Over the past few years, its seems like more and more regular cars have multi-piston brake calipers like the new subaru impreza. 10 or 15years ago, even performance oriented cars didn’t frequently have those until you went pretty far up market. And it doesn’t seem like it is for marketing, since it isn’t often advertised. If single piston calipers were good for an audi s4, why does a new subaru impreza need multi-piston calipers? have there been developments in cost or technology?
This is exactly it. Most people just think bigger brake = better, but 99% of people aren’t tracking their cars and it doesn’t make a lick of difference in any standard driving situation (just about the only time it does matter is towing a heavy trailer down a big hill)
