Ross racing pistons

After being in the market for a set of pistons, decided to give Ross a try and have to say the quality on the pistons is amazing.

The only reason for me to give them 4-stars is due to the fact that they supplied the wrong support rails and after sending the replacement rails they were also the wrong one, so I ended uo buying Wiseco support rails.

Other then that, great quality, customer service tries to help as much as they can and if it wasn't for the rail issue, I would've definitely give them a 5-star rating.
