LR5V Posted November 17, 2019 Report Share Posted November 17, 2019 I believe there is only one post on here with someone who got the correct sized aftermarket ball joint, the brand they got was not mainstream, unfortunately the PN they shared didn't work. Lots of comparison pictures in posts, Gti ones have a longer tab that fits into the control arm. When you search online they just lump the Gti in with standard Lupo ball joints. some people have had the short ones fitted by garages who didn't check size and had problems with drive train.

axe Posted November 19, 2019 Report Share Posted November 19, 2019 (edited) yeah I found that post the other day, was the RTS Spanish Ball joint. 93-90973-156 for right and last 3 digit 256 for left.

imaparana Posted February 13, 2020 Author Report Share Posted February 13, 2020 Not much up an update as i keep forgetting to take photos, but.

I looked into it and I Can get genuine here in Japan but they're well over 100 GBP a side! Got the aftermarket ball joists all fitted and seem like the right fit! ive made up a fibreglass bootlid with integrated boot hinge mounts which needs a lick of paint and will be able to be thrown on the car. I managed to get a Dbilas Dynamic intake manifold, which ive gold tape wrapped and fitted with a thermo spacer intake gasket to try and keep the intake temperatures down (the exhaust up to the 2nd cat has also had exhaust wrap on it). Ive had to re-route my induction kit also. The project silver top mounts id fitted developed a knock after the crash so i have reverted to standard for now. Polycarb windows are in also to replace the smashed ones. The tailgate window and right rear quarter window will need to be done after the next rally. Both seat mounts have had to be replaced as these got pretty bent up in the crash also. Next event is the Bovington stages at the end of the month so will update again after that. 2 Quote Link to comment Share on other sites More sharing options...
imaparana Posted February 13, 2020 Author Report Share Posted February 13, 2020 (edited) These are the ball joints: 93-90973-156 & 93-90973-256, I ordered through autodoc. Edited February 13, 2020 by imaparana 1 1 Quote Link to comment Share on other sites More sharing options...
LR5V Posted February 13, 2020 Report Share Posted February 13, 2020 Top mount bearings should be replaceable -I looked at mine, seems to be a top hat insert needs pushing out to reveal a cir-clip. usually they use standard sized bearings -try Merlin Motorsport for NMB or Aurora ones.

imaparana Posted August 8, 2020 Author Report Share Posted August 8, 2020 (edited) Sorry about the lack of update, so heres a brief one! Back before corona times we took the trip to the UK and did the bovington stages, car ran fine (apart from boiling brake fluid) and ended up 18th out of 47 entries. Was a cracking fast event. I have done a few updates during the covid-19 lockdown, including stiffening up the engine mounts with polyuerethene rubber, and triangulation and polybushes to the rear beam. Today we did the first (and maybe only) rally of the year over here, was a small entry of only 8 due to local restrictions, me and the mrs did a joint entry (2 navigators required) down at the local quarry, was up to 3rd out of 8 beating some fast cars and doing well, until on a change over there was an increase of vibrations, due to the fast change over times there was no time to investigate, launched it off the start line and broke a shaft (stage max for us 1:30 off our times), upon replacing the shaft we realise there was a broken top engine mount spares all fitted in time so the misses didnt incur a penalty! got her all up and running for the rest of the event, ended up with a 4th and 5th overall. The lupo was a proper force to be reckoned with on this type of event and cant wait for the next one. watch this space for more juicy updates soon Edited August 9, 2020 by imaparana 1 Quote Link to comment Share on other sites More sharing options...

Thanks, it was ATE typ200, ive splashed out on some castrol react so fingers crossed that solves it. if not i need to man up and use less brakes Yes thats what ive done, it was done in the lupo cup and aslong on mk1 golfs Quote Link to comment Share on other sites More sharing options...

mk2 Posted August 11, 2020 Report Share Posted August 11, 2020 I dunno if i like the idea of putting rose joints on the rear beam like that. Bigger anti roll bar, yes, but you want the ends to move a bit? lamborghini (and maserati) had loads of trouble using rose joints on the front of their countach. They're great in aircraft and boats, but i was always taught that you need the flexing, or you get cracks. Namrick dot 5 fluid used to be good. Not used it for a while. But i found that the piston seals give up sooner when you run hot. Rubber doesn't like being cooked. I wonder if you can get EDPM that works at high temps? Not my area of knowledge. @Skezza is our forum's chemist.... Those are some great pics! That quarry shot?! Cool. I love the custom brake system that I guess runs the rears?

I’ve also fitted some rs3 ducts that fit on the lower arm to help duct the air (forgotten how much I’ve done over lockdown) there is a lupo cup car brochure floating around, if you want it pop me a pm Quote Link to comment Share on other sites More sharing options...

The bars aren’t to stiffen the roll of the rear beam, but more to stop it bending inwards or outwards during cornering, was more of a while I had the beam out mod, not really sure it’s made much difference tbh but more of a belt and braces approach. ill see how the Castrol stuff holds out on the next tarmac event long enough to give me problems. yes it’s a hydraulic handbrake plumbed into the rear system Quote Link to comment Share on other sites More sharing options...
Skezza Posted August 14, 2020 Report Share Posted August 14, 2020 Curious about this boiling brake fluid. How do you know it was boiling fluid? When was the last time you changed it? How often do you do it? What method do you use? Quote Link to comment Share on other sites More sharing options...

The reason for the thought of fluid boiling is the pads I’ve got are very high temp pads, the fluid wasn’t the highest temp stuff available, it’s been bled very regularly Quote Link to comment Share on other sites More sharing options...

mk2 Posted August 16, 2020 Report Share Posted August 16, 2020 I was thinking that somewhere air is getting sucked in. You know, that seal on the shaft or plunger that pushes the piston on the master cylinder. Even if it boils, then cools down, you shouldn't get any air (or gases) produced. How have you plumbed in the rear circuit? You still running diagonal split or just fronts? Quote Link to comment Share on other sites More sharing options...
Skezza Posted August 17, 2020 Report Share Posted August 17, 2020 Have you seen bubbles since? Could it be moisture? Quote Link to comment Share on other sites More sharing options...
