StopTech BBKs: Will they fit behind OEM wheels?

FlyingLow78 · 10-18-2017, 12:43 AM

I'm looking at picking up a set of StopTech BBKs front & rear, but I'm concerned it may render at least one set of wheels obsolete. I've got 18" BBS winter wheels, 19" 437Ms, 19" OZ track wheels, and 19" BBS track wheels, and I'm pretty sure at least the winter set won't fit anymore.

Anyone here have experience on what definitely will fit and definitely won't?

Turner Motorsports has a handy measurement template, but I'm not at home to check my wheels for a few more weeks.

Looks like they'll fit behind 18" wheels, since they're the same overall diameter rotors as OEM (just thicker and with broader calipers/pads). Nineteen-inch wheels should be no problem.

What size rotors?

I have them on my oem 19s with no clearance issues and no spacers.

That's not always sound advice. Usually the clearance issue is the larger caliper, not the rotors.

I can attest the 19s fit. I have not tried the 18s.

Ideal BBK rotor size to accommodate most 18" wheels for track are 365/345 mm.

Stoptech 380 can work under a lot of 18" wheels but only after checking it with a fitment template that you can be 100% certain. Shoot us a PM or email and we will get you a fitment template.

For 18" BBS wheel that had my snow tires, the wheels needed spacers because the spoke would hit the caliper. I don't know the exact measurement because the brakes aren't mounted yet.

They fit under my 18" Apex EC7's
