Center of Gravity / Roll Center (re: Brakes)

[Daytona Dan]

I am working with Stop Tech to come up with their opinion of best front caliper piston sizes for my car. Starting from scratch is like a Rubik's cube but based on Tilton's initial advice I went with a 6.2:1 pedal set with dual masters (13/16 rear / 15/16 front) and plan to do 355mm rotors to go along with the Wilwood Dynalites that I have in the rear. What we think will be best is all mapped out in the attached spreadsheet that my trackday compadre Craig put together. Sorry I was not able to upload in Excel but I can email as necessary for anyone interested.

The current question from Stop Tech is what is the Center of Gravity for the car? I am also interested to know what's the Roll Center for the car? Each of the 3 configurations of the Coupe will of course vary based on all of the basic choices and crazy cool mods that everyone is doing these days, but what do you guys think is the ballpark CG and RC for a my Pin-Drive Width IRS Coupe?

Hey Dan,

Stoptech put together a custom trophy big brake kit for my GTM. They ended up with 14 inch full floating rotors all around with 6 piston front and 4 pison rear accounting for tire size and compound as well as weight balance / roll center and the master cylinder sizes as they come with the kit.

I was very happy with what they came up with. I hope to have it out on the track in the next few months to try it out. I would love to see what they suggest for the Coupe.

Its the next car on my list to build.
