I have a 10LSS with an aftermarket chassis that would be good for velo racing. The chassis is wide on both sides and I believe has 12 battery slots or 6x6. I've had the chassis for 15 years and finally got around to putting it back together a few months ago. Currently it has the "old school" front end on it. The parts were white that have been dyed pink. The LH pod is also dyed pink. I also have body mounts and ride height spacers that are dyed pink. I should add that I didn't dye them. There are decent bearings on the car right now. Also the chassis doesn't have any holes for a servo mount, so that may be a good or bad thing depending on your needs. Oh, it also has the old school gold center shock with adjustable shock collar.
I was going to set it up for a speed run at the Indianapolis Velodrome, but I have a 10L2O or 10L wide car that I can destroy!
I'll try to get some pictures posted
