I calculate it to be about .25 degree, but I was never much good at all at maths.
Perhaps Mr T can input ......... he knows about such things, including on Clubsports ..... and somewhere I vaguely recollect that the OM camber / toe figures likely related to Avon crossplies rather than the radials that most roundy roundy people use nowadays? - as they 'move round/sidewall flex on the rim way more than crossplies, the radials need much more neg camber than the crossplies ........ no idea what this means in terms of the toe but I suspect it's dramatically increase the camber for radials then reset the toe to match the original crossply settings?

While I think of it ........... as 'toe' is the front or rear pair of wheels 'pointing/splaying in towards one another' or 'pointing/splaying out away from one another' relative to the forward direction (not meaning going backwards at a forward rate of knots through Coram etc! ), if 'toe in' presumably we're talking rears, because as noted above, fronts are inevitably 'toe out' - not that the OMs always make that clear, although the latest RS one does ......... unless of course, a Clubbie does things completely differently
The OM does say 1/32/wheel toe in, but do I take it that this should be toe out? Or that those who know what they are doing run with toe out?
Is the triangle formed from the centr of the wheel to the leading edge of the rim?
My car came with radials fitted but set up for xplys, so I negative cambered as far as I could (about 3') then adjusted the toe in, but the heat pattern suggests I have too much negative and inner edge wear suggests I have too much toe in.
Thanks for all the replies

Sorry, it was me that was unclear. The OM says 1/32"/wheel toe in for both front and back.
No problem.We could do with a Clubbie Wizard and/or Official Radical stepping in here pronto!
I'd be surprised if they actually meant to say that in the OM: I don't think I've ever seen a Radical with front toe-in - pretty sure that every Radical I've ever seen has significant front toe-out (and quite a lot of negative camber) when running on radials; as I would expect, as front toe-out in a rear wheel drive car helps the transistion into turns (at the expense of straightline stability which is not so much of an issue in a race car). Compensating rear toe-in is an integral component of that smooth and ready turn in as an entity. Kind of proof of all this for me is for example our RS which is 2mm toe out each side front and 2mm toe in each side rear as the standard factory alignment settings. Your apparently excessive inner tyre wear also surprises me: if you mean the front and you're running with toe-in at the front (when I think you should have toe-out if anything) I'd expect the outer to be getting hammered by severe scrubbing through the turns. Strange.
(Sorry, there was an error in there - got one of my toes pointing the wrong way - just corrected)
