Last time I went to the track I decided not to do this. I guess I'm too worried about scratching the top with my helmet by accident.

Nice list!

Eric

 

Do C5's have bumper supports?

 

I believe the bumpers are supported by the frame.

The 'skid' bars up front cant be removed either because they support the radiator.

Dayum...nice list J! I certainly can't add to it.

Thanks

 

Expanded and reorganized. <img src="gr_stretch.gif" border="0">

 

Ill just have to add this to my favorites for when I get a vette <img src="gr_grin.gif" border="0">

Do they make Carbon Fiber Half-Shafts? Where?? $$ ??

 

I could never see myself doing this to a vette. I mean we all buy new cars becaue they are fast and still have AC and all the comforts, right. We defile a brand new Vette just to go a couple of thenths or so quicker? Oh well, just me, carry on in your quest for loosing weight, hehe!

 

Definite differences between the performance philosophy of a "chassis" guy and an "engine" guy.

Chassis guy says....PUT IT ON A DIET!!!

Engine guy says....HMMMM, I gained some weight over the holidays...GUESS I NEED MORE TORQUE!!!

I am going sub-sonic with the CD player and the AC on....SEE YA!
