Tristor

Just a quick update, I've got the suspension tuned in and everything installed.  Went to the track on Easter Sunday, and by the end of my 3rd session I was 3 seconds faster than my previous personal best lap time, so I am very happy with the car and my own progression as a driver.  I'll be at the track again this weekend, weather permitting.
Car has significantly changed in how it feels on track, so I had to completely relearn the rhythm, but once I got it there I must say the car feels very good.  I have JDM STI motor mounts, JDM STI transmission mount, solid driveshaft center bearing bushings, and have done every single bushing in the suspension with Whiteline replacement hard poly bushings.  Rear LCAs and rear toe arms were replaced with the SPL parts arms, and I now have the RCE Tarmac 2s installed, everything is dialed in.  My alignment was basically perfect for the tires and track, confirmed by the pyrometer.
Current alignment:
Camber: -3.2F/-2.2R
Caster: +8 degrees
Toe: 0F / 1/16th inch R
Cold Tire Pressure for track: 31 psi

I've picked my camber settings mostly track focused.  I don't really "daily drive" at all since I work from home, but even then, I rarely drive unless it's spiritedly and for fun.  I'd run more camber than this, but I want to start here and see where things are for the tires I'm interested in using a pyrometer on track before making any more alignment adjustments.
All the bushings are in except the rear subframe inserts (Whiteline KDT922) because when I opened the package it had 1 extra of one part and was missing 1 of another part.  Everything else went pretty well though, only took ~9 hours of work in the shop drinking beer with my helper to get it all done.  Having access to a lift, a pole jack, a shop press, air tools, and a torch helped speed things along a lot.  Having a fridge full of beer probably slowed things down a bit.  But all in all, it went well, and the car feels great. I'm doing an alignment check on Monday with a buddy who works at a dealership, but it seems to track straight and no adjustable arms were installed yet and no adjustments were touched, so it should be alright.
Next Saturday, if all works out, I'll be doing the coilovers and arms, but I won't get to enjoy them until quite a ways later because I start work travel next Sunday and need to get a proper performance alignment before going HAM.
Yep, I'm aware the arms are aluminium and only the socket cap screws which lock the adjuster are titanium, but they call it "Titanium Series", so, I do to.

Ah, sorry I didn't read that properly. Don't fit the sways and at the same time as the suspension, you may well find you don't need them.

You should post a YouTube link .

I had the same issue with HLT recently as well. What I found helps is to link the GoPro via its app to the phone (you can also check and adjust settings easy this way), and only then link it via HLT before starting the session.

Also found that HLT looses connection with GarminGLO (10HZ GPS) frequently.

I recently started using Race Chrono Pro, IMO its more user friendly than HLT and also easier to analyse and compare laps as you can see track map with speeds and acceleration/ braking zones (colour coded as well).

That's a pretty stiff setup, 7kg front and rear springs plus anti roll bars. I don't think anyone here is running such a hard setup for a dual use car.
I found my set of PS4's great on track but the grip fell off massively with 4.5mm+ tread still remaining. Still fine for road use though.

I have run a 9/14 with arb's and ran 7/8 with arb's for ages for dual use. The dampers make a massive difference to running the high spring rates though. I wouldn't fancy those rates on cheapie dampers! 

Well,
I had a blast this last weekend with a run around Twisted Sisters.  I was with a mix of other cars, most of which had coilovers, but without even pushing it was able to maintain a comfortable lead.  Even on stock suspension and sport tires, the BRZ is a very capable car in the twisties that puts nearly everything else out there to shame.  Texas is experiencing a butterfly and moth migration currently, so I did my part to protect plants from the coming caterpillar problems.

They just refer to them as "Titanium Series" so I do as well.  I understand that they're just aluminum with titanium hardware.  They are definitely pricey, but I consider it worth it to have strong local support.  If at all possible I always buy as local to me as I can.  If I encounter any issues I can literally take my car directly to them to have a look, I can actually have SPL do the suspension install as well, although there is a race shop that's a partner of theirs called Winding Road Racing in Austin I'll likely have do the install.

Howdy Lauren,
Yep I've been keeping an eye on your build as well.  I'm going to do two more track days with instruction and then see where the next step is.  My goal right now is primarily to focus on things that allow for weight reduction, but a little extra power wouldn't hurt, so I'm thinking a full exhaust and tune might be a next step.  That should let me cut some weight, get 20-30hp in gains, and why not.
For the suspension I'm still split and haven't yet made a decision, there's three different coilover systems I'm considering and I currently have some active correspondence to try to understand what is the right choice for my use case.  Right now is seems very likely I'll end up with RCE Tarmac 2s, which are improved KW Clubsports.  In either case, when I do the suspension I'm going to replace all components in the suspension at once with lightweight components that enable full adjustability.  Then have my alignment tuned at my local performance alignment shop. I'll of course also add the appropriate bushings and bracing to stiffen things up on the chassis otherwise.
I hadn't yet considered modifying the final drive, but that's a good idea.  I haven't touched the diff yet, but depending on how temps play out over the next couple of months I may be adding an oversized diff cover to allow it to hold more fluid and cool itself better, in the process it wouldn't be too terrible to swap the FD gear.  Not sure I want to take that on yet though.
Meanwhile, I'm doing as much driver mod as I can.  I've lost 28 pounds (2 stone), and I've been to multiple tracks and sought instruction at each now.
It's pretty likely suspension will be next up on my list, but I may go ahead and do the exhaust (or hell, both at the same time).  In either case there probably won't be any more part mods until into next year when I get my next tax refund
 

Most carbon bonnets on the 86 are heavier as the oem aluminium bonnet is very light 

I am digging that rear seat delete. 

