Hola. So, today, I pulled the trigger on a single mass flywheel from TMS, made by JB. It's the 20lb single mass unit that they suggest using with an E36 M3 clutch. Just curious if anybody has any experience using this? I didn't want to go with an aluminum lightweight wheel and ruin ALL harmonic/dampening characteristics, but I thought that a nice five pound drop would help with rotating mass.
I'm debating sending it back for a lightweight wheel for performance gains, but I don't think I'd be happy with a 12lb flywheel clattering around underneath me. I've heard the logic behind not pairing underdrive pulleys with a lightweight flywheel, but maybe the 20lb single mass is close enough to stock that it won't matter? I'm starting to second guess my decision
