"The VAC kit is not just a 'big brake kit' it's a better brake kit"

VAC Big Brake Kits have been designed and tested for track and street use including all out competition vehicles. Using the ultra consistent and light weight Wilwood calipers maintains minimum weight and exceptional brake bias.
Our replacement rotors are super affordable and always in-stock. Plus, nearly every manufacturer makes pads for the Wilwood Dynapro calipers, which makes it easy to get the pad compound of your choice.

Why is this a "Better" Big Brake kit? Adding larger calipers means more unsprung weight and sometimes higher offset wheels, limiting your fitment options.
Don't fool yourself in to thinking bigger and heavier calipers than our Wilwood Dynapro's stop the car faster, it's simply not true. These compact units are big performers; with 4 pistons the bodies are fully CNC machined from billet with internal fluid ports that eliminate external fluid tubes. Each caliper is equipped with four corner bleeds to accommodate mounting in all positions. The bridges are equipped with stainless steel anti-rattle wear plates. These plates reduce bridge wear and provide smooth, rattle free operation of the pads. A center bridge bolt adds overall caliper strength and positive retention of the top loaded pads. This offers the most linear clamping force for either performance street pads or full track pads.
Our kits affix to the wheel spindles with our CNC'ed brackets and use ARP hardware so they can be serviced and are mounted as rigidly as possible.

When we couldn't find kits we liked off the shelf, we decided to make them our self and offer the highest quality and best customer support in the industry...

• This kit's ultra light weight allows your wheels to track irregularity's in the road better than any other. This keeps your tires in contact to the pavement and increases traction; therefore turning and braking potential are dramatically increased.
  
  We always test the products we sell: we chose Wilwood because of their proven performance on our own street and race vehicles (and those test have been grueling, everything from daily driving thousands of miles in 0 degree ice cold weather too 100+ degree ambient temps).
  We have been making our own kits for years with tremendous results and lots of feedback. Every detail is scrutinized, down to the latest addition of ARP hardware.
