    Cp5555

    Posted

    I'm in the process of getting new ap cp5555 brakes for my r32 gtr. The only problem is I don't know the model number of the calipers to suit the r32 gtr's.

    CP5555T1000

    CP5555T1024

    CP5555-802S4

    CP5555-803S4

    Would anyone know what ones to get?

    Also are there any brake stores in melbourne that specialise in these ap brakes for a decent price.

    I'm looking at getting both front and rear. Thanks

    Further to what others have said calling a caliper a street caliper is not a criticism. Look at cars like 997 GT3s that dont have the ceramic brake option. They can pound around tracks like Spa lap after lap with no brake problems just with some Pagid or Performance Friction pads (talking to owners that's what they tend to use) These are cars beign driven hard often on slicks.

    So street calipers are not inferior per say. What they are is generally heavier and constructed from more durable materials. Race calipers can often be similar in physical size, often identical in piston sizes but are often lighter and made from material that makes them stiffer and lighter. This sometimes means due to their duty they are lifed more frequently as they are designed for performance, not durability. They also often run titanium pistons and bridge ducts or water lines for added cooling and performance.

    Short of people actually racing their GTR where they are running for 6+ laps at full speed with sufficient engine cooling etc to permit such use....the Alcon etc kits will be fine for your application. Many people complain about certain AP its and I have heard the same complaint about Alcon Evo guys saying they still use loads of pads and eat rotors. If/when you need to replace a rotor forget about weight and unsprung weight and get a rotor with 70-72 vanes. Dont go running 24, 36, 42 vanes as you will run out of pad pretty quick.

    Of the people I know who run setups that run a 35mm thick 72 vane rotor they have never had a problem with brakes, had an appetite for rotors or calipers with them running nice and cool.

    Thats the main reason I like the AP CP5555 over the Alcon, simply because they take a 375/378/380 35/36mm thk rotors where as the Alcons must run a 32mm and typically 365mm. It just means that 1 in 10 person may exceed the Alcons ability where as 1 in 50 will exceed the AP setup with thicker rotor.

    Also if you are sourcing Alcons then it may pay to check local pricing now that PWR have relinquished distributorship as the pricing is a load better. If you get stung for customs/GST then I think it could well be cheaper to get locally, but if you send the front brakes to your mate at work and the rears to your home address you will probably get away with it :)

    so would you recommend a 35mm thick rotor on a street car that would see the track every so often or go a 32mm thick?
