  1. Yep! What i heard I'd that Federal have two manufacturing plants, one for 'race' tyres and one for road tyres. There were a load made at the race plant then production issues meant later ones were made at the road plant, meaning different compound and less tight tolerances... These were cheaper to make hence all the discount places chopping them out cheap. Half tempted to try and find a 'proper' set, will gain me quite a lot of time for no effort!
  2. Means it's working well.
  3. Alex, modifications are very limited, yeah. There's only one track all season where we use 5th gear, haha. All we can do for power is skim the head, cut valve angles and change the exhaust (but not the manifold), standard diff, standard gearbox, standard brakes (pads are 'free'), we all have the same shocks, wheels and tyres (more on that later), maximum camber limits, minimum ride height of 100mm, minimum weight of 970kg... makes for close racing and less about who has the fattest wallet (to an extent). Yeah, I try to keep it smooth to protect the tyres. They go off towards the end of the race - everyone finds the same and lap times typically go up about 1 second per minute (if that makes sense). The person in the yellow car won the series last year and by getting past her in that race it puts me level on points with her so far this season... so maybe that's why I was pushing a bit 'too hard' and getting tense at the end (plus combined with the tyres giving up makes the car get a bit loose giving the impression of wrestling it around). I have a logger but encoding the video with the data takes ages so I don't bother any more, but speeds are pretty low - maximum all weekend was about 107 with a massive slipstream! G forces peak about 0.95 in braking and 1.3 for lateral. Tyres is a bit of a complicated subject at the moment - we generally only have one control tyre, which last season was Federal RSR 595s, but they were found to vary a LOT (like... 2-3s a lap) between batches so we have now switched to Nankang NS2-Rs. However, there's a year crossover for those who have stockpiled Federals to allow them to use them up, meaning we have cars on different tyres. They are pretty close in terms of lap time overall but some people find the Nankangs faster and others find them slower - all depends if you are comparing them to a 'good' Federal or a bad one! For example, I found about a second on the Nankangs over the Federals, but the person in the yellow car was 1-2s slower on the Nankangs. I can't wait til we're all back on the same tyres, at the moment it's a variable that shouldn't be there in single marque racing IMO.
  4. Why? Echo make more of their own parts than most (as in, they have their own manufacturing facility) but certainly won't be making those bars in house, they'll probably be made in the same place as *insert your most trusted carbon bar brand here *
  5. That's one of the lowest amounts of force the steerer will see, stop stressing and just ride them They are designed to have some flex, as all parts are, else they will break.
  6. That's what she said. This is the only one we can use: http://www.ebay.com/itm/Mazda-Miata-MX-5-OEM-1990-1997-NA-Front-Bottom-Lip-Air-Dam-Spoiler-R-Package-USA-/181254774020?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a33a05d04&vxp=mtr No home jobs allowed
  7. It's only a little baby one: https://www.facebook.com/photo.php?fbid=435903369887981&set=t.512661146&type=1&theater
  8. No worries, thought you'd find it interesting! Yeah, yours is kinda like #4 I guess, which isn't much different to 6 anyway... certainly a huge improvement over nothing We are allowed a small splitter but not many use them and nobody seems to have done any testing / maths behind it. I fitted one for the last round and found a pretty amazing difference... The photo below shows speed traces from a track day with the car having exactly the same setup, and the qualifying session after having fitted the splitter and undertray. The blue and yellow lines are the track day, the pink and red are the quali session (picked a quali session as there was no slipstreaming to throw off the readings): The numbers at the top of the vertical line are the speeds in mph, so above ~85mph it really makes a difference! The time saved is nearly 0.3s just on the main back straight at Anglesey, and more importantly the extra speed gained gives a much better chance of sticking in the slipstream of - and passing - the cars with, er, slightly more power than is allowed. Pretty chuffed with that!
  9. Yes, need correct torque and threadlock - and alloy bolts aren't a good idea for rotors.
  10. Ah, cheers Nick, glad you enjoyed it! Something that is sort of relevant to your post... I was checking out aero stuff for the Mazda and found this link: http://hanchagroup.wordpress.com/2013/01/29/splitter-or-air-dam-which-design-is-best/ Seems your barge board and splitter combo is going to be pretty effective
  11. The issue was loose rotor bolts in that case - should have mentioned it in the first post!
  12. Sounds like pads moving in caliper as you said.
  13. My weekend... It's a pretty long video, but the best bits are at Rocket on the first lap of race 1 at 0:50, a very slippery encounter with Matt from 3:58 onwards, race 2 start at 10:13, Rob grass-tracking at 14:34, race 3 start at 17:09, overtaking at 18:37, 19:18 and 20:00, and then a 10 minute position-swapping tussle with Amy from 20:50 til the end of the video, which includes overtakes at 23:23, 25:57, 26:33, 27:34 and 29:10.
  14. Basically the Cuerden Valley Park show is coming around again and Joe's asked me to check if there's any interest in having a trials setup again? It takes a lot of work to set the stuff up (a couple of days) and only a few people turned up last year. We appreciate it is very weather dependent, but who's up for coming? Cheers, Adam
  15. BB shell on frame been faced?
  16. First result on Google images... http://www.bugatti.com/pages/72/bildspalte/acceleration01.jpg Is this primary school or a degree?
  17. No really, they didn't If you're trying to use barbed fittings with hose made for disc brakes, it won't work (safely). If you are buying all the relevant fittings to attach said hose to the brake properly then it will work, but be expensive and the brake will feel sluggish. If you desperately want coloured hoses, Google heatshrink.
  18. You're using too much torque.
