Hmmm - confused. biggrin..Fitting narrower front tyres to an Ultima seems quite bizarre. As we have all discovered the turn-in on these cars is limited by front grip which causes understeer. Reducing the front contact patch will increase the understeer - not nice - OK for gaying down to the pub but useless if you want to do any serious driving.

I put 255/35 on X8 GTR and aside from grinding the front return lip off, there was no issues. Perhaps all bodies are not equal.. For track use I definitely could have done with more front end grip and was going to fit the 285/30 fronts with some aero but didn't get around to it. I reckon if road legality is not an issue the V70A is more grippy. For track use slicks are the answer.

An easy solution to your clearance issue would be to get the nice man from Image to wizz you up a different front rim to set the tyre a tad more towards the inside of the car. I believe he is the only bloke in the UK to still be spinning his own rims. Not expensive.

Hi Dom,

I couldn't detect any diffence with 2 dive planes on a standard car. Didn't expect much at Brands but had hoped for something through Fordwater at Goodwood. I reckon that without a big splitter, flat floor etc. probably not much use. However, 4 dive planes, big splitter, flat floor, 285 fronts etc is good.cool

The 255's can do with another 1/2" in rim width and together with spacing the wheel towards the centre of the car can only be a good thing as it has the obvious advantage of setting the brakes deeper in the wheel. http://www.toyo.co.uk/productdetail.php?identity=p...

If you are near Image perhaps it would be worth popping in and having a chat. I think it was about £200 a corner.
