What about the weight saving?
KTec did a two piece 312mm disc that saved either 2kgs a corner or 2kgs overall and this helps with unsprung weight, they dont list the kit now so can't see the weights.
If it was 2kg a corner surlely the 330mm kits offer a weight saving too?
I'm tempted to try the godspeed kit for any other upgrades that may/may not happen in the future.