I've added some weight in the front actually, because I'm running a half-quart more oil and an oil cooler.  Probably going to end up adding some more as well.  I'm planning to compensate for weight balance (as well as get some more space for future brake ducting) by replacing the windshield washer reservoir with a smaller one, getting a lighter weight battery, and doing a few other things.  The stock reservoir when filled to the top fill line is 15 pounds!!!  I'm looking at the PTuning windshield washer reservoir relocation kit, which should cut around 10 pounds of fluid weight as well as losing another 20 pounds by switching to a Braille lightweight battery and battery tray.  As you'll note they're in my list of planned changes this year still.  I'm hoping adding hood louvers will help with cooling and also provide a slight amount of front-end downforce as well to help compensate.
More major changes for the front are a bit more difficult, since this is where a lot of the structure required for crash protection on the street is.  If I were to go full racecar though I'd be redoing the entire front structure which would be able to cut quite a bit of weight, but I'd also need to fully cage out the car including building a sub-cage for the engine bay if I did that.  We're not quite there yet.  I could move the lightweight battery to the trunk though which would also help with balance.
While not as far into the front, I am planning on removing the stock seats and seat airbags, jumpering them out, and installing a harness bar and two lightweight (carbon kevlar) race buckets with harnesses.  I may get a custom half-cage fabbed for me locally instead of the harness bar.  I'm still evaluating my options because I want to keep the car street legal and safe for highway use, which in Texas means that I cannot wear a helmet while driving on public roads while in an enclosed space.  If I can't wear a helmet, that means I'm not doing a full cage.  If I'm not doing a full cage that means I need to keep the front and side impact airbags.  If I have to keep the airbags that cuts a lot of options for weight reduction in the front.  Since I don't like the idea of my head looking like a watermelon during a Gallagher show because an illegal immigrant love-taps me on the freeway, caging the car out and not wearing a helmet to drive on the street is a complete non-option.  Unfortunately that's a South Texas reality.  So, the only way I cage it out is if I go track-only and buy another car for use on the street.

Howdy All,
You've probably seen my posts on the Facebook group, I also have a build thread over on FT86 Club Forums.  I have a 2017 Subaru BRZ in Crystal White Pearl purchased new off the lot in December 2017 that I've been building for the purpose of driving on track and on the back country roads here in South Texas.  There's some fantastic twisty roads here in Texas once you get a few hours outside of the city that deserve a properly built sports coupe.  I'm also lucky that South Texas is home to multiple well maintained road tracks, including Circuit of the Americas.  Typical country roads here are 2-lane state or county highways with 70mph speed limits and 25-30mph caution speed rated corners, great fun for hooning.
My upgrade plan is intended to keep the car looking as stock as possible externally as limited by required modification for aerodynamics and weight reduction.  I'd like it to be a bit of a sleeper, even after we get the power adders.  There will be no stickers or stupid huge vinyl banners on this car

Thanks for welcoming this Yank into your UK-focused group.  Cheers

Welcome to the club! Saw your thread on US forum . Your mods coming along nicely.

I have a 2017 auto GT86, since last June, interesting to compare mods.

I would probably say most notable difference for me was NA tune (change in manifold, thats header for you, right?, and remap) - torque dip is gone, more fun on track as well.

Then tyres (I have Mps4 as you but GramLights rather than Volks), then Bbk (I have on front only).

For track adjustable coilovers (I have Tein Flex As) are nice to have, but I wouldn't think of them as a must, particularly as I understand BRZ suspension in 2017/ 2018 is somewhat stiffer anyway.

FD replacement was highly recommended by quite a few people for auto, mine is currently being done (with few more power mods ), so cant provide personal experience comments yet.

Welcome aboard. I can see you've been busy with modifying. Interesting on the BBK , as I run a similar setup with the same calipers, but run 330mm discs which still fit under my 17's. Your discs look like they are stock sizes. Those pads seem noisy! I also run DS2500's, though mine are pretty quiet. 
Any plans for an exhaust or exhaust manifold? The manifold reaps the biggest gains along with a remap. Also I'm guessing suspension is on the list, that makes a big difference also. 
Also you could shorten the final drive on the auto to bring it closer to the manual which will aid acceleration. 
 

loving the attention to weight saving, what did you have in the boot that was 43.6lbs?

Welcome! Your white BRZ looks just like mine - same model year. I love your attention to detail, too. Nice work so far.
My sister lives west of Houston (Richmond) and I know those back roads a little, especially the drive to Brazos Bend State Park to see the alligators. Unfortunately, it's always been in rentals. Oh well!

Just got my new 2017 BRZ Limited yesterday.  Here's me picking it up at the dealership:
