Hey guys.... this maybe a real stupid question...but does our 3rd Gen cars have an LSD stock??? Or is this something we have to buy and attach aftermarket?? I know we have a rear differential....but is that the LSD???
Thanks guys...

 

Yes it is an LSD. Most people upgrade for dragracing since ours don't seem to be up to the task of high rpm launches.

 

LSD = Limited Slip Differential

FD's have a Thorsen type limited slip. This type has spider gears that transfer the power to both rear axles.

As stated above, many whom drag race are forced to switch to a clutch type differential, as the stock thorsens will brake under high RPM launching. I broke 3 spider gears on a 5500 RPM launch on ET streets.

The 87-88 Turbo II had clutch type LSDs that swap directly into FD rear ends and are perported to be a strong as the KAAZ aftermarket LSDs. I just installed one but have yet to test it out.

 

hMMM.... Then why did mazda swaped the clutch type to Thorsen type??
Is there an advantage towards the thorsen type lsd's??

 

Just as a small nit-picky correction, it's actually a Torsen LSD (not thorsen), and it uses helical planetary gears

 

The engagement is smoother and more predictable. They didnt really plan on having 400+whp launches on slicks in the equation...

that said, i broke 2 diffs, one on the street and one on the track (6.7-7k launch on etstreets = broken) and have sense installed a TII unit...I have yet to test it out at the track (or do any type of burnouts or anything sense) because i decided to change the setup of my car..again...

 

lol^^^again...hahaha

 

Shut up you *****.... thats why there is a forum where you can ask right? By the way... I did do the search as well.

 

The Torsen is better for roadracing. The response is quicker and more linear, for better grip during cornering.

-s-

 

wait...am i the *****?

 

Yea, I didn't understand where that came from either.

 

ok just making sure i wasnt the only clueless one..
