Hello, I just got to the rolling-chassis stage of my electric Riot

Hi, let me introduce myself my name is David Bonner and I've been building an electric Riot for hillclimb & sprint.

I would like your advice on tyres. What would be the best choice ultra light, ultra sticky tyres? Avon ACB10's?
The car weighs only 332 kg as you see it. (edited: 350 not 332 - got a sum wrong!) Will add another 25 kg with a rollbar, seatbelts and a minimalist set of body panels (not the standard. I plan to use sandwich material, very light). Can also lose about 30 kilos by using recent batteries (mine are from 2010 and rather overweight) so it might well end up at 330 kilos ready to race. On the current hard tyres there is absolutely silly wheelspin. You give it anthing past 3/4 throttle at 20 km/h, in a straight line, and it's up in smoke. Great fun but not very productive.
The controller is a Zilla Z1K, watercooled, and it's beautifully progressive, you can easily drive at a constant 1 km/h if you press the loud pedal gently.
Still have some bugs to work out in the battery packs - after a few full power accelerations I have a low cell that triggers a fault. The cells need rebalancing.
Also is there any way to reach Jeremy Phillips? I bought the chassis directly from him in 2010, I explained the project and he thought it was nice, so I would love to show him that it actually got ... well sort of ... finished.
Looking forward to our exchanges!
