absolutely love my 06 GS430 but the handling thru curves is awful.
maybe I was spoiled by my Audi but it's really frustrating how poorly the car takes turns at speed.

would a sway bar be enough or do I also have to get new springs and coils? also any suggestions on where to get whatever parts are necessary would be greatly appreciated.

cheers.

 

Swaybar definitely the first thing u wanna upgraded in order for better handling.. Strut Tower Bars Second.. Brand # F-Sport@ Sewell Lexus

 

thanks bud.

 

You want to be extremely happy with your Lexus, and have it handle like an Audi too? Get BCRacing Coil Overs.
I had them installed and immediately felt like taking my GS460 to the track, boy was I impressed!

And this is coming from an E60 M5 owner who tracked his car all the time!

 

Lower springs and sway bar will help a whole lot. I would suggest those two items strut bar as well but the first two create a huge difference.

 

I did sways first and noticed a big difference, after adding my BC coilovers I compared it to my wifes E90 (2011 335i sedan) with sport package even though I'm still trying to find the perfect setting. Made it even more fun. I have to remember to turn othe trac off otherwise it will always engage when hitting corners, lol.

 

BC coilovers and f sport sway bar front and read and your good. Have that setup and I'm taking turns as if I was in my drift car.
