No offense, but I don't think I'd ever put a Willwood BBK on my vehicle. Poor caliper design and lots of flex. And putting a 6 piston caliper on a stock disc defeats the purpose of a BBK...which is to be a better HEAT SINK. Improved stopping distance is mostly from better pads, good tires, and brakes which are biased correctly.

 

Oooooooooo pretty!!! :D tell us how they work!!! After break in of course

 

please explain what you are basing this info off of? I have spoken to many people that run wilwoods, and I have never heard of a single problem. It sounds like you have specific information, on the design and how it flexs and the flaws. Please provide some examples, sounds like you would be able to do this..

 

His info is not totally incorrect, there are various levels of caliper value, design and fit. And his comment on the larger rotor has merit as well. But what's missing in this basic statement is that this same caliper in the set up as it's being used now can be fit later with the newer JCW rotors (320mm?) or with a set of larger yet 13" rotors....both of which offer the greater mass. This set up now is simply a good starting point.

It's sole purpose in life was to offer the market a "caliper kit" for the oe (or other) size rotor. And one that fits behind nearly every wheel. Many of the other brakes being mentioned are certainly equal to or perhaps better. But having to purchase $2500 worth of wheels and tires just to have them isn't for everyone.

 

Hmm do u think the 6pot willwood would work with stoptech's two piece rotors??

 

With the right bracket and the proper caliper yes. The ones I use are intended for the narrower rotor. We also have a 1.10 width application which would fit. But I'd have to ask; why? Certainly nothing wrong with the ST calipers.

 

Im waiting for 2pc floating rotors to come out for the R56 JCW Brembos.

Anyone find out if the lines on the JCW Brembos are the same as a stock MCS?

 

I want your old calipers and rotors!

 

conveniently... i was talking to people about getting some kinda petition for two piece rotor replacements for the stock and JCW brake kit....

 

Hi guys!

I'm in the market for a set of JCW R56 brakes. As I understood in the package there are rotors, calipers, discs, discpads and breakwear sensors. As I intend to install the set on a R53 (2003) i would like to know what has to be purchased extra beside the stainless steel brake lines.

Thanks!

 

Nothing aside from fluid and make sure that you buy the R56 lines because the input for the brake fluid is in a diffrent location to suit the new car as opposed to our "old" ones.

 

No he'd also need a lug conversion kit cuz of the change from M12 to M14... U don't want the brakes to be loose on ur r53

 

the hubcentric rings should keep that from being an issue but i could be wrong.
Good point there though...

 

I confess that I'm not seeing the real need for the two piece rotorse now or on the older car. You're speaking of a cost of about $700 for what you're after, you do understand that? Cost aside the benefits will be minimal. You may argue a true directional casting and for hard track use and speeds about 80mph the increase in airflow may be nice, but the rotor itself will not be any "beefier" and most likely less mass than you have now.

I speculate that the air gap in the stock rotor is quite narrow. To make the total width fit the JCW caliper the casting to work from for the floater will be cut down to that final size. Thus netting a wide air gap and narrow rotor cheek.

There are a few options still and I'm certain it could be done. The weight savings would be nice but the final function won't have a huge impact on how the brakes work as the remain the same size.

 

strike true... motorphiles probably would appreciate the bling factor tho... not to mention... as with any bbk 2-piece rotor... only the origional cost is most because you're payin for the rotor and the hat... after that you just pay for the replacement rotors... unless there's something i'm missing...

 

Can the r56 JCW kit fit under 16" rota slipstreams, or 17" slites?
