OK there CR owners. We need your help and in turn I beleive that we can help you!

For those of you that know me, you know I love to tinker with brake setups and have come up with a few tools to help work out the problems. When I bought my car, I had to mark it on my calendar so I could plan ahead to stop. NO MORE. It now stops on a dime and returns change! No exotic parts, no dusty rotor wearing pads, just basic off the shelf stuff. If I can help CRII be the same way it would be very satisfying.

Here is where you come in. Following is the basic CR setup that I am working from. For those of you with drums, sorry! Please verify these numbers:

wheel base, 94.5
weight with driver and half a tank 2600
weight dist 50/50
front and rear disc diameter 11"
peddle ratio (the new one) 6 to 1 (if your is different, please give layout and measurements)
front and rear calipers single piston (talking per side so sliders and fixed are the same deal, well basically!) 2.5" diameter piston
master cylinder front and rear bore 1.125"
Pad CF .4
booster diameter 7", diaphram please!
wilwood proportioning valve (dial or lever type?)

Any of this information you can confirm is a BIG help.

Couple of questions. With the proportioning valve full on and full off, what is the difference? For those of you that can actually lock the brakes, with the above setup, which lock first? Are you noticing that either the front or rear pads go away first? Any other observations you care to share?

Any one have a G-meter and can give me actual data?

So, please, help us all out! I KNOW that Don is committed to making CR the best product he can so this is a 'win-win' type situation.

Thanks
Rick
