Hey IS guys(GS owner here)....was wondering if anyone can PM me the measurements of the rear upper glass where a roof spoiler would go as I have a non lexus vehicle I think would be close to an IS but need a measurement before I buyone. Thanks in advance!

 

not sure if this will help you but some have taken the BMW e90 acs roof spoiler and made it work on the is300.

That's a start at least....thanks for the input

but the link won't let me view anything since I'm not a member. All I really need is a measurement in inches.
