it is possible

 

You can possibly shaved off 500 lbs or more by replacing all the body panel with carbon fiber. Unfortunately, most of the aftermarket body panel weights just as much as oem because their process is stone age. You got to run stress analysis on it prior and determine how many plies of 45/90/0 or uni you would need to achieve a comparable strength as the oem panel. Lastly, pre-preg carbon fiber is much better than wet laid up. Takes the guessing game from mixing epoxy.

 

500lbs? I don't know about that, 500lbs is a HUGE amount of weight for a car.

 

If you want a fast Evo you have to take out as much weight as possible. At some point you take out so much however that it's not really an Evo anymore.

Any time you build a race car you read the rules over and over and build the car to those rules. Does this make a car an Evo? No more than what you see at a NASCAR race is a Ford or Chevy.

 

the HKS car is not tube framed
from the articles i've seen, the weight was closer to 2400lbs

 

Going to cf body panels won't shave 500 lbs. look how large the hood is and it weighs 20 ish lbs, the trunk is about 22 for the trunk, and the roof 26 (steel roof) not the aluminum one. That is most of the skin on the evo and completely removing them and not even replacing them would only save you 68 lbs. I highly doubt the fron fender, 4 doors and rear quarter panels and pillars are gonig to account for 432 lbs. Especially since the front fenders are already aluminum and the doors have aluminum crash beams.

 

Dont forget all the cables of harnesses,guys.Trust me,they weight a lot !
Oups, i forgot to mention:heater/buttons ect

 

When you drop that much weight your not even really driving a street car at that point. Surely not one that's worth taking for more then a trip to the track, you'd hate yourself on any drive longer then 15 minutes with the noise that you would have to listen to.
