I have recently fitted a set of yoko parada spec 2's on my indy and just noticed that the o/s/r tyre
is scrubbing on the inside edge.
It is also feathered as though the tracking is out,though there is no adjustment on the rear.
The camber seems fine on all wheels and there is no play evident in any of the bushes.
The other three tyre's are still as new.

Any ideas guys,before i have to replace a tyre that has done less than 800 miles????

Cheers,

Andy

Check the rear tracking and also the camber , even if the tracking it is not adjustable it could well be out and if it is wearing on the inner edge it would tend to indicate toe out which isn't ideal.

Ok,so if the tracking on the rear is non adjustable,how do i adjust it?

Sorry if i'm being a bit thick like

You either:

1. Don't.
2. Start shimming...
3. Start chopping.....

Worth buying a Gunson Trakrite it will tell you the toe across the axle to a high degree of accuracy, ideally you want some toe-in on the rear. Any toe-out on the rear can make the handling really nasty so if it suspect is toe-out you will need to fabricate some sort of adjuster either on the wishbone or by modified chassis brackets.

You also need to look at the camber and corner weights particularly when the car is loaded up as you would normally drive it --- ie with the weight of the driver onboard.

Thanks guy's.

Either way this is going to cost lots of money.

Andy.

Shouldn't be too expensive - Trackrite is about £40. I think you can shim the rear hubs / uprights to correct toe problems.

I checked mine [MK Iindy] recently and had 1 degree toe in on each of the rears so yours should be about the same.

why not take it to somewhere like Kwikfit and get them to measure the angles. Use that to then shim out the back upright with some washers. I set wheel alignment using nothing more than a piece of (straight) angle iron clamped to the wheel rim, you then sight along it till it lines up with the edge of the other wheel on that side. Works very well tbh.

If it's independent rear then file slots in the brackets and hold in place with a tack welded washer.

Thanks chaps,

I dont know what i would do without you all.

It might not cost that much to rectify after all.
