Lexus RX-series (RX300 RX330 RX350)


The market's reference standard in mid-size suv's, the Lexus RX is the ultimate urban daily driver. Mild mannered and stable, yet able to
take on anything that come its way, the RX is a truly unique and amazing vehicle. This advanced mid-size platform responds well to upgrades and modifications, and Daizen Sport Tuning answers the call.

So that you can be assured that you will have trouble-free performance for years to come, all components are engineered for proper fit, installation, and performance, and are thoroughly tested and validated for thousands of miles before they are approved for production and sale. This guarantees that your RX receives what it deserves - the best that the market has to offer.

OEM performance shortcomings

The RX-series chassis reacts very favorably to simple sway bar bushing upgrades - this easy upgrade significantly improves handling and high speed stability, and along with our other chassis bushings, transforms your RX into the sure-footed SUV that it was designed to be. Applications available soon for all RX models.

Bushing upgrades

Factory rubber bushings deteriorate over time, and degrade your RX' driving stability and performance - and even your safety. Daizen Sport Tuning steering rack, OEM sway bar and control arm bushing kits restore your suspension's solid, sure footed handling. Some of the more significant problems are as follows:
  • 1999-2003 RX300 - Front lower control arm bushing failure - the OEM lower control arm bushings experience an abnormally high level of tension, due to the McPherson strut design

  • 1999-2003 RX300 - Steering rack bushing failure - OEM bushings disintegrate due to fluid contamination and environmental deterioration
Electrical issues with higher mileage

As with any vehicle, over time you will begin to lose conductivity with many of your RX's electrical connections and terminals.
Resistance increases, especially to the all-important ground pathways, and many of the components on a vehicle as complex as the RX begin to lose their smooth performance and reliability. Daizen Sport Tuning grounding upgrade kits alleviate many of these problems, and with their high quality fully soldered and insulated connections, will give great electrical performance for many years to come. Unlike other generic and knockoff grounding kits on the market, Daizen Sport Tuning grounding upgrade kits are the original, and are the only grounding kits specifically designed for each model vehicle. Kits come complete with necessary hardware where applicable.
