LT's didn't come with 18's. Only the SS came with those.

Fwiw. I doubt that big brake kit would clear the LT 17 inch rims. Pretty sure from reading Mississippisunburst's thread, those brakes are a tight fit with the SS 18's.

Thanks George, I corrected my question.

Oldblue, That would be stock LT wheels. I'm thinking the answer is no? However, I did see Breembo calipers with a smaller disc (another thread on this site) with the LT stock wheels. What are some other options to improve performance that will help with short rotor life? Do the slightly larger (~1") rotors with the repositioned stock calipers offer an appreciable improvement in these areas? Also, thanks for the add: I've already thoroughly enjoyed the site!

I have the non Brembo SS 11.65 inch rotors and caliper brackets on my LS they do a nice job over and above the stock 10 inch stock rotors, and they fit inside my stock 16 inch steel rims! So they would easily fit inside your 17" LT rims!

Yes, my wheels would have cleared the calipers without either the spacers or the studs.
