If anybody has done the 4-pot conversion, can you tell me if your 01-03 Tokico caliper pistons had insulators or were they hollow? The earlier Tokico 4-pots had crimped in non-removable ones and my stock 2-pots have removable insulators. I just bought a set of 2002 GSXR 4-pots and there are no insulators and I'm wondering if that's correct.
