Thanks for your advice.
I was using a 48 spur recently which sat the motor forward a bit - so going down to the 45 and moving the motor back may account for some of the handling changes I noticed last race night.
I run Contacts, 50mm 35s on the back and 46mm 50s on the front - but have a pair of 32s coming for the rear.
I am also running the blue powder coated rears so definitely could go lighter on them too.
The setup is an alloy chassis with F1 style WBs mounted directly to the chassis with a fair amount of washers to set the camber, castor and ride height. I basically built them up to the same height that I was using with the standard WBs but with the added camber from the 3rd mounting hole.
I run zero toe and about 4mm ride height slightly lower to the front end.
Powered by a Trackstar One Cell ESC and 13.5T on 1S Lipo. Solid rear axle.
Ginetta shell and diffuser.
In your experience is it best to find a spur gear that works well and stick with it - changing the pinion to keep the rollout as the tyres wear down?
