S14 front brake set up

[PukkaSilvia]

There wont be any need at all to uprate the rear brakes to something from another model.

great how too m8.

as for the rears, these days its not bout uprating the rears, more of changing them to something servicable i.e being able to get the parts easy for it.

BTW, the S14 calipers will work with 315mm brembo discs as supplied by Dans Brakes from SXOC Might have been worthwhile doing that (although bearing in mind that they are bloody heavy, bells would be lighters).

Yeah could be easier to save the hub machining by using the larger M3 discs.

I ended up overcooking some rear brakes, the vented Z31 discs may be a reasonable type of upgrade option if someone was going to change the discs.

Its also not necessary to change the front wheel bearings when its been upart.

Im surprised if you found the std rear brakes to be insufficient

What happened?


A healthy setup with decent pads and at most a few grooves is all that should be needed

On really heavy use they overheated to the extent that they were smoking and faded. At first I assumed the rear calipers were seized on, but they turned out to be free when I jacked the car up.

The vents must count for a lot but don't know if you'd feel the difference unless you are going really heavy on them.

Unfortunately the brakes are great on the S12 but just don't stand up to continued heavy abuse.

Was this still with std front calipers?

i borrowed a bmw disc mart and the disc still will not fit over the s12 hub, it needs a couple of mm off of the s12 hub, do i use one of the holes on the bmw discs as well ?

That's weird when used on an s13 hub the BMW disc is too large a centre bore. You could use one of the BMW holes but it will need to be ovaled a bit to match the pcd. The other 3 will need drilling

i've got r32 calipers now and found out they sit further away than the s14 calipers, so in theory i could use gtr 295mm discs with a 11.5 mm spacer like doski has used, only for some reason r32 discs are extortionate price at £150 each, i'd like to use bigger discs but i could live with 295mm instead of 274mm std ones, i'am not going to be trackin the car only straight lining, so they should be adequate until next year, then i will probably do what you have done mart.cheers for the help.
