Thread resurrection from 5 years ago. LOL
A few other for the list
- Raised redline from 6800 rpm to 7300 rpm (cut-off at ~7400 rpm)/lightened internals
- Chassis, suspension, interior, seats etc.
- Available torque vectoring differential
- Transmission updates
- 2020 RCF has an updated intake compared to pre-2019 that give +5 HP
- AVS on 2017+
- 10.5 x 19 and 9.5 x 19 wheels
- I believe the Brembos on RCF are different as well
I made my own list of things I found different compared to the IS F I owned. Which is why this will be my next car.

Real carbon fiber
F Emblem seats

^^^^The brakes are in fact different. Both the ISF and the RCF have 6 piston front caliper Brembos, the RCF's front rotors are a bit larger. The ISF has 2 piston rear calipers, the RCF 4 piston. The rear rotors are the same size. Both came with 19" wheels. 8" and 9" on early model ISFs and 8½" and 9½" on later models. The RCF wheels are 9" and 10".
As well as the wider wheels, tire sizes are different 225/40 & 255/35 on the ISF. 255/35 & 275/35 on the RCF. The 2020 RCF has SL MPS4S earlier MYs had SL MSS tires.
The 2020 RCF also has Launch Control.
I believe the intake assembly is the same on all MY Lexus RCFs.

Cool. Thanks for the information. I had some suspicion that they were different, but good to know. Thanks.
