Skyline R32 4 pot Calipers
Skyline R32 4 pot Calipers
But where do i get the brackets made up ? having never done this before I am in the dark regards next step..:confused1:
Following Speedfreaks advice I went on skyline owners forum and have been offered a full set, front and rear R32 4 pots, discs and pads for £200 delivered. Sounds like a decent enough deal to me..
But where do i get the brackets made up ? having never done this before I am in the dark regards next step..:confused1:

Basically, like most things with modifying cars, if someone hasn't done it before then you will have to take the plunge and figure it out yourself, which takes time and a bit of trial-and-error. I know a chap who did this to fit Porsche 996 front brakes to an MR2 and it was a lot of agro and took him 2 or 3 bracket designs to get it spot on. It's doubly difficult if the calipers aren't radial mount.
PS I think you probably want an RX8 front disc on the rear, rather than the Mazda 323 one. You need to be careful about upgrading the rear calipers though - the MR2 has the handbrake mechanism inside the caliper and most cars don't. If you replace the rear caliper you will either need to get a second handbrake-only caliper fitted (AP Racing make one) or just space the existing caliper out on a bigger disc like the RX8 one, which is actually what that kit I've posted photos of does.
Edit: Here are some shots of a custom one-off bracket for fitting ST205 / Supra brakes to the SW20 hub. As you can see, some complicated angles involved, but it has been done (for the fronts anyway).
You'll need to make contact with some kind of machine shop somewhere who can CNC you the brackets to your/an enginers design (or an existing design if someone's done this before). You will want to end up with something like this, having accurately measured the mounting points on the MR2 hub and the brake calipers, as well as the finished position of the caliper so that it sits squarely on the disc in all 3 dimensions:

I know the skylines 4 pots are superb stopping power, but now wondering if perhaps sticking with the existing MR2 calipers and simply putting on bigger discs is the way forward.... may be worth giving Ant' a call and see if he has one of his bracket kits available.
I had forgotten about this set up till you posted it, thank you.. more to think about now :confused1:
Isn't that the kit Ant' (cantfindausername) did ? From memory it was roughly £200, but he used the exisiting calipers and this allowed bigger discs.

Rabster if you can get some designs knocked up i can get prices on kits to be made up from a few of my contacts in the fabricating world
I have to confess, I wouldn't even know where to start regards getting the brackets designed.. deep sea, out of depth on this one :Fish:

I was going to fit this kit after I'd overhauled my stock brakes back to a factory standard, but my split rims were about 3mm too small for it all to fit!
It is what I would use, if I weren't going to spend out for a WMS 4-piston kit.
Yes that's Ant's kit. It works by using the same calipers on bigger discs. It doesn't sound like it would do much but the extra surface area of the disc dissipates heat more quickly and because the caliper's further away from the centre of the rotating mass it provides more leverage which makes the calipers more effective. It doesn't rid you of the hideous floating caliper design but it does improve your brakes without spending too much and naffing up the brake bias, as well as filling your wheels a bit more.

....or, have i missed something lol
giving it thought, i suppose an ideal solution would be to have Ant's brackets for the rear which means i don't have to worry about the handbrake problem and then have some skyline 4 pots on the front for additional stopping power.. Which would just mean getting custom brackets made up for the front...
