OK getting their!
Need someone to do me a favour now, im here at work (Qatar) and cannot get to my car which is in Spain and i need a dimension.
I need to know the dimension from the hub face to the inner wheel arch, i need this to make sure that when fitted with tyres the wheels i order dont catch the inside wheel arch face.
So negative offset puts the wheel outover and should end up giving what looks like a dished wheel? is that correct?
Regards
Steve
yeah negative = more dish (looks good also
)
Assuming your inner guards are the same as a regular 131R (I don't see why they wouldn't)
Tts hard to get an accurate measurement, and my car has a 132 rear axle so the track may be a little different - but after playing with a tape measure and feeling how much space there is behind my rims (14x8 with around 0 offset) i get the feeling much more than about 100mm, maybe 125mm and you would be very close to rubbing on bump unless you have very stiff springs.
Also at the moment I have quite small tyres with some stretch on the wheels as well 195/45/15 - this means the sidewalls dont buldge out at all - 285/295 will be buldging out unless you have an 11" or 12" wide rim.
I dont know how easy it is to get tyres that wide in a low enough profile to keep them away from the wheelarch as well, since I would say you probably want to keep under about 600mm overall diameter. (taller tyres raise the car too).
Anyone know what the original tyre size was on a gp4 131 abarth?
