RR-Racing Motorsports Engineering

Some GoPro 360 action chasing down a McLaren 620R at NJMP Lightening 2 weeks ago. It was a hot 90F track day and a great opportunity to test out some cooling mods and brake pads on our 670whp Supercharged ISF (still bone stock original engine). As always, big thanks to everyone in the Lexus community for your support. We are out there constantly testing our products to make them better! https://youtu.be/9X7da68xDBE

@v12eatr making over 700whp with the RR780 Supercharger kit, C38R head unit and E47 blend! https://youtu.be/1xlLv0bkVKI

After 3 years Supercharged, this ISF came back with 143k miles for some maintenance and a C38R upgrade, resulting in 658whp on E70! https://www.youtube.com/watch?v=6k-UqQlz9AI

There seems to be a common reaction when riding in a Supercharged ISF Thanks @wutduh_f for the video!

@tommyboykim screaming all the way to 8500+ RPM thanks to our bespoke 991.1 GT3 RS Supercharger kit. Own a 991.1 and find yourself looking for a quantifiable performance upgrade (+200whp) while retaining the glorious N/A sound and linear powerband? Contact us to discuss our Supercharger options!

New product alert! Our ISF Front Brake Conversion Kit allows ISF owners to upgrade to the RCF Brembo brake calipers as well as our lightweight RCF 2-piece Competition Rotors. The advantage of this upgrade is three-fold. First, the added rotor area (15" rotor vs. 14" rotor) results in greater thermal capacity. Secondly, the RCF calipers are larger, allowing the use of a brake pad that is approximately 30% larger. The added thermal capacity of the rotors combined with the larg...er brake pads results in significantly improved pad and rotor life under extreme conditions, such as racetrack use. Also, we find that for track use, due to that added brake torque and thermal capacity, a less aggressive pad compound can be used, further improving rotor and pad wear. https://www.rr-racing.com/RR-Racing-Front-Le/isffbck002.htm
