yes, I really do need a smaller belt. but don't know how to figure it out.
any advice?
that full belt drive conversion had a spreadsheet for working out the belt size! they are for those fingertech belts but they run the same pitch 3mm so If you measure between the two axles (the rear pulley axle and the centre drive axle) and input the size of the pulleys it should give you a size close to what you need even if you use the fingertech belts they are stronger anyway.
what about the D3 rear belt? do you have a spare or are they too small sorry it's to long 183T and your zero is 177T I think
A bit off topic here but I am looking forward to next years racing here (AU) Our V8 SuperCars is changing it's format from holden (GM) you probably seen the pontiac G8's that's made here in australia we get a different variant without the twin grills the holden commodore but anyway Holden versus Ford is what the format has been now for about 20yrs but they are finally going back to allowing other manufacturers to compete yay go Nissan, but they still have to be V8's I think.
