Purpose of the car, in order:
Spirited street driving, occasional AX, occasional track days. Here's what i think i know (IMG:style_emoticons/default/biggrin.gif) LSD - Always locks wheels together under acceleration and deceleration. - Introduces understeer in slow corners. - Generally considered the better choice for the big track. TB - Only locks wheels under acceleration. - Acts like a open diff if a driving wheel is off the ground. So, the question is, what should i get for my 915??? The car will never be a dedicated track car, it's mostly driven on the street. The TB seems to be easier to drive on the street. However, the slow corner understeer of a LSD could probably be tuned down with suspension settings. The TB loses it's magick if one wheel is off the ground. In an AX setting, the suspension would need to be pretty stiff to keep both wheels on the ground at all times, would a LSD be the better choice here? Anyone compared the two back to back in a 914?

I used the TB diff in my AXer If you lift the inside rear, it does act like an open diff....I hear....never done it. The TB diff transfers the power to the wheel with the most grip ( even if the inside rear is just lightly loaded) and you can feel it happen.....the car tucks tighter into a corner. If you're lifting the inside rear your suspension settings are not even close to right and you should fix that before you think about an LSD. The TB was recommended to me for AX by Fordahl, Burfield, & Guard amongst others. Nobody recommended a clutch type.
I have a TB (stock) in my MR2 turbo also. It is seamless on the street and has no problems with AX.....all stock suspension with no inside rear wheel lift....even with a rear anti roll bar.....of course AAR set that car up for Toyoda so it figures. |
