Well, had the GYs replaced with NT05s and the fronts (285s) are now making contact with the air duct at full lock. I know quite a few people run 285 in the front and I never read/heard of issues like this...

The shop that does work on my car is suggesting to install, for a lack of a better word, a bracket that will cut down the turning radius to just shy of the contact point with the air duct. Anybody notice the same issue?

Strange, stock ride height? My car is bone stock except the nt05's, 285's up fronts, zero rubbing.

bright1984

Yep, stock ride height...

Wheels are alligned and camber and toe are stock spec?

Are you sure the air duct isn't misaligned in any way?

I have run 285 NT05 fronts for two years and never had this problem with stock height and stock or larger GM brake ducts. Now dropped ~1.0" with LG drop-spindles and LG brake spindle ducts (larger than stock) and no rub.

Are you running aftermarket wheels? Maybe it is your wheel offset?

They wont rub on the duct when you put the car back down on the ground. With the car lifted it will. Same tires on mine and I'm lowered a bit. I have a full thread about these tires. Just search my name and NT05. I have tons of pictures. U might get very light rubbing on the inner fender from the outside edge of the tire if you drive it hard. Two autocross completed on these same size and type with no problems. Again check my previous thread.

bright1984

yeah, alignment and wheels are stock

bright1984

doesn't look like it but will double-check

bright1984

Thank you, Sir. I'll be sure to check out your thread. Hoping to avoid any unnecessary work here.

I have the 285 Nittos on LG World Challenge Wheels and they rub the outside of the front fender. They are slowly wearing away the top of the plastic spoiler at the front of the wheel well.

I think mine might contact there slightly too. But several fronts over 2 years and 20 track days ... nothing worn out and no problems at speed and high G

If your allignment is on and you are running stock wheels then there has to be something going on with the duct itsself. My 285's on my 20"ADV1 wheels touch where yours are rubbing but only ever so slightly and only at full lock. I am never going more than .3mph so I dont even notice it.

bright1984

The tire only comes in contact with the duct at full lock. I'm not worried about track or autocross applications, but rather maneuvering in tight spaces, ie parking lots. It seems that if it continues to rub at full lock, eventually it will make a whole in the air duct, making it less effective.

Stock wheels here. Same tires. Slammed on stock botls..zero issues.... how often do u go to full lock anyways?

Dirty Howie

Are you seeing loss of duct material (a groove) or rubber and tire dressing being deposited in the duct.

Rubbin is racin.

bright1984

Every time I pull in/out of my garage.

bright1984

Not yet, as the tires were just put on last weekend.

Maybe this isn't a big deal and I shouldn't worry about it but figured I'd see what folks have to say.
