Lexus LS-series (LS400 LS430 LS460)


The luxury sedan that started it all - the ubiquitous Lexus LS. Lexus' flagship luxury sedan sets the benchmark
for the automotive industry, and Daizen Sport Tuning adds even more performance to the mix. Tighten up your control over the road, and dramatically improve your Lexus LS driving experience.

Daizen Sport Tuning products are designed to work seamlessly with your Lexus' advanced suspension design and engineering. Acting in symphony with either the OEM suspension or other upgraded components, you will experience the best of both worlds - comfort and performance.

Daizen Sport Tuning products are designed and produced to meet or exceed factory standards for quality and reliability,
so 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 assures that your LS receives what it deserves - the best that the market has to offer.

OEM performance shortcomings

Factory-stock Lexus LS models suffer from very conservative suspension tuning, especially in the sway bar department. This is evidenced by significant body roll during turns, and not-so-confident handling - especially at higher speeds.

Daizen Sport Tuning OEM sway bar bushing upgrades provide a noticeable improvement in the reduction of body roll and chassis response. Sizes available for all iterations, including vehicles with original air suspension.

Bushing upgrades

Factory rubber bushings deteriorate over time, and degrade your LS' 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:
  • 1990-2000 LS400 - Front upper control arm bushing failure - these OEM upper control arm bushings are actually plastic bearings, which increase in play over time

  • 1990-2000 LS400 - Rear strut rod bushing failure - normally the OEM bushing disintegrates due to its small diameter and high stress location
Electrical issues with higher mileage

As with any vehicle, over time you will begin to lose conductivity with many of your LS' 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 LS 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.
