I have a graphite chassis, I was wondering how I could protect underneath it. I used foam pads but those tend to tear away from the sticky part.
Any ideas?

I have a HPI Sprint 2.

raise your ride height a bit helps i think i still need to make mine higher but it helps save my front and rear screws a little bit longer

I have a Sprint 2 with all the carbon fiber parts.

I used a Team Associated clear chassis protector sheet for my chassis. Not sure if they still make it, it is part #6312. If you can't find one, just buy clear vinyl.

Here's a few pics:

that will work drill some vent holes under your motor to help with cooling
