Hi Mike.=C2=A0 I won The June Sprints at Road America in 1989 and 1991 wit=
h my TR-4.=C2=A0 I used a 4.3 rear end gear and a close ratio (Dolomite) ge=
arbox with overdrive.=C2=A0 Same set-up I used at Road Atlanta for The Runo=
ffs.=C2=A0 The 4.3 gives a good gear for the tight corners (turn 5 and Cana=
da corner) and the overdrive gave me plenty of top end.=C2=A0 Of course my =
red line was a little higher than yours (7.000) so you might have to adjust=
accordingly.=C2=A0 Good luck.
