both centax's come with their own flywheel and you can not use the stock flywheel with the centax. As far as which is better I would like to hear opinions on both from people that have used them. I have been looking at the Kfactory because it looks smaller in diameter which means you can mount the engine lower and it comes with motor mounts.

go with the k factory clutch. its cheaper in retail and the preformance is better. the clutch just seems put together better too. I though iwas looking at the centex clutch for my serpent impact m2 when i opened the k factory up.
Okay, thanks to all that helped with my problem...here's what I found out. The gears are just tight, I took the car out today (you guys were talking about the weather, it was 75 and sunny today here in the glorious south ) and ran it some, and the gears have worn in nicely. So there is no problem with the new gears and the RD Logics diff cases (as I had worried).
