really not much difference huh ? just read the size of the brakes and dream you could afford them, that's 3 pot Brembo calipers per front wheel, price ? too much for the average petrol head.

NO.

its 6 pot Brembo calipers per front wheel. it has 3 piston's each side. therefor a total of 12 pistons up the front end.

brake calipers usually are either single, twin, four or six piston.
the single and twin systems on cars have them on one side of the caliper and use a sliding method to pull the 2 brake pads together.

the price for a supercar system would be around the 2,500-3,500. !!

four piston would be more then enough for the weekend on the track. with 330mm or more rotors!

also the slotted (grooved) & cross drilled (spot drilled) rotors are really only for show!!

look a v8 super cars and you'll find that they either have one or the other and not both.
the best pattern would be cross slotted. but curved slots would be better if money wasn't a v8 super car buget!.
cheers

Exactly, but I told you that now didn't I ? info easy to obtain, the sum total of $1500 would not even buy one disk rotor let alone a 6 pot caliper to put on it, in that class of braking gear shown, nor would most blokes using this forum be able to afford that sort of gear unless they won lotto.

After all just one front disk minus bearings may cost you well over a grand in a cheaper quality product on just one part.

No street car would need brakes even half that good.

A cheap dual pot caliper and decent disks would change braking 100% for the average joe, after all commodores have pretty good brakes off the showroom floor, but to change brakes to what I showed you for the VY and the V8 ford supercar would cost a literal fortune, just the master cylinder and bias adjustment gear to drive the calipers would cost more than most average entire cars.

Price the 2 - 4 and 6 pot Brembo calipers (IMO the best) and you will get a basic idea of what it might cost to upgrade your brakes to something more decent than a street car would need, If it matters my last race bike had brembo 3 pot front (each side) and two pot rear, braking was 10 / 10 to say the least.

Sure there are other brands that are just as good, it just matters how thick your wallet is when full of $100 bills ? although a cheque book may be needed for that good gear :wave: .

if they're only for show, then why do brake manufacturers apply them to their rotors? i'll tell you why, relief points in the rotor face (slots or holes) help reduce the build up of gas and dust (by products of brake wear) thus maintaining good pad to rotor contact under heavy application. even on road cars this can be of use, it's not just useful for the track. in extreme applications, cross drilling of the rotor reduces rotational mass but there is a trade off. the less metal there is in a brake rotor, the less heat soak it can handle before it has to either offload it or be forced to glow red hot, reducing effectiveness of brakes unless you are running ceramic or carbon fibre gear and i doubt many people would ever apply this to a commodore.

Too much reading but do so at your leasure, remembering thats the top search, of many thousands.

IMHO hollow rotors for cars with grooved disk faces will work better with no cross, or through drilling as that will weaken the rotor and make it possible of rotor failure, could be an interesting experience at 300 + kph to see your wheel go by.

The pattern of grooves may be done to please the eye, unless the supplier comes of with genuine data on each pattern of slotted faces.

Through drilling was first done on bikes to the best of my knowledge, , when dirt bikes wore disks, us oldies do remember 4 leading shoe drum brakes, i'm still here so they must have worked, bar flash european cars like ferraris etc, that would have been using the current race technology of the day.

Remember I did a lot of racing (roughly 30 years of it) on bikes and drilling of bike rotors is common enough to have it done now on the smallest of stock bikes as std, innitially done for dirt, water, mud, heat etc etc and still have brakes that worked when you grabbed that handle.

But enough said, read away.

Haha only 2,500 to 3,500. Sorry but try trippling that figure and your getting closer to how much it costs for V8 supercar brakes. still i would love a set though! :hit:
