Subject: [928] Racing 928 at the track. 5 points to be successful

1.  gut the back end of the car , and get down to at least 3050 lbs
2.  dont run in any series that forces you to use 7" rims!! (totally unfair
for a 3400lb car to compete with 944s that have 8s and 7s) 9s are fine
front and back  Use 275 40s on the rear and 255 40s on the front, kumos.
(yes they fit fine, as I raced on my 7 and 9s for over 3 years, but I had
to use 245 45s in front due to my 7.5" front C2 rim)
3.  add roll bar and harnesses
4.  stock suspension replacement of the eichbacks and bilstiens is what i
used.  (only .3seconds faster at sears for the full race supension, thought
it was .8seconds, but checked the times)
5.  266rwhp is good enough to do some real damage at the track.   its not
about HP, its about weight in the 928.
I ran 1:45.1 out at Laguna with stock brakes, mismatche suspension, and
235hp RWHP on Kumos, but at 3000lbs.   That would be a lot faster than most
all of the porsches that are driven the track, and certainly all 928s . 
(ie prepared, improved, or stock), 

Even 500 hp 928s have a hard time at the track if they have 3300lbs or
more. Its all about HP to weight for accel and decel (ie brakes to weight )
  and dont forget cornering speed capability.  Ill run circles around any
3400 500hp 928 on a road course.   

Have fun,
