Upgrading Brakes... Help Needed...

[ZACK]

Well Their In Their 2011 Dealer Brochures lol

I Haven't Looked At Calipers Yet But They're Next

There's some debate about the effectiveness of grooved or cross drilled brakes as in theory they offer less disc area for braking.......................

Friction is not related to area, so changes in pad/disc area have no effect on the brake force generated.

Sorry to be awkward, but those second ones are just ventilated the difference is they have a gap betweenthe braking surfaces unlike standard solid discs, like most cars have on the rear these days.

Drilled is best
Slotted is either deep grooves or even full thickness slots
Grooved is the closet to standard

Example of drilled and slotted and ventilated discs,

The various features help dissipate heat so reduce brake fade and also help remove dust from the braking surfaces.

To get the best increase in brakes larger is better

But uprated pads and discs, plus steel brake lines and uprated fluid will be almost as good as expensive big brakes on something as small as the DS3
.

These are just ventilated not slotted................

The DS3R uses Brembo assemblies up front, these are slotted only.

Grooved and cross drilled discs disperse dust/heat better than plain ventilated or solid discs, but as Stef says, you're reducing the braking surface area. The best gains are from installing larger ventilated/grooved discs and fast road pads.

Yep, apologies, got my slotted and ventilated terms wrong.

No worries, I blame Zack with his random terminology, he should try "etched and laser cut concrete brake discs"

How about some EBC green/blue stuff pads for starters instead?

[ZACK]

Had Brembos On The Astra, Changed To EBC And Found Them ALOT Better !

Gunna Combine Them With Some 'Green Stuff' Pads And Hopefully A Caliper Upgrade In The Near Future...

but as Stef says, you're reducing the braking surface area.

And as I've said, that has NO effect on brake performance!

.................so bigger brake discs and pads won't make the car stop any better than small ones fitted to the same car then?

Brakes produce a torque, which is calculated as (clamping force) x (coefficient of friction) x (effective radius). Pad & disc area don't have any effect on stopping power, although they do influence other aspects of performance, such as heat dissipation & wear.

[ZACK]

Pad & disc area don't have any effect on stopping power.
