GeeEss Posted July 1, 2020 Share Posted July 1, 2020 Hi there, I have an 2003 IS300 that's been running Supra TT calipers / rotors for the last 7-8 years. The car is still running the 2JZ-GE but does have a couple of mods ( R154 & coil-overs). Anyhow; my insurer's premiums are starting to grate so I decided this might be a good time to re-aquaint myself with the fine print before looking around. Bottom line is - the brake situation has me worried. RMS Light Vehicle Modification Guide states quite clearly that non-standard calipers and/or rotors require Certification; which is a deal-killer as the brake test costs $1200-1500 plus; and that bird's never going to fly. That said, the Supra TT BBK is currently sold by quite a number of Lexus dealers in the USA, which would seem to imply this set-up is officially sanctioned. Told RMS about this & they said I would have to contact Lexus Australia & get that in writing. Good luck with that. . . For this reason I'd VERY interested to hear from anyone running a BBK who has filed an insurance claim (esp with Shannoins, Ryno or Enthusiast) and how that process went. I'm damned if I'm going to throw $$$ at my insurer every month knowing I will probably be shafted if I ever need to make a claim. As much as I love these brakes (and they ARE awesome); unless I receive a compelling reason to do otherwise; I will probably convert them back to stock for peace of mind.
