Now that I've got a GS4, I'm ready to do some improvements in the handling department. The GS is completley stock w/16" wheels. I've visited l-tunedparts.com and am leaning towards purchasing the following:

1. TRD Strut tower bar
2. TRD Lower suspension brace
3. TRD Front/rear sway bars

I'm hoping to achieve less body roll, a more stable backend, and a little less "floating". I'm not ready to lower the GS4 with new shocks/springs like ltuned. Also, correct me if I'm wrong, but I don't think that simply upgrading to 18" wheel/tires will improve handling performance to the extent of the above mods.

I'm wondering how much you guys have paid to have these components installed? Did the Lex dealer do the install or was it a performance shop? I'm located near D.C., so if anyone has any recommendations, please pass them along.

 

Those componets will achieve exactly what you want to do even with stock 16" wheels....

 

You won't get less float unless you change the stock springs/shocks.

But you sure will have less body roll and a tighter feel overall.

 

Im going straight to the source when I do mine Bilstein and Eibach .

 

Prepare yourself to possibly catch some flak if you ever have any visits to your dealership for sounds or handling complaints. Even though they are the same components as LTuned, they "aren't LTuned". Catch my drift?

 

Knowing extactly what you done on the car is very import when dealer start to ***** on you and blame every possible problem on aftermarket parts... does matter if its related or not. I know this when I went through my dealer to fix a problem related to suspension..

 

Which is why I had my dealer install everything except the steering ECU. Granted they screwed up the sway install, but eventually they fixed it, no cost.

 

Does anyone know of a Lex dealer in the D.C. area qualified to install these components? I don't trust dealers at all when it comes to performance mods, including l-tuned, UNLESS they are experienced at it. I don't want my car being the guinea pig! Actually, I leaning towards SRT to do the installation for me.

Whatchu guys think?

 

Ask for Master Mech to installed parts. Don't let the JR Mech touch aftermarket parts.

 

i would definately recommend the TRD sways!!
they just work very great!!, i have the TRD front sway, and it gives me a much heavier sterring feel just like the BMW 5 series sport, i also have the TOM's front brace which makes the sterring even tighter and heavier, just the way a sport sedan should be!!!

 

I think SRT is a great choice. If they can't get it right, no one can. Plus having a rapport with one of the biggest Lexus tuners in the country CAN'T be a bad thing.

 

Since my dealer said they will install Ltuned I think I will go with them and get front and rear sways.
