Yep, still using them. I've got 4 pots on standard discs with S14 std pads with Earls S12 hoses which bolt straight on. They make a big difference but now I've got some drilled/grooved S12 discs from Mtec (ebay) but I can't decide on the pads to use. :)

I've got a set of 4 pots. Need to pull my finger out, rebuilt and fit em.

I'd prefer to use larger discs though

Does the R31 Front caliper need a "spacer" like s14 one?

I'd prefer a plug'n'play stuff without spacers

northerner dose everything just bolt up or is there some modding ?

The calipers bolt on fine but you either need to use the S14 bolts or have the S12 ones shortened. Then you need to make Two 4mm Pads spacers for either side due to the thinner S12 discs. I used some Ali which were cut and shaped be an exact copy of the back of the Pads. If you do this they will be held in place by the Two pins which hold the pads in place. Then I used some S12 Earls hoses which bolt on but you could use S12 Rubber hoses with some banjo bolts. :cool:

can s14 disks be used ? i know they would have to be re drilled
or could s13 disks be used ?

do you have any pics of the hoses ?

are you sure those are 4mm each, as they look only 2 mm each, just haw they look mate.:)

They need to be 4mm.

The S12 discs are 22mm thick, the S14 ones 30mm thick
