    That's a great compliment, thanks. Maybe one day try it in the dry with slicks. That's totally another ball game.

    Its entirely justified. Maybe im naive but i was not expecting anything like that. I actually asked him to slow down lol. Not my most macho moment pmsl!!
    Very keen to get my car ready to track and would love to see you guys on a trackday. Try and get some vids made up to demonstate the difference .

    Was good fun, cheers for popping round mate. It's shame it was wet really! It's more impressive in the dry when you can really work the brakes properly :)

    Nice to put a face to a name and have a good chat over a cup of tea :racer:

    Because I'm so rock n roll, this afternoon I fixed my broken window clip:

    Only been broken a year, so it's really rather nice to be able to open it again!

    I'm not too bad at modifying cars, engines, turbos, suspension etc etc, all stuff I love.

    but little fiddly things like window clips and that stuff? it's just low priority!

    it is nice to be able to drive along with the window down though, AND to be able to put it back up again!

    I drive it when I'm bored :laugh:

    Really cannot wait to get back out on track in 3 weeks time :)

    Hopefully will have a further development on the braking front also, but still waiting for that to all come together :)

    Brakes so far: amazing! really love them. initial bite is fantastic, and pedal feel is just right too. i've tried to get them to fade on the road and not managed it, so initial thoughts are very good indeed.

    real test will be at Bedford in 3 weeks time though, then we'll find out what they're really like :)

    Did you ever weigh the car before the strip. Im thinking of going to my local scrappy to get a before weight.would love to know exactly what mine weighs at the moment. Also you may have convinced me to attempt the seats myself (gulp)

    1240kg with the stock 16'' spare wheel mate, 1220kg without the stock spare.

    Fully stripped with monaco pro seats and no interior it was once down to 1060kg.

    Roll cage, fire extinguisher, bigger safer seats, bigger turbo, brakes, intercooler, meth, arb's etc etc have added a total of about 70Kg to that bringing it up to around 1130kg as it stands now.

    First time ever mate, been meaning to do Bedford for a while!

    I think I'd be happy with somewhere below 3 minutes, but that's a random guess from a quick google. obviously you don't go to trackdays to time things :laugh:

    How did you get on with your ebay steering wheel mate. I was meant to ask you last weekend. I also noticed you now have a flat one opposed to dished. Did you not get on with that type?


    Also whats the next trick up your sleeves? Anything planned?
    You guys must be running out of things you can improve lol

    To be honest mate I got on just fine with the ebay steering wheel. The first one I had lasted a few years, and it was really nice. I bought a second one off Jardo purely for looks as it had red stitching, but sadly it was bent in the accident, but that's no great surprise.

    it wasn't anything like teh cheap nasty flexy Nardi ones as seen in the driftworks demo video, it was fairly solid and well made, and only deformed very slightly in the high speed impact.

    We decided to fit a removable boss when we added the bigger seats to aid getting in and out, and the boss spaced the wheel back 60mm.

    the 60mm snap off boss AND the 3'' dished wheel was too much, so we had to change to a flat wheel to accomodate the boss. otherwise we'd still have the dished wheel as it feels really nice having the wheel so close :)

    Further plans include another minor brake development on the current setup, details to follow shortly I hope, and testing out some full race wets that I'm going to have mounted to my TT rims so we can go play on wet trackdays too :)

    Aside from that, just driving it!

    Better brakes. Yeh i did think to myself after you hit the brakes.
    " im dizzy, but not dizzy enough"
    That cars simply mad. The more i think about it the more i realise it is mental fast.
    Just so flat in the corners. Seriously stable. Taking my car out tonight which will now be a massive dissapointment lol

    Got a few hunderd miles on the AP brakes now, and we're absolutely LOVING them. they're just fantastic, and soon to be even better ;)

    Today we had our Pirelli wets fitted to my old TT rims (that Jamie managed to ruin :sob: )

    These are Pirelli WH 245-620 race wets.

    They really are rather stupidly good!

    Bring on the wet trackdays, we're ready!

    I asked Bill very politely, and he has kindly made some Ninja Death Stars for you to play with in the pits whilst I slave away working on the car:

    Yes, mores than adequate at the moment. Locks the wheels up very quickly if pedals only moderately pressed. With the new ninja floating bells the stopping power should be even better. Track testing is the only way to determine what works. Hard road use just does not get anyway near replication of track abuse.:readit:

    We'll be sticking with 330 or 335 Daz.

    The original plan was to go 343 and really push as big as possible, but the costs involved were just insane.

    By doing it this way, with these Bells from Bill we're able to 'float' our existing AP 330 x 28 rotors, as these run on a 12 x 8'' PCD.

    Then, in the future, when new rotors are required, we can upgrade to 335 x 32mm Hi-Spec rotors, and use a special shim to widen the caliper to accept the 32mm disc. This will retain the 8'' PCD and these bells, so the upgrade is done in 2 halves, making it much more managable on the wallet!

    Nothing you do is manageable on the wallet.
    Tbh if you can lock the wheels then surely no point in going bigger?
    What pad you aiming to use. I guess keeping these working at their optimum is more important.

    the key to big brakes is being able to NOT lock the wheels.

    even stock brakes can lock the wheels at 100mph with a hard stab of the pedal, the secret is in the modulation and feedback and feel you get from a big brake kit.

    With stock brakes, you get a set amount of retardation, that the tyres cope with easily, then you press a bit harder, and due to all sorts of issues with caliper flex and other things, you don't slow down any more, then the wheel locks up, and then you're not slowing down at all.

    With big brakes, you're able to modulate that power right on the edge of the tyres limits much better, braking right up to the point where you can actually hear the tyres about to let go, and holding it at that point of maximum deceleration without ever actually locking up.

    We'll go to 335 next time, simply because the 335 discs are only £5 more than the 330's, and we will go for a wider disc to increase the air gap between sides of the disc, so increasing the amount of air passing through the disc and thus the cooling capability too.

    Pad wise I'll be sticking with these RS29's for as long as possible on these discs, then have a re-think when it's new disc time.

    Power wise, we've never wanted anything more since the LCR brembos, so it's all about heat management now.

    Main reason for floating is to eliminate the risk of judder when hot, as we seem particularly susceptible to this for some unlucky reason.

    Maybe due to you physically standing on them mate!!
    Honestly your brakes dont stand a chance.
    As for oem brakes locking at 100mph. Really?
    Ive has scary moments at under 30mph! they do nothing lol. Must have cheap pads or something?
    Anyway any improvement on what you have will be unreal!

    Sometimes, when off the shelf stuff won't do, you are faced with no option but to have parts custom made to suit your requirements.

    This is where people like Bill come in, who despite being flat out busy tuning customers cars, has managed to find time to get these beauties made :)


    [​IMG]

    Custom made Badger 5 8'' PCD bells for floating discs, which allow me to float my existing discs using an AP Racing bobbin kit :)

    I've wanted some different form of pedals since I built the car, I had the TT covers originally but moved then to my other back in the day.

    Brake pedal travel is ever so slightly increased with the forge brakes due to piston sizes, and to be absolutely perfect for me I could do with having te brake pedal 10-15mm higher so its just at that sweet spot for heel n toe braking.

    I've been speaking to a good friend who races in the mx5 cup and he's shown me that getting the controls perfect is SO important, hence the gear lever re-work.
