I like a hoop under the cowling tied to a rear hoop with side bars, and the
support bars for the rear hoop connecting to the end of the rear spring
mount. I also added a short pipe and flange from the cowl hoop to the
firewall on each side, creating a hard point. To that hard point I could
bolt in bars on each side that connect to the upper shock tower, bracing the
entire frame from front suspension to rear. If a sanctioning body gets
sideways you can unbolt the bars, but none ever did.
This is a very safe cage design and it stiffens the frame wonderfully. TR3
frames are as wobbly as noodles otherwise. Did you edge weld the frame? You
can do that without adding an ounce--just fuse the edges of the stampings
with an acetylene torch. Makes the frame quite a bit stiffer, the spot welds
permit some flex.

My 2 cents.
I have to run 14x6 rims in SCCA ITB with the Alfa, (Sorry guys!) I run the
Hoosier R3S04's. I've tried 205-55-14 and 225 50-14. Both sizes are a real
bitch to get on the 6" rim due to sidewall stiffness. My times are at least
1 second a lap faster with the 225-50-14. This 1 second a lap was on the
long course at Pocono. Lime Rock I gained about .5 seconds. The Hoosier
sales rep said the same to me that Goodyear said to Mr. Kastner. But I
don't think the time clock lies! If body clearance is a problem a possible
solution is a wheel with a slightly different offset.
TR3A Quick update:
Gussets have been welded to the frame, New floor boards are in. Just
finishing up the other minor inner body repairs. Next step: Sandblasting
and Roll cage design. Any ideas?
