Also, you are at the highest setting on those STs. They automatically drop your car 1.1 in the back when you install them.

I think there has to be some more threads on the rear perch. Its stupid hard to turn so you might have to re-do the rears and adjust the perch off the car. Unless the perch really has no threads left but seeing pictures there are more threads?

that's close to max height... mine are adjusted (like yours) so the bottom spring perch is flush with the bottom of the mount...

those offsets are too aggressive for an LCI... you can run 255s in the rear instead... or try to grind off the inner fender lip...

another option would be to buy damping adjustable coilovers and stiffen the rear up...

Thanks guys for the info.. in the end I had to take off my rear spacers and end up with 35 et now.. really thought I can pull it off with pulled fenders but in the end it's just a pain.. really wish u can go to stock sport height without taking the perch out.. next time I'll definitely go lower on tires.

What is your rear camber at? You can make it work with more camber, or use a smaller tire or smaller spacer.
