I have run my car numerous times on indoor asphalt and it is the stickiest surface that you can imagine. I would suggest Black fronts with grey or white rears. You will build up a ton of front traction after only a few laps.

This is at the rcscrewz track.

I can post a good setup that I have used there if you want. It is for my L4, but I can help with a knife also. Someone else runs a knife there.
