I'm curious what is the most aggressive differential that can be used on the street? A friend is hooking up his car with a competitive differential that he claims is rated at 80% (is that even a LSD measurement??) and we have a feeling it's going to have big problems on the freeway having the back end too loose. Anyone know what's a reasonable LSD for daily driving? Thanks

 

The true high-quality Limited Slip are supplied by Kaaz and Cusco and are much more controllable, having a wider, more progressive lock-up and better positive lock up at the limit. They are more streetable because it won't suddenly spin you around in low traction conditions such as rain and snow. You can, but you can also be in control...

but what do i know...
and i dont think % is a measurement
edgar,

 

80% what? 2-way diffs are perfectly streetable.

 

80% probably means differential locking percentage.

This is a fixed number on a traditional clutch-type diff.

 

did you mean GEAR ratio?

or diff type?

in the 4 wheeling world, there is a type of TRACTION AIDING DIFF called USER SELECTABLE.

on my truck, i have an ARB AIR locker. this locker is 100% spool when activated. when deactivated, it acts like a open diff.

ARB needs and air source.

there are ELECTRICAL lockers too. just a +12v source to go 100% spool. and then back to open diff.

next up is the detroit locker. automatic lockup. but when needed it will release on the most opportune time.

do these count?

 

Most 2-way diffs I'm familiar with (tomei/kaaz/cusco/ats) are all 100% locking by default although I suppose you could turn it down by editing the discs.

 

ok I talked to my friend again, his bimmer is going to have a Kaaz LSD in a couple weeks with 80% lockup, 1.5 way slip. apparently this is "very aggressive" and other 3-series owners have installed 50% lockup and found that setup to be very aggressive for street driving. should be an interesting project

 

Hehe, very aggressive

 

he bought a set of sparco torino seats in white/black too, but he's run out of money so i get one for 400 bucks i'm very excited

 

my friend has a welded rear diff.. he drives a 240 though. he also loves to drive it around it makes a wonderful daily driver.

 

your friend must buy a lot of rear tires too... lol.....

 

how are they not spools if they're 100% locked?

 

What?
