Thanks for the advice so far, i greatly appreciate it.
You'd be shocked to know that *gasp*, the power levels are still stock and i plan to leave it that way for as long as possible.
Admittedly, my desire for some sort of quality aftermarket brake kit might not sound like a completely rationale one to some.
Let me try to give a number of reasons why.
1. I like the strong initial bite that big brake kits or rather more accurately, larger calipers with greater absolute biting force can give. I know i can somewhat replicate this using the larger brakes as you guys have mentioned, but what i dont want to do is to go down the simple route of upgraded pads and discs which provide greater brake response via a better coefficient of fiction.
2. One of the side benefits i like about complete bbks are the (typically) lighter weights of the aftermarket caliper and the (usual) 2 piece discs that result in noticably better steering feel.
3. My location makes it difficult to source 2nd hand miata bits, i could pick up the phone and order brand new, but i'd imagine that if i was going to shell out good money for brand new bits, i'd might as well go all the way with a good BBK. (I think the term BBK here is somewhat of a misnomer, since i am technically looking for something that can fit the 14s)
4. Further, the car is already 14 years old and i would prefer to replace worn bits with brand new ones, not something i'd have to worry about sometime down the road again.
I guess i am hoping to replicate my good experience i've had with 6 pot AP caliper kits on a Mitsubishi Evolution 8. I would imagine the beneficial effects would not be as great since the brake componentry on a miata do not weigh much in the first place.
Many Thanks again
