My circuit 93 trac has an issue with killing the front brakes at the track. After a half an hour at full speed the front brake pads are metal to metal with the rotor. Every time I go I have to bring brake pads with me and even them Im running around looking for more front brake pads at the local shops. In relation to my 91 mr2 I have been bringing to the track the brakes wear 1600 times faster on the st185. This is terrible in relationship to my circuit 5vz swapped mr2 (stripped, non abs) that only weighs 250 pounds less then the st185. With the mr2 I can get about 8 hours full out before the front brakes are metal to metal and more then 16 hours out of the rear brakes. It has reman calipers & aftermarket stock replacement brakes all the way around with 215k on the suspension!
I assume its from significantly more weight being distributed on the front of the car and the ABS still being installed on the car. I plan on eliminating the ABS in the next couple of months with proportioning valves so I can increase the rear brake pressure given the suspension setup in the car and how little work they do right now (nothing really). Its possible the factory setup is just getting too hot & isnt up to the task. I was hoping some people that track their car & have had the same issue will chip in.
Suspension & brake setup:
Weight distribution is like 65 something percent on the front wheels
Weight of car: 2960
Factory ABS still installed (not working)
New OEM calipers all the way around
Ceramic stock replacement brake pads & rotors
SS brake hoses all around
BC racing custom spec coilovers ( approx 3 x factory spring rates ) lowered 2 inches according to factory specs
Eliminated sway bars with stiffer rates
Volk 17x8 with 215/45r17 tires (soon to be updated)
