Brake Calipers: Simple Upgrade or Replacement

Hi, my car is a USDM 91T, mostly stock. I want it to be a well-kept street car, and keep it pretty mild, with more of a focus on upgrading worn-out parts with new or refurbishments.

Regarding brake calipers, I have a handful of questions I was hoping you experts could help shed some light on. I'll write them below. Thanks!

Are there any aftermarket, new front calipers that are compatible with the stock 91T brake rotors? Will they need new brackets? I have light 15" wheels and would like to keep the same clearance as the original, and keep the weight down as well. My driving style doesn't require larger, heavier rotors and calipers. Most kits I see are of course BBKs, but I actually just want new calipers that are better or on par with stock, and stay pretty close to how a stock MR2 came.

If refurbished stock brake calipers are the best choice for my needs, where do you recommend buying from? I'd definitely prefer a brand new set of calipers, but I imagine this might be my only route.

Thanks for all the help! I've seen so many calipers but cant seem to confirm whether they can be compatible with the stock rotor sizes and brackets.

I know this doesn't really answer your question, but BBK doesn't have to mean heavy. I sell a big brake kit that will save you about 10lb compared to the stock brakes. However, they won't fit under 15" wheels, so probably not an option for you anyway.

There are no bolt on caliper upgrades for the stock rotors that I have ever heard of.

Hi Alex, thanks for the info! If you aren't aware of an off the shelf caliper that works with stock rotors, it wouldn't surprise me if it's not out there. And thanks for the suggestion on the lightweight brake kit, I like it a ton, but that + a new set of wheels to accommodate it is outside what I can spend right now. Would be nice, though!

Good pads, fluid and upgraded brake hoses will make the stock 91 brakes work well. Unless you are taking the car to the track you shouldn't have any issues with stopping power.
Obviously good working calipers is a must too. You can buy new refurbished calipers or rebuild them yourself if you are able to.

Thanks! Yeah I am in agreement, for my purposes those brakes work well. It is very challenging to find the refurbished turbo brakes online; do you have any recommendations on sourcing those? Or do you know if I could have the dealership source calipers for me?
