Re;;Atlas
over here at the Barham track in deepest Kent
C2`s are around 5.3-5.5 atlas 4.9-5.1 i reckon it`s around 1-2 bigger on pinion that it will take for it`s sweet spot compared to a C2
the atlas do generate more heat but there mags are of better quality then the Epic ones & can with stand a bit more abuse
