Clutch Stop ???

[nando]

I've had problems using clutch stops.

After a hot day at the track and running the car for 20-30 minutes at a time, the clutch engagement point started to change, going further towards the floor. This resulted in progressively harder shifting, and then some trans grinding. I adjusted the clutch stop which fixed the problem, but the next morning, the engagement moved back to where it was before tracking the car, giving me about an extra inch of travel after disengagement. This was all with

I ended up just throwing the clutch stop in the toolbox and driving without it. I also race other cars that have the clutch button to start the car (no clutch stops), and I find that it takes less time to re-familiarize with the other car's clutch engagements/pressures without a clutch stop. Having no clutch stop also helps modulate when problems in the clutch system arise, like for instance if your slave/master starts to act up during a race due to low brake fluid level during a turn or something, sometimes stomping on it all the way to the floor and letting it spring back up a few times temporarily fixes the problem. If you had a clutch stop, you wouldn't be able to do that.

or you could fix your clutch?

I have a stop in one out of the two and I think I prefer it without...

I went the Home Depot route for mine. Works like a charm.

If you unscrew the plastic cap in the floor you can take it to Lowe's or Home Depot and figure out the thread size.

So we adjust by feel not a precise measurement?

Well depending on the condition of your components (master/slave cylinder, type of fluid, air in system etc) not everyone's clutch disengages at the same point, so individual adjustment is needed. Also, people have different preferences on how much pedal travel they want, so it's best to experiment for yourself.

EA8 You infidel you stole my thread, may a thousand camels spit on you....

jk

me likey ... so basically less time spent pushing in the clutch :D

any drawbacks? more wear on the clutch maybe??

sorry Aerton if it seems i am taking over your thread. Cheers

I am for sure adding this to my to do list for my ix:p

"Late model vehicles have a dual position, solid state clutch switch which requires the clutch pedal to be depressed nearly completely to the floor in order to start the vehicle. For these vehicles, the clutch stop cannot be adjusted to the limits of the clutch pedal engagement unless the clutch switch is modified. Modifications to the clutch switch are required to allow for both vehicle start and cruise control functions to be retained"


any comments on this statement that i found on Rogue engineering?? Is it really necessary to perform the clutch switch mod??

cheers

No e30s are like this. They didn't start doing that until e36s as far as I know.

I have an 89 325is. I didn't change it for mine.

i think when they say late model they dont mean late model e30

No, just adjust it so that the clutch is fully disengaged when the petal hits the stop. No drilling is requited either. All e30's have a "nut-sert" type of thing in the floor board. Just remove the stock little rubber part, thread in a bold with a stop nut, and add a rubber stop to the top. Adjust, and enjoy.

what is a clutch stop??

noob in da house

When you press down the clutch, it completely disengages and the pedal then travels about 1.5" further to the floor. The clutch stop stops the pedal right after the point where it disengages, so you can just stomp on it and not waste time.
