R1 Concepts ~ Difference between STS & ETC?

[Raze]

I was wondering if someone could comment on the differences between the Seville and Eldorado's brake rotors for the year 1998. I was looking at R1 Concepts rotors and they do not sell rears for the Eldo in a kit but I'm assuming the STS parts are compatible with the ETC? Thanks.

Hmmm. You would think so but I tried looking up equivalent parts for an ETC and STS on rockauto.com and came up with different part numbers.

Nevermind, I called them and talked to them, they're the same rotors, the only difference is that the calipers are different so you can't use the brakepad combos, but rotors only will fit, I'll go with them + Axxis Ultimate ceramics, should be a decent combo but I'll let everyone know how they workout

Before you do that, contact R1. They may be able to machine a pair for you!

They're the exact same piece, they checked, if it doesn't work out I'll just send em back, the guy was really nice and helpful, A+ on service
