Hi Scott,
=C2=A0

I=E2=80=99ve run both a welded diff in the #114 (Dads car) and a Quaiffe in=
 the #80. =C2=A0On the same track, I find high speed sweeper corner speed i=
s much better with the Quaiffe as the welded diff requires modulating the t=
hrottle to control the forced oversteer, where the quaife car is flat out=
=2E =C2=A0Last turn at Thompson, the #80 was 11mph faster exiting the corne=
r with the same driver. =C2=A0 However, on the hairpin, the welded diff was=
 a much better performer where the quaife required a VERY smooth line and w=
as modulating wheel spin where the welded diff just rotated the car and sho=
t out of a turn. =C2=A0 I=E2=80=99ve developed a simple questionnaire to he=
lp. =C2=A0Lap times were the same on both cars.

=C2=A0

1. =C2=A0Do you drive like a madman? =C2=A0If yes, run the welded diff

2. Are you a smooth driver? =C2=A0If yes, the quaife rewards smoothness. =

I have not driven a Gripper diff

I hope that helps!

Scott,

Just my two cents worth (no cash value), but we have a Detroit locker in th=
e TR3 and my wife runs a welded diff in the TR6. I raced both this weekend =
at RA, and frankly don't notice any difference except in the pits or pushin=
g the car. Bear in mind that neither us, nor our cars have ever been descri=

 open diff, as it lifts the inside rear and loses drive.=C2=A0
