Is there any difference between the Brembos on each trim model? I'm trying to order a rebuild kit and I've found

CENTRIC Part # 14346018

CENTRIC Part # 14335031


That on RockAuto it says 2005 Evolution. I'm assuming that my MR would have the same calipers as every other trim. But when going to Amazon so I could over night the kit, it says Evolution (EXC MR/RS)

Can I still use these?

 

They're all the same. Technically speaking late 06 and foreign market 07s they changed slightly, but they are interchangeable with 03-06... and has nothing to do with model designation.
The seal kits are the same for all 8s and 9s, regardless.

 

I have 14346018 for the fronts.i drive 03 evo 8.14335031 could be for the rear but I'm not sure.from rock auto.

 

[I'd replace the brake pad retainer pin and playe while you're at it, those tend to get fatigued over time
