Tons of LSD questions... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok, now that I've got the suspension and tires fairly sorted out and pads and rotors on order, I'm planning on ordering a limited slip within the next two months. The open rear end is really starting to slow me down at autocrosses, and the inside tire just goes up in smoke instead of pushing the car. I don't want a factory VLSD, don't ask me why. KAAZ seems to have a big following, and I hear the clutch packs are bigger than everybody elses, so that's what I'm going with. I plan on using the car for auto-x as well drifting, so I'm aiming for middle-ground between grip and drift.

Everybody seems to reccomend the 2-way over the 1.5, but this doesn't make sense to me, either for drifting or auto-x. It seems like it will just increase understeer on corner entry unless you dial in some radical suspension and alignment settings to break the rear loose under decelleration, which will only make the car a handfull when powering out of the corner. In which case, what's the point? It must work because most drifters use a 2-way, but I'm afraid I just don't understand the concept.

This may seem like a stupid question, but do the instructions come in English? I ask this because my Tein instructions weren't. I plan on having a friend of my dad's who owns a rear-end shop do the install because I know it's a bitch, but he's used to doing solid-axle cars and trucks, and I'm unsure how different this will be for him, so I would like instructions for him.

I guess you adjust to the limited-slip effect by removing clutch plates before assembling the unit. How many plates should I take out? I don't wan't the tires scrubbing during parking lot manevers. I figure if having all the plates means near 100% lockup, if I divide the the radius of the inside tire by the radius of the outide tire during full lock turning and multiply by the total number of clutches, it should be fine. So if the outside radius is 20 feet and the inside is 15, 15 PI squared / 20 PI squared = 0.56 or 56% difference, so I would remove around 56% of the clutches. Or is this total crap and I have no idea what I'm talking about?

And finally, where should I order it from? Any killer deals going on out there? Any help would be appreciated. Thanks in advance. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>
