Lexus isf rear brake bracket fit on isx50?
Hi, I'm about to buy a big brake kit off a lexus isf. It comes with 2 piece rotors, brembo 4 piston and a 355x32 rotor with bracket for that caliper. My question is, will they fit my lexus is350? I know this has been asked many times, when I searched , it was mainly about the front and the hub. I currently have stop tech st40 345x28 rotors and calipers.
Does anyone know that it will fit? And has anyone put isf rear factory brembos on their is350? Specifically a is350? I want to know if the bracket is direct fit for for the isx50. Thank you

The IS250, 350 and F all use the same rear knuckle, hub and brake mounting points. The only differences are the caliper, rotor and backing plate. IS F rear brakes or big brake kits will fit the ISx50 without issue except ISx50 models manufactured from December 2012 onwards as the mounting bolts to the knuckle changed size.

yep jeff is right. ISF rear caliper is a direct bolt on to 2nd gen IS using ISF rear rotors. nothing is needed.
For the front ISF rotors, you can either swap out to ISF front hub and use ISF rotor. Or you can just use 2013+ GS350 F-Sport 356mm rotors. This gives you the same size rotor as ISF but the top hat is offset correctly to line up the rotor to the caliper. no hub swap needed.

I am currently looking into putting the ISF rear calipers on my 2012 is250. I looked up the VIN and found the car was ordered 01/2012 and first used late December 2012. Would this mean my vehicle is using the different sized mounting bolts?
