will they fit, off a VW Bora???

Getting mine refurbed and have been offered a loan of these...

any help appreciaed

No!

16" in the minimum.

was thinking if getting some 16's as track wheels

haha cheaper r888's

I always thought that to a point, smaller wheels were better for track use anyway. Well, tracks with lots of twisty sections and the like, maybe not so much for top end. Smaller usually = lighter, less momentum to lose when breaking, less mass for the engine to turn in acceleration and they heat up faster as they have less surface area to make them nice and sticky! Assuming they won't get too hot! :bananadea
