Default Staging Lane issues

I decided to post my problem here instead of the S197 Tech forums because I know 100% of you guys go to the track...

I was At the track today and I had this annoying problem, when I rolled up to the staging lane, the car wouldn't stay put unless I pressed on the brake pedal, which caused me to foul out a LOT of times.

It just rolls very very slowly, but enough to make me break the beam before the green light comes on, which was very annoying. This is the first time it has happened to me, did not happen the past 3 times i've been to the track (the same one).

You guys know what could be? My car has the manual tranny.

Maybe the clutch cable needs to be adjusted? The idea behind that is that the clutch is still catching the flywheel/motor, which would make the car roll forward? It's a weird idea, though.

Did any other cars have this issue at that track?

nope, only me, and only this time. the past times I didn't have this problem, and the clutch idea seems logical, but I can't think on a way the clutch cable needing adjustment, don't S197's have hydraulic clutches?

they are hydraulic, not adjustable.

maybe a bad slave or something.


give the clutch fluid a good changing and bleeding and see how it goes

It does sound like a clutch that's not completely disengaging. Any hydraulic leaks? Does the clutch feel different than normal? Any noise? Also, if you have someone to help you, have them press on the clutch and watch the balancer at the front of the engine and see if it moves excessively. Also, you can pry the balancer back and forth with a prybar and some light pressure....you can check crank end thrust that way(if you lose a thrust bearing some of the clutch release motion goes to moving the crank instead of disengaging the clutch, but let's hope that's not it). It could also be a warped flywheel, disc or pressure plate, or a bad pressure plate diaphragm.

And yeah, bleeding the clutch certainly can't hurt. The fluid gets hot and beat up after a while and the system loses a bit of pressure from it.

well I did install a line lock the past week, would you think the brake system/break fluid be the culprit?

Unless you had to tap into the clutch hydraulics, it shouldn't matter.

No. No power should be getting to your wheels while the clutch is depressed, although with my car on jackstands and the car in nuetral, I have seen the wheels move which I found strange, although I could stop it with my hands and on pavement wouldn't move ( I drive a honda though). If it's actually able to move your car, I would think that something isn't letting go fully. You probably need something fixed/adjusted. Weak diaphram maybe?

That's just from the minimal internal transmission friction. Mine does the same thing. It's just BARELY enough to overcome the mass of the wheels etc and the axle bearing friction.

clutch feels just as the day I bought it, I'll try bleeding tomorrow.

well I guess my car is getting enough power to MOVE the car on a dead stop...something is really wrong here.
