Interesting to read Tony=E2=80=99s comments, because my experience is =
generally the opposite.  Guess that=E2=80=99s why there are choices in =
the market.
I ran the toyo R88Rs for years on my GT6 - 205/60-13s - and decided to =
try the Speedsters when they started making them in 13s several years =
ago.  I find they are much more consistent - they don=E2=80=99t get =
greasy halfway through a session in warmer weather which the Toyos did =
for me.  For the Toyos, about 15-20 minutes into a session, going =
=E2=80=9Coff" was a consistent issue.  I find the breakaway is more =
consistent too. My lap times are a hair better, 0.5 to maybe 1.0 seconds =
- with the Hoosiers. =20

That said, I=E2=80=99m running 13" wheels in an 1850 lb car and you are =
running 15=E2=80=99s on a car that is probably not much heavier, so your =
tires may have an easier job of it.  As you know, I work the GT6 pretty =
hard.  For me, the consistency throughout the race is worth it, but Tony =
is right - they certainly wear out more quickly.  I figure the =
Speedsters give me about a season (5 weekends), and then they become the =
second set on my spare wheels for practice sessions, etc.  I used to get =
the Toyos shaved and even then it was tough to wear out the rubber, but =
at a certain point they had just been through too many heat cycles to be =
usable anymore.  The Speedsters have a softer compound, no question.

In the 13s, the price diff is about $70/tire.  Only one way to find out =
- get a set and give them a try!

Alternator - not sure how easily they adapt to the TR6 mounting, but I =
run a 55 amp Denso alternator that I think was originally spec=E2=80=99d =
for an Isuzu - pretty common.  Pep Boys under $100.  Can be wired as a =
one wire set up, plus the output cable.  I was able to use the block =
mounted bracket with a long bolt to hang the alternator out front =
(single shear mount) and a lower strut supporting the adjustable bracket =
from further down on the block.  I run cogged belts so there=E2=80=99s =
not the tension issue.  I=E2=80=99ll dig the spare out and find the =
number, but it=E2=80=99s definitely not quite a bolt in swap.
