Just to chime in here.........

I totally concur with @Tcoat (this time .... ).

I maintain that for most all highway driving (non track) in the US at least, that the OEM brakes on most cars are adequate to stop the car, even under the harshest down hill use (assuming you use gearing wisely).

For example I came down off of Pikes Peak (14,000 ft) in my old MX-5 (with OEM brakes) as fast as I could and still keep it on the road and when I was stopped at the mandatory brake check station, my brakes measured up real good (I didn't even have to pull over to allow them to cool down).

Now, I'm not saying that "big brakes" are not good for the track ...... just not beneficial for highway driving.

Would that be the same supply sergeant that told you that those boots are the right size ....... (they'll beak in ......).

Except I didn't have stock tires or wheels. I think you missed that part. Otherwise trucks would have miata pads...

Sort of like the old story about the 8 old boy, who never had spoken a word, was sitting at the breakfast table, when he exclaimed "THIS TOAST IS BURNT".

His parents were astonished and said out, Johnny, you CAN talk, why haven't you ever said anything .... ??

He replied ...... everything was OK up until this point ........

( ....... is it ma nap time, yet ...... ??)

Now, that wouldn't be OEM, now would it ....??

Ya I was already typing when you said you had 18" wheels (irrelevant to braking power) and wider tires. Even then does not mean you would not have stopped in the same distance since you still would not have overpowered the stock system with a wider tire.


Your truck comment is just silly since of course they are bigger. They are bigger OEM systems.


I know you may not know where I work but take my word for it that debating brakes and/or airbag systems with me would be like me telling you how to fly a plane. I don't care what the internet theories are about bigger aftermarket brakes and day to day driving I have the facts at hand every day.

So why do you think that a wider footprint on the road or larger brakes/rotors can't stop in less distance? I'm very interested to hear your theory on how how are brakes are created equal.

I didn't say a larger foot print would not stop you shorter I said a larger footprint with OEM brakes will stop you in the same distance as with larger brakes.


Again, the OEM brakes are designed to hold longer than the tires will hold grip. Having anything bigger gives no advantage until heat becomes involved. End of story.


There is a huge advantage to having bigger brakes in a racing situation but that does not transfer over to regular driving.

Now I'm no professional but I kinda gotta go with P1lot here. Just because the stock system wouldn't be over powered doesn't mean larger brakes couldn't reduce your momentum faster assuming the tires weren't over powered

I man bigger brake calipers, not necessarily rotors

ALSO bbks should come with"better"than stock brake pads

Ok so you were completely lost because I had 18" and wider tires with a much larger footprint AND Brembos. The braking performance was AWESOME compared to stock.

How do 18" tires make give you more surface area? Presuming still at stock outside diameter of course.


Not "lost" at anything and thought I was very clear.

How are the pads "better" if the stock ones have not surpassed their abilities?


You guys think that the OEM system just barely stops the car? There is a huge safety factor engineered in there.

Your master cylinder is only so large. You do have better brake feel with a lot of big brake kits, but assuming the same tires, your 60-0 brake distances aren't significantly affected.
