Oh I kinda missed your question... The LS400 calipers are probably the same dimensions as the TT's. My stock wheels clear with a 15mm spacer and it's very close. From what I've seen it's the same with the TT's.

I never came across different rotor sizes when I was looking...

Yes you need to trim the dust shield behind the rotor

Is the RCA LS400 Caliper Kit available with out the adapters since I already have them?

Edit: I saw on the FIGs website the RCA kit is sold separately from the caliper adapters.

Even with the TT brake swap you will need to trim the dust cover.

contact me for a separate quote since we try to sell as a bundle package.
It also came to light today that some people have misunderstood that the LS400 caliper require LS400 rotors...just as the TT calipers require TT rotors. They are different sizes so you need to match them up.

You need 95-00 LS400 calipers AND rotors.
IS300 brake lines fit fine. Same with SS IS300 lines.

I don't remember comparing mine. I'm sure they are heavier, but much lighter than TT calipers so it's still a great upgrade.
