The fun is in keeping your license since you arent getting busted street racing a fast car.. Or getting caught doing 140 in a 65 cause you had to beat the Vette next to you..
Curtis.. Leaded race gas will give your 02's about a 50 hour life in the car.. If its a track only car it means you can go a season or 2 without replacing them.. I would replace them every season as SOP..
As far as creating an all out race car.. First thing first.. Get rid of the IRS and go solid rear.. It is a waste of metal in the world of drag racing..
Then get rid of the weight.. Everything comes out of the car and I mean EVERYTHING.. Seat belts, sound deadening, speakers, amps, carpet, seats, take the dash out and gut it.. That includes AC vents, controls and ducts, radio, airbags, VMM, any metal brackets that serve no purpose other than supporting that dash (you need maybe 5-6 bolts to hold the dash in place when you are done.. Then move onto the engine bay and yank out the AC and power steering pump.. Basically remove anything that will have nothing to do with the car moving forward, backward, or stopping.. This is where it stops getting cheap...
If you wanna know more hit me up with a PM.. My 95 Talon is a little bit farther along this stage right now as I have about $3000 worth of carbon fiber for it but here is a picture of it the week i bought it 3 years ago when I decided it was going to be an all out race car (please disregard ugly ~~~ hood it was replaced with a CF one)
And here it is after that day. Note the not-yet-gutted dashboard, center console, sound deadening and engine harness are still in the car. Those were removed after this pic.
These are the most current shots of the car with ZERO interior in it except for the gutted factory dashboard that weighs like 10lbs now.. The only other thing going in the car is a 5lb Kirkey Race seat.
If you plan on going all out race car be prepared to spend ALOT of money.. If anyone tells you anything different then they never attempted to build one.. LoL
