2015. It says “Lexus” on the caliper. Then in 2016 and up, they had F logo. Rcf and GsF calipers are all the same.

E Brake support, too? More info on the adapters would be useful. Could not get your website to open....

Is3502.0 is the front adapter.
gsfsc3001.0 is the rear adapter

yes the ebrake works just like stock. Toyota uses the same exact sized top hat on the rear rotors.

Will these fit behind 18" wheels?

My 18” CCW Classic Race did NOT clear the RCF Brembos. Don’t know if this is helpful to you, but 18s are gonna be hit or miss.



This is according to CCW’s engineering team. Every wheel is different, but I believe most 18s will be tough to fit.

For this reason, I chose LS460 front calipers and Supra TT rear calipers. I don’t track the car, so upgrading to 6 piston Brembos doesn’t serve a practical function and I saved a ton of money too. I paid $220 for remanufactured calipers from Rock Auto. New seals, hot tanked and ready for paint (I intend to sand them smooth to get the Brembo look though) and that includes the Core charge.

Hope this helps.

I do not think so. well the rears will fit but the fronts will not. This is for GSF/RCF calipers. GSF/RCF calipers uses 380mm rotors.
ISF front and rear caliper will clear 18" wheels tho.

if you have the wheels you can try this template: https://www.350phi.com/is350_bbk_template.pdf
looking at your pitcure, it's the spoke or offset design of your wheels that's hitting the caliper.
stock 18" ISF wheels clear ISF brakes. also stock 18" 2014+ IS350 fsport wheels clear ISF brakes too.

Yeah, the bolts are an issue too. I have three piece wheels, so those bolts sticking out create more issues.
