Ok, I just picked up an Xtreme 90cc mini quad and I'm starting to build it up.

I'm looking at suspension first. I see Hetrick Racing makes all kinds of stuff, but who else is out there? I've tried to contact Robbs Racing Engines and K-fab, but they haven't returned my calls yet.

Anyone else out there? Please post some contact info and a website link.

PS - nerf bars are already on it, and tires/wheels are on their way.
