If I was to get a BBK for the front (Touring model), would it be possible to simply remove the stock rear rotor / caliper combo and replace it with the stock front combo.
This would allow a bigger rotor and pad combination to achieve higher temperatures in the rear when driving on the track.
Or is it a case that the front brake system just won't fit in the rear?

 

I don't think the brackets will fit the same pattern and the bolts are different sizes, also the BBK's are designed with the rear brakes in mind so if yo change that you will change your braking bias. Tempting but probably not a good idea even if you could do it.

 

Yeah, I didn't think it would work as everyone would have done it to save money on a rear BBK if it would work (unless of course you wanted a BBK on all fours for the looks).
