Can anybody please point out the differences between the standard side sills on the IS 350 and the ones that come in the ground effects pakage? I've looked at pics with/without the ground effects pkg and I really can't tell any difference on the side sills... the front and back are easy enough to see but the sides I'm at a loss...

 

It is pretty minor, but if you have the front and back lips, you'll notice that they drop lower compared to the standard side sills. The minor difference in the standard and ground effects package is a little less than an inch, and is noticable when "staggerred."

 

Yeah Phillips right, you cant really tell a big difference on the side sills on the groundeffects kit, but when u have the entire kit it just makes it flow.

 

i saw a car with the kit at a meet this weekend. The side ones are exactly the same visually, but I think that without it, and having only the front and the back, you would have a car that was like (rear)____-----___(front)

 

i tried to look for the difference this weekend at the aerotect meet. its VERY subtle but i think i noticed that the ground fx lip is flared out just a lil more than the original.

 

Subtle is the key word. That was Lexus' goal, they didn't want to make anything ricey or pimped out, keep it classy. I was told by my sales mgr. that the reason they went with HKS as the dealer option (when it was an option ) was that it was the most subtle.
