MGBGTV8 wheel arch dimensions

Front wheel arch

Rear wheel arch
Gordon Hesketh-Jones sent in an email saying "following Chris Armitage's useful V8NOTE369, I am fitting rubber bumper 1800 rear springs and MOSS anti-tramp bars to my chrome bumper MGBGTV8 but I was disappointed to see that the rear end of the car is still much lower than the front. This "rear-droop" is exacerbated because when I fitted the new front cross-member earlier this year, I also fitted new front springs and these make the front quite a bit higher than before. I plan to send the old V8-spec springs off to Brost & Co for
re-tempering, resetting to the softer weight, and reshaping to correct the "rear droop", but need to know what to ask them to do. Do you know if there is any published information on the height of the back end, measured from the floor to either the stainless steel trim strip, or to the bottom of the wheelarch? Or ANYTHING? If nothing is written anywhere, could I ask you to measure your car and let me have the details."

I attach a note of the measurements I have taken on my car which show the current position on my chrome bumper MGBGTV8. I measured the distance between the top of the tyre and the underside of the centre of the wheel arch lip using a spirit level and steel rule as:
Front = 2.5 inches
Back = 0.0 inches (virtually level)

Check (refer to the attached diagram for dimensions):
Rear wheel: 24.0 inches less 11.625 inches = 12.375 inches = top half of the wheel/tyre uncompressed
Front wheel: 26.25 inches less (11.375 inches plus 12.375 inches) = 2.5 inches which ties up with my measurement

I have assumed the uncompressed half of the wheel will be the same front and back = 12.375 inches. I hope this will be of some help. The diagram with the measurements and the two photos above are available as a PDF which you can download.
