I have weighed several TR6's and the last 2 sets of numbers are most
accurate.

Subject: TR6 F/R weight Dist - I FOUND THE ANSWER
AH HA !!
The number came from the November 1972 Car & Driver test of the TR6
(Front
50.5%/Rear 49.5%). I have a copy of "Triumph TR6 Gold Portfolio
1969-1976"
(Brooklands Books). Its a collection of reprinted magazine tests and
articles on the TR6. Also in that book is the February 1969 Road &
Track
test, which listed the F/R distribution as 51/49, the February 1969 Car
&
Driver test which listed 52.4/47.6, and the October 1976 Car & Driver
test
which listed it again as 50.5/49.5.
I hate it when I can't remember where I got a spec from. I guess no
matter
what figure you believe, the TR6 is not the totally nose heavy pig that
everyboby assumes. Of course, your mileage may vary.

Since its my site, I'll try to answer. I think that I got that number
out
of the Bentley TR250/TR6 Manual. I'll have to rummage through my books
to
find out for sure.

According to this site the front/rear weight distribution is
50.5%/49.5%.

I'm not sure where he gets the numbers. Can anyone confirm these
numbers?
These numbers do make sense if you study the car for the following
reasons:
1) Most of the engine is behind the front road wheels. Notice all that
empty
space in front of your radiator.
2) The front road wheels are set very far foward (which will reduce the
weight
place on the front road wheels).
3) The rear road wheels are set very far foward (right behind the seats)
which
places a good portion of weight squarely on the rear road wheels.
4) Heavy items (such as fuel cell and battery) are strategically placed
to
balance the weight between the front and rear road wheels.
Think about weight distribution as how much weight is sitting on each
road
wheel, regardless of where the road wheel is placed in the chassis of
the
motor car.
Based on the curb weight of 2375 lbs here are some calculations I ran to
determine the weight sitting on each road wheel when the car is at rest:
Front road wheel load: (2375 * 50.5%) / 2 = 599.6875 lbs
Rear road wheel load: (2375 * 49.5%) / 2 = 587.8125 lbs
Please correct me if you find any errors. I am a lowly programmer, not
a
mechanical engineer.
