Hi,
My 95 was sitting idle for many many years.
the brake rotors were really rusty. calipers were rusty but not as bad as the rotors.
i cleaned one of them and it is all pitted. Havent checked the others yet, but i assume they will be as bad if not worse.
So, at a minimum, i want to replace all 4 rotors.
found this on lmr https://lmr.com/item/LRS-61041-KIT/mustang-drilled-slotted-brake-rotor-kit-9404
decent enough? is there something better i should consider? stock rotors from autozone range from $42 to $59 each, so this seems like a fairly decent deal.
is it safe to assume that if later i want to upgrade the calipers, i wont need to buy another set of rotors?

current plan for car is to just get it back into good shape and maybe work on 1/4 times. maybe put supercharger back on it. i had the car as is but with the charger on it and stock brakes, never had any troubles (but i may not have been aware i had troubles).

i think i recall back in the day about people getting larger diameter rotors (but i could be wrong), i guess that would involve some type of conversion kit? i dont think i want to get into that at this time, but i could be swayed.

thanks

They are fine for daily driving/street use. I call them "car show" rotors. I wouldn't recommend them for heavy duty racing use however as they will likely crack.

They are likely R1 concepts rotors as they look similar, but I wouldn't be surprised if there were only a couple China shops making drilled rotors for our cars, so i'm sure some packaging/branding interchange is done. If they are not the same exact rotors, they are likely very similar

Anyway, I have the R1 rotors on my car. Was around $200/set. Mine are for the larger Cobra rotors. The zinc coating has held up for 3 years, but my car is a garage queen and doesn't see rain.

To go to the larger rotors, you'll need different calipers up front, and different caliper brackets in the rear. You also would require changing the MC. However....well worth it.

If you're also interested in changing out the calipers, I got the PowerStop KC1300 kit (priced in the $450-600 range depending on where you find it) that has 4 drilled & slotted rotors, pads, 4 really nicely powder-coated calipers, and all the hardware including the brackets. I installed it earlier this year and it's been perfect and looks really sharp (everything stock sized). I've likewise never had a problem with the stock brakes, but then again I don't do autocross or drifting or anything. The car stops as good or better than anything modern I own with the stock setup. Edit: here's a link if you're lazy like me https://www.jegs.com/i/Power+Stop/419/KC1300/10002/-1# - they charge for core, I bought from Amazon and didn't have to return cores (though it was much cheaper at Amazon late last year than it is now).

Best deal on brakes is Callahan brake parts sold on Amazon, remember Tommy boy? Four new rotors and low dust ceramic pads $132

I've been using them on everything from six lug expeditions,to range rovers, great quality and fantastic prices.

when i was young, i remember steel brake lines being a thing. was that just a fad or are they an actual improvement?
i see some kits come with the steel lines, but im wondering if i might as well go ahead and get steel lines if i go part by part.
i think i am going to upgrade everything i fix along the way to getting the car back in tip top shape

Yes, they are an improvement, but a small one. The actual improvement comes more from the forced brake fluid bleed.

realistically, the difference in swell of the rubber lines to the braided is very slight. If you were to do the math of difference in the volume of fluid between the rubber and braided lines, the difference would be so small and translate to maybe 1/16-1/8” less pedal travel. Would you feel that? Not likely.

still...I run them
