Either it's me or MK roads, every car I've had has warped a set of discs at least once, these are pretty badly lipped too so I was expecting to have to replace them this summer anyway, was a little cheeky chucking another set of pads in. I think the constant 70mph-0-70-0 of roundabouts really doesn't help, as any more than 3 high speed stops kills most standard pads. If be very surprised if you have warped discs. Have you actually confirmed they are by checking runout? Ive done quite a few trackdays on the stock brakes and got them so hot the pads smeared pad compound unevenly all over the disc. The brakes judder a lot for the next 100 or so road miles and feels just like an old school warped disc when cars used to have non vented solid discs that could warp easily with uneven heat. Stock pads, especially if you have the soft ones fitted to reduce squeal, will melt relatively quickly. Share this post Link to post Share on other sites
Keethos 842 Report post Posted March 5, 2017 Is the smearing of pad compound visible? When I was at Oulton, I started to get a little bit of judder through the pedal at the start of a session, but as the session continued, the who car started to judder. Then after a cooling down, back on track and repeats, started off light and got progressively aggressive. Once the track started to dry out, I was on the brakes a bit harder which meant a lot less juddering...to the point that I could tell if it was the same juddering or just normal vibrations at that point.....any ideas?

surrey86 352 Report post Posted March 5, 2017 The oem pad smearing was visible on my discs yeah. I removed my front oem pads at 22k, expecting them to have loads left after reading here - and was surprised to find they were quite thin! If I'd have done another trackday on them it would have been an early finish to the day. 2 Ade and Keethos reacted to this Share this post Link to post Share on other sites
Ade 517 Report post Posted March 10, 2017 Sorry didnt see this. Yes pad smearing, if bad enough leaves lines on the discs and you can feel them by running your finger over the surface of the disc. Here's my stock disc after destroying project Mu HC800+ in two track days Share this post Link to post Share on other sites
alucardo 55 Report post Posted July 16, 2017 After my recent trackday the brand new 2500 and standard disk judder mainly down to deposits. Is there a way to clean this off or will normal breaking for a while clean this disk? Share this post Link to post Share on other sites
alucardo 55 Report post Posted July 16, 2017 So to follow on from my post above I have decided not to mess about and look at BBK and get one. The article below is an interesting one and at the moment the stoptech is favourite the 328. Can anyone confirm this fits under a standard alloy? Also looking at the Tarox kit aswellhttps://www.japspeed.co.uk/tarox-toyota-gt86-subaru-brz-326mm-front-big-brake-kit.htmlhttps://www.pointmeby.com/2016/09/24/which-big-brake-kit-bbk-should-you-get-for-the-brz-frs-gt86-86/ Share this post Link to post Share on other sites
Kodename47 446 Report post Posted July 16, 2017 I'd be surprised if it fits without a 10mm+ spacer on the wheels. Can you not get a template from the Tarox site to print and check? I know you should be able to on the StopTech one. Share this post Link to post Share on other sites
rob275 1817 Report post Posted July 16, 2017 They are the same size that I have so I can check with a stock alloy if they will fit. I'm fairly sure they do though... Share this post Link to post Share on other sites
Bfranklyn86 52 Report post Posted July 17, 2017 As rob says, this stoptech wont fit without spacers. AP racing designed a BBK that would just fit with stock wheel and no spacers, but they are pricey at 2.2k Share this post Link to post Share on other sites
alucardo 55 Report post Posted July 17, 2017 Not a fan of spacers. Are AP the only bit of kit that fits under stock wheels? Id rather retain dust boots aswell. Share this post Link to post Share on other sites
VAD17 479 Report post Posted July 17, 2017 What about Tarox? Rob had a good review. They are quite a bit cheaper. I am also considering BBK as my first mod on a new car. Planning for max 5-6 track days a year (wish could do more but fairly unlikely). Heard good words about AP Racing, so still undecided.

alucardo 55 Report post Posted July 17, 2017 I have emailed them to ask about their brake bias and whether they have dust boots. They seem like a good option as the brakes fit under standard rims according to the link above I posted. Share this post Link to post Share on other sites
Bfranklyn86 52 Report post Posted July 17, 2017 I can speak very highly of the AP racing ones, as I have them - great for road and track. Regarding the bias, I haven't noticed any difference in handling. Just much much better braking, and no squeal! However you could get the tarox brakes and a new set of wheels for the same price I would expect. Share this post Link to post Share on other sites
Rich 378 Report post Posted July 17, 2017 I'm not sure you could, Reyland Motorsport have AP brake kits for the GT86 for just under £1500, which is not much more than Tarox are asking. Share this post Link to post Share on other sites

Church 209 Report post Posted July 17, 2017 If track use is considered, i'd probably would get AP Essex Sprint kit. it won't just give higher heat capacity and lighter weight, but it's rotors & pads should last twice as long, letting save on wearables in long run. Also should be easy enough to get different vendors/compounds pads in that shape. I'm not that sure that if saving on wearables & common pad shape was high in priority list for many of other BBK kits. Otherwise i'd use stockers + airducts.

alucardo 55 Report post Posted July 17, 2017 Yeah I was looking at consumables aswell. It is mainly for road / track work (5-8 a year). I was using standard disks ds2500 and gt3 ducts on a Hot day and was braking quite hard and they just came apart. My considerations are: 1. Fit under standard wheels 2. Dust Boots 3. Brake Bias 4. Consumables AP are on my list but just looking round at others at the moment as AP are pricey. Share this post Link to post Share on other sites
TTR 509 Report post Posted July 17, 2017 Tbf DS2500's aren't an all out track pad Share this post Link to post Share on other sites
alucardo 55 Report post Posted July 17, 2017 Yep very true. However they are one of the pads that don't squeal like mad or chuck have a ton of dust everywhere. Every other pad that can do track and road do that. Having separate pads is the other option but consistently changing them in and out would get annoying. So thats why Im looking BBK's. 1 TTR reacted to this Share this post Link to post Share on other sites

Looks like your considerations and short list us just like my, but clearly you ve done more thinking and research .

Yup, Reyland use a wider caliper (CP5200) and a wider disc (28mm) compared to the "official" AP Kit that uses the CP6628 Caliper and a 26mm disc. Share this post Link to post Share on other sites
