Phwoah, that's a bit steep bro!
With some modding, the TA04 pulley is in, and I've got a "semi-dodgy" idler pulley/belt tensioner setup.
Put the 1 way in the front.
Took it for a drive. It's definitely more oversteery on the throttle, and under brakes obviously. But I'm not getting the big counter steer yet. Played around with the suspension and weight a bit, but I think I need those centre pulleys Phil, so the rear is geared even higher.
How it is now, the rear wheels do about 1 1/8 turns to every 1 turn of the fronts.
I thought that would be heaps, but I'd like to try more.
