I would break any new clutch before any hard driving is done. 500 is the norm.

thanks for the reply. The problem is, with this clutch, it is very unforgiving. Any other clutch I've had, driving normally has never been a problem. This clutch has got to be the touchiest clutch I've ever driven on the street. Sure, it may be great at the track, but stop n go traffic is a bit@h when it gets hot. There really isn't that much pedal travel before it is fully engaged. Slipping it is damn near impossible.

what kind of clutch is it? and did you get a new flywheel, or cut your old one?

500 miles of STOP AND GO. Highway miles don't count.

It is a McLeod clutch. I don't know how I can possibly do 500 miles with this clutch. The pedal pressure is fine, there is just very little little modulation before the clutch engages. After it gets hot, it's even more aggressive.

How are you supposed to launch a car with this type of clutch? I was accustomed to riding the clutch a little on street tires to get it leave with my original Mcleod clutch. That method was getting me 1.8 60' on the street tires. That will be next to impossible with this one.

if the pedal grabs right off the floor it sounds to me like your slave cylinder isnt disengaging all the way, thats why i asked if you reused your old flywheel and had it cut? because if you do so, you are removing material from the flywheel, which the clutch and pressure plate are mounted to. doing this then moves the pressure plate that much further away from the slave cylinder, causing it to grab so early. basically your slave cylinder no longer has enough travel to fully disengage the clutch because the pressure plate is too far away from the slave.

Now, with the new setup, the clutch grabs towards the top of the pedal travel. I've adjusted the tick mc to grab a bit towards the middle but I think it may be still a bit too high. Right now, the clutch pedal sits about an inch higher than the brake pedal. I think the correct placement for this clutch may be adjusting the clutch pedal to where it is right in line with the brake pedal.

Most manufacturers send a break-in sheet with their clutches. We suggest reading it and following it during every install.

Our kit doesn't allow you to choose where you want the clutch to grab at, it allows you to adjust the amount of fluid the system flows to enable a complete disengagement. Go back and readjust our kit using our adjustment instructions, setting it where it needs to be rather than where you want it to be. Otherwise, you risk damaging the clutch, and we definitely don't want that!
