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?

On the subject of "lifting". I AXed a 914 with a rear AR bar for a couple passes. I think I took it places where the owner hadn't gone. We were making fun around a sweeper feeling good when the inside rear lifted.....acceleration ceased (open diff)
and the cars well behaved attitude went to hell....then got worse when that inside rear sat back down....I really can't describe the move except to say that it got ugly trying to catch up with it. I can't help but feel that a clutch type LSD wouldn't have made it any better than the open diff action of the TB. *Fix the suspension first* if you're "lifting". At one point the shitbox went thru a "smoke the inside rear" around a corner with an open diff (no rear AR bar). I kept jacking up the rear spring rate & adjusting the front AR bar to suit untill it quit that action. I really don't give a damn which LSD anyone else uses. The data is in this thread. Pick your poison. A pic...note the single circular black line on the left behind the car. Attached image(s) ![]() |
