Big Brakes with a Twist

Big Brakes with a Twist
So...I have an SA with a streetported 13B that I upgraded with Respeed rack, coilovers and Illuminas a couple of years ago. I loved these upgrades eventough I had to tweak some of it for it to totally suit me. The car handles like a slot car and with springs that are soft enough for my wife to tolerate. I love it. I had avoided upgrading the brakes cause I was relunctant to loose my 4 x 110 wheels but I finally gave in and decided to upgrade.
The twist part is that I did not go with the normal turbo II setup. I really wanted to keep it as light as possible, use 4 x 114.3 pattern and get the best braking possible so I found KC Raceware that makes lightweight aluminum hubs that use rotors made by Coleman Racing. These parts are designed to be used with SE single pot calipers and I wanted 4-pot calipers and larger rotors so I got coleman racing to make larger rotors and got Mr. bwaits to help me out by designing caliper brackets (Thank you Mr Waits!!!!)

This was a little pricey, but it will give me the larger brakes I wanted and at the same time, and this is hugh to me, reduce my unsprung weight 5.5 pounds per wheel!!!!
Just waiting on new springs so I can bolt it all in.

Damn! 5.5 lbs! That's going to be a big deal at the end of the control arms. Let us know how the ride changes afterwards. Should be really nice. Illumina's are adjustable both ways, or just one??
I also pray at the alter of Mr. Colin Chapman. :-)

Yea, I hope 5.5 lbs makes a big difference. I also installed KC Raceware lightweight hats and rotors on the rear that is supposed to be over 4 lbs lighter. They also use rotors available from Coleman racing.

They are 10.8, which is the same as FC brakes and they will fit inside 15 inch wheels, but just barely, I started to try 11 inch rotors but they would have been so close that they may have interfered with stick on wheel weights. You could go really large with 16 inch wheels but I like the look of 15's, plus they are about two pounds lighter.

Test fit in the new wheel:
Thats a 15x7 +40 offset with a 205/50-15. The caliper to wheel clearance is only about 1/4 inch. I tried to get a pic of the gap without success.
A wheel with about a 35 offset would have been a little better but I could not find one that I could live with appearance wise.

I purchased the RE-Speed front and back BBK. I really like your approach. Maybe if Billy is willing, he can make or share his skills and maybe you could make a parts list for us?
I've been to the KC Raceware shop serevral times. I even have a neigbor that works for them once a week.

As far as the caliper bracket, as far as I am concerned the design belongs to Billy, he took an interest in my project and was nice enough to help me out, I would'nt want to put him to any additional trouble or inconvenience.

Yea, its two piece, and that is the only possible down side. If you ever need to change the wheel studs you have to unbolt it and press it apart. Given that would be a very rare occurance I dont consider it a negative. If you were racing every weekend and changing wheels often it may be more of a concern. Well worth the hugh weight reduction imho.
