Pretty interesting stuff! Looks at some of the brake pad details, manufacturing process, and testing methods. And the 4-piston, 4-pad caliper... pretty trick.

 

My engineer/mechanic has wanted me to switch from Hawk to Performance Friction. He has liked the 83 compound for years. After my passed weekend with Hawk I am ready to switch. They sent me rear DTS 60 brake pads for my Evo 8 that I tried installing at the track. The backing plates looked identical but the pads are now much thicker and would not fit on the inside. I tried installing only the new pad on the outside and picked the best worn pad for the inside. I drove the car to false grid right before a race and found when I applied brakes the new pads backing plates tore all my outer hardware on the 2 piece rotor hat. This is unacceptable. Think twice before you buy Hawk pads for your Evo. I purchased them from Porterfield, who should know better. I may be switching to Performance Friction after resurfacing the rotors for a pad material change.

 

I changed to the 01 compound, haven't ever regretted it! Not a street pad by any means tho...
