I tried searching but couldn't come up with anything. Anyone knows?

 

Some will, some won't. I think it mainly depends on what kit you want.

 

It depends on the dimensions of the caliper and rotor.

 

What BBK!? 4-pot? 6-pot? StopTech? Brembos? Wilwood?

You have to be more specific if you want specific answers.

 

Always happy to help. If you have other questions please don't hesitate to waste my time.

 

my Baer 6s calipers with 14'' rotors clears.

 

An 18" weel will fit any 13-14" kit with regard to its diameter. The issue is the size of the caliper body relative to the spokes of the wheel. Some calipers are wider than others and pose a problem for spoke to caliper clearance. Sometimes the same caliper may clear on a 13" rotor but not a 14" simply due to where the spoke curves or how rapidly it curves.

Most kits offer some form of templates for measuring this. It's important that you check this before you bolt up your new purchase so not to damage either the wheel or caliper. If a wheel spacer is needed to clear the caliper I'd suggest a "washer test" where a stack of 1/2" washers can be fit to each stud and then added or removed to gauge the required wheel spacer thickness while netting a clearance of about 1/8" between the caliper and spoke for a required air gap.

FWIW, the Wilwood factory kits and their BSL6r do offer one of the best clearance packages of all the BBKs on the market. Minimal body overhang with this caliper will clear nearly any wheel while retaining the cherished 1.25" thick rotors for good thermal mass. Be happy to quote you some pricing options if and when you're ready.

 

I apologize for not responding to this thread and also for not stating what BBK. I wanted to reply but when I was looking for the thread, I couldnt find it so I thought one of the mods deleted it.

Anyways, I was refering to a OEM Brembo BBK and a Rotora 14" Rotors 6/4 BBK. I wanted to see if I had the option to return my Z back to stock with the OEM 06+ 18" instead of the track rims. Also, if I did sell my current rims, would I be able to use 06+ 18" to roll on temporarily.
