I recently purchased a 2002 ls430 and I'm quite happy with it. I've seen many of them lowered with all kinds of aftermarket products. I was thinking about lowering mine about 2 inches and was wondering what size tire and wheels would work best. I don't plan on going any larger than 19 just to keep it simple so I want to know what dimention rim and tires would work best.

 

Welcome aboard Richard;
Best suggestion is to read through the many threads and posts on this very subject.
Obviously, the taller the rim, the harsher the ride, but 20's seem to be the most popular/best looking wheel (fills the opening) that I've seen. More tire options with 20's than 19's in many cases.

BC Racing or Megan Coilover shocks are the way to go when lowering, unless you have an Ultra, which has the air suspension. You can install a Datasystem controller to control ride height with the air suspension...

Read through the FAQ's and you'll find loads of info there..
