Question about your rear wheel setup with OZ. Is it the Leggera HLT et50 19x11"? Tirerack is telling me that there are brake caliper clearance issues for the gt4 but i find it hard to believe since you are running them...

To run the 11" wheel you need to change the end links, and possibly run a small spacer depending on alignment setup to make them work.

I found the brake caliper "interference" on the front calipers using 19" OZ. It wasn't metal to metal but lack of sufficient clearance. I ran the 19 x 10 on the rear without issues but did have Tarett Toe Links. Sold the OZ and replaced them with CCW. No issues with the CCW but the price more than doubles.

brad@tirerack.com

The front OZ's don't hit the calipers.

Wheel weights will have to placed on the inner edge of the wheel to prevent the calipers from knocking them off. There is also the possibility that rocks could get between the caliper and wheel, scoring them. It's a great wheel for the money, but it is very tight.

I thought I remember reading that Joe had an issue with the rear brake line poss rubbing ?
I think it was corrected with a little elbow grease. i.e. bending the line out of the way ??
Let Joe comment ....

I had a rear brake line issue with rubbing and a set of Spiegler lines corrected the issue.

Here is what I recall:

Front wheels clear the calipers, but the wheel weights need to placed away from the calipers. Also, the front brake ducts need to be trimmed or they will hit the wheel weights.

The rear wheels require aftermarket toe links or spacers. Not all aftermarket toe links will work. I know that the tpc ones will not work. Also, one of the electrical lines that control the parking brakes can rub on the wheel, so it needs to be bent over.

Joe speaks the truth. Coincidentally I took my OZ wheels for a tire swap and they mounted weights in the barrels a little too close to the caliper. If the car is jacked up without any load, it may clear fine and you think you're ok. I got black flagged on the first lap and the marshal says "we hear a rotational tick tick tick coming from your car." There's nothing like taking an razor blade to your $100k car to shave a little off the brake duct. All good and I went back out to have a blast!

Had the same problem (OEM 20" wheels) but you just need to play with the line a bit and bend a little the metal tab....so far it's good, no more rubbing problems.

Is there a common level of camber at which the OEM tie rods run out of threads? Perhaps that varies by car, but I'm only planning to run -2.5 degrees right now, so wondering if I need the front tie rods.

Above -3 deg.
