I just got some new rims for my dc2 and they are 16 inch rota's with Nitto NT450 205/50R/16 tires. My car isnt lowered at all, but i do have ground controls all the way up at stock height. Ive noticed when i make turns sometimes or go up or down steep hills or bumps, i hear a kinda grinding loud sound? is this the tire rubbing against the fender walls? do i need a smaller tire? What is this sound?

I think it could be two things:

1. Your tires are rubbing your fenderwell. This is unlikely though since you're at stock height. I could turn my wheel almost to the locking position before I heard rubbing, and I was dumped on 16's. How far can you turn the wheel before you hear the noise?
2. Did you replace your shocks/struts when you put in the ground controls? I'm not sure if you're putting stress on them sitting at stock height, but I also had ground controls with stock shocks (my car was race dropped) and when going over bumps I could hear loud creaking noises coming from the shocks. It means they're wearing/worn out.

 

maybe i should replace the shocks.... since im riding on stock gsrs

 

if you were rubbing the fender wells, you'd hear a scrap sound when your chassis dips. Have a look at your fenderwells for wear to verify. The grinding sound you described may be related to your suspension.

any reason why youre using 205/50R/16 tires?

205/45-16 is the proper size (wheel diameter closest to stock without affecting the speedometer reading).
The sidewalls are a bit higher with 50's.

 

what size tires are u using they might be too wide

 

thanks for all the help guys... im gonna get it checked out asap

 

what's the offset on the rotas?

 

ill check it out... im not too sure

 

You have the wrong size tires. Put on some 205/45-16's and it should be alright.
