I have a perrin heat shield, can ceramic coated black. Looking to trade for a grimspeed heat shield. Idk if the gs is much larger? I have a 10cm hot side turbo and a ptp turbo blanket. The perrin heatshield sits right on top of turbo blanket and am thinking the gs is a little larger so I won't have the heat shield sitting right on top the blanket... any ever have both, is the gs even any larger?
