Caliper upgrade???

Well one factor I left out, it's a 225 slant six.(stock for now) That being said, it's not like I need all that much stopping power. I think my big question is, is there a larger caliper/pad setup I can bolt on to the existing equipment?

Curb weight stant 6 2932lbs
Curb weight V-8 3130lbs

The stopping power is based on weight of the vehicle not the size of the motor. All things being equal. Stopping a 3000lbs car is stopping a 3000lbs car. It wouldn't matter the number of cylinders or displacement.

But a ton of things can influence brake selection and setup. Type an size of tires, weight transfer, suspension, vehicle usage, ability to dissipate heat, driving style, manual or automatic, tune up, federal standards, even the cost of manufacture.
