I noticed Lexus has a factory installed modification package for its Lexus GS series. Unfortunately, it is tought finding a Lexus GS to test drive that has the L-tuned package to compare ride and handling. So to anyone who owns one of these cars with the L-tuned package, please post some details on the changes you noticed in ride, handling, interior noise etc. I test drove a BMW 540 and a Lexus GS430. The BMW certainly handles better, but I like the Lexus for all its other qualities better. So I am wondering if the L-tuned package helps make up the difference between the 2 cars a bit. Thanks

The LTuned package is basically the Ltuned suspension, a LTuned steering ECU, and a bodykit.<br><br>You can purchase each of those seperately. The LTuned suspension is basically the Eibach Springs/Bilstein Shocks & Struts combo marketed under LTuned. This GREATLY improves the handling of the GS. Its your choice in buying LTuned or Eibach/Bilstein (this probably will be cheaper). The LTuned steering ECU eliminates the steering wheel freeplay. You can switch lanes with a little tug of the steering wheel.<br><br>I notice a big difference when I installed it (ECU costs $130), with the suspension upgrade (Bilstein/Eibach combo $500-$700 depends where you go). The handling is much more tighter, especially in corners & aggressive lane changing, and the steering response is on point. The body kit is ok, if you are into the body kits.<br><br>The ride is stiffer, but not harsh. If you are ok with BMWs ride quality, than this is a little better than that in terms of road feel. You still feel comfortable, but the "floating" is reduced at high speeds. The springs lower your car by about 1 to 1.2 inches. Giving it a sportier look.<br><br>You may get some interior noises do to you changing the dynamics of the car's suspension,but nothing major.<br><br>Hope this helps,<br><br>Lee
