So I purchased these Racing Hart's off of a friend and at the same time I switched from the Eibach to Tein lowering springs.I also installed an aftermarket camber arm to reduce camber. It seems like when I am driving and I have a passenger in the car the rear driver side tire rubs on hard bumps. I have factory shocks and I am a large guy (250lbs).
Is it because my wheels are too wide? I have seen other tC's that are slammed with the tires way up in the wells.,
Should I roll my back fenders???

 

got the same problem cuz im on 18's and tein is 1.9 in the front....almost 2 inch drop plus ur weight = rubbing.....get your fenders rolled see what happens...

 

oh yeah i forgot to say h tech! lol!

 

its probably only chewing the fender liner a bit, but if you're handy and want to reduce/eliminate it heres what helped mine:

- turn your wheel to the right so you have some space to work
- take down the fender liner just enough so you can get to the hidden 10mm bolt that holds the bumper to the fender
- grind the inside lip that the bolt holds together. the idea is to get rid off excess material so its right up flush to the edge of the bolt head
- button the liner back up, pulling it towards you as you tighten the remaining 10mm's
- using a heatgun and some leather gloves, heat up the liner just enough so its a bit pliable and knuckle it towards you again, we're molding the plastic a bit tighter to the metal fender so there's more clearance for the tire

Work it a bit at a time and don't go nuts with the heat gun

 

My rear driver side used to rub also... I rolled my fenders a little and it fixed most of the problems, but didn't fix all of them, I still rub on big dips and really aggressive curves.

I'm on 18x8 with 35 offset dropped on hotchkis.
