Comments please on the information below regarding ride quality as it
disagrees with my experiences.

Although those urethane bushings are great for longevity they are in
most cases of too high a durometer and have little compliance to absorb
road shock. Also those radial tyres do not help with obtaining a smooth
ride as the side wall are less compliant to vertical distortion. (bumps)
In a recent conversation with one of our T-Club members who happens to
be a tyre designer by profession, he noted that the worst thing you can
do to a T Car suspension components is to change to radial tyres.
Everyone who changes to radials, expound the attributes of, "a better
ride", when in fact the radial tyre just tracks and corners better than
a bias tyre, but loads up the suspension more.
Give me the good old bias ply tyre and have fun doing 4 wheel drifts.

Blake:
It's my understanding that the urethane bushes tend to harden and crack in a
relatively short time. I've been told the same holds particularly true of
nylon bushes, by one of the really old established front-end experts in our
area, who says they don't stand up well to changes in heat and cold, and
vibration .
As to the radials on "T" cars.....does this apply to TD's as well?

I would believe that old Saw about Radials verses Bias ply but as an owner
of a TD for 34 years and very familiar with MGA and MGB front suspensions
which are virtually the same even down to the fact that the spring pans and
lower "A" frame arms are interchangeable, and the factory went to radials in
the late 60's!!! As for poly bushes I have installed the Moss rear spring
bushes and love them, they firmed up the rear and last a lot longer than the
stock rubber ones, as for the front I use the "V8" bushes which in
reproduction are not as nicely made as the "Original" factory ones but they
still firm up the front nicely and last a zillion times longer than the stock
rubber ones, and you still have your fillings in your teeth
I installed Radials on the TD in 1973 and feel that it was one of the
singular best thing I did to the car.

Bullwinkle,
MG TD's and TF's and MGA's are transformed into
wonderful driving machines by installing radial tyres.
There is little difference in the suspensions of these
cars as to the newer MGB's which the factory fits with
radials.
The stock rubber bushings are great, as long as they
are in good shape.
Don't install nylon bushes in a Lotus Eleven. You will
soon sit on your kidneys or drive off the track. Some
cars require a small amount of "slop" to be
comfortable drivers.
I don't think radials would help TA-TC's. Besides, I
don't even know if anyone has ever made one to fit.
If you worry that radials will make you loose that
4-wheel drift ability, just make sure you get a low
profile tire and put air in it. My 72 year old Dad
has 275-35-18 tires on his Mercedes 500SL and it
drifts! Thats whats on front. In the rear they're even
bigger!
Anybody who says radials will screw up handling on a
non-radial car hasn't tried them. I have. They always
work better for me.
