@DannyP's right- weight is so important if you're looking to get the most out of your car!
"I can't even process how much unsprung weight you carry with those big cast iron AC Industries hub/rotors. Isn't the whole point of our cars performance and light weight combined?"
I got a close look at an ACI hub/rotor over at a friend's place and couldn't believe how heavy they were. Remember, any added weight to the car not only affects braking/handling, it affects acceleration as well.
"Best investments so far on my car: Airkewld brakes, Vintage 190 wheels, and homemade front anti-sway bar. You see how they all have to do with braking and handling and lighter weight?"
Hey, you're building the car to be fun, right? A few prudent choices just make it that much more fun.
Danny- on the front did you go with the 2 piston cast, 2 piston Wilwood or 4 piston Wilwood calipers? Did you look at the Coolstop Brakes at all?
Do you know what the Airkewld brakes weigh? Kevin Zagar told me his front brakes weigh 47 vs 53 lbs (iIrc) for Karmann Ghia disc assemblies. Al (and sorry Bob for the thread drift...)
