Who would be interested in a fully adjustable indy top wishbone

just trying to see how much interest there is out there for a fully adjustable top wishbone for the MK Indy, to see if it's worth while wozsher making some.
hopefully similar to the hellfire one below

You mean with rose joints instead of poly bushes?

Me too, depending on cost.

I should think the main point of the rose joints would be so that the lengths of the wishbone could be altered, maybe make the back shorter and the front longer, so same overall length measured at the balljoint, but more castor.

Or maybe castor is altered by adjusting spacers on inboard mount?

interested too (if they will also fit the Spec R) though I do ask if these would be needed on the Spec R as it is a CAD designed chassis...? anyone know the answer?

I think the idea of using rose joints is not so much for adjustment that would be done with the outer adjuster ( without removing the ball joint ) but more of the fact they are narrow and therefore with the use of spacers can be moved backwards to help the self centering issue with the indy (lack of caster)

As long as there was enough space to achieve the desired castor within the existing bracket that would be fine.

Not really following what you said about the moving the outer adjuster. That would affect the camber, but not the castor

misunderstanding thought you meant using rose-joints to adjust camber

does anyone know roughly how far back the top wishbone needs to go

Hi

The problem you have with that question is that no two have the same. In fact the cars have different amounts on either side by quite some margin. But the overall picture is that the lowest i have measured is 1Deg and the highest i have measured is 4.3 Deg if that is off any help. But it also needs to be remembered that there is a large amount of the overall problem based in the lower wishbones and there poor jigging.
Ideally you should be getting the lower wishbones all squared up on the overall setup and then looking at making the top arms to suit. Although this whole process really needs all the brackets taking of and starting a fresh to get it to be right.

Cheers Matt

Is the problem with the chassis or wishbones jigging or both?

Hi

A lot of the problem is in the jigging of the brackets. But also in the chassis as an overall IE Thrust line problems of up to 20" have been measured. It really is a suck it and see as there is no two the same which means it's not a common jig problem just pure inconsistency when using the jigs. The exact same problems can be found on the Mac#1. I assume that if any wishbones are made for the Indy they would also fit the Mac#1 and help with the problems found there also.

Cheers Matt

OK, I'll comment. I've never known Matt to miss an opportunity to slag off the MK Indy.

It may not be perfect, but the truth is that it is a damn good car, especially when the cost is taken into consideration (which it usually is).

I have no idea how many have been made so far, but I am sure that it is a lot, and there are many hundreds (maybe thousands?) of happy Indy owners enjoying their cars.

It's true that there is something of an issue regfarding self centring, and if you were to make some wishbones that would cure this then I expect there would be many hapy customers, especially if you could keep the price within the very reasonable MK context.
