Porsche brembo caliper brake swap for 473$

After you get past a shakedown phase and get it dialed in, it would be supremely cool if you could record/report those findings either in this thread or a new one. I couldn't find any specs for 60-0 braking tests for the stock Dusters of that vintage with a quick search, but I bet they're out there somewhere on the interwebs, and I'm betting it's somewhere around 140-160 ft...

Mopar Action magazine did a somewhat UNscientific test.
Their "Green Brick" 1969 Valiant....They were doing a Viper caliper swap and after swapping ONE side, they took the car out and did several brake tests. Viper caliper on one side, iron single piston on the other. The car stopped straight each time. There was no braking advantage for the Viper caliper in their limited testing.
Where I suspect the advantage is....Is in repeated hard usage. The iron caliper may start to retain heat and fade while the aluminum caliper would more easily dissipate heat and continue to function. The gains in weight reduction are minor but worth something.
I'll readily admit though that I do like the look of the modern brakes!
