Mike, how do the EP four pot calipers compare to the AP offerings? It's a good £100 more, has EP offered a reason behind this?
I best answer this one!
compared to the AP5000 ones,
* differential bore pistons - ie, leading edge pistons are smaller, trailing larger - this stops pad taper with wear.
* machined from solid ali billet 7075 (as opposed to cast) - far stronger and more importantly, more ridged.
* Hard anodized throughout - not only prevents corrosion, but also gives a much harder wear resistance.
* internal oil ways - no external pipework round the calliper - less prone to FOD.
* Titanium Pistons (optional) - not really for weight saving, but more for better heat insulation pad to fluid.
then, EP do several versions of them:
1) Front 4 pot direct replacement for standard 2 pot (as in same effective bore sizes to balance with std rear callipers), with fitments direct to upright (no adaptors).
2) Same as above but with a mechanical 'spot' handbrake built in.
3) Same as (1) but with MS offsets.
4) Front 4 pot MS, equivalent sized pistons to match the rears when using either std front 2 pot's on the rears or EP 4 pots above.
All are radius'ed to use from 295 to 330mm disks, and the MS versions can take 28mm thick disks (std is 25.4)
Mikes is having AP 304mm disks all round.
