I almost don't want to ask this as I'm sure its going to turn out bad. I was under the car the other day and for some reason decided to measure the front track width roughly and I noticed that there seems to be a difference of 5mm from the centre line to a point on one wishbone compared to the other. I'm really peed off with this, it must have happened when I had to redo the mounts after I bought Locost bones instead of the Sierra ones. Is this going to be a major problem and am I best to saw them off and redo them
For a road car I wouldn't bother if you're much further down the line. If it's a fairly simple matter to fix, then I might think about it.
Just pretend you didn't measure it - it'll be fine
Do you really think it'll be fine, its just for road use. Its really bothering me to carry on any further thinking that it'll be pulled at SVA for some reason. I've basically got to start with the wiring and put a few panels on which I haven't got yet then that should be the car all done. To alter it means to chop off and grind the offending mounts hoping not to damage the chassis below then reweld.
Are you sure your centre line is accurate?
^ That's summat that has occurred to me which is why I roughly measured it. I'm to scared to go back and do it properly
I'd make sure you go back and delete this old thread if you ever decide to sell your car on here!
i cant imagine it would make a difference. It would be intersting to know what the tolerance is for the same measurement on a std production car. I
bet they are not exactly spot on.
Better way to measure is to start with the track width. Half it. Chalk the line on chassis point and measure each side from there. Might not be much
of a diffreence then
only 5mm out - you're trying too hard.
no wonder you've not finished yet........

That's not too bad. I read something recently in Practical Classics (? or Classics monthly) about someone who found a similar thing on his
"classic". Got really worried until he measured a few others of the same type and found they were all the same.
I'd say ignorance is bliss
As a rough estimate the track width of our cars is about 1500mm or 1.5M.
Then 5mm = (5/1500) x 100 = 0.33%
I really don't think that much will make ANY difference and I would bet most cars are the same or worse, whether they're road or race cars
And don't worry about SVA picking up on it. They won't be measuring it and provided the car is structurally sound then it's not an
issue.
Modern production car tolerances are pretty small these days, but that's after millions of £££££££s of R&D, tooling, manufacturing plant,
testing, measuring etc isn't IMHO a fair comparison.
IIRC the Austin Princess was 1" longer down one side than the other.
HTH,

I was laughing after I read this, my old Mini had one front wheel 3/4" further back than the other when I measured it and it drove perfectly.
There's more than 5mm 'compliance' in your tyres....and the assorted bushes etc.

If you re-measure the track, divide by two and mark a new centre line all should be well!

mistergrumpy, panic not dear friend i have a ditch loving indy and as of yet the rear end hasnt given me any probs so i wouldnt worry amout your 5mm.
Well, I've just sorted it. It really was playing on my mind having visions of the steering trying to do wierd things and favouring a clowns car. I already had the front in bits after trying to sort my side panels so I've just gone and sawed off the bracket and remeasured (4 times!) then rewelded. All in it wasn't really too bad of a job. I had visions of summat going badly wrong and having to replace the whole chassis section or summat. I do get worried when summat goes so straight forwardly though, only one grazed knuckle!Thats good going I reckon. I'll sleep better tonight now I think.

After serving in the forces I'm aware of land rover tolerances too well and the 'monkey metal' they're made of Hmm. Makes my 5mm seem tiny

You're having a laugh aren't you?.......... Surely that can't be right.........
