A sprung clutch will eliminate the bark, but again aggressive driving will destroy the trans.

I blew the ring gears in an Evo with an OS Giken STR unsprung. Always build the trans to match the power!!

Interesting, is it because overbuilding a trans/clutch combo does more bad then good when compared overbuild an engine ?
My clutch/flywheel knowledge very slim so curious as to why
