the exedy OEM clutch option is better than the stock clutch yes. they have many options for different cars.

for a focus, the stock clutch starts to slip around 200wtq.. the exedy oem clutch/flywheel doesnt slip at 240+wtq.

the company i got my turbo from tested it on one of their cars and said it held up great to the abuse of the track at over 240wtq..
