I was asked to post a pic of my tasty new top wishbones, sorry about the pic quality the garage is not a good place to take them.
I have taken it to show increased castor.

Whats the turn around time for the wishbones.
I'm tempted once I sort out the exhaust volume.

Considering the cost of a re-test its about the same price for a set of wishbones once I've added petrol to get to the IVA centre.

Thankyou for the photo it was me that asked
They look the dog's bo---k
can i ask what they cost please
Graham

They are £145 including all the rose joints alloy adjuster tube and spacers and washers and powder coat and postage. Turn round is approx 2 weeks.

Have you driven it yet?

Stu

Not yet, i am expecting the same improvements others have had. I will try and get out over the weekend. I will post my findings then. Steve

the other great advantage is that you now have full control over camber adjustment as opposed to the oh well it's within one turn,
you will be impressed at the difference.

Comparing that pic to my standard Indy bones it doesn't look like it has any more castor. Hard to tell just by looking though.

Cheers for that stevec, I'm now £130 lighter of pocket

The standard Indy wishbones do have 25mm of castor built in. I'd advise people to actually check their castor before splashing out on a pair of adjustable ones because they may not actually be needed.

It's relatively easy to measure castor. Once your chassis is level, remove the whole front wheel assembly so you just have your upper and lower wishbones in place.

Mark the centre of the bottom ball-joint hole on the lower wishbone and then drop a plumb-bob through the centre of the hole on your upper wishbone till it meets your lower wishbone and simply measure the offset.

25 mm equates to 5 degrees.

My Indy is a standard set of wishbones currently (from 2007 Approx).

Lovely return to center on steering, but only in reverse. Absolutly nothing when being pushed forwards direction.

Yes they don't look too different from my MK ones either, but its hard to tell from a photo.

Ive spent the last 25 years building and setting-up cars for both track and road use and would like to think I have a fairly good idea on how to get a car to handle.So when I was approached by a customer(forum member) to make a set of Wishbones to overcome a problem he and others had I took the time to take geometry data from 6 different cars useing
professional equipment not a piece of string.
Of the 6 cars only 2 achieved Castor settings of 3 1/2 degrees and only 3 had the same settings on both sides of the chassis.On investigation the problem was found to be not just the wishbones but the positioning of the mounting brackets on the chassis.
As with many things in life a compromise was found in the form of an ADJUSTABLE top Wishbone(unless you want to attack the chassis with an angle grinder and welder) allowing both Castor and Camber to be set.
As for "splashing out" on a set I will let the positive customer feedback answer that one.
Many thanks Warren

Hi

I will add a bit of weight to the above comments. I have setup and measured many many MK Indy's. And have also never found one with more than 4 degrees of Castor. And that one only had it on one side.
To gain the correct Castor and to equal it up on both sides you will need to change from the standard MK wishbones to be able to adjust out the high inaccuracies that are in the chassis.

Cheers Matt

As Wozshers comments seem directed at me, let me explain further.

I am not suggesting that the Indy chassis doesn't have inaccuracies and I also think that the wishbones he offers look quite good and certainly most people who have bought them seem to be happy with their purchase and the transformation in handling they give.

What I am suggesting, is that rather than assume that the castor on the MK is wrong from the outset, for people to actually check it before deciding to spend £100+ on a pair of wishbones to correct a problem that may not exist!

Unfortunately, many people don't have access to specialist digital measuring equipment so I would suggest checking the castor with string. Unlike digital equipment, string doesn't cost a lot, doesn't need calibrating, doesn't usually go wrong, doesn't need power and nine times out of ten will give a true vertical line if a weight is attached to the bottom

If that ultimately leads to only one person out of a hundred who doesn't actually need new wishbones, then so be it. At least they'll have saved some cash.

In addition to Warren's wishbones [which look top quality] I guess I'd need to factor in the cost of getting the geometry properly set up as well, which I imagine would add as much again to the overall bill, and is probably a pain to find some competent to do it locally.

Obviously this is also applicable to the standard wishbones as well [except for the adjustable castor- all the settings on mine are home measured at present].

wozsher,

Could you please contact me re. quote for a polybushed version please?

Thanks,
Sebastiaan

Morning All
Just my 2p's worth, It all started months ago when I saw Hellfires front wishbones and I decided this would cure my problem, tried numerous times to contact Mr MK (martin) but no joy, so contacted some of the chassis and parts manufacturers on here again no joy, then I saw an advert of some adjustable wishbones for the haynes roadster by a guy called wozsher, so I sent him a U2U asking him if he could make a set for my MK, within 48hrs he had made a set after locating a local Indy to take measurements off, so that's the story of how it all came about.
I agree totaly with warren about the brackets not being lined up properly on mine I have 4 washers at the front of the wishbones on one side and 3 on the other, from memory I think the top joint as set back 15mm more than the std indy wishbones.
sebastian don't bother with polybushes go for rose joints.
Next project I want him to work on when finances allow is a full set of rose jointed (fully adjustable) rear wishbones for toe in as again I appear to have toe out on one side of my chassis.
Just like to add I have no connection with warren other than the fact that when I needed someone to do the job he stepped up to the plate.

tony

Unfortunately there isnt an easy instant fix for this problem.But considering the amounts of money some people are spending on their cars then the cost of having the car set-up correctly is relatively small.I can only suggest that getting the basics right is the way forward.
Many thanks Warren

I've fitted my new wishbones tonight.
Using a single washer + the rose joint spacer on the rear side of each joint.
Gives a really decent offset which looks a lot more sensible.
Certainly also a lot quicker than fitting the MK ones which took sodding ages originally and as I can see from the brackets, splayed them out slightly during fitment (as they didn't alight with the wishbones properly).

I think I'll be after a set of rears too as I can see the toe out on the right hand side.

He did mention that its possible to modify existing rears for a bit less than making up a new set. It'd be interesting how much this costs cos' I'm very interested in having it done.
