    For HARD driving?  Were they not HARD driving? Seemed reasonably committed to me :)

    You know the first circuit is Zolder right? 

    2nd vid 8:28 on that simple windy road is very good. 

    These people who can't drive on standard brakes...:D

    8:28 is a good lap but isnt that fast for a car of the spec. But its not down the brakes iv been quicker on STOCK CALLIPERS no problem, it the fleshy bit between the steering wheel and the seat the only thing slowing it down there.  You see that STOCK CALLIPERS aren't the limiting factor, on a track that isnt that demanding on brakes.

    The ring is very easy on pads, just throwing it out there. 

    Good pads and a stock calliper will work just fine for most agreed by most here, for HARD driving to achieve a consistent and repeatable pedal throughout the day a BBK is the most sustainable way forward.

    It's a shame you hadn't tried something better than a hybrid, road biased pad then to be able to give an accurate comparison.

    Certainly road pads and stock calipers overheat quite quickly when used on track. 

    Admittedly I have a charged car. However I started with DS2500 pads on stock callipers. 2 laps of donny and they were shot so much fade! Pedal always felt wooden from cold. I then upped the game to carbotech XP10 pads, I removed the disc stone guards and put on GT3 cooling ducts. These were night and day compared to the DS2500, bite was always there and was consistent which made modulation easy. I didn't get any fade when I did brands or Cadwell ect, the tyres would give up before the brakes did! However when it came to man sized stops I was getting fade, this was on the Nurburging GP into T1 hairpin  which was the biggest brake in F1, and Rockingham T1, when you had come off the banking into the hairpin. The common theme is a hairpin big speed 150mph to 30ish? Could have lived with this perhaps but I got through them fast, they did not last long at all. We are talking 4 track days. These pads arent cheap and I didnt see that as sustainable.....

    For a spot of context:

    The car I came from before the GT86 was a MK3 MX5. Even more track biased. The MX5 was on stock discs and callipers, and Carbotech XP8 pads. This car was around 1100kg, and 190 HP at the fly. It used pretty much the same size disc as the GT86. 290mm x 24mm, the MX5 was a single pot slider the GT86 a twin pot slider.

    The MX5 ran Carbotech XP8 pads, and did a complete 10 track day season about 200 track miles per day, and never suffered fade and did a season on a single set of pads.

    So the 86 is 150-200kg heavier than the MX5, and has another 70hp? and its was running a very similar sized disc and pad which is going to have a similar thermal capacity. Therefore to gain more thermal capacity a BBK is the only way. This would lead to no fade, greater consistency and lower pad wear. Yes I could have gone for a higher rated pad, it may have stopped the fade, however it was going to generate more heat and probably wear out as quick if not quicker.

    I bit the bullet and for the Rayland BBK, Cp9200 calliper and a 330mm disc. I am using a Mintex F4R pad, these are fairly aggressive but cost around £100 so nice and cheap. The brake fade is gone, the consistency is spot on every time making modulation easy, they look great, the wear is low. Oh and the POWER. These rip your face off when you throw out the anker, its my favourite bit of the car. So you can now stop faster, with no fade lap after lap until the tyres give up.

    Best track day upgrade for the car!! I would not bother if your not a keen track day goer though. If you do 1 or 2 a year for fun and your not "fast" put a decent set of pads on take the disc stone guards off and put some £20 GT3 ducts on and enjoy.

    No matter what brakes you have all ways use decent fluid, you do not want to boil it and end up with no brakes!!! I use RBF600, and always bleed a pedals worth out the calliper when I have the wheels off as thats where its going to boil.

    As an aside I have been told the following;

    The R1234y gas that is in the earlier cars, while being much more friendly to the ozone layer when it leaks out is, perversely, more likely to leak out due to it’s molecule size   🤪

    The older, less ozone friendly, R134 fitted to some of the later cars is less likely to leak.

    The aircon compressor on the my 2012 car is labelled as being suitable for both R1234 and R 134.

    R134 is cheaper.

    Id your aircon doesn’t work it’s a calculation for you and continence.......

     

    I mean its not because its illegal for one, but even if you can find someone to do it, you need to change the AC filling ports as the are different for each kind of gas.

     

    I got my AC R1234yf done at toyota for £70 last month.

    your problem is this car has a huge manifold thats not far off the same size the under tray. Couple that with every seal on engine being a liquid gasket and not a proper one little leaks are common nearly all catch the manifold and cause a smell. 

    Id suggest getting a mirror and stick and looking round the front chain cover they often leak there.

    Id of said you have done well after 15+ trackdays. First photo looks to show pad witness. Where the car as been sat and the pads eat into the discs. I usually pop my pads out if the car sits over winter for example. You can help minimise this by making sure you dry off the brakes before letting it sit. Ie after washing it, just take it for a short run and ride the brakes.

    So after 4.5 years of ownership I said goodbye to the GT86. After all this time I cannot think of a single day I did not enjoy the car even after taking all the parts off the car and putting back to standard it just reminded me of what a great car it was before I started tweaking it. I'm luckey that my wife drives a Giallo so if I ever miss it I can take that for a spin and experience one of the great cars again.

    I replaced my gt86 with a not holy unexpected:

    981 Cayman S

    Once I have done a few miles in it I will come back and add a comparison. 

    Have a good Christmas all.

    Happy Christmas to you too! Nice little present to yourself!

    Love to hear an on going comparison between new and old when you get some more seat time!

    Here you go and in case you wondering what happened :(

    I braked in enough time but the crap Yokohama AD08R's on my car lost traction and then went sailing off the track into the Gravel Pit !!

    I now have 5x New Kumho KU39's on order as am fed up going off the track with those crap tyres !! (spare wheel in the boot)

    Driven 53 Track Days in the GT86 this was the first time ever I went off the track and had to be rescued :angry: and other times I just been able to drive back on without help :)

     

     

    Shows your trying! Thats the main thing! If you drive home that's the ultimate prize. Wonder if your AD08R's have just been heat cycled to many times and they have gone hard. I was on RSR and they were interesting on the first few sessions but I would say no worse than the MPSS I was on last year.

    Cheers guys :)

    Never driven one before but i'm quite enjoying it. I've not had a car that loves to be revved right out through the range before so the driving home from work through the twisty roads of the sussex dyke is always fun

    Henfield! I work in small dole. I look forward to seeing it about. Always use the dyke road and Horn lane.
