So I'd like to get the willwood BBK, but have now clue what the required offset will be to fit rims over them.

Anyone have this information or know where to look?

Thanks in advance.

 

Can you be more specific which Wilwood BBK you are interested in?

 

This is the information from the TCE Performance website. I plan on getting the 12.2 inch rotor, but that shouldn't impact the offset required for wheel fitment.

Here's a power house performer that fits 15" wheels! The Wilwood factory 11.75 kit comes with heavy duty rotors, DynaPro calipers with stainless steel pistons, BP-20 Pads and more. Rotor hats now fit for M14 studs. A great kit at a great price! If you desire a smaller kit for 15" street use TCE can supply the Plus 2 kit in a smaller size as well.

"Stock" offset is fine. It's not the offset that's the potential issue with any BBK, it's the spoke clearance. While clearance can be gained or lost with a change to the offset why take that route if you can keep the stock offset and just pick wheels that fit?

Clearance requirements can be found on the pdf click links on that same page.

 

Ok, so if the stock offset works, but the spoke clearance is the issue, how do you browse rims on-line and figure out what fits and what doesn't? The information on a site like Tirerack doesn't seem to be adequate to determine what fits. Or is it and I'm just missing something?

I've seen defferent templates on line that I could hold up to the rim, but if the rim is a bunch of electrons on my screen that doesn't do me much good.

Sorry for all the questions and confusion, but I really don't want to order a set of rims and have them not fit. That would be below average.

 

You have to consult the wheel supplier or discuss with others what wheels they are using and if they are or are not using spacers to fit them. Most are not with these particular kits.

Generally speaking....most aftermarket wheels marketed toward the track day user are designed to accommodate this need. You can also 'roughly' gauge the clearance by spoke design just looking at them and given that these kits are quite low profile you can eyeball clearance gains in the caliper area on many very easily compared to stock.

There are also a vast number of wheels shown in all the picture files of the various kits here. A call to Tirerack or other suppliers and they should have a pretty good idea of what is needed based upon the pdf profiles also because they can compare that to wheel info you cannot see.

 

FYI,

Tirerack will try to help you with the spoke clearance but my experience is that that cannot use the pdf profiles that easily. Alex from tirerack has been willing to help a lot particularly if you are interested in a particular wheel.

I know for the TCE plus 3 kit:
Enkei PF01 17x7 ET38 works w/o spacers
Mini R104 17x7 ET48 works with 5 MM spacers
Mini R110 17x7 ET48 does not fit
BBS RY 17x7 ET42 works with 12 MM spacers

 

Too add to that some.....

The stock MINI wheels are not known to be very BBK friendly. Only the R90 which looks like a BBS is really the one to offer much clearance. That being said however with the use of the new DP6 caliper there should be some good things for even a few stock 17s. (not the S-lite)

This caliper offers a very low profile as a result of using a thin pad and low body design. Granted this is not the first choice for hard track day use given its mass and pad thickness. But for an occasional day of fun (with proper compound) its still a capable package. And the low clearance works well with more wheels looking good too!
