Ok, well we've established that powerstop doesn't make front rotors that fit a celica st, only a gt. The only options that I can see is return the front set I got for a gt and get summit racing front rotors that fit the st, only problem there is they are silver and the rear rotors I have are powerstop and are colored gold. Second option is convert the front to gt brake components. But I was just wondering, does anyone know if the rotors on say a 96 corolla are the same as an st? If they are then I'll just return the set of gt's and order the corolla rotors.

I just checked and the corolla have a different part # vs the Celica ST's. I think the corollas are actually 4 lugs vs the 5 in ours thats prob why.
Have you thought about buying some off ebay? That gold is just paint and it will eventually wear off. I bought a set of mine off ebay a while ago that was cross drilled and slotted. It worked pretty good.
