actually 95-00 calipers will bolt right on, the problem with them comes from the fact that because they are 2piece ALUMINUM calipers (and the TT calipers are Steel) they are extremely wide and foul on the lower balljoint stud. this can be corrected by either shaving the bolt down (not recco'd) or getting a Roll Center Adjuster. the GS guys have been using the latter method for quite some time, however they arent widely available for the LS yet.
The TT calipers will bolt right on without modifications, but they are MUCH more expensive as well as being Heavier than the 2LS setup.
How much clearance do you have between the stock caliper and the back of your wheel spokes. That would give the pros more info to help out. Also measure in metric "millimeters". Hope that helps a little bit.
Don't recall all the numbers now...the TT Supra rotor was like 12.7", the 95-00 LS was 12.4". The rotor on the 1-LS is like 10.X. Do the conversions stick with the stock sized rotor or go bigger?
Rough clearance, you'll need about 3/4" from caliper to spoke in the new caliper position. You can check with the wheel manufacturer to see if these are spec'd for the 2-LS. If so, no worries.
ehh, i don't really like to do it this way but if they ALMOST clear you can throw a 5mil-10mil spacer (with extended lugs) to make it work....
assuming your wheels are already conservative offset.
