R26 2-piece disk options

Discussion in 'Suspension, Brakes, Wheels & Tyres section' started by SonicUK, Dec 9, 2016.

  1. My 330mm godspeed discs have finally given up after some serious track-abuse over the last few weeks, so although im happy to get some more i through id prudent to look at alternatives.

    The cheapest option must be some replacement J-hook rotors to replace the cracked ones, but these seem to have mixed opinions vs AP or PFC.

    What are peoples thoughts, or any other options for 2-piece discs on the R26 with Brembo callipers? Preferably with links / costs.

    I'm not sure if its possible just get a pfc rotor and use the godspeed bell?

    Cheers!

  2. Get J-Hook ones from Reyland.
     
  3. Are those a personal recommendation? How come you'd go for those over the Godspeeds?
     
  4. Better quality as far as i know.
     
  5. last time i was up at godspeed there discs were actually AP blanks.. bit worrying the cracking though,
    id let them know whats happened.. they could well be interest to follow up..
     
  6. Godspeed no
    Reyland yes
    Speak to Martin at Reyland tell him you know Jd red Megane he will look after you.
    I live down the Rd from him and had 2 sets so far and have been amazing.
    Really would recommend Reyland

    Redland discs are just drilled out/machined OEM discs.

    If be speaking to AP or PF tbh.
     
  8. No worries I would of done the same before I tried them
     
  9. I think Performance Friction have a good reputation and a solid UK operation. I certainly will be switching to their 2-piece discs when my OEs are worn.
     
  10. Why would that be a bad thing? Ususally oem has better manufacturing.

    Not when you compare them to a proper rotor from the likes of AP/PFC.

    OEM stuff isn't usually designed to work well with high temperature and the abuse that track work requires. I know that some of the sizes of disc use a machined X5 disc. Hardly a motorsport spec item is it?
     
  12. They are indeed butchered x5 items. They used to be sent out in the boxes with the x5 part numbers on them.
     
  13. You would think.
    An x5 is dimensioned for hauling heavy stuff. It needs to be able to perform under heavy load and at long descents. Ie much bigger weight (12t including the trailor, or even empty car of 2 and some tons) and long braking times.
    Do you really think a track where heavy/hard and short braking times with a ton and a half car are present is worse then a 10-15min constant breaking?
    You would be very suprised non of the track discs would handle that load.
    Dont just simpy asume that the track ride is the worts load, insted learn a bit and then bash on something being bad.

  14. Lads take this advise or don't.
    Reyland Disks are as good as the top brands.
    Don't be fooled into thinking otherwise.

  15. Sonic take it from me the reyland disks are more then enough for a megane.
    Don't waste your money on the brands there is no need.
     
  16. Cheers for all the messages!

    I've exchanged a few emails with Martin at Reyland and he does the full 330mm kit with 2-piece floating for £690, which is only £60 cheaper than the Performance Friction kit. The 343mm is £740 all-in delivered.

    Godspeed haven't yet got back to me with prices for replacement rotors, but i was only considering this as a cost-effective option given i have the bells.
     
  17. To be honest are the oem disks any good?
    Ive always ran 2 piece disks even when I collect my 65 plate cup s I took them off due to me having reyland disks of my old 265?
     
  18. Hmm, there's some brand new Reyland ones on eBay, being sold by a Martin Hadland, for £535 - are these not the same 330mm ones he's quoting you £690 for?!
     
  19. The 330mm kit is £525 plus postage on their website???
     
  20. They are 2 piece but not floating, and that doesn't include delivery. Floating is an extra £150 on-top of the price, postage another £15.
     
  21. Ahh right yeah.
     
  22. PFC are updating their floating design to v3 so these aren't available, and nobody can provide me with a date, so I've gone for the 343mm Reyland with floating after Martin did me a good deal, so we'll see how they get on!

    I'm going to try and fit some ducting as well from the fog light holes to provide extra cooling as the XP12s create some serious heat when used properly, although I understand this is awkward on the drivers side due to space constraints!
     
  23. Is you change your washer bottle for a R26R one they are half the size so it creates more space

  24. I have the V3 versions on mine.
     
  25. Apparently they haven't even designed or manufactured the R26 discs with v3 yet so that's quite impressive!
     
  26. Fantastic thanks, i'll get hold of one. Very useful to know!
     
  27. I have the V3 versions on mine.

    Why is floating disk so important?
     
  29. It's true, he does lol! Bespoke but still PFC rotors and v3 setup :yum:

  30. Sonic i must of dreamt it then. No need for such a curt reply chap but seeing as you're calling me out...

  31. No need to be so defensive, chap, I simply said if you've got them when all 8 UK distributors and PFC themselves have told me they're not available yet, not even designed or manufactured yet for the mk2 Meg and with no date when they can be supplied, then it is quite impressive that you have a set. Which part of that is wrong?

