    I can't really suggest anything you won't have already checked Nick, my only additional idea would be to mark the bolt heads/nuts/bush sleeves/solid mounts with something like torque seal. Just a quick line down them onto what they're bolted to. I know they're not loosening so probably aren't rotating (or at least if they are, they're rotating back), but the proper paint's thick and brittle, so it's obviously cracked if something's moved at all, even if it's just shifted fore/aft a fraction of a mm. It should show up any movement, or at least put your mind at rest about things that aren't by providing some solid proof that they really aren't.

    Do your KW's use an inverted damper with a bush in the strut body? If so, it's a lovely stiff design but does seem more prone to wearing out the bush than normal dampers. Definitely worth checking anyway, the rally car needed them doing at the start of this season.

    Also, I take it you've checked the rear beam bushes/mounts? Just in case.

    Audi/VW say so. I can;t really understand why, as its a nut and bolt. So its not stretch or anything, but its definitely what they recommend, and did make a difference for me

    £35 spent on bolts at TPS today, all new bolts for the front subframe and wishbones.

    Will throw them on on Saturday morning :) and see what happens!

    Thinking in general regarding the suspension and the clunks etc, since we have been running slicks with this setup, the g forces are considerable and what used to be, will NOT be now. Has to be more wear and tear on everything. I remember putting wider more grippy tyres on the A4. Wheel bearings did not like it. Not what it was intended for. So had to uprate. We have the choice, maybe extreme ironing, fishing, (get real) gardening, oh and crosswords. OR track cars.

    8 in total Daz. Not the cheapest!

    most of them were about £2 each, but i think the subframe ones were something silly like £4.90 each, so it bumped up the bost.

    4x subframe bolts, and 4x wishbone bolts with nuts. Will fit those and spanner check everything again. i've also softened the front ARB to soft last weekend, so looking forward to seeing how that changes things.

    Next up - a bit more remedial work to the splitter with some wood glue, then new discs and pads and more cooling :)

    Just being really aggressive on the outlap Jim. Being a sprint, you get a 30s outlap, then just 30s flyer to make it count, so on the outlap I'm as aggressive as possible on the throttle / brakes and steering to try and generate some heat in the tyre and brakess in the very short time you have.

    Aggressive turn in on power with a big lift sees the back end swinging round no trouble, even on warm tyres :)

    So, time for a slightly better write up of Curborough.

    Yesterday was the first Club GTI Curborough Sprint of the year. CGTI usually run 2 days a year, in May and September. This was my first time attending a CGTI Sprint, and my second time at Curborough.

    AndyP came with me for the day, and we left mine at 06:30. No pictures. it was early!

    There were 22 cars in attendance, from standard mk2 8v GTI's, to turbo'd mk1's, mk4 track cars, and all sorts in between. I was the only non golf on the whole day!

    We took a vote in the morning, and decided to run the new figure of 8 layout in the morning, then switch to the old traditional layout in the afternoon to get times comparable to past events.

    Sadly, it rained LOTS early on, so no pics, and I didn't remember to film any of the morning runs on the new figure of 8 layout. was too busy having fun!

    It started to dry up a bit later though:

    A little pic of Gurds amazing mk1 - ABF turbo with a GT28RS. Such an awesome car!

    There was lots of queing in the pitlane, and moving forward one car at a time. It got a bit tiring jumping in and starting it each time, so we found ourselves a Sam Gunn :laugh:

    [​IMG]

    The day went really well, and I even managed to come home with something for the mantle piece :)

    obviously I wasn't there, did softening the front ARB make much difference on slower turn in's

    Hard to say BBD, as it was all pretty slow. Car was certainly handling well though :)

    Noise is still there, but I'm not too worried. A bunch of had a good look over it, and checked vital parts whilst it was knocking by walking along side the car with hands on components.

    I'll strip off the splitter at some point and check everything that's hidden under it.

    There is very little body roll on the sharp left hander you liked, especially considering you have softened the front up.

    Thanks Bill. I used the hard compound Dunlop Direzzas that we use for road miles. The CGTI day requires road legal E-marked tyres, so no slicks or wets tried at all as it's not in the 'spirit' of the day :)

    Was a really good fun day though, I was pleasantly surprised by how the heavyweight A3 performed compared to the featherweight mk1's!

    I think a crash course in weight loss is certainly in the pipe line over winter. It'll improve it in every way I think.

    What exactly are you going to remove though?
    Have you lost all excess wire?
    How about cut out all excess metal from inside the car?
    How much more weight do you think you can lose?

    All of the above :racer:

    There is loads of excess metal inside still, double skinned areas etc etc, the radio and CD changer are still in at the moment, all the original wiring. I think it should be fairly easy to strip more out, but only once the car lives tucked away in a nice garage away from the elements

    SMALL??? 6 m full height inspection pit, (the end of which is for storing tyres) overhead storage in roof space, electric hoist (two way) for engine removal, toilet and shower, 65" plasma television with surround sound, and wifi . Can't think of anything else at the moment but will work on it. I'm full of ideas.

    Congratulations Prawny, wish I could have popped down for the day to see you on your own personal time attack lap, but work stopped play for me. :(

    You still running a similar set-up to when we met down at JKM?

    Cheers John! Good to see you on here too :)

    Same setup as at JKM pretty much yea, aside from an added inline fuel pump that we found to be the cause of the issues I had at JKM :)

    Will you be at the September Curby event?

    Also interested to know if you sorted this?? Had a look over mine and found a bolt missing from the dogbone mount and excessive movement in the front drivers side coilover where the shaft goes into the shock :(. Time to look into the kw rebuild service or maybe new coilovers. Im sure youve checked this though so probably not related to your issue at all

    So, a good day today. I had LOADS of random jobs to do, and seemed to get a fair few done. feeling happy :)

    We started the day like this:

    [​IMG]

    Up on stands 5 minutes later, and splitter off. My captive mounts were doing their job. Considerable wear on the bar here, but easily removed still :)

    [​IMG]

    The splitter has taken a real beating over winter, and has delaminated a little. I decided to get busy with the wood glue today, and I've also sanded it down ready for a fresh coat of paint all over to try and get it looking fresh again:

    [​IMG]

    the threads on my gearbox looked a little worse for wear, so I decided whilst it was all apart to helicoil both of them.

    The holes were drilled out, and tapped:

    [​IMG]

    And the inserts wound in:

    [​IMG]

    To create a nice new stainless steel thread:

    [​IMG]

    Also, as part of my clunk hunting, I replaced the front wishbone bolts.

    Now, I know I said I replaced these last week, but if I'm honest, I actually only replaced the rears, as SURELY the fronts couldn't be causing an issue.....

    .....could they?

    Old vs new:

    [​IMG]

    I'm told that shoulder is a feature, not wear, but whatever it is, changing them has cured the knock! SO amazingly happy that the knock has gone!!!!!!!! :laugh:

    Quite a fiddly one to do the 90 degrees for the stretch when at ground level. So I torqued them up to VAG spec, and marked them with a vertical line, then tightened them until the lines were horizontal :)

    [​IMG]

    Going well so far......

    On to brakes.

    It was time to retire the old second hand AP 330mm drilled rotors:

    [​IMG]

    The replacements: a set of Compbrake Powervane 335mm rotors:

    [​IMG]

    To be combined with some Mintex F4R pads. Steve at Questmead has been trying to sell me a set of these for 3 years, so I finally gave in. Time will tell how good they are :)
