It's what one is accustomed to largely, and of preference.

Your rear is solid all the time? I shall avoid the tempation to suggest that you increase your vegetable intake, or not! For my tastes, it suggests your car may be a bit over-rubbered if it will not oversteer.

That doesn't make it wrong, it's just as Brian said, a matter of driving style/preference.

For me, I have become acclimatised to very little front tyre sideslip, and the rear steering adjustability. It's what makes it so entertaining to drive.

Mine goes in tomrrow to have it put back to 01 settings! I just don't get on with the O settings.

I can concur with the opinions suggested - mine has good feel (fat too much NSF castor >7deg46!) but the steering feels rubbery and understeery from anywhere off straight ahead. This tends to lead me to overapply the power to cancel it.

Also, I notice that the RWS effect had been dialled out. I have to make minor corrections with the steering, whereas I'd use the throttle to adjust the line normally.

The front toe is -0deg02', the rear 0Deg54'.

Last time it was -0.6mm and 2.4mm respectively. How irritating that different measuring methods were employed!
Nick, don't diss the 'O' settings when your last alignment wasn't anywhere near. Almost 50% too much rear toe - hence the lack of response to throttle changes. Also with that bit of toe in on the front, it'd naturally make the car a bit more eager to turn in. It'd be interesting to see what your car gets set to this time, and how it drives afterwards.

My veggie and fibre intake is fine thanks! Solid enough in both departments

I like sticky rubber! (cue innuendos)

Oversteer is fine, drifting and rear steering is fine - for me anyway. It just takes a bit more effort

Occassionally it does scare me how solid it is round bends!
But exploring is half the fun

Brian - I owe you a beer!

I'd been mulling all afternoon that it would could be the increased rear toe in that could be producing the effect, as the camber settings seem about right.

I'd not noticed the error, because of the differing measures quoted - thanks for that.

Do you think I may benefit from a tad more rear camber? I had more before, the tyres wore evenly as I tend to power out of corners pretty hard. Or is that a bit irrelevant on the public highway? (They're -1Deg34' ish, last time they were set at -1Deg45')

I had my car aligned too with an extra -1.2deg camber at the front. The Understeer is horrible and will change it back to the original Japan settings when i have the time.
On a side note, The alignment wasn't done fully to specs.

I wish I could find the specs!

I looked under FAQs and the Faq-ing JPG was too small and blurred!

AH Now found them in a paper file!

Fc uk me! I've got the Workshop camber and the UK toe in plus a bit more!

Ah, the HUK camber is a bit more "slammed" at both ends.

The rear toe has more effect on how the tyres wear on the road. I'd aim for close to 1 degree more negative camber on the rear, certainly not less than 0'45 for road use. So take a stab at which previous front camber setting you felt worked best for you, and stagger the back from that. With the S02's at least, the outright camber settings aren't critical - they're more important with other tyres (A032R's for sure, but it's possible). By other tyres I'd include aftermarket wheels with lower profile tyres - they're likely to be more critical. (When you use larger wheels, they have to be a bit wider too. While careful choice of tyre size minimizes the change in rolling radius, the actual behaviour of the contact patch can change quite a lot. Could be better or worse - but something to bear in mind with these bigger wheels. A little work finding a better setup could really save i the longer run as you'd be likely to be able to get better handling and less tyre wear. Given the generally higher cost of lower profile tyres, a saving perhaps.).
