    Spec stage 3+ horrible engagement

    Recently installed a spec stage 3+ w/ steel fw, and I've got a couple complaints and I'm wondering if they can be solved.

    first and foremost, All of the engagement is at the very top of the pedal stroke. Any way to adjust this so it happens half an inch further down?

    Also my clutch pedal seems to vibrate/shake, is this normal?

    I thought the throwout shaft had two different placements for a high or low engagement point. But I haven't had a chance to actually install mine yet.

    My engagement is also at the top of pedal travel. The throwout bearing can be put in 2 ways which changes the engagement point. Engagement is nowhere near as smooth as stock during break in and that may be what you feel, that will improve but not disappear.

    Engagement point moving up some with a new clutch, especially a performance clutch is kinda normal... but it shouldn't be allll the way up or something may be wrong. As for shaking... is it shudder in the drivetrain when it's engaging or just strictly the pedal? Two separate issues there. If it's just the pedal you probably have something funky with the throwout bearing, which could be linked to the engagement point as well. If it's shuddering in the engine/trans engagement point, well I never really liked spec but the 3+ isn't a button clutch is it? So it *should* be smooth-ish, but you never know. It's going to be a bit harsh and more on/off switch, so if you try to ride it it's not going to play nice.

    I just put about 500 miles on my spec stage 3+ with the steel flywheel. If anybody really thinks a clutch/flywheel combo like this is going to drive and feel like a stockish clutch probably should have put some more research into there purchase. With this clutch you can still pull out from a stop with no throttle if being smooth but it will chatter a bit. The pedal grabs at about half way and is fully engaged about 80ish % to the top on the low TB setting. I feel the car drives great with this combo and my wife can even drive it. To be honest short of the heavy clutch pedal its really a decent DD combo for those who need the torque capacity.

    I'm running a SPEC Stg. 2 +. It seems that the engagement point may be a bit lower with the throwout bearing in the lower position, but it's still too high in my estimation. BTW, SPEC used to provide they're own adjustable throwout bearing, AFAIK they now provide the stock piece.

    Although my clutch is fully engaging before the top of the pedal travel, it can make shifting smoothly a bit more of a challenge in certain conditions.

    I've mentioned it to SPEC -- most recently at BimmerfestEast --and I'm hoping they'll eventually change the design.
