same time.

I have been trying to find out exactly what
gives the Rover I have its feeling of instability at high
speeds. We have had the car on the Skid Pan. The roll ratings
does not seem to be unduly low, and the car appears to under-
steer by just the right amount, so one, therefore, concludes
that the trouble must be either steering geometry, or shock
absorber characteristic. Would you consider trying out a
set of Gordon Armstrong dampers on a Rover ? We have been
doing a certain amount of development work on these shock
absorbers, and they can certainly be made to hold the axles
on the road.

I would like to come over to Coventry when I get
back from my holiday, which will be after September 25th.
Could you let me know if this would be convenient, and if so,
on what date you and your brother are likely to be at the
factory ?

Yours sincerely,
