I dunno if you were refering to me, but I will give my $0.02 on setups and tires.
I am still on my original set of TO27's, (approximately 5 race days on them) and can really notice the fall off in times now. I will probably pick up another set soon, but with me moving into my new house this past week, who knows what i will be able to do or afford.
as for setups, i have had the best luck with the baker setup with a rear droop of 7 instead of 5.
I tried the spool/rear shock tower setup from one of baker's setup sheets (yea i know it was for asphalt, but i wanted to try it

) it was easy and consistent, but overall too slow. I threw the one-way back in and was back on pace. note that setup had lots of steering so i ended up dialing some out on the radio.
what i ran just this past weekend was:
front
------
60wt
gold
2* kickup/2* caster blocks
5mm rideheight
shock position - middle on normal front tower, inner on arm
camber link - upper inner
std anti-sway bar
oneway
droop 7
rear
------
50wt
blue
3* toe-in/0* kickup
short wheelbase
camber link - upper inner, outer on hub
shock position - middle on tower, outer on arm
std anti-sway bar
battery to the rear
droop 7
normally this hooks up really good for me, but last sunday it was a lil out of control. it would oversteer coming in and push coming out... not predictablly (sp?) it would just happen all of a sudden, but with as many runs as i have on these tires, i think it was just the tires causing most of my issues.
what is everyone else running for tc3 setups?
