[Supras] stock brake rotors

[Khalid Almufti]

Thanks for your advice Ken, and I will bite the bullet and buy front and rear pads.  For my past events I have been using Axxis pads and these worked ok, but due to reasons similar to yours, I keep them on and kept driving daily!  That was a mistake, and the end result was the rotors got eaten up and I could feel the effect in reduced braking performance.  I measured the rotors, and I am at 0.840" thikness, which is above the limit by 0.013".  Since those where relatively new rotors, I am disappointed to the extent that I am now switching to another pad (I was advised to remove the pads, but ignored it).  I actually don't think the Axxis pad where bad, it's just that they do eat up rotors and produce tons of dust that does stick to the wheels ("painted" my 5zgens black).  So now, I am sort of starting from scratch on my braking system with new, different type, pads and rotors, stock given the feedback from Jeff and Brian.  The car has hard brake line so
 I think I should have a decent setup for track events.

Regarding the ST-41/42 pads, be sure to GET THE REARS TOO! I know it is a lot of money, but there is no comparison to just doing the ST-41’s in the front. With the 41’s up front and 42’s in the rear, our big ole’ heavy MKIII’s actually feel light and agile under braking. The brake pedal will seem very responsive with the slightest application of the brakes and the car will nose over hard with moderate pedal pressure. The rear of the car almost twitches like a mild hand brake feel when braking hard on the track. 
How do I know the ST-42’s in the rear are sooooo important. Well, I had a few NASA events where I only had time to change the rears out for my daily driving for the following week. So I put my Porterfield R4S’s in the back and left the ST-41’s up front. At the first stop sign by my house, I thought there was something wrong with the brakes. I had gotten used to the responsiveness of the combo and was SPOILED. Actually the week after every event is rough for me, because each time I don’t want to take the track pads off. One of these times, I will bite the bullet and leave the Raybestos pads on permanent. Daily driving and all! The car is so much SAFER with these pads on….even totally cold!
