I will admit my brakes are not ideal. I originally intended to use the Forged Narrow Dynalite 4 calipers with the focus svt rotors on the rear of the vehicle, but didn't take into account the rotor hat not fitting over the hub. I was then going to use 6 pot calipers up front with focus RS MK1 rotors. I figured I could machine the rear hubs to fit inside the focus rotors but I was also worried about being able to fit the RS 324mm rotor and 6pots under a 16inch wheel. Time was running out and so was money so I threw the 4 pots on the front and I had the focus calipers laying around so put those on the rear. I still plan on changing them but they actually work pretty good for what I need right now. The front pistons are 35mm(1.38in.). I have an adjustable proportioning valve for the rears with it all the way open and don't experience lockup. I have BP-30 brake pads on front and OE organic pads for rear. The more aggressive pads combined with a larger diameter rotor keep the biasing very manageable. Also to take into consideration, just because a brake pad has more surface area doesn't give it more bite. The clamping force is spread out more on a larger surface area pad and is reduced when compared to smaller surface area pad.
I am putting together an LSD unit this week and will see how the car does with that. After that it's hood extractors and some body work. Over the winter I'll get the focus RS rotors and see if I can fit them under the wheels I have.

Thanks, a nother question for you....
Is there room to go pretty low with this setup on a xr4ti?
Also do you happen to have any other pics of your rear upper shock mount adapter?
Thanks again Ryan

Here is a website that sells them, I bought them off eBay.

Keep in mind I had to modify the extenders to fit inside the shock tower. Overall I do not recommend going this route, I would use a proper length shock.

The front can go as low as you want, the rear I have adjusted all the way down and would like it to be lower. The results will vary for different cars. My car is completely gutted and has an engine that weighs less than factory.

I'll probably just fab something up for the rear upper shock mount. I wonder what the recommended shock lenght should be a ride height.?
I plan on still running my 650lb 9.5inch tall camaro spring in the rear with the solowerks rear shock.

650lbs at 9.5" will sit higher than stock. Even if you remove the spring isolator. Been there, done that with 700s.

Well I might have to use the solowerks springs or chop off a little bit at a time of the camaro springs till desired ride height is achieved. I haven't pulled the car out yet for the summer and for some reason I thought when you install camero springs it would lower in from stock ride height.
