Here is another simple tip that the Diablo builders can use – especially those that use a stretched Fiero chassis:

After installing the rocker panel pieces, drill a couple of 5/16 holes at various locations in the panel and inject some spray foam insulation. This stuff is water proof, paintable and insulates that area of the car from heat, cold and noise. Also, when this stuff cures, it is pretty hard and will help support the panel. But I suggest that you make sure that the underside of the rocker panel has some enclosure or the foam will just drip to the ground. This is especially true for tube chassis. I'm using it and it works great. I'm also using it in some other areas around the wheel well where the body meets the chassis to fill the void spaces. It insulates and does not add to the weight of the car.

The pic of the dynomat is what I used, I have enough to do the whole cabin. Also since i took this pic I rough sanded the inside of the tub and used a 3m rubberized under coating which will also help to deaden sound. I put about 3 layers of that stuff down.

The engine pics can be used to show a different setup for budget builders like myself who want a longitudinal mounted v8 without the cost of the 3,000 + transmissions out there. The trans came from a early model Cadillac eldorado front wheel drive car. this is the trans a lot of fiero guys use to get a longitudinal v8 in a stock fiero. Also notice how my headers dump to the front.

The other pic show the steering support bar for the fiero based chassis along with a photo of the steering wheel center piece. I cut the top off and reworked it to my specs but with the primmer on you can't tell all the work that was done to make it look this good.

the cars sound like factory cars when we finish, after we are finished sealing the inside of the car we use rubberized undercoating throughout before installing the carpet and we also use super insulator on the inside and outside at the firewall. one thing i've noticed different from the IFG cars we built in the past was you would hear squeaks from the steel cage glassed to the body, if you were to glass your cage to the body you need to use a fiberglass filler between the steel and body so you won't have any air voids and could cause the steel to move in any direction.
