What changes do I need to make for my 2003 LS 430 to qualify legitimately for the badge. Are euro struts and larger sway bars and bushings enough or do I have to replace the springs also? Anything else?

Thanks for help.

Yep, Just like you mentioned; Just the Euro struts, larger sways and springs.. and the Badge.

Rear sway only BTW...

The non-Sport came with tires sized P225/55R17. The Sport models have P245/45R18 tires.

I'm pretty sure there are different upper control arms as well, and a different alignment spec. I looked one time and it was cost prohibitive to do the changeover including these control arms... i just ended up putting on the rear sport say bar and bushings and it substantially controlled the rear wallow in cornering...

I guess I'll just buy the sway bar and bushings then. Control arms are too expensive.

Anyone have a part number for the Sport Bushing?

I concur. The sport sway bar works wonders.

Can you bolt on a set of Sport Struts/Springs using the non-Sport upper control arms?
