Lexus ISF is a legendary car, and it has been an amazing platform for us. RR Racing started our Lexus legacy by making performance products for the ISF. We are proud to be the largest performance manufacturer for Lexus ISF in the world! We have the most products and the most advanced tuning. We prove this claim with dyno-testing of our latest Lexus ISF installations.
When RR Racing started tuning Lexus in 2016 (starting with Lexus ISF), there were no commercial tools available. We invested heavily in the effort and testing to develop tuning capabilities. Even then there were “tuner” scam artists who claimed to develop various hardware plug-ins or tunes for Lexus, but their fraud was relatively easy to identify. Today, there are several commercial tools available that are able to write to various Lexus ECUs. As expected, there have been so called “tuners” popping up who have made extravagant claims for their Lexus tuning capabilities. We welcome competition, and we are always on a lookout for technical talent that can supplement our tuning team. Sadly, we mostly encounter “tuners” who at best exaggerate their claims and at worse simply commit fraud. This article gives a few examples of this unfortunate phenomenon to help you identify questionable tuning products.
Continue reading “Buyer Beware!”RR Racing is continuing to improve the power of its RR780 supercharger kits for Lexus RCF and GSF and set new records. Last month we tuned our RR780 Stage 4 RCF supercharger kit to make a record 739whp and 557-wheel torque!
It has been over five years since we first tuned and supercharged the Lexus RCF, and we are very grateful for all the support we received from the Lexus RCF community over the years! This month PPE shipped us prototype of their catted racing headers for Lexus RCF (using 400 cel GESI EPA cats) for our testing and development. We decided to use this opportunity to perform the most transparent and thorough testing of RCF mods. This was especially revealing given the recent trend with some tuners who have released grandiose claims (of up 20-30 hp gains!) by playing tricks with Dyno testing, showing unrealistically low baseline dyno results, and in general advertising dyno results with very little clarity or transparency in what was done.
If you are interested in understanding true RCF performance, you will read carefully this article.

This is a very helpful overview of RR Racing’s impressive offering of Lexus suspension performance products. This video includes a peak into our newest product that is expected to be released soon.

RR Racing’s engineering and tuning is at it again! This time with the help from the new Rotrex C38R blower, we were able to get RCF to 700hp at the wheels.
Brett Charlton set a new time record for installing our supercharger kit for Lexus GSF. Brett installed the kit all by himself in just 14 hours!
We completed installation on our first 3rd gen IS250. The results were amazing! Just see the Dynochart and video on the next page.
Continue reading “IS250 3rd Gen Supercharged!”As many of you know, the roots of our business is in many projects modifying Subaru WRX. In the last three years, we have been hard at work developing the Lexus IS/GS/RC350 platform and making sure that our customers can extract the maximum performance from these cars, at a reasonable price. Our IS/RC/GS 300/350 supercharger kits now produce a reliable 445whp output, all while maintaining the excellent reliability of the stock engine and transmission. We offer a range of other products, such as suspension and brake upgrades to bring these cars up to true ultra-high levels of performance.
So how does the 3rd generation IS300/350 platform stack up the wildly popular Subaru WRX and STI’s? We did a little analysis, evaluating everything from purchase price to cost of upgrades. Here is what we found:
