there very good mate despite what many peopole who DONT OWN them are going to say they are top quality ive had one of each on the s2 coolers they they have made, changed my first twin pass for a prototype single pass and now im wainting on a new pro series singles pass.

there rads are much more heavy duty then others i seen from grs and rad tech much thicker alloy

i also have one of there turbo coolers too everything mounts so easily and i didn't have to cut anything about

for the price they are id def go for one, i'll def be changing for a pro series rad when they are avaliable
