after reading magazine after magazine i have seen many different types of LSD's. but i dont know which ones are better or worse. for example i have seen 'Vicious' 'Helical' and now 'Active Yaw Control' so i was just wondering which ones are better and how they are better than another and if there are any other types out there.

Thanks

Quaife makes some of the best reasonably-priced differentials out there...however, there is no such thing as a 'Vicious' differential...you meant viscous, maybe?[IMG]i/expressions/face-icon-small-confused.gif[/IMG]

This is one very crucial component, as it can either improve your car's handling exponentially, or ruin it altogether. There is no absolute best type, as different types of differentials are better suited to certain conditions and your driving habits and requirements play a big role here.

From personal experience, I have found the Quaife LSD to be a very good all-around FWD differential (I had it on a VW Corrado and a VW Jetta VR6) and would highly recommend it.

This is a torque-biasing design which eliminates the need for clutch packs and is very reliable and transparent in every day use. Not cheap at all but worth its price...sadly, Quaife doesn't make one for our cars yet.[IMG]i/expressions/face-icon-small-sad.gif[/IMG]

This would be a good primer on understanding the various differential types and how they work.

Silver2k1Dood is mostly right, except for one thing: Quaife does in fact make one of their Automatic-Torque-Biasing Differential for our cars, check out my thread from a while ago about it Supposedly Quaife has an ATB Diff for us...! it has all the juicy details.

you won't need it unless u are runnin g a lot of torque...but if u r then your FF will become just as fast as a AWD ...i've know ppl that has it on there FF
GS-turbo..it can launch at 6k rpm at the track just like awd gsx's

Slikor, thanks a bunch for the link dood...I definitely will get this ATB diff ASAP...you wouldn't happen to know if there are cylinder sleeves out for our cars would ya?

no prob, Silver i sure as hell want that diff too, it'd be very nice. sorry, man, i dunno about the cylinder sleeves though

if anyone ever gets this ATB Diff, i hope they will let us know so we can know how much the install would cost exactly, and how it works, and stuff like that cause its gonna be a $1000-$1200 investment easy...but i think it'd be worth it

Heh...the Quaife for my old Corrado was $2800 installed...and worth every penny! that thing used to go through front tires like they were being given away--superchargers are fun![IMG]i/expressions/laugh2.gif[/IMG][IMG]i/expressions/laugh2.gif[/IMG] The one for my old Jetta VR6 was about $1800 installed, so $12-1300 doesn't seem excessive for the 'vic...especially since I want some sort of FI on it.

The cool thing is that slowly but surely internal engine parts keep coming out...there are cams, rods, and valve retainers now available; we just need the pistons and sleeves and the road will be paved for a boosted 7th gen.
