I have a small request to make, chaps.
For reasons best known to MMC, when they built my car back in 1986 they cut the wings extraordinarily tight to the body - so much so that the tyres actually stick out further than the wings at the rear. Only by a few mm, but it's annoyed me for the last 17 years or so.
I'm currently planning to replace the wings, so now's my chance to get it right. Could I therefore possibly ask any of you trad owners to have a look at your cars and tell me how much your rear wings overhang the tyres?
The easiest way to take the mreasurement is to hang a length of weighted string from the top centre of the wing, and then just use a ruler to measure the distance from the string to the fattest part of the tyre. I don't mind if you use imperial or metric units. I don't think it will matter what width tyres you have, it's not the overall wing width I'm interested, just the overhang.
I reckon it should be around 12 - 18mm or so. I want to get the wings far enough out to reduce spray in heavy rain, but not so far as the tyres look lost in the arches. I reckon if I take the average of all your measurements I'll be about right.
TIA
