(10-30-2016, 12:07 AM)NZScott I do get really bad vibes just off idle (shakes entire car side to side) but above that you can't feel much. The flywheel balancing guy said lightening the FW as much as I did it would be impossible to get it perfect, the original FW was quite off balance and he ended up welding a weight onto the pressure plate (visible in a pic above). Wish I had a neutrally/internal balanced engine. Hope my turbo engine is...
Yup stock 215mm, I put a new kit in. Going to take it all off before I ruin it from slipping too much, I would then basically have enough bits for a future 4 speed conversion for another 123.
I was browsing for 240mm clutch bits after getting some advice from F.R.A.S and come upon a SPEC clutch kit rated for 440 ft-lb (~590Nm) meant for a BMW 535i. 240mm sinter. It was $140 USD unused 2nd hand as opposed to $490 new, a no brainer really, over here LS clutches are too big and Jap clutch kits (RB26 etc) are $800-1400. Going to get the oldest of my 3 617 FWs machined to fit it and rebalanced. Will be interesting as to what weight it is because the BMW flywheel is flat. Might have to get weights added to the PP again.
But specifically did you notice a rattle noise from the gearbox in neutral idle it's known as the getrag rattle the noise goes away when you press in the clutch I'm asking this because I'm trying to determine whether or not the weight of the flywheel is the cause or maybe something else, I'm also getting vibration that travels through the driveshaft and makes a rattling noise n rear axle at certain points between deceleration and acceleration at low speeds, my engine does not vibrate though it's smooth throughout the rev, i had the FW match balanced.
