Had my MK2 RS forged by Mountune and again great product and great service from the whole team, very happy thanks Mountune
I paired these with the Carrillo rods offered by Mountune and a few other bits. Sent engine away to a renowned builder in Australia and was told that the balancing of these items was perfect. No noise and the added security of knowing I can push the boost levels somewhat are highly reassuring. As usual Mountune chooses it's externals suppliers wisely.
Will be fitting these Pistons with k1 rods , best set up for the st/rs if forgeing your ford.
