Shop Car Update - StopTech Brakes & More - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Carolina Dyno · 12-16-2013, 09:58 PM

We've been really busy with customer builds and PRI but we finally got a chance to get back on the FR-S for a bit. We mounted up the front Trophy Kit with 328mm x 28mm rotors which fit and look great. The rear is a bit more involved.

Fronts:

Currently StopTech only offers an even bigger rotor for the rear that has to clear the factory e-brake assembly. This is a lot of extra un-sprung & rotating mass and that's really not what we're after here. We really have no use for the factory e-brake so we decided to remove it all together. We also removed the factory dust shields because they are large steel pieces that incorporate the e-brake mounts.

We machined some hub spacers to replace the e-brake assembly (no geometry is changed) and took some measurements for the rear hat. We'll be using 322mm x 22mm rear rotors with some off the shelf hats from StopTech but well have to machine our own caliper mounts for the Trophy ST22.

Rears:

We will be offering these as a kit as soon as they are tested on track.

We've also started on our turbo kit so look out in the Forced Induction section for an update on that shortly.

Nice!

Let me know if you need some help with the track testing; I'm usually at Sebring every month

Any chance you can weigh the complete stock rear system with the drum hardware? A few of us are curious about the weight savings possible from the rear brake setup.

Just went back there and weighed everything. I might not have found every single piece of hardware from the stock setup but they came in at 29lbs a corner vs the StopTech setup I'll be running at 20lbs a corner.

We've been slammed at the shop with the holidays but I did have time to get this drawing finished up for the rear rotor hats. We should have these on hand soon and move on to the caliper mounts.

Nice, I have the 328 front setup too. Id love a rear setup

Carolina Dyno · 01-11-2014, 07:13 PM

The rear hat is finished up and mounted. Stoptech was able to send us some lines that will fit so all we have left is the caliper bracket... and some wheels that fit.

mrk1 · 01-11-2014, 09:09 PM

So if you make your own hats does that mean you don't need the hub spacers?

Poor wording on my part. The "hub spacers" don't actually change any geometry. The factory dust shield & e-brake assembly are the exact same thickness. All the spacer does is replace the thickness lost by removing the dust shield and e-brake.

If you look back at the first picture the top right picture shows that assembly and the bottom left shows it being replaced by the simple aluminum spacer instead.

If that spacer wasn't there you would have to have shorter axles and the wheel offsets would change. I edited the first post to avoid confusion.

Oh ok alright, makes much more sense

We've been working on the powertrain side of things for a couple days but I took a couple hours tonight and drew up the rear caliper bracket. Hopefully we can have these on the car before the end of the month!

Question on the e-brake delete. This is a really interesting project with no useful resale value except for owners who never drive their cars on the street. Are you planning on selling the rear wheel kits for track only use or is it just an exercise to see what happens on your own car?

Interested as well. My FRS will always be a DD, with focus slowly going toward the track after it gets paid off. Gonna need an e-brake but I LOVE this setup

what's the capability of the 28mm kits vs the 32 mm ones when it comes to FI and track days.
