Ok so here is a weird one. Maybe I am just not in the know but are all 98-05 GS front brake rotors the same? I was under the impression they were.

TireRack lists two different part numbers for GS300 and GS430. Any idea? Maybe this affects the rear dust shield contact issue?

also, check to see the rotors themselves...I had the 25555 before my supra conversion and they are cross-drilled. My money is on the disc design itself

When both rotors are laying flat down on the ground, 25603 will be taller by 0.3mm. The difference is so small, I wouldn't worry about it. The calipers should be able to accommodate the difference.

Your the man.

The 25555 is $30 cheaper then the 25603. That's an expensive 0.3mm.

nvm its the 35555 that's the cross-drilled
