Why do people keep putting 20" wheels on a car that the suspension was designed with 17" (maximum) wheels?? I don't get it. 20's don't look that good. Not worth the reduced ride/handling/performance and added tire cost. Just doesn't make sense to me.
To each their own....
pretty much any car out there can be found with a wheel larger than that it's designed for. it doesn't automatically mean the car is going to fail in some way, shape, or form. i think bigger wheels look better to a certain extent. (nothing more than 20" on an ls)
-reduced ride(not sure what you mean): i rarely have more than 2 people besides me in my car, so thats not a big issue. my winter beater/play toy is a cherokee with 31" tires for when i need increased ride. haha
-handling: i came from a bmw 3 series with just about every suspension mod available for it(struts/springs, front/back sway and strut bars, aftermarket shock mounts etc), so no matter what could do to this, it wont handle as good as that car. not that it handles bad, just not as good....if that makes sense.
-performance: the ls isnt exactly "fast" in my book, so i'm not worried about the extra weight of bigger wheels.
as for tire cost, my ls came with 20's when i bought it, so buying more 20's is cheaper for me, especially since i have a warranty for the current tires. im not trying to argue with you, just giving you my $.02.
