4 piston 12.6 inch big brake kit. Using the newest design calipers from Wilwood, these calipers use a dust seal to increase caliper life and prevent piston damage from salt, sand, etc. Kit comes complete with the 4 piston calipers, 12.6 inch rotors, aluminum mounting hats, pads, adapter brackets, and braided steel front lines. MUST use 17 inch or larger wheels. Lower offset wheels will clear the calipers easier. 

Customer Questions


Will this calipers fit with a +12 offset


The clearance between a wheel and a brake caliper is dependant on the wheel design and specs. In general, a +12 offset is pretty low and it may be problematic. Unfortunately we cannot give a concrete answer.


How about the OEM 17 inches wheels from TSX, will these calipers fit or will it require to use spacers?


We would assume spacers would be required to use this brake kit with factory wheels from a TSX.

Q:Will i need to upgrade my brake master cylinder or any other brake system components to reliably run this kit?

No this kit is has calipers which are designed to be suitable replacements for the stock one without greatly impacting the pedal travel.

Q:Would it be possible to purchase the kit without the SS brake lines? I already have a set of SS lines on my car. Let me know, thanks!

If you mention in the order comments at checkout that you do not need the lines we will A) make sure your standard-fitment lines will be compatible with the calipers, and B) provide a refund if you do not need the new, supplied kits.

Q:Would 20mm spacers work on oem wheels for the tsx to fit these?

We don't have the spec on the needed spacer for clearance, but 20mm is rather large and should work.
