from the CIS to digi conversion thread
i plainly and clearly stated, that under normal [HEAVILY STRESS THE WORD NORMAL ], daily driving conditions, and on normal roads at normal speeds, your factory brakes and factory brake sizes are more than adequate to do the job. they were engineered to stop your vehicles weight, at its maxium speed in a safe distance. modding your engine to twice the normal power output will not drastically change your vehicles top speed, which is limited mechanically via your gearing ratio.
that being said, under NORMAL road going conditions, the only brake upgrades that will be needed for a modded/heavily modded car will just be moderate brake upgades: like slotted/CD rotors, stainless lines, good pads and a higher DOT rated fluid will suit your needs just fine.
if during daily driving conditions, you, more often then not, drive your car hard, flooring it, speeding and constantly wait till the very last second to SLAM on your brakes to stop at every light, then you might want to do stronger calipers and larger rotors. to alleviate brake fade.
if you use your modded car on the track/autocross etc. then you are also a good canidate for major upgrades.
*****also if you are going to be using your brakes for track use, then you might want to look into buying brakes that were designed for track use, MOST of the kits you see clearly state that they are NOT intended for track and racing conditions/use.*****
basic point,
the nesesity[/b] of upgrading your brakes depends on 2 factors
1) how you drive your car
and
2) what you use your car for,
normal use,
daily driving w/ occational fun,
bling factor,
street/strip/track
or
strip/track only
that is all...
