That can be done the next time, for now could you try to remove a shim for the spur side if you placed some in?

2. I had the slipper tightend as much as it would physically go and it was still slipping so its almost perfect but would like to be able to set it tighter still. Solution ??? Thats rather odd. The slipper on my optima mid can be tightened very tightly till the gears growl. its the same design as the B4 slipper so...

Overall its almost there, i had the quickest car there and drove it like i stole it and the gearbox took the strain and the belts are unscathed so great, its possible to shorten the screw section by the slipper by 2.5mm so making the layshaft a bit shorter. I did kill two spurs but may be down to movement of the motor but think its down to slipping. Will change the motor and pinion and test again in two weeks time.

Yes, i can shorten the end by 2.5mm but ithink that is too much, 1.5mm is more reasonable. you killed the spurs at the pad area or the tooth?
