For road racing, weight high up and towards the front is the top priority.
For TR2 & 3 vintage racers, the first 555 TR2s built had alloy bonnets and
boot lids fitted as standard, so these have always been legal, if you can
find them. I spent thousands of hours taking weight off our TR3, and with
SCCA safety equipment, it was down to 1700 lbs. Many fuel cell regs. allow
moving from the standard location, so it is a good example of moving
required items to lower the CG and polar moment.
Feel free to send a copy of your list.
In terms of safety, there is no safer way to race than jumping into the lead
and then extending it.
TR Regards,
Hardy

Amici -
As I have proceeded through Barnie's - 1959 TR3A - evolutionary process
from a derelict barn-find to a vintage racer over the last two years, one
of the initial questions that I was faced with was related to the issue of
weight reduction. The question of how much and where could I reduce the
weight and remain compliant with the requirements for originality of the
majority of vintage racing organizations, while not compromising either
safety or performance, was forefront in making decisions. So things like
the addition of fiberglass components, changing the frame to a TR4,
increasing the width of the fenders or the addition of flares were not
considered.
What
I was looking for were areas that I could substitute alloy components for
stock iron ones, use of components that were available on later models of
the TR3 line and offered weight saving options. Over the last two years I
have been able to reduce the weight by 104 pounds simply by acquiring
bolt-on parts. Of course knowing what is available, its source and cost has
been the key and I have to thank many from this list for that knowledge.
The 104 pounds was achieved in the following major component breakdown:
Engine - 61.0 lbs
Chassis - 11.0 lbs
Front Suspension - 16.0 lbs.
Rear Suspension - 16.0 lbs.
In addition to the weight reduction that was achieved, many of the
components offered additional benefits in terms of safety and performance.
I have prepared a component by component table showing how and where this
reduction in weight was achieved, however it is much too long for team.net
therefore if anyone would like to receive a copy please just ask and I will
forward one immediately _______________________________________________
