Hmm....Remember one of my ricer excuses, sticking brake caliper??

Yesterday I drove around town for maybe 10 mins and came home. I could smell the brakes burning and when I put my hand on the wheel (pass. front) I almost lost some fingerprints. Way to hot to touch for more than a second, and this was the spokes on GST wheels...

I jacked it up and took the caliper off, pumped the brakes a few times to get the piston extended. There was a light coat of surface rust all around it. So I took some PB blaster and 1000 grit sand paper and removed the rust/lubed it up. Worked the piston in and out a few more times and put it back together. I must say, now the car feels like a totally different car. I guess it had been so long since I drove it every day I forgot what it felt like to actually glide in neutral. I need half the throttle to stay at a constant speed, and I noticed the car wanted to roll when I let off the brakes, as opposed to before where it wouldnt, and it took some force to get it moving.

So for my next track day, hopefully, next week, Im going to try some things:
First off, not have a sticking brake caliper (how much could I have lost from that?)
Shifting maybe around 72 73 from 1-2, and 7k 2-3.
Different launching techniques. Ill try a traffic light launch and a slip n dump launch, see what yields better results.
Also, I wont be using the RS wheels. Ill be running my GST wheels with 205/55/16s. Ill try full tire pressure first, and lower it if needed.
Im shooting for at least a 90 mph trap.
