Third Member Advice

[Goosesdad]

Going to purchase my third member, appreciate any advice.

Currie 9" Carrier with Baer Floater.
Tremec Magnum with 2.66/1st and .62/6th
Engine: Not purchased yet but LS-7 650ish
335's on 18's

Typical mix of driving. Street/autoX/road course.

So far seems like 3.89 is most recommended ratio vs 3.70?
Appears the Wavetrac has a lifetime warranty vs. Truetrac?
Operationally - Wavetrac vs.Truetrac?

Thanks!!!

I had 3.73 with the same t56 and 315/30/18r and found 6th gear was not really usable under 70 mph. That said I went too high and installed 4.10 not knowing better, but doing it again I'd go for 3.89. Only recommendation I'd have is make sure your typical city/highway speed limits aren't too close to your shift points. Might not be a big issue with your big hp engine, but with my setup in my hilly neighborhood I felt I was downshifting on hills when at the 25mph limit.

Thanks !! Good advice, I will likely go with the 3.89. Do you have any thoughts about Wavetrac vs. Truetrac?

I'm probably not the best person to ask since I was just looking for a zero/low maintenance system for street driving. I haven't had any issues or noise with my Tru-trac, so no complaints.

From my research it's a good thing the Wavetrac has a lifetime warranty because more people have problems with then than Truetrac.

Strange has the S-trac which is another option. That's what I went with.
