17x9 +49 clear BBK?

Brian,

Great. Thanks for the info.

Out of curiosity, what is the thickness of the spacer that comes with the 6 piston Wilwood kit, and would it require longer studs at all?

Thin little 3mm spacer that does not require longer studs.

The regular 12.88 inch will easily fit most 17x9 thanks to very narrow six piston caliper on this kit.

Just to make sure, will the 12.88 kit clear the 17x9+45 RPF1 without the spacer? I can't run even the 3-mm spacer with 255 tires.

Thanks.

Nope..

This Narrow 6 piston is about as narrow as multi-piston calipers get but the Enkei 17x9 RPF1 45mm wheel still needs 3mm spacer to fit with this kit.

I also checked our other problem child, the 45mm RPF1 18x9.5 and it clears by about 3mm....making it our only brake kit that will fit without spacers with that wheel.

I'll order a set of Weds TC105N 17x9 +49mm wheels shortly. It will take a while for them to deliver, but I'll report once I try the Wilwood 12.8" BBK without spacers.

Should easily clear..

Thanks X25. Realize when I started this thread the 6-piston option didn't exist: I was asking if the WEDS would clear the existing BBK at the time (larger, heavier kit). Since then the 6-piston BBK came out andd since it clears stock 17x7 wheels there should be no issue with 17x9 wheels like Brian says.
