Ran a Team spec T1 for a few months as part of a generous sponsorship package.
Built the car as per instructions and set it up as suggested in the included tech sheet.
Incredibly quick due to the lightweight composites used in the drivetrain. Only drawback was the high rate of wear in the transmission components(diff and input gears)
Basically I was replacing the gearbox input bevel gears before a big race meeting to guarantee they wouldn't fail.
I think they have changed the design and materials used in the gears so they may be a bit hardier than when I had mine. I don't know how the car would go with an 8 turn motor(other than very, very quickly) but it should be extremely competitive with a stock motor, provided you gear it correctly.
I used Peak World spec 2000s, Pro digi RMX ESC, Peak 11D Aurora(Can't remember the spur size but it was a 29t pinion-48 pitch) to gain 3rd place in modified TC at the 2000 NZ On road Nats.
Car was returned about a month later.
