If you
browse through our Essex blog, you'll see tons of owner feedback on the suitability of our systems for both road and track. Here are a couple examples of customer feedback after 4-5 years and 50,000 miles of combined road/track use:

Our CP9660/372mm brake kit weights vs. OEM M2 Blue and M2C Silver brakes:
Front brake caliper weight:
Blue M2= 8 lbs.
Silver M2C= 10.7 lbs.
AP Racing CP9660= 6.2 lbs. (+0.5 lbs.for CP9668)
Front brake disc weight
Blue M2 380x30mm= 24.2 lbs.
Silver M2C 400x36mm= 30.2 lbs.
AP Racing 372x34mm= 21.4 lbs.
To get the total off the nose of the car, you'd double the numbers above (I don't have the pad weights handy, but they factor into the total weight savings as well). On the front, our Competition Kits shave in the ballpark of 25 lbs. of unsprung weight vs. the big M2C setup, and about 10 lbs. vs. the OEM blue/base setup
Rear brake caliper weight:
Blue M2= 6.2 lbs.
Silver M2C= 8.0 lbs.
AP Racing CP9449= 4.95 lbs.
Rear brake disc weight
Blue M2 370x24mm= 20 lbs.
Silver M2C 380x28mm= 21.2 lbs.
AP Racing 365x30mm= 16.8 lbs.
On the rear our AP Racing Competition Kit saves about 12 unsprung lbs. vs. the larger M2C setup, and about 10 lbs. vs. the standard blue rear brakes.
Total unsprung weight savings with our Competition Kits at all four corners are close to 40 lbs. vs. the larger M2C system and 20 unsprung lbs. vs. the standard blue brakes. Our kits will fit many lightweight 18" wheel/tire packages. When you factor those savings in, you may be looking at 60 or more lbs. of unsprung weight savings. Huge bonus...you don't have to remove our entire caliper to remove pads like you do on the OEM M2C calipers.
You can
see the M2 discs above on a scale in this Essex Blog post.
Here are our AP Racing Pro5000R calipers next to the standard blue brakes...which in this case were turning green after only a couple visits to the track. Spaceship vs. biplane.
