You guys are missing out on the simple stuff, but little things that make it all cushy and [******] that everyone ****** and moans over.
Take a look at the GT3 porsche and 360CS, or more so what they don't have.
Seats: Stock seats are nice but weight a ton. Get something more race orientated and you can drop 40lbs easy
Carpet: Or lack there of, you would be amazed how much that carpet and sound deadening crap weighs.
Cats have to stay on from the factory, but you can always cut them off.
Ditch the 19's and run flats. CCW or Kinesis 18's all around will drop a considerable amount of weight.
Wanna drop more weight, lexan windows all around are a good start but leaning towards track only setup.
Then onto little things. Remove the spring hood and trunk/hatch hinges in favor of simple billet pieces.
A/C if you gut the dash, heat exchanger, condenser, compressor, etc. thats a good 50lbs.
You can drop 400lbs from an SRT coupe pretty easily but will be giving up some of the cushy stuff. 200lbs comes easy with little negative side effects.
What would be even better, learn how to drive the flippin car and don't cry so much about little chit. Did you ever see PMUM (rip) ******** about the viper being heavy, underpowered, this and that when racing against FACTORY TEAMS! Nope, and he layed a good smack down on them as well. That should tell you something.
