[DeTomaso] Wheel offset

[cengles at cox.net]

Dear Mark,


              I have one Pantera with front 17x9 and 245-17-45 (?) tires 
and 5 degrees positive caster.   The other one has 17 x 9 wheels (both 
wheels with offset and backspace per Pantera Performance Center specs) 
using 255-17-40 (?) tires and 4 degrees positive caster.

              Yes, the left front inner fender gets rubbed by the tire 
at low speed full lock parking lots maneuvers.  They have done so for 
about twenty years and it no big deal and is not an issue on the 
twisties.  What is an issue with those sizes and increased caster and 
stock fenders is the outside edge of the tire kissing the fender lip at 
about 10 o'clock on the left and 2 o'clock on the right.

              IMHO, I think that 18 x 9.5 wheels and appropriate tires 
plus the amount of increased caster for high speed stability would be 
the edge or slightly beyond what is possible.  I would think that 
physical modification of the fender would be required.  That has been 
done to mine and is very....discrete.

              Is this for ORR?


                            Warmest regards,  Chuck Engles
