***EDIT, for a brief intro on myself please view my intro thread and or my profile ' about me' section, link for intro at the bottom of this post   Hey guys! Welcome to the build thread of the BRZ that has already had its fair share of mods.
Some of you know the car already, others don't.
The info you'd like is due to follow.
The Basics; 2015, 15' reg Subaru BRZ Manual Stupidly Modified for a new car Previous owner brought the car new for £26,000 in march 2015 from subaru, then within a week of running it in and tracking it once, he took it to Knight Racer and spent £25,000 on it in modifications If it came out of the factory making some of the crack, creaks, crunches, groans and vibrations it does after all of these modifications it'd be handed back to the manufacturer, and the factory it came from would be condemned It's been built as a track weapon, so its flashy colour spray job is tatty, and as the above, it makes its fair share of funny noises I'm new to the seriously modified car scene, I've followed it with a passion, being a born and bred petrol head, super-car salesman, and now crash test technician, cars are pretty much my life. Now I'm going to attempt to list the modifications to the best of my knowledge and receipt pile, things may be missed, but I can tell you it's going to be long so apologies if you can here for a casual look!

The Modifications; Engine- Litchfield Spec-S Kit (Rotrex centrifugal supercharger, high-flow low pressure drop intercooler, mandrel-bent hard pipes, Litchfield Cold Air Induction kit, Ecutek software mapped on Litchfields Dyno) KR (KnightRacer) overhaul of the above kit, pushing 312 bhp rather than the 250-270 from Litchfield, this includes;  KR Exhaust Manifold & KR sports cat (2.5"), Milltek cat back, KR custom one-off remap = more aggressive ignition timing, higher boost and fuelling set up to perfection. Transmission- Competition Stage 3/4 (not sure which, all I know is that it was upgraded from its stage 2) Clutch. Lightened and balanced flywheel Brakes- Front =D2 6-pot 330mm big brake conversion Rear = D2 4-pot 330mm big brake conversion Suspension- Tein Flex-Z coilover kit ( set up by KR, -40mm) Tein Electronic Damping Force Controller KR carbon front upper strut brace KR front strut brace KR rear strut brace Wheels & Rubber- 8 x 18" Mak Highland alloys   225/40/18 Yokohama Prada Tyres 20mm spacers all around Interior- Carbon steering wheel cover Factory SE seats (not a modification but they're awesome so not needed to be) KR rear brace ( people say its a cage but it isn't, just looks like its trying to be! ) that also doubles up as a harness bar Sabelt 4 point harnesses Rear carbon fibre seat replacement panel Dry carbon compartment covers Dry Carbon Head Unit cover Carbon fibre door top panels Carbon centre vent surrounds Carbon Window Surrounds Carbon instrument cluster cover Exterior- Carbon KR Varis Style Front Lip Carbon Seibon Bonnet Carbon Rear splitter/ bumper Carbon Seibon rear AG style spoiler Carbon Seibon side skirts Carbon KR modified Seibon front Fenders Carbon roof cover Full Respray in TVR Candy Red by KR  Aaaaannnndddd a smacking great receipt for the labour haha! (around 1100 hours! yes! That isnt a typo! One Thousand and One hours of fitting, adjusting, setting up, spraying, tuning, and some more adjusting and tuning and cutting and bolting)
  So that sums up the modifications done by KnightRacer and the previous owner.
Now me being an enthusiast decided than as they know the car so well I still take it to them for the work I have had done even though its a 120 mile round trip.
In the nearly 2 weeks I've had the car I've done 1300 miles and its apparent that this car has be built well. The spray job isnt perfect, that because corners were cut to have it done in time for a magazine feature. This means that paint is thinner one some edges, and the cars original silver can be seen in a few spots. It's chipped, and scuffed, but that is because this car has been used! It isn't just a mean looking carbon clad trailer queen. It is as capable as it looks! And as with the previous owner that built this car, It is my daily.
This is the fun part for me. This car has had no expense spared in the build to this point, and it wont have with me either, it's just going to be a slow climb as I am only 20, and I have bills, a girlfriend, and a dog to look after!

The List Of Modifications That I Have Planned- Custom one off carbon Rocket Bunny kit Japspeed exhaust valve following the above, some deep concave rotiform black LHR's Big Bad Evil looking rear wing Custom made one off Carbon Front Bumper (I've tried a few companies but none will do it so far, message me if you know anyone who might) Respray ( maybe Audi Nardo Gray) Status Racing Ring GT-X Black Ultra suede with red stitching and red carbon fibre shell x2 Body Guard Paint Protection Film on all carbon pieces Front Carbon Cannards Rear Carbon Cannards Rear over th top diffusers Full Roll Cage Either Full Air Suspension or the mega Bc racing coilovers with Stance Parts Aircups  black rubber seal for top of bumper edge/ bumper and fender panel gap due aftermarket parts never being as good a fit as OEM this happens.   And there we have it for now!
The car is fast, light, incredibly loud, very very responsive, horrible in traffic, and has a horrid clutch that i'm just getting used to after 1000 miles, and considering how low and aggressive it is, the ride is actually really smooth and once you've pulled off the gear changes are awesome!
 ****
Everything crossed off the list will have a post written about it in the thread eventually as it has been done under my ownership, i'll just edit this initial post and post a reply saying updated.

Enjoy these pictures, any questions you have I'm happy to answer!
Thanks for reading this far !      ***** UPDATE #1 So, as mentioned above, for every item crossed off of the list, there shall be an update written about it. The Japspeed 2.5" Exhaust Valve.....  Was it worth the money? 
No How long did it take to fit?
As I was new to the BRZ I didn't want to do anything to it myself, I ordered the part through KnightRacer and got them to fit the part, They thought it'd take 3 hours to fit MAX, but it ended up taking around 5 because of how rigid the part was, and running the cable for the trigger was a Knightmare (forgive the pun). Thankfully because Albert ( the owner of KR) understands that I'm passionate about the car, and the fact that he really likes this car, he only charged me for half of the labour.

Does the Valve work or make a difference?
Nope. Not in the slightest.
It is fitted correctly, everything is where it should be, but it would seem either the switch doesn't work or the exhaust pressure is stronger than the spring on the valve, so I essentially brought a £140 valve for nothing. Advice?
Avoid.
It was such a faff that Albert has removed the part from the KR catalogue and filed a complaint to Japspeed. The Valve is the silver part at the exhaust flange Update #1.5
More problems caused by the 2.5" Japspeed Exhaust Valve DO NOT BUY THIS VALVE IT IS NOTHING BUT A PROBLEM So I've noticed an occasional slapping sound when driving recently, not enough to make me stop the car, but enough for it to be a concern....
Turns out the added width of the valve has forced my back-box tight on its hangers, not allowing it to move back, so now the front of my exhaust ( manifold and downpipe ) have no free movement.
This has resulted in my exhaust slapping against a metal cross member behind my cooling fans when the engine is under a certain load, when pulling off slightly wrong, when going down a road that is too bumpy, or turning left and pulling off.
I'm going to remove the valve on Saturday, unless knightracer want to try and make it work properly. At first I thought the above was a ball-joint, if you'd like an idea on how it sounded, however it is too intermittent to be suspension/steering related , and I managed to get the wheel off on Sunday for a proper look, it was a struggle but with some persuasion I can get it to co-operate  (see below)
