Cheers for any info provided..
The 75T spur will work, best if you have a high rpm motor.
Best alternative is to get a '15 spec slipper setup (2 pad) and drill out an Associated 69T spur to fit. Opens up your gearing choices. With a 75T spur, you can only fit up to a 33T pinion.
For anyone's interest regarding 17.5 in a 4WD buggy. At the recent New South Wales, Australian state titles, the fastest 17.5 drivers race times would have made A main in modified.
