Default RS*R Superdowns uneven...

I didn't notice it till I mounted my wheels but the drivers rear is about 3/8" lower than the rear passenger side. This is causing me to rub on the driver side but I have plenty of clearance on the passenger. Any ideas?

Springs installed 3 weeks ago.

maybe you put the wrong size springs on? The smaller sized ones go in the back and the larger ones go in the front.

Might be installed wrong on one of them or the wrong spring on that side.

I'd back out some of the bolts on the lower arms and re-tighten. Sometimes if you tighten those bolts without any compression on the spring, it may force the arms to sit unevenly.

It seems that on some cars theres always going to be some degree of a lean after lowering..
On my previous BMW.. when I lowered it... it had a lean a little under 0.5"...

Is lowering the only cause? or did you get new aftermarket rims/tires? offset? size of tires?

Just read your first post... and I see that you got 20s.. and 285 is pretty wide...

At this point it almost seems as if to cure the rubbing, either go back to stock height, get smaller tires, or get smaller rims.

STOCK: 235/45/18x8 with a 45+ offset backspacing is 6.3" overall height is 26.3"
YOU: 285/30/20x10 with a 40+offset backspacing is 7.1" overall height is 26.8"

1) your new rim/tire is 0.5" taller than OEM
2) OEM is 9.3" wide tires; you're at 11.2".. thats 1.9" wider than OEM
3) Your new offset makes the rim sit further into the fender, meaning the rim and tire get closer to the inner fenderwall.
4) you're lowered on springs maybe 1-1.5" lower than OEM

If you're set on the rim/tire combo... just go back to stock height...

were you rubbing when you were running stock springs?

I can't go back now...The car looks too good lol. Fitment is aggressive but nothing crazy imo. I am going to make a spacer​ for the spring to try and level it out. Rolling the fenders today too so hopefully that will go good and free up some space. I'm not worried about the inner plastics rubbing, its the outer lip cutting the tire that concerns me.

Looks nice and flush. Are you rubbing in the inside or the outside fender?

If its mere feathering of the tire, its ok. That happened to me when I slammed by tacoma back in the days. After I rolled the fenders, all was well.

i noticed a small amount of rubbing on the inner plastics but nothing to worry about. I rolled the fender (driver side) and I don't have anymore issues. It's tight, but the fitment is on point!!
