Those look pretty dang good for 2 seasons of drag racing Simon !!! new coating is an easy fix :thumb:
Looks like the edge of carbon build up.
Hit the pistons with some contact cleaner and a little scotch brite, i bet the coating appears...
what about the rings aren't those the things that go bad on those pistons
Just checked sig Aria's:thumb: Not to get O.T. but were did you order yours?
How many runs are in a "season"
