Aftermarket brakes for a 70 Dart?
I agree. But. I bought the complete set up used from a circle track racer that said he had brake fade . $300. (8 years ago) Came complete with spindles and hoses! Everything. Just bolted on. Turns out he had a wrong bolt behind the rotor that was hitting while cornering and heating the rotor up..Yes I'm frugal and would never had bought them at full price lol .
It doesn't surprise me that those wilwoods wouldn't handle circle track racing, if a single bolt dragging occasionally was all it took to create fade they weren't far from it to begin with. Or that they were put together incorrectly, as I've seen that too. Safety wired rotors might be one thing for the track, not a fan of them on the street. Too many people out there that don't know how to safety wire things properly.
72bluNblu, I disagreed with you because I have Wilwood 4 piston disk brakes on all four corners of my Demon. The weight savings are totally worth the expense, I had KH disk and drum combination before swapping. Most days I can make the second cut out at the track with no problem.
That's fine, people use their cars for different things. I would never sacrifice stopping power to save some weight, but my cars get used primarily on the street where the weight of a heavier rotor/caliper assembly won't make any kind of noticeable difference. But the stopping power of the larger and heavier brakes will. If all you ever do is stop 1 time from speed with a large runoff area then it probably doesn't matter.
There was a formula to figure out some sort of h/p? gain by removing unsprung weight vs sprung weight in regards to aluminum vs cast iron/steel calipers, and wheels, it was amazingly substantial .
And if all you do is drag race then that's a big consideration. But for a street going car I'd rather trade a bit of weight for braking power and reliability, both of which are sacrificed by the Wilwoods. And for a road course car the braking power and fade resistance is more important than just the weight.
I'm not saying that weight isn't a factor, but, it seems to me a lot of people that don't make a living racing spend entirely too much time and money trying to shave a couple pounds off their cars, frequently at the expense of reliability and durability. The 13" Viper brake kit I just put on my Duster is heavier than the 13" Cobra style kit that it replaced. Thicker rotors, larger calipers. But it also stops better. So, yeah I'm happy with that trade off, because that's what the brakes are there to do.
