  1. I've had to bin discs on more than one occasion due to uneven pad transfer (not on my Lotus), and believe me I tried everything from "normal" road braking (cold) for hundreds of miles, to all-out thermal assault! There's a good article here:
  2. Vibration is more likely to be the result of an uneven transfer layer, rather than the disc warping, and is quite common when changing pad make/compounds.
  3. I used this process - it worked fine, but this was on new discs that had no previous transfer layer (of a different pad material, for example): Whilst bedding, brake applications should be consistent and using constant pedal effort, which is progressively increased throughout the procedure. 5 light snubs*, light pedal application: 50mph – 30mph 5 medium snubs, medium pedal application: 70mph – 40mph 3 hard snubs, hard pedal application (no ABS activation): 100+mph – 30mph** Cool down period – 5 mile run with very little brake (Do not sit at side of road with foot r

  5. Thanks Bibs - worked a treat. Unfortunately, I made the mistake of running this past my other half and it seems I've been having far too much fun of late, and have thus been ordered back to my life of toil and drudgery at the weekend.
  6. The "Display Information" link does not work for me. I get this error message: Sorry, there is a problem The page you are trying to access is not available for your account. Error code: 2C171/1 Just wanted some further information before making a decision. Display Information - Fast Car Festival.pdf
  7. Monday 25th July - heading South at 5:30pm-ish, and looking mean in it's black on black regalia. I was in the Disco with mountain bikes on the back heading North. Anyone on here?
  8. Sorry - been away from electronic devices, and on my mountain bike for a couple of days - which was blissful (when not trying to get off and crawl at 20mph!). There can be no reason for a change of width to the front tyres causing the car to pull to one side. Alignment for sure. Not sure why this would manifest itself upon a change of wheels/tyres though. What happened?
  9. ZZR's are not available in the standard (Corsa/Trofeo) front sizes, the closest is the 215/40/17as you point out. This is slightly wider (fits the rim better), and nominally has a slightly lower rolling radius due to the profile reduction not being quite offset by the increase in width. For a 40 profile tyre, the ideal width in terms of matching the original rolling radius would be 230 but as no such size is made, a 225/40/17 would be a better replacement for a 205/45/17, and would be ok on the 7.5" wide rim. However I can't find a track-oriented tyre in that size. The turn-in is sharper
  10. Blimey! - Everyone's at it! Just to remind folk what proper tyres look like :
  11. It will be fantastic to get your feedback - it's great news for all of us that there are more tyre options opening up. I go with these recommendations from Avon: Minimum cold starting pressure: 22psi (This is the pressure the tyre is set to prior to a session/ heat cycle). Running any lower than this could potentially damage the tyres sidewall construction. Avon Motorsport does not recommend specific starting pressures. This is due to the variables involved (i.e. track conditions, track and ambient temperatures, circuit layout, session length, driving characteristics).
  12. Just under £800 for a set of Avons fitted. I got 4k miles from a pair of rear Corsa's on the road (only did 1 track day on them), so however you look at it, rear tyres are going to be a fairly constant consumable. All of the tyre options are relatively inexpensive and like all things dynamics related it's about finding a compromise you're happy with: If you want exceptional dry grip you'll pay the price with wear rate I guess (and water clearing capabilities). I'd rather base my choices on performance (grip), feel, and on-limit behaviour than secondary ride, cost and longevity but as I do
  13. 2nd photo must have been shot using the mother of all selfie-sticks.
  14. It would either take almighty reviews, or a decent cost differential to prise me away from Avon ZZR's - they generate really strong grip but are nonetheless very benign and predictable at the limit of adhesion. Must admit I do like the appearance of the Toyo's though, so I'm keen to hear the opinions of the early adopters among us...
  15. I feel your pain David - quite literally, having managed an almost identical hedge trimming mishap a couple of years ago. They don't heal too neat - especially when you give up waiting in A&E, and decide to go to bed with a bit of a bandage on your leg only to wake up in the early hours with the situation in need of re-assessment! Apparently such wounds are best sutured quite quickly. You live and learn, and I now have a LOT of respect for that piece of machinery. I tell people it was a shark bite! Good luck, and heal well....
  16. Well done Robbie, and welcome. Wonderful car you've just bought. Keep us posted on your thoughts once you've had chance to have a decent drive in it...
  17. I see - good on you! I'm on ZZR's now too, and absolutely love them - the car feels much more keyed-in to the road surface, and there's certainly more front-end bite and alacrity. The Corsa's are a fantastic all-round tyre though - absolutely fine on track (so long as pressures are watched closely) and incredible in standing water. In the dry though, I love the way the ZZR's make the car feel limpet-like.
  18. They can squeal a tad at normal road temperatures, but I've never used a track-biased pad that doesn't. I'm probably in the minority here, and admittedly slightly unhinged, but I actually quite like the noise. In terms of performance - they're very very good on the road, but can be a little grabby/snatchy when fine modulation is required at very low speeds (but that's just as likely my complete lack of deftness as any failing on behalf of the brake pads!) Just to clarify, the noise is only really present in town driving scenarios - 30mph or less, traffic-light to traffic-light stop/start
  19. I guess the higher grip levels of the Cup (tyres, geo, springs/dampers, less mass) ultimately mean less reliance on intervention from electrickery. The PF08's came recommended by a chap who runs 6 or 7 Exige's in the Lotus Cup - he was a couple of garages down from me last time I was at Donington. Having just done a quick search based on my sketchy memory of the company name, I believe it was Track-Group.
  20. Changing the pads (and discs for that matter) is so quick and easy, it's silly paying someone else to do it, unless you really don't like getting your hands dirty. I am also now running Performance Friction 08 pads and I like them better than the Pagid RS14's - which in my hands at least (or foot!) get seriously grumbly when very hot, especially on the cross-drilled discs, and you have to really watch for uneven transfer. I'd love to try RS29's on the Exige - my old favourite, but it has to be said I used them on much heavier machinery in the past so I'm not sure how their characteristics woul
  21. Mother of god! That is just fantastic. The want reflex has certainly been triggered...
  22. I'm very jealous Dave - there's hardly a day that passes when I don't long to be in the Alps. Great pictures. What was the general reaction to the Exige? I imagine there are not too many of them around in those parts. For anyone interested in doing likewise here's a snippet from my route from a few years ago... Day 2: North of Lyon to Monaco via Route Napoleon, Cannes, and the Promenade des Anglais in Nice: Day 3: Monaco to Val D'Isere via Col de Turini, Col de la Bonnette, Col de Galibier and Co
  23. In what type of event were you competing? Your car looks fantastic by the way!
  24. The brain-dead automotive equivalent of mouth breathing shufflers who use obliviousness as a default state-of-being to get them through their waking hours. And, more pertinently, their commute to and from the premises of whatever unfortunate and short-sighted employer who saw fit to empower them with a task worth paying for. I finally understand the origins and thinking behind the "Speed kills" brainwashing campaign: On the evidence of my drive home this evening a huge proportion of the "driving" population, who presumably somehow managed to fluke a pass on their driving test at the 127th atte
