GB SVT/986 Boxster Front Brake Brackets for Fiesta ST - $525 (Extended to mid-July)

[HAHAFiST]

Good point. I added some additional part numbers for some alternatives to the instructions - Dynamic Friction is a decent alternative I've been looking at. I also found some Brembo part numbers for the UK spec ST170 Focus, which is identical to the US market SVT Focus rotor, but for some reason isn't marketed here as such, but can be purchased from various vendors.

Can vouch for Dynamic Friction being a good alternative. I also really like Bosch quiet cast but not sure if they have the SVT size option.

Please add me to the list again.

I picked up a ‘99 986 for a track project so I am going to have a set of these calipers when I go to upgrade the brakes on it. These calipers feel better suited on the FiST after driving both for the last 6+ months on the street and track. The 986 could use larger front calipers/rotors (996/S) & the GT3 master cylinder so folks are always upgrading from these calipers and they are easy to find for sale.

I'd like to go back to the 615k+ for regular use, great double duty. Currently i have 200tw for my race and summer use and then All Season on stock wheels for daily/bad weather use. It's a good system but switching wheel sets can get tiring

Hey Everyone! Since wheel fitment is a really tricky business, I have come up with a 3D-printable "fitment jig" that I hope can be used to test wheels in a more straightforward way than the paper template. See the link in the original post if you're interested in trying it out, its still very much in development, so as always, your mileage may vary

Thanks to @Stubborn Approach and @RockinPaco, a couple more fit checks for the list:

The good news:

We threw on some other TD Pro Race 1.2s I had laying around just for fun. Looks like 17" wheels have tons of clearance.

Team Dynamics Pro Race 1.2 17x8 4X108 ET48, these fit the calipers no problem.

Team Dynamics Pro Race 1.2 17x7 4X108 ET38 (I think), these should fit no problem.

The bad news:

Pro Race LT. 15x8 ET35

Needed a 12mm spacer so the inner barrel of the wheel could clear the caliper. Then the caliper is <3mm from the barrel. I personally wouldn’t feel comfortable with the clearance. The wheel rotated but, it's probably too tight to be safe.

That means for 15” wheels, it’s likely all down to how generous the barrel clearance is to the millimeter. Some other indications that the 15” PR 1.2 while heavier than the LT, has slightly better brake clearance, but to be confirmed. OZ Ultralegerra are also a possible cantidate, as are other wheels where the spokes meet at or closer to the rim face instead of being inset

Photo they sent of the 15” with 12mm spacer - unfortunately it’s awfully snug in there

It looks like I’ve only got 5 signups so far and need 10 to actually kick off the order. I’m going to extend it another 2 weeks, and see if we can pick up some more interest

Finally did a test of the 3D print fitment jig. First version was a little off (too conservative) near the base of the spokes, so I’ve uploaded a corrected version accessible at the same link.

I printed at draft quality and 10% infill to keep it a fast print and save material. Hopefully it’s self explanatory, but the tool goes inside your wheel, the round boss goes in your wheel’s hubcentric ring, and the flat face up against where the hub mounts with the lug nuts. See pic inside my Dekagram (you can kind of see the place I adjusted the jig where it looks too close even though the actual caliper clears)


The rest of the jig shape represents the location of the caliper and the rotor. You should rotate it back and forth to make sure the spokes clear everywhere. Check your wheel weights as well. Unlike the paper template, the print is sized to the *actual* caliper - the required 3mm min clearance is not included already. You should be able to slip the 3mm shim in between the jig and the wheel at *all* points in order to have sufficient clearance.

The STL print file also includes a 1” cube to verify the dimensions of the jig are accurate, as well as a convenient 3mm shim tool for checking clearance. The whole print is sized to just fit on a 180x180mm build envelope so even small budget desktop printers should be able to make it.
