Anyone with a tape measure and 5mins spare?

[Chassis 33]

Could some kind soul do me a favour. I need to know the distance from the outside face of the rim, preferably the 15" Imola (at the top) to the outer edge of the front wing. Hopefully this picture explains it better


I'm guessing it would be about 3/4"-ish depending on what geometry your running.
ETA Could you also do the same at the rear?

Hi Iain

Mine measures 22.5mm vertically above the wheel centre. I am running 1.5 degrees of camber and 15" Imolas.

Directly above the hub centre, mine's:
o/s 21mm, n/s 23mm
on 15" Imolas
rears are 24mm each side

Nowt wrong with that... seen plenty with way more difference than that (including mine). It's called 'character'

Cheers folks, just what I needed for this

The red line is the 15" Imola and a 205/55R15 tyre at 1.5deg camber, the blue is a 9x17" ally with a 235/610R17 slick at 4deg camber, the white curve at the top is a sketch of the wheel arch, and green the ground plane. The white V is an approximation to the wishbone in plan. All very simplified I know, for example camber doesn;t alter the way I've sketched it, but it gives me more confidence to go out and order 8off rims!!!

Any idea of the rears or are they about the same?

If you're planning to use this information to decide what wheels will fit a specific car, you might want to bear in mind that the bodies are usually not symmetrical from side to side and aren't always positioned on the chassis consistently either. If you need to know what the measurement is on your car, you'd better measure it on your car.

Yep and they varied from car to car depending on which mould was used. Measure on your car and go with that.

Yes yes yes, thanks Waldorf and Statler

however the problem I have is that the body is currently off the chassis and won't be reunited for quite some time, so want to at least have some confidence that I wont be spending a grand on what will become scrap metal if there isnt the clearance to keep the wheel inside the body work. Not that my front end currently is representative of the finished article anyway, so that wont help!
Thanks for your help and concern folks most appriciated.

So your planning to run a 235 section tyre on a 9 inch rim on the front?...... or have i read that wrong?..... thats bloody big

That would need at least an et50 to get it anywhere near the same position as the original in the arch,but would have 50mm less clearance on the inside to the body?

Yes, in fact 235 all round, but a 235 slick is much wider than a 235 road tyre, by comparison the wets will be 235 Dunlop SP9000 road tyre which fit neatly onto an 8in rim, not the 9" that is recommended for the Dunlop 235 slick.

The convention seems to be that road tyres are measured at the widest point on the recommended rim (i.e. on the shoulder) and slicks are measured across the tread. That accounts for a difference of an inch or so.
