Wilwood BBK question

Anyone running the new six piston kit on stock 18s? I'm thinking about using them for my aftermarket wheels, and I did the measurements with the diagram that they supply online but I'm still not positive. If someone is running them on stock 18s can you tell me how much clearance you have from the spoke to the caliper? I'm not worried about diameter I'm worried about the caliper being too far outward from the car and hitting the spokes of my wheel. My aftermarket wheels have about a half inch less space from spoke to caliper the the stock 18 inch ones. So if there is more than a half an inch clearance from the Wilwood kit then I'm in business.

I have a 2004 with Wilwoods on all 4 corners. At the time of the installation the car had factory wheels/tires. 6 piston fronts, 4 piston rears. slotted rotors, but not cross drilled.

No issues.

On that note.

The cross drilled rotors look cool. They look really cool, no doubt. On a street application it was emphasized to me with an exclamation that using them would result in problems, cracked disks...

I've been a machinist for a long time now, I'm no engineer, but I do work with them often. Cross drilled cast iron opens the door for fractures on a disk being subjected to massive amounts of torsional loading. Just something to consider.

Last: The only real issue I had was fitting up the rear calipers. The sheet metal dust shield was in the way and I ended up using a pneumatic nibbler and Roloc disk to remove it. -wasn't my best work, lol.

Good luck.

Yep. I used a cheaper set of cross-drilled & slotted rotors (PowerStop i believe) on the goat a long time ago. After about 6 months of DD, they were warped and had spider cracks around almost every hole. I'm lucky they didn't just break in half.

On a heavy car like this I agree, stay away from cross drilled for DD. Although, I haven't heard anyone mention this about the higher quality DBA cross drilled rotors...

Sorry OP, i know this has nothing to do with what your asking, just thought I'd add on to what Longrifles said.

Thanks buddy!
if you could just measure from the spoke to the caliper.
On another note, how do you like them?

Thanks guys. Yeah, i never intended on the cross-drilled ones. I've had bad experiences also, even with my factory Porsche ones!
I intend on just getting the slotted ones.

Anyone needs some polymatrix H pads for this setup let me know. I have a killer deal on a set. By far the best pad for this setup...
