Hi, Wanted to know if they are just for looks, lower the pressure in the wheel housing, for tranny & diff cooling???????? Just curious, as I was looking at a car online with them. Thanks!

They look good. I believe the rears are fake, and the fronts vent the engine bay just like stock.

Actually, I did find part of the answer....one was for the A/C condensor & one was for a cooler for the overdrive.

They helped cool the twin intercoolers on top of the motor.

The front ones are primarily for looks however, on the 1988 Callaway Sledgehammer, the rears were functional and open (but closed on the production AeroBody)

I hope this helps

All the vents on the sledgehammer were used, on a production kit there is really no use.

Those rear coolers are only on the sledgehammer.

On a production kit, there are black pieces behind the vents that cover it and house the rear turn signal. The rest of the vettes dont have those coolers.

On the front of the sledgehammer those fender vents pulled in air to the turbos.

on a B2K callaway, the turbos are not pulling from there, so basically they function as stock, letting some heat out.
