I was on street tires. It was a SCCA PDX and I was using it for practice for the redline time attack next week on the same course.

Watched it the whole way through. Loved it. Thanks for sharing.
The faggot in the elise was obviously not too pleased with the fact that you passed him.


A couple of questions, what tires were you on, and what is your brake setup like?

You need a bucket seat like whoah.

The tires are 255/45/17 Kumo XSs. They are extremely grippy for street tires and were cheap compared to like tires. The direzza star specs are supposed to be almost as good in dry and better wet but were more expensive. The advans and Bridgestone RE11s are way more expensive.

Yeah some seats would be nice. I'm on a budget and seat time is more important to me at the moment. Maybe over the winter I'll invest.

Brakes -
Front
Calipers - Q45
Pads - Carbotech XP12s

Rear
Calipers - remanned s14
Rotors - 2003 altima (over 1" bigger in diameter) had to use the caliper bracket from a 1986 300zx to space out right.
Pads - Axxiss Ultimates

Stainless steel lines all the way around and Valvoline synthetic Dot 4/5 Brake fluid.

The rear trick I did really balanced out the front Q45 setup and was pretty cheap. Before that it was way to front biased and I'd lock the fronts all the time.

My setup was one of the lowest cost DIY type of ways to go about it, but there are many other options. You could run the z32 setup all the way around. I hear that works well but you may need a bigger master cylinder and the parking brake is tricky. Others with the Q45 or Z32 setup in the front use an adjustable proportioning valve for the rears to get the balance right.

Here is a write up on the setup I have if you want more info. Not discovered by me, I borrowed from our great online community.

Thanks, I was braking way too early but it was my first road course event of the season so it takes some time to get comfortable enough to really drive at the limit.

The mods are SR20DET/ 550 cc injectors/ z32 MAF/ Freddy intake manifold & oil pan. Greddy Type S boost controller running at 15 psi/ 3" exhaust but with CAT / S15 LSD and street tires.

Suspension is mainly buddy club RSDs, replaced traction rods and rear toe arms. Still need to replace most of the bushings as they are worn out stock rubber crap with 146,000 miles.

Brakes I went over earlier but Q45 front calipers 5 lug conversion and 2003 altima rear rotor trick. Also Carbotech XP12 pads in front.

I had a ride-along in this car last year at WMHM9 and it feels great.

S15 T28 on 15psi is a nice predictable setup.

There was a grey turbo miata that crashed at the redline time attack on sunday. That was pretty crazy. He slid down most of the front straight. It was the fastest, longest slide I have ever seen.

Have you ever raced a guy with a white honda, black wheels, an intake and some other stuff by chance? I know a guy who once knew a guy who had one and I watched him pump gas in it once, and even though It doesnt matter Im gonna ask anyway because.................. IM A FAGGOT.
