  1. Jeez, ages since ive updated this, alot has happened since.

    Another 2 rallies have been plagued by the snapping CV joint issue, on the last stage of L'etacq attack throwing away 1st in class, and on the first stage of a dirt rally while the misses was driving. 

    Mk2 golfs seem to have a similar issue, especially those in America who rally them. The 'cheapest' solution seems to be use Audi 80 cv joints (which fit on the stock shafts), then get the hub machined for a larger bearing and modifying some output flanges to suit. I have had this done now and so far has held up with no issues. one issue we did have was the gearbox.

    At a hillclimb the gearbox gave up on me shearing 2 teeth off the pinion gear which ejected out of the side of the box.

    An upgrade was in order and i bit the bullet and went for a dog box from SQS, along with their sequential shifter. Assembly wasnt the most straight forward however its in and the shifts are mega!

Car was faultless

    Over winter the car will get a good once over before next season but am toying with the idea of moving onto another platform/car.

  2. Its about time i posted an update on this. Since the last post the following has happened:

    The old CV have been replaced with new SKF items, the quality seems pretty decent so hopefully will last a year or two between getting replace.

    I have had some plates made up to strengthen some Febi lower arms, whilst seam welding and strengthening as per the lupo cup cars, hopefully this will stop this type of failure in the future.

    I have also fitted a front anti roll bar from a stock lupo, 18mm i think, the 22mm bar from the gti felt too stiff and was quite understeery, i liked the feeling of no from arb but after seeing this picture realise i needed to sort out the roll.

    Some new wilwoods were fitted, this option let me change some spacers if i want to run 14's for dirt rallys, not convinced on the pedal feel yet but we shall see.

    I 3D printed some brake ducts aswell and painted these to try and keep brake temps down, a lick of paint and i think they look acceptable.

    I have done a sprint, autotest, a hill climb and a dirt rally since and the car has been brilliant and very competitive, i even managed to get a fastest stage time at the dirt rally against some faster cars.

    Hmm yes, so why do you want heat not to transfer out of your pads faster using a better thermal conductor than Titanium? There’s a reason, as these teams won’t be doing it otherwise as you say but the lack of science over it makes me think it’s a bit… pointless 🤣

    they way i understand it, you dont want the head going from the pads, into the pistons and seals, thats the purpose of it to stop the heat transfer

    I told my gearbox man about 6th gear and he said it's possible to remove without hacking the synchro - just have to know what to do apparently!  When he next calls I'll have to ask what parts can be upgraded on the original box.  I don't intend to get this serviced (other than oil changes) for the next 10 years!

    I thought the same until it came to doing it, hopefully I’m wrong let us know how you get on, upgraded parts would also be nice to know

    Thanks for the tip mk2.  You say stay clear of the cover - as in, don't even take it apart?  Wouldn't the bearing in the cover not be a viable thing to renew if it's placed under a lot of lateral load?  Would you know anything about upgrade parts to renew?

    from my experience replacing these bearings is a piece of cake with the right tools, mk2 is correct regarding the alignment of the bearings but a gearbox man should know what hes doing, removing the 6th gear is not possible without damaging a syncro in the process, this increases built costs £50 ish, FYI

  6. I’ve had the exact same thing happen today, but caught it before they sent the wrong ones, they always do this with stuff

    one person said they were out of stock, the next said they would send the right ones

    can be a pain but often cheapest place for car parts

    Morning Andrew - hope you're good too.  I think you're right - I've tried following up a few on eBay after searches, but there doesn't seem to be any actually available.  I'm just trying to get ahead of possible future MOT failure;  the things are a bloody nuisance, as is the spoiler - one of the most irritating aspects of Lupo Gti ownership - though most other things continue to make having one a real delight, especially as cars generally continue to get ever bigger and heavier. Regards. D

    id be tempted to get it smoothed over and repainted, i presume they wont fail you if there isnt a 3rd brake light there?

    Hi again all. Thought I'd return for a bit of a discussion.

    It's becoming more apparent that VW are dropping items from production / stock, and as such some parts are harder to come by. I thought it would be interesting to try and compile a somewhat list of those "Rare" parts, whether they simply be OEM replacement parts, or even aftermarket ones. 

    So if I kick it off:

    • Lupo GTI Ball Joints
    • ABT Grilles
    • Lupo GTI Headlight Washer Jets & Covers

     

    You can get aftermarket GTI ball joints pretty inexpensively 

  9. St suspension are a decent option, made by KW but less expensive and have lasted me a while, had them 2 years as a road car, then another 2/3 as a rally car and cant complain.

    i think the gti ones 'may' fit, but if your buying new i cant see any benefit from buying them.

    Yes they will need the 'ears' that bolt to the hub

    What RPMs did you tune your trumpets to work at? They're pretty short, so around 6k? Are you allowed variable trumpets in your class? You could go all Porsche on them... :)

    I imagine that CV stub went with a bang. Much damage made while flailing about? Nightmare! Could've been nothing more than overtigtened bearing nut?

    ill be honest there wasnt much 'tuning' involved with the trumpets, there isnt much room under the bonnet and airfilter for them so just made them long enough to fill the filter whilst leaving some space. the outer 2 are a tad shorter becasuse of the curve of the filter.

    luckily it didnt take too much out, had just gone round a tight bend when it went, it bogged down so gave it a clutch kick (which obviously isnt the nicest thing to do) and bang it went. could have been an overtightened nut. They do get tightened pretty tight. The weekend was very dry and hot so pretty tough on drive train to everyone, a mate of mine snapped one on his bmw on the first stage.
