the only concern really with doing this is the change in position of steering pick up !!! a narrower track will not have the dia consequences you guys think !!! susoension geometry will be the same a shorter arm will result in slightly more camber change under cornering. i would like some advice on what affect moving the tie rob pick up at the outside will have ????
been to say my mate and im getting new lower arm made with adjustable ball joints so i can change width of track. gonna go for a neutral reduction of 20mm each side with 5mm of adjustment each way, so could -25mm or -15. driveshafts going to get made shorter and buy adjustable top mounts. this seems like a lot of grief to get the ronals on but i always wanted them so i may as well make it right !!!!
It would be easier and safer to get some Audi 80 4 x 108 hubs, and drill and tap to 4 x 114. There is enough meat in them to do so. Have the bearing diameters on the hub turned down to suit 321 498 625D wheel bearings. Have the bearing housing bored out to suit 321 498 625D wheel bearings. Fit Audi 80 outer cv joints. This is what VWMS did on the Golf rally cars.
it sounds like you are investing a lot of money and time into this. I may be coming over a bit negative, but all I'm trying to do is help you make a better car. Lots of folk on here have played with mk1 suspension and have arrived at various conclusions about what works and what doesn't. I'd have a look at what Danster has brewed up on his scirocco and cut and shut the arches until it will all work with your fancy wheels and low et. wide steel arches following mostly the original form would look great too
That is a potential solution to making the wheels fit the hubs, but will not sort the track problem caused by attempting to fit wheels with the incorrect ET. Another thing to consider is when steering lock is applied, will there be clearance for the rim and tyre against the arb, wishbone and inner wing. Never mind suspension and steering geometry, that is for gheys! You could stop the tyres hitting the wings by running 20deg neg camber too. As Prof mentions, I acknowledge what you are attempting to do too. It will be a good engineering exercise to try to make it work, but I can't help feeling there would be a better and easier option.
Danny. My solution gets rid of the 20mm thick adaptors, mentioned below. As in post #1, jonlen is looking for 20mm. Job done!
3 pages into this thread, and as VWSingh asked early on, what are the wheel sizes? Just read back through posts and all we know is they are 4 x 114. No diameter, width or ET mentioned. If they are 13 inch rims with 239 brakes, for 20vt power? Bonkers
I don't think it'd even need that, some proper steel repair arches welded on further out and blended in would be nice. Mind it'd want power steering too, so might as well chuck the whole mk2/3 subframe on and have done with it
Aahhhhh, I think they're old style ford PCD maybe - weren't they 4x4.5" PCD? 4.5x25.4 = 114.3 Sell them to someone with a Mk2 Escort, for vast cash, and buy some rims that actually fit your car
I'd agree with Singh on the jap guess, skylines are 5x114.3 i think. Why are we guessing?! a guy asks for help and doesn't give the details....something wrong here lad
Ah, but, the bearings noted are Passat! As called up by VWMS! Audi 80 bearings are much too large, and Audi do not bother with circlips! So, one can deepen the circlip groove, for the circlip supplied in the 321 498 625D kit. Or, one can machine the hub, to give an interference fit, as Audi do! And use a suitably sized assembly spacer to make sure the bearing sits in the correct place in the hub. ps. Is deepen a real word? It looks so odd! pps. I abhor circlips. I never used them in my machine designs. I always used spiral retaining rings. ppps. Saab used spiral retaining rings. Guess why I used them? http://www.smalley.com/
One for a separate thread, but fascinating. There was a lengthy debate about drilling out Mk1 hubs and having no circlip groove left. Passat bearings I would like to be educated on all of the above boss! My Gemini gearbox has two external spiral retaining rings on the end casing
