Je dis juste que mettre du H6 en arrière ça ne sera pas assez pour sentir la différence de freinage si tu gardes les disques stock en avant... Et tant qu'a payer pour metttre du h6 en arriere, j'acheterais un kit 4 pots / 2 pots complet
dans le cas du setup WRX 2pot av. et 1pot ar.+ H6ar. upgrade je comprend...
Mais dans le cas d'un setup qui a deja des 4pot avant, mais toujours des 1pot ar. je crois que c'est un belle upgrade, VRAIMENT pas cher sutout si ton rotor est du pour etre changer.
rear caliper: 2pot vs h6
#1: Bigger rotor = more brake torque
“Rear H6 caliper” upgrade (a misnomer, but nice and short.)
Gains: Moving to a larger (290mm) solid rotor yielding moderately better heat dissipation and more angular advantage for the caliper. Replace the caliper brackets and rotors (retaining your calipers and pads.) Regardless of the caliper you’ve got, you will also need to bend or remove the dust shield or replace the entire backing plate (probably not worth the effort.)
cost: 50$ per brakets and 50$ per rotor brand new.
Subaru Sti Rear 2pot upgrade.
Gains larger and vented rotor(290mmx18mm) and 2pot opposed piston rear calipers yielding all gains above plus excllent brake feel and uptake, and reduced caliper flex. You will need to replace calipers, pads, backing plates, and rotors.
cost: +or- 1300$ brand new.

I am curious how you equate less dive to more stopping power. Please explain. Also, does your car have a flux capacitor?
Who equated dive to stopping power? Bigger rotor = more brake torque... surely you aren't arguing the H6's don't give added rear braking torque
Is your position that dive is a good thing, regardless of stopping distance?
What I said about braking power was this...
You ARE leaving rear traction on the table with the stock rears...heck, even with larger rear rotors, its still a front heavy bias. Using the larger rears goes utilize more of the available rear traction, and there's pleny more to be had...AKA, look at the bias on the 06 setup. That is why it is entire possible that the H6 setup can actaully shorten stopping distances.
I don't even car about a potential few feet, more to the point is that dynamically, the car is much better. And I'm sure with your motorsports experience, you know the OBVIOUS dynamic benefits there are getting away from a front heavy biased car...
Stoptechs/4-pots ALL move bias rearward...just as the H6's do....so whats you problem?
Bottom line: Ideal braking would be AT FULL braking, both front and rear tires using 100% of their available traction. The H6, 4-pots, 06 combo, stoptech, etc. ALL WORK toward that goal.
When you have fronts using 100% of the tires traction and rears using something LESS than 100%, you are leaving STOPPING POWER (i.e. traction) on the table. Period.
