My car setup, speed, power etc, would allow me to safely run three track days without any canvas showing up.
If you want to run some sticky tyres and normally run streeters, on a low budget, or are keen on Calder, the Island or even the SAU expedition to Sydney for a run, then these would be a great option.
There are also drags on, so if two guys with GTSTs wanted some rears to pull some serious times with, then these would also be killer.
FYI, I always get out of the wrong side of bed...
