It's a great idea. I encourage you to try it. Just be sure you get new rims too though. You'd never be able to see those brakes behind the 15" pie tins.
Another option is aftermarket drilled rotors and those caliper covers, since we don't really need more stopping power and this would just be for looks.
Front bias braking will in fact degrade braking performance. That's the biggest mistake people make when upgrading brake kit. Also please note that BBK adds a lot of extra weight (>20 lbs/corner). If you want cosmetic upgrade, look for painted caliper (G2 paint kit) and drilled rotors. I am really not a fan of fake caliper cover though...
Me either normally, but on this car I think I'm even less of a fan of painting those dinky little calipers red. At least the covers are bigger and have the chance of fooling the casual onlooker, especially combined with some aftermarket drilled rotors.
I more interested in knowing if the CT200h suspension upgrades (springs, brace, and sway bar) will fit the Prius.
i don't think you'll need a big brake kit for a Prius, unless you want it for show. Prius is not a 350z, lol plus installing this kit will ding your mpg for sure
I'd be willing to bet the difference in cost between the Prius you bought and the Lexus CT-200h is about what it would cost to buy that complete brake setup with installation...and like others have stated, MPG will suffer, and you'll definitely be torturing your suspension with the extra weight as well. Doesn't seem like a good mod to me...JMO.
