Don't try centerforce dual friction, they ain't any good.For some reason the have problems with car that has high rpms.I had one,my friend with a rx7 had one.My dual friction came apart at high rpms in 3rd gear,so did my friend with the rx7...They work real good in the american car,like mustangs,etc..Get a 6 puck with springs in it....As for flywheel,i don't think it a good idea,to much tire wheel spin in 1st gear and it may bog in second gear too.The oem flywheel help to control the wheel spin or like a type r 15-16 pound(THAT Only turbo cars).My friend got a civic runiing 10 seconds,he install a lightweight flywheel he hates it.If its for the streets ,i wouldn't install one