    Not everybody on the internet it out to get you, you know!
     
  32. Even if you don't go for the V3 which would require a new bell I'd still plumb for AP or PF. By the sounds of it you give the brakes some stick so worth the upgrade. I'll be taking mine off the car this weekend to put brembo hc and ds1.11 back on.
     
  33. Yes they do get some serious abuse!

    The Godspeed kit came on the car when I bought it earlier this year and lasted a set of XP10's, but barely survived the run-in process when trying the 12's, and hence looking at alternatives.

    I've ordered the Reyland setup so I'm interested to see how they get on, but for sure I wouldn't expect it to be up to the standard of the PFC setup. Had I have known it was possible to acquire them I likely would have leant more in that direction, even for a premium.

    How come you're reverting back to HC out of interest?

    Thanks for the link.

    Sorry I should have rephrased the question. Personally I don't think you need them, I raced in a championship like many in the UK that had as part of its rule set regulations that meant one couldn't have floating disks. The Porsche Club championship I was in required standard disks even after they went to Pirelli slicks from 2013 on, these standard disks and calipers on many cars were no bigger or fancy than on our Meganes but everyone had the best pads they could afford (Pagid RS29 I loved) and plenty of cooling ducting. Having said that though I hated running slicks on my car as with the stock disks and pad size even stamping the pedal down as hard I could I couldn't get the ABS to kick in (organisers wouldn't change the rules to allow my car to run bigger Porsche calipers which became a bit of piss take trying to compete against newer cars with more power and bigger brakes). Still though never once overheated the brakes to the point the pedal went soft, despite always boiling the fluid out of the reservoir. On our Meganes many people driving on track days seem to run into brake overheating problems which tells me they need to be looking at getting cooling air into the disks before spending loads of money on fancy setups.

    Having said all that I always wanted more braking performance, car pulled 1.5g in the corners but could never get over 1.1g on the brakes and seemed to be limited by the stock ancient ABS system and other components we had to run. Still though looking at your picture you have cracked the disk probably from running it so hot and its likely IMHO that without getting cooling into the brakes you will just keep chewing through disks.

  35. Only going back to them over winter as it's my daily. So pointless running expensive pads and discs on a daily commute so they'll be back on when the weather picks up and track days are booked.

    Standard wheels with winter tyres etc etc will go back on also.
     
  36. what HJH says, cooling over upgrading
     
  37. Has anyone had any success with brake ducting on the MK2 Megane, in the form of deflector plates and piping.
     
  38. Great info, thanks!

    I actually don't think the cooling on the meg is that bad, i mean compared to the Golf R i've recently made some brake upgrades to it's fantastic!

    I'm running RBF660 fluid, previously with XP10 pads and now XP12 as a comparison, and obviously the discs have cracked badly. This could be partly down to wear, and a very hard but awesome Silverstone day just a few days before the discs cracked and which saw out the XP10's so i fitted the XP12, but unequivocally they cracked due to heat.

    So i see the new discs as less of an upgrade, more as a necessity just to replace the damaged ones. My rears for example are standard solid un-grooved discs!

    I also feel the need to always have more braking capability. On my Audi S2 i've been through several iterations of brake upgrades as i wanted to be able to brake so had the ABS would kick in if needed, and i've ended up with a rather large front setup with the 8-pot brembo's from the R8/Gallardo which have 4-pads per calliper, and a Porsche/Brembo 4-pot monoblock rear conversion with separate handbrake, and which are larger than the OEM fronts were :smiley: The benefit of this is that it can do lap-after-lap-after-lap of the 'ring or Spa with absolutely zero braking reduction.

    On the R26 i absolutely feel the need to try and add extra cooling in addition to the new discs...

    Ah indeed, makes perfect sense. Fortunately my R26 is a dedicated track slag :smilingimp:

    From looking around it seems lots of people have discussed this and even attempted it, but very little has resulted. There doesn't seem to be any easy way to provide additional cooling due to the hub-surround setup and the large water bottle blocking the route of any ducting from the fogs on the offside.

    I think what i'm going to do, unless there's any further ideas, is to fit the R26.R water bottle as suggested above, or one small enough to warrant some ducting to run from the front fog inlets, and then cut through the arch liners and fix to the wishbones or somewhere near pointing in the general direction of the hub and discs... it'd be great to be much more accurate but without some kind of mount to force the air into the centre of the disc i'm not sure what else can be done.
