Adjusting rear toe

[sdio]

Hi all i noted my car has 1.1mm toe out rear left and 2.2mm toe out rear right.
Can this be adjusted and to what figure ?
The car is on watts linkage.
Thanks

You can buy rear shim kits to adjust it such as http://www.dpr-motorsport.com/accessories/caterham... . Personally I would match each side with the watts linkage length - or at least check there's not error there - and then shim for zero or a little toe in. But these setting are really up to the individual and what they want to achieve.

Thanks for your advice David i will do just that

Is it worth checking the De Dion tube is straight first?
The rear wheels on my car are parallel.

What i found wierd is there is toe out rather than in both sides so i guess must be some sort of watts adjustment

I've found that the de dion tubes are not always 100% square and the welding process can introduce some distortion. It is also possible to transfer some of the 'camber' in to 'toe' if the tube rotates due to incorrect watts linkage lengths and/or extremes of ride height. Of course bent ears and tube can cause problems too.

If it's toeing out, and there are no shims in it, something's bent.

No that i hear about the use of shims i am quite sure my car has some on the end of the dedion shaft. I will go and check.

It's worth checking the end welds on the dedion as they do fatigue and crack. Im on my third tube (race car though). Also worth checking the A frame is straight and in good order.
