| 495 Wheel 
arch dimensions for a chrome bumper MGBGTV8
 Gordon 
Hesketh-Jones sent in an email to the editor 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."

Smith responded with an email to Gordon saying "I attach 
a note with a diagram of the measurements I have taken which show the current 
position on my chrome bumper MGBGTV8. I measured the distance between the top 
of the front tyre and the underside of the centre of the front wheel arch lip 
using a spirit level and steel rule as:
 
 |  Front 
wheel arch
 
 
  
 Front 
wheel = 2.5 inches
 Back wheel = 0.0 inches (virtually level)
 |  Rear 
wheel arch
 
 Check 
(refer to the attached diagram for dimensions):
 Back 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 alongside.
 
 I have assumed the 
uncompressed half of the tyre and 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.
