I put in a deposit for GS350AWD Mercury Metallic with Ash and NAV with the G-spider alloy wheels. Does anyone know the handling, cornering and acceleration affected with by this? Will the 18'' tire gives me worse ride than 17' tire? I would think this lighter wheel with bigger tire will give me better handling and traction.

 

lower profile tires give better handling..."fatter" tires gives more comfort.

 

So this G-Spider option that I got should give me somewhat better handling on GS? Just wondering if cost justify.

 

it is a nicer wheel than the stock...but as far as noticable performance difference...probably not...19's with low profile you will notice as well as 20's. 18 g-spyder wheels if i remember right are still pretty beefy with tires...but regardless, they are nice wheels.

 

Quess, I'll try to enjoy it.
