DON - on my +8 I have decambered the front to 0 degrees.  This was done on the 
recommendation of a Morgan racing specialist in the UK (MacDonald if I recall - 
I bought the lower plates and other bits from them) who recommended 0 degrees 
for early +8s.  Don't know what the consensus is for 4/4s, sounds like a good 
question to toss out to the masses, pretty quiet out there anyway!  I have no 
complaints about my car turning in, the steering seems no different from my 
original stock/street setup, and I've had no abnormal tire wear. One thing you 
MUST do is change your tie-rod as the old one will be too short.  In my mind at 
least, there will not be enough "meat" of the tie-rod ends in the old tie-rod.  
The old tie-rod is, I believe, about 38 1/4" long.  You need one about an inch 
(maybe 7/8ths) longer.  A man of your experience will probably make his own but 
you can buy a "long +8" tie-rod.  Naturally this is too long and you will have 
to shorten it in a lathe!  Measure twice, cut once!

I'm sure too you will want to install what they call "brake reaction torque 
bars".  Your old SS may have even had them.  Much like the tube/bar running 
from the bottom of the stub axle/spindle back to the chassis, the BRTB is a 
piece of tubing, one end of which is secured under the kingpin oiling bolt, 
then running at an angle back down to the chassis in front of the wheel stop 
blocks.  Again, you can buy these all powder-coated and pretty, or make you own.

Getting back to decambering, I seem to remember someone (maybe it was 
Freshman's  "Baby Doll") actually had an adjustable system.  I often wondered 
if a Morgan really responds to such high-tech tuneability.  I've always thought 
of the Morgan as a poster boy for "Close enough for government work".  This is 
no complaint, just part of its charm!

Cheers for now, Craig

I, and several of my morgan racing friends had our spidles heat treated 
during the early 60`s. We all had +4s, mine was an SS.  The results were (a) 
no more spindle flex pushing the pads back and creating a loss of brakes. (b) 
no more broken spindles. 
Spindle breakage was a very common problem in those days.  After the heat 
treatment there was never another broken spindle even when a friend flipped 
his car at Lime Rock and landed it on the LF wheel.  As you surely know, the 
folks at Morgan knew little of metallurgy in those days.  The spindles and 
the rear axles (using posi tract) were a constant problem until properly 
treated.  They would not even register on a brinell tester.  I have the 
spindles off my car in the process of decambering and was wondering whether 
to have them treated or convert to the +8 units.  It sounds as though the 
hubs would also require upgrading and it would surely be less expensive to 
heat treat.  In 1962 New York it cost $6.00 each. No doubt that has changed 
but I imagine that $50 would do it. It may not even be necesary with the 4/4.
While we are here - have you decambered your car?  I bought Hoosier Vintage 
GT tyres, on your recommendation, and think that they should stand pretty 
strait up. I see a lot of cars with serious decamber, on the order of 2 
degrees, and think that would be rather much.  I was planning on one degree 
and would appreciate our input.

Cheers!
