Ya, I have a 07 GT (M90). I have basic upgrades just exhaust system and KN intake (homemade). I was getting like low 9s all day! Then I did the ice trick and WOW! That older man new what he was talking about! And I removed my spare tire and let some air outta my tires to help with traction! I can't wait to get all my stuff put on then run! But when I get it on I will go to MMP. Or if im still in LA I guess I will find a track there. It just has to be open on Sunday
