I would like to check, how well is the aftermarket brake for 285mm rotor?
Is it about the same as stock?

my concern is, now my WHP is near 200 and i still using stock brake system.
my wheel is using 4 bot instead of 5, 2nd reason is i using 15" rims.

so if i using 285mm rotor type and branded caliper ( in complete set)
will it help for near 200 WHP? ( example evo, wrx, CTR are above 200hp and yet their stock already more then 320mm)

any recommend complete set brake for 15"
