Asking Price:

USD 95.00

Shipping Costs Included

Item Interest

I am selling v1 of Westersund's Brake Cooling Kit. This is for a pair of FRONT backing plats only. It does not include the fog inlet scoops as I was looking to draw air from a different source. Also, his kit comes with 3.0" diameter funnels as standard but I had requested for 2.5" for easier plumbing/routing.

Only reason I am selling is because I upgraded to his latest design which provides more coverage. However, if you snip only what you need to from your OE plate, you will retain nearly same coverage with this. I made the mistake of entirely removing my original backing plate hence why I wanted to upgrade to his latest.
This is a quality kit specific to Z4 M; fitment is spot on and 100% functional for those looking to keep braking temps down.

Standard backing plate & funnel retails for $135 shipped. My asking price is $95 shipped to anywhere in 48 states if PayPal as gift (else add 3%).

First picture above was when brand new. Second and third are obviously with the kit installed so it’s picked up few nicks. Kit is otherwise like new.
