Personally?
I have a Fidanza Flywheel (8.5lb model), JWT SR20 1 Side Metallic 215mm disc (

click here) (
click here for the combo pack).
I track my car twice a month (one weekend a month, saturday and sunday) with an extensively modded VE and its by far the best clutch setup I've EVER owned. Great for DDing while it holds up the abuse on the track. I had it apart due to me killing my 3rd gear and it was perfect when I inspected it (after a full year of DDing and 24 track days).
Also I will say that while its a JWT disk, the inner section IS an Exedy clutch (as both JWT and Nissan uses Exedy as their "OE" clutch type).
With my prior problems with quality control and ACT, I won't buy any of their products for the SR20 series any more, but thats just my opinion.
