Finally got to drive the car around the block after full Clutch system upgrade. (Zpeed CMACK, EZ street Clutch and LW FW, RJM Pedal with Tilton MC)

I did a search and read a few posts about the Lightweight flywheel and noise.

I get almost no noise or chattering at Idle in Neutral. Sounds normal.

However, when I drive, it sounds like GRINDING METAL.
I did nothing spirited, didn't even get past 3rd gear. I read the comments about sounding like a F250 Diesel, or bunch of rattle cans. Seems to be what I'm experiencing.

Transmission shifts ok. No notches or gear grinding. The RJM pedal is a bit stiff (almost like stock) buy I'll let Clutch and whole system break-in before I adjust it.

One thing I forgot to do, is top up the Transmission fluid. I lost about 1/2 a cup when I did the CMACK, due to those sealed bolts on Transmission input shaft cover.

I don't think that little Fluid loss would cause that grinding. ( REdline MT-85 currently)

So this noise is normal?
