Arron 227 Report post Posted August 2, 2015 we have just gone through this with one of our s50b32 engines, our dual mass was naffed. e we looked into a lightened kit from nzad but after some reading and speaking to one of ouf engine guys we have decided not to because the lightened flywheels can upset the harmonics of the engines and can cause flywheel bolts and crankss to break along with other stuff we have had a flywheel made up but have had it machined to the factory weight so we dont cause any issues to have a flywheel made was not expensive at a little over $400 the person who is making our flywheel has made a lightened onoe for a 328 before and 3 days later he gets a call saying he has snapped the crank in 2. (this is assuming of course the kit you hhave been quoted is a light weight flywheel) Quote Share this post Link to post Share on other sites

Could be a good way to have a single mass flywheel with the 240mm clutch setup without spending ludicrous sums of cash! Feel free to PM Quote Share this post Link to post Share on other sites
Arron 227 Report post Posted August 6, 2015 Picked up my new flywheel yesterday We will be using a sprung disk It is only a 228mm flywheel as we have a dprubg disk here for it already, we are also having a pressure plate re built and up rated For us having the 240mm flywheel didnt really achive much, we are only running on clay so there isnt as much grip as a seal track, The guy who made it was from dynamic engineering Quote Share this post Link to post Share on other sites

wrs 120 Report post Posted December 24, 2015 Nice, My D1 Racing Clutch & Lighted Flywheel is coming out and getting a replacement like this although it will use the 240mm disk and standard M3 pressure plate. I've had nothing but trouble with the D1 clutch not fully disengaging since it went in. I suspect there is some issue with the D1 pressure plate requiring additional travel which the S6S 420G slave + release arm cannot provide. However, they cannot offer any technical details or drawings showing the required travel. The lightened flywheel is also causing a lot of gearbox chatter at idle. That flywheel looks pretty nice.

marquis 18 Report post Posted December 25, 2015 I'm running a UCC clutch with a single mass flywheel and the whole clutch setup weight in at about 11.5 lbs. Going to a lighter flywheel, UCC recommended ATF with some Redline 90w-140 to reduce /eliminate chatter. I ran what was recommended and I haven't had any issues. I have put around 2,000km on it as the car is a daily and have attended 3 skid days at Hampton and shifts really well. It drives better than a stock clutch but she can bite like a 4puk. Highly recommend if budget allows. I recall another member running a UCC clutch also in his E36 M3 in his hack car. And he wasn't soft on it either.
