After the surprise success of our 2GS/SC430 brake adapters, we've started development on an IS300 version as well! These brackets let you bolt on LS460 calipers to your IS300 / Altezza, making an inexpensive but VERY effective brake update option! Thanks to Toyota parts interchangeability, that means they also fit Chaser, Cresta, Crown Majesta, Mark 2, Progres, and Verossa chassis'!

In our continuing support of Lexus performance products and the UZ platform, we have finished this set of brackets to mount 4 piston LS460 / LS600h brake calipers to any IS300 2000-2005!

These brackets are ideal for those DIYers that are looking for an inexpensive option for brake upgrades. You keep your factory brake lines in this bolt-on solution; all you need is a set of front 2007-2018 LS460, LS460L, LS500, or LS600h fixed 4 piston brake calipers, LS460 fitment pads, and a set of 2008-2014 IS-F 14" rotors!

Although the roll center adjusters aren't mandatory, they provide a bolt on solution. You do not have to run them, though if you do not, you may need to modify the knuckle and/or steering arm. They will improve the suspension geometry on lowered cars at any rate, so we highly recommend them. We do not suggest modifying the stock equipment.

Please note that the LS460 does NOT use 5x114.3 rotors, so you will NOT be able to bolt on the LS460 rotor. We do not have fitment confirmation on the larger LS460 F-Sport 6 piston Brembo brakes, though they may also fit when used with larger rotors

Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are the Enkei RPF1s. We cannot make any promises on what else will not fit, however many other 18" wheels we have tried do fit over these brakes.

Pictures show the RWD K17 type caliper being used. The AWD N18 caliper has the same bolt pattern, but the caliper sits taller on the rotor. As such, the N18 version will not work with the IS-F rotor. You'll need to stick to the K17 type. Additionally, the calipers ship grey, not yellow. You will need to find a local trusted and competent powdercoater if you want a different color
