Brake Caliper Piston Seal Sizing Sumitomo 4 Pot & 2 Pot

[666r32]

I need to replace the brake caliper seals on both front and rear calipers on my R33 Skyline GTS25t, and am just wondering whether the parts are different between the front and rear calipers? i.e. would the seals in a kit for the front calipers also fit on the rear calipers?

Probably not as I imagine they will be different size pistons

P/No's for seal kits:

Front: 41120-30P25

Rear: 44120-43P26

No, i sell them on ebay, diffrent seal sizes between front and rear.
