Couple days ago, I was at the "home" track for the fifth time this summer.
here's what I have stock 15/16 rims with Kumho MX, all looks like having pretty good tread height whereas the right rear slightly worn with the shoulders being a little bald... I've been told on the dry track, I still have a lot of miles ahead of me before I "need" to buy for new ones.
I had swapped the front pads to the carbotech pather+, however kept the rears axxis (my street set up), the set up was always brilliant... even when I did the bed-in the previous night. On track, the car felt very slippery, seems like the back end always pushing the car at the high speed braking, (ABS kicking in while the car doesn't really feel stopping at all).
I found out that my tire pressure is a little high the first session, and I was carrying my buddy who is around 190 lbs. At the last session, I corrected the tire pressure back to 32 / 35 hot. and decided to go solo, this time the car feel brilliant again. but the feeling (though much better now)of running out of pads (which, in reality both pads still have a lot in it) still there at the high speed braking (140 to 65-70 in 3 cones.)
I was suspecting since I used the axxis pads at the rear end both on/off track, while I only put on the panther pads just for the track use. Maybe the rear pads are thinner thus less stopping power; but once I thought thru how the brakes work, it should not be any problem. One thing though, I was doing my spraying and sponge 5 mins car wash before i hit the track, and I did spray water directly to the wheels and rotors/calipers, I lot of brake dust run out to the pavement. Does this action basically destroying all the uniformed deposit I put on at the bed-in??
by the way, my brake was beded in two nights before, and it got more than 30 hours sitting in my garage to 'cool down'....
anyway, except for a little frustration at the straightaway braking, I was doing quite happy with the car. Except there was the time a S4 driver (I believed it got engine mod) refused letting me by for 5-6 laps. It was a little frustrating, I could brake deeper, and carry more speed going into any corner than him, but I was force to brake early and not "pushing" him. His car highest speed at the end of the straightaway is at least 20mphs slower than what I could do. However since I decided not to sticking my front bumper into his, everytime he was walking away as soon as he past the apex cone, I tried and tried, everytime I caught up with him, it was either blocked by some other slower cars or closed to the end of the passing zone and of course, he would not back up and give me the pointer.
That brought me to the question that if I needed better tires and/or wider tires (if there's any other size fit the stock rims.?) I am quite confident I was riding the edge of the tires traction in couple tight corners, and the car usually exhibit a little over steer in a very smooth fashion and I was being able to correcting it with no drama... but just seeing that 3800lbs car keep walking away from me at the exit of the corner made me
