Yep I can help you a lot! Call TOBIN at KORE3

Don't take "advice" from a bunch of DB's on a forum... talk to a real expert about what you have and what you are going to need to "fix" it.
My initial advice is that you're running a "hot rod" brake (I have larger calipers and rotors than that on my 37 Ford!) on a car you're trying to "track" --- but even then --- you should be able to lock the brakes up on the street. Period. If you can't then you have something out of whack - which you already seem to know.
