    Whats the deal with the 2 piece discs, whats the benefit? Higher initial outlay, but cheaper to replace just the friction surfaces? Never known the reason behind them :)

    Something like that I think. Obviously a race bread thing.

    I'm liking the anodised centre tho. No more rusty mountings for the wheels.

    I know some cars where the heat conducted to the hub througth the disk can cause problems with melting CV joints on cars with BIG brakes when they are used heavily on track. The alloy bell and seperate rotor will reduce this significantly.

    Its easier to cast and heat treat...

    I would imagin they are machined and/or forged from high grade ally and then hard anodized.

    How are the joined together? must be slots or something as the bell will have a different expansion rate to the rotor.

    Done some work on a set similar before and the disc is located by a step on centre section.
    The ones I reworked required a stronger centre section(used 316 st/steel) as the ally one was causing vibration under heavy braking.
    Anodising only hardens the surface minimally and doesn`t make for a stronger part and the advantages of two piece are less cost to replace and easier resurfacing of discs I think.
    Plus they look better. [8D]

    Having warped several sets of once piece disks, including Wilwood 2-piece versions (twice) I had enough so went looking for somthing better. For me this meant AP disks (quality name, but at a price) and calipers to suit. Mine were 315x28 AP's ally bell and 8 grove rotor. Less weight is one benefit. Reduced temperatures was my main aim as well as higher quality materials which would remain stable at temperatures they run at. (melting CV gaiters is not joke.. its happend more than once as has melted tyre valve caps!)
    These disks have venting which is like a fan duct so sucks air in like a ducted fan unit, spinning it out of the edges. Std vented disks are more random in their venting and do not act as air pumps when rotating so are much less effecient at shedding the heat build.

    My AP's have been superb and given huge grief with ZERO warpage of any kind for 12months track attack. In the previous 12 months the std one piece disks were consumed at the rate of one pair of disks every 2 track days. The AP's worked out cheaper and less hassle for more performance, with less wear and tear (heat wise)

    What I have done is use what I have found from my own bespoke setup and replicated it for regular 4x100 Brembo users who wish to 'Ave it on track. High heat on one piece disks does warp them.

    Come replacement time, new rotors only and bolt kits req'd reusing the ally bells.

    Can you give me an idea of price please Bill (PM if its better)
    Also, can you spec the bell's in other formats? I run 5x100, not 4x100

    bill i think all the fiat coupe boys will want these too, any chance you could do some checking, they run 305x28 too IIRC but in 4x98pcd

    We are doing 5x100 kit at the moment also.. but these are 330x28 sized.

    Drilling the bell for 5x100 in this 304x28 format is no problem but obviously a one off (?)

    These disks are 499, so not cheap, but very effective and durable in my own ibiza bashing experience.

    If you can accept a dual drilled bell I can get this done sooner probably. What studs you running? M14's? (would need larger clearance holes than the 4x100 M12 clearance ones in the picture.

    let me know
    regards
    bill

    Its probably doable but would need to confirm offsets etc for their application. I know VAG stuff but not Fiat stuff. Sample OE disk should suffice if you know of anyone.

    Float the price first and see if there's any interest I s'pose ?

    5x100 uses M14 size, and I currently (I say currently even tho the discs havent ever been used in 18mths!, Doh)use dual drilled dics anyway

    I will have to wait and see what the disc performance is like with the standard kit first and go from there. I had my discs grooved when I modified the stud pattern, but I shall see if the heat disapation and pad performance is good enough before I go any further

    Good to see these bits come through tho, will be keeping any eye on other opinions - any other Ibiza owners running them yet?

    http://badger-5.com/bin/ap-304-blue-bell-640x480.jpg

    I have resized it smaller to fit their BB now.. could you post it?
    Replacement disk prices are 143.47 each anfd bolt kits 10.50/set (one set per disk)
