The seats are full carbon fiber(probably about 40% of the weight) I had to build custom brackets for them and surprisingly enough they are comfortable for the street, we really wanted a race seat feel, so these do not recline however they are pretty comfortable.

Right now the car is built primarily as a track car that can be driven on the street, however the side exhaust sounds absolutely phenomenal, the fins on the diffuser seem to work pretty well under smoke. under high speed maneuver ability seemed real fast and loose so I personally feel there's some adjustment that still needs to be done with the coilovers.

Interested in the exhaust exit setup. Did you just delete the mufflers and have the pipe bent in that direction? Do you have pics on the setup ?
Awesome car.

Sorry!,..Just saw this.

Yes, mandrel bent exhaust. We have now done 6 cars, 5 ZR1's And 1 1996 LT1

The mufflers are deleted, so the mid pipe is critical. with an OBX or other mild mid pipe it sounds outstanding. Not over-bearing but refined until you stomp on it.

We will have 1 or two cars at our booth at Corvettes at Carlisle( in the manufacturers midway.)

What a beautiful build.
Looks like EME is a great place for C4 folks in the mid-Atlantic area
