Scat Pack 4 piston Brembo calipers and rotors

When I was selling brake kits I found that the Mopar market size dropped rapidly as the wheel size got larger. Almost everyone would use a 15 inch wheel but only a few people would upgrade to a 17 inch wheel and almost nobody would go larger than 17 inches. So if you design a brake kit that requires a 18 inch wheel you are locking out about 99% of the Mopar crowd. Which might be okay if you're only looking to sell a few kits a year.
I eventually gave up on even the 13 inch rotor kits since I just couldn't convince Mopar guys to upgrade to 17 inch rims. They just refuse to do it so I stopped trying to sell big brake kits.

Yep, I see that. And honestly when I first looked at the idea of using an SP or GT caliper and discovered I couldn't stay with 17" wheels, I dropped it. And it sat for close to 2 years before I looked at it again and decided I was ok with 18" wheels. I like the proportions of 18" wheels but it's a fine line getting some sidewall without the tire getting too big. Which is one of the reasons I doubt I will ever go above 18".

I do think people are more and more open to 17" and 18" wheels though. If for not other reason than the options for a decent 15" tire is basically nill for anything that might want to carve canyon roads. And you almost have to step up to a 17" wheel if you want to run a 245 tire or bigger in the front unless you want flairs. At the same time, I was on board with 17" rims and 13" rotors pretty early so I could be looking at things with rose colored glasses.

In regards to this setup, I'm not locking anyone out of buying a kit because I don't have any intentions of selling anything. Sure, it would be nice to do something like this for a living, but I'm not excited by the headache nor do I think I could support myself. So I do this for the fun of it and if it helps someone I am glad.
