Re: I asked: Track it or sell it, you all said track it! Finally ready to run!
Curt,
Interesting story on the gearing. The Zr-1 tach is notorious for being inaccurate. C'est la vie...
I'm a Haibeck fan. Pretty much everything I've done is in consult with Marc.
As for the brakes, it was my thought that after using softer compound pads that leave a mess on the wheels and brakes that I'd just go to a bigger caliper and a less aggressive pad to get the same results. When I ran a Spec 944 that didn't allow brake mods except braided lines and different pads the corrosion on the piston rubber was a real issue that we had to keep up with all the time. If my ZR-1 was track only, I'd probably just go with softer compound pads, but for a street car, I didn't want the dust everywhere and the corrosive remains on the rubber and urethane.
Battery movement was more a matter of choice, than not. I wanted the space where the battery was for the battery disconnect switch with a means to pull a cable without opening the hood. I've seen a few too many track incidences (electrical, not banging fenders) that warrant that comfort. I'm setting it up so the cable can be tucked away when not at the track. Going for a lighter battery does the same trick, probably better because you don't have the weight of long cables. In my track 911 the battery is forward of the left front wheel so with that weight and the driver weight on the same side, it was a corner balance nightmare. I replaced it with a 600 CCA AGM motorcycle battery and all is fine. Not something I can do on the ZR-1 because of all the electronics. On the Porsche all the battery does it prime the fuel, power to the computer, and start the engine and then the alternator takes over once running.
