Here’s our Wilwood/UUC passenger rear section installed. Compared to stock, each rear corner saved 2.5 lb, thanks mostly to the Wilwood DynaPro calipers.
Here’s a comparison between our new Wilwood pads (bottom) and stock (top). Our new pads feature Wilwood’s “medium friction” compound, which are suitable for a combination of street and racing performance, due to their low noise and dust ratings.
Our front Wilwood pad has 2.1 cubic inches of pad volume and 6.36 square inches of pad surface. Pad thickness is 4.9in and the peak temperature rating is 1100F. The company also sells pads that can withstand 1300F and beyond, for the extreme racer.
If you’re going to run a big brake kit without using the proper high-temp fluid then you’re missing the whole point to the advantage of a big brake setup. Like putting ST-rated tires on a Ferrari F40, it will only work if you never “floor” it. Fluid boil will quickly be your weakest link, sending the pedal to the floor (and your front bumper into a rear one) after repeated stops.
Wilwood’s EXP 600 Plus is a highly refined fluid blend developed for extreme performance under the high-heat situations of professional racing. It’s been tested to a whopping 626F dry boiling point and 417F wet, which far exceeds any DOT or SAE specification. The Motive Products bleeder makes this job easier for one individual to do, and it's sold through UUC as well.
Wilwood reports that this fluid not only resists aeration, but also compressibility, after hundreds of cycles. It’s the fluid that will leave a firm pedal feel with quick response lap after lap, and long after many other fluids have failed.
I must admit, with the car sporting black calipers, I thought that these brakes would go virtually unnoticed in public. But in just my commute yesterday, two people stopped me on two different occasions to ask about the brakes.
The stock-sized rear rotors fill the rear wheels nicely, thanks to the 18-in wheel diameter.
