Ok - can't remember where I left off.... this will be the last for a while - got a lot of new chores to do now that he weather is picking up.....
We have addressed the issues with clearance trouble at the rear of the car...
I want to throw some light on what is going on at the front......
As mentioned, the "new" style classic 5 spoke have an offset which is 5/8" further "inboard" of the vehicle....... great for the back where there isn't an issue until you go out to a 10" wide wheel - the handbrake cable eventually will foul the tyre..... but up front, we now get a bit tangled up with suspension.......
I chose to go with 7" wide rims to "draw" the tyre across from the outer edge - and reduce the "bulge" requiring more "lipping' and guard rolling....... it seemed logical to go this way - 205's were my original intention to fit and I wanted to keep all wheels the same size - including a spare......
You may remember, I was afforded the opportunity to borrow a 14 x 6 "new" style wheel for testing and it was at that time my measurements showed that a 7" "new" style would fit very tightly on the front.......
I came to the conclusion that there would "just" be enough clearance and the likely problems were the tie-rod end and the upper ball joint casing...
you must remember - this is a 14" rim not a 13"........
The "new" style is 5/8" further inboard - this also means that these tolerances are reduced by that amount from the "revised" or "original" styles - which most people have.........
When I got the wheels home - I put that much effort into marking up and measuring the rear wheel problem I'd almost forgotten the front.......
Both Ray Dunn (Dragway) and myself drew the conclusion from my measurements that they would fit the front - but just - 8's out of the question - 13 x 7's also a non event....... - I didn't want to go up to 15's - to me, 14's just seem to keep a normal profile..... but this is me - each to his own......
I tossed and turned on it for a few nervous nights and finally came to the conclusion I'd be forced to roll the rear guards and push out the inners....... still in deliberation on that....
I fitted up a wheel to the front and nearly fell off my perch...... at full extension of the suspension (wheel in lower most position) it just cleared the upper ball joint casing - at full lock, both left and right hands..... the edge of the rim scraped along the casing......... 8's are definitely out - and I'm almost 100% sure a 13 x 7 won't come within a bull's roar of fitting a HR disc front end..........
pix.... (to save you another 1K words)
Pic 1
This is the 14 x 7 rim with the suspension almost mid - and wheels straight ahead......
Pic 2
The same rim - suspension fully lowered .......
Pic 3
The same rim - from above - reveals how much of the "casing" has to be ground away to ensure the rim won't touch in use......... it's not much - but I feel has to be done...... fortunately, it's not the "meat" of the ball joint - just he outer casing and only needs approx. 3 ~ 4 mm removed - bearing in mind, it is only at full extension that this will happen and only on full r/h or l/h lock......
It's not a good pic, but if you scour it very carefully - you can see where I have scribed three lines into the casing of the ball joint - both in straight ahead, and each of the locks - it's along these "scribed" lines that my angle grinder will create some "tolerance"....... and of course - get a coating of POR 15 to seal the deal.........
I do possess a full set of original X-U1 wheel spacers (with factory numbers marked) but I feel the removal of a bit of "fat" is probably a better proposition....... at least this is where my systems engineer is in agreement at this point in time........
What I did not realise about wishbones - is that by their geometry (as I understand it) the upper wishbone is shorter than the lower - therefore the "arc" of both is different - the lower arc being greater than the upper one - I believe this is why the upper ball joint "draws" away from the rim as the suspension rises (wheel moves upwards).... unless someone can convince me otherwise.......?
That's about it for me for a while...... I have an arsenal of pix and measurements if anyone needs them - I knew almost nothing of wheels prior to this project....... not that I know much more now - but have been forced to evolve through the transition......
