What size rim and BS is required to run a 275/60/15 Drag Radial on a Fox with factory rear disc brakes. I am looking at a 15x8, but want the wheel tucked under enough to sit right with the car being lowered.

Just curious as to what you guys are running, and pics would be a plus!

15x8 with a 5.5bs will fit perfect.

15" wheels clear factory rear disk brakes no problem. They will even fit the larger factory Cobra brakes with a little work from a 4" grinder. [Wink]


Here is a pic of a customers car with 15x8's with 5.5 BS

Yellow 94GT,

What size tire is that? The car I am working on is an SVO... what grinding is required? The caliper?

That Rim sure looks Deep... Are you sure it isn't a 15x10 w/6.5 Backspacing...

The grinding required on the Cobra brakes is on the banjo bolt and square area if the brake line where it mounts to the caliper.

The tire in the pic is a MT ET Street Radial, 275/50/15 on a 15x8 inch wheel, 5.5 BS. [burnout]

I'm runnin' 10's on the Cobra now. No issues other than removing the quad shock.

Posted by JohnB (Member # 969) on :
 
Yes, it's the same as a SVO. 15x10's, 6.5 BS, 26x10.5's...
