I really like the 25T front pulley since trying it on the "R". The more even tyre wear helps maintain some consistancy of handling.
I'm needing to consider Lilydale and imagine that Brendale is much more flowing. While Lilydale is large (long straight) it still has a fair bit of twisty stuff.
We ran the front tyres down to 52mm at Lilydale last Sunday 
and the car was handling great.
The engine was tragic, however.
Where did the 26T come from?
The 26T is a Kyosho "Team" part, only available in alloy.
I was actually quite surprised with the advice that came with the pulley which is why I thought I would share it.
You could possibly get the G4 belts in a smaller side belt size (Manticore can you confirm this?)
