ride height

[3154tm]

was hoping someone in the group had an approximate
ride height for a '74 m chassis and where it's
measured from. also do the lower control arms
assume an angle relative to the lower chassis tubes
or are they in plane w/ them when the chassis is at
the correct ride height? thanks.

The M series was designed to have steering arms that were horizontal when the car was level, if you look at the chassis you can see what effort was put into raising the mounting position of the rack. This would have ensured minimum bump steer. The car was also designed to use the 15 inch 'finned' wheels and (big) tyres as used on the vixen. If you fit these wheels with high profile tyres and adjust the suspension ride heights you will find that these arms will be horizontal.

BUT in true TVR fashion the soon after production started the 15 inch wheels were substituted for the 14 inch T slots (or woolfrace if you paid the extra) with a lower profile tyre. These wheels require longer shockers to provide adequate ground clearance which puts the geometry out.


You can set up the car to keep the arms horizontal with 14inch wheels but you will find that you have a ground clearance of about three inches! I know I did it but soon got fed up of replacing the exhaust after ripping it off three times in Scotland in one weekend

i hope to use 15" rims, but with a 60 series tire
i don't think it will be enough. do you know if
anyone has used a steering arm/tie rod lever from
an earlier car. moss lists different part numbers
for each of the tr2,3,and 4s. is it possible that
one of these might not have as much drop as the tr5/6
part? thanks.
