I installed the R1 Concepts drilled and slotted brake rotors and pads up front on my 2015 Lexus GS350 AWD. The look and performance are really good. I have ordered the same set up to install on the rear.


R1 Concepts drilled and slotted rotors.

 

I'm actually changing my brakes and rotors tomorrow. I was thinking of going this route like you did for my fsport but people keep telling me keep it OEM. How does it feel when you brake?

 

The braking is very good. My brother n law sent me the information from Corvette owners forum and there are a lot of positive reviews on the R1 concepts brake package. After the research I felt comfortable trying them out and I think it was a definite upgrade over stock. My car was on original pads and rotors with 48K miles.
