LSD in layman's terms?
- Thread starter TriedandTested
- Start date
In FWD the weight is over the driven wheels, coupled with the lower power and torque outputs means that an LSD is less likely to be required
My piddly 1.8 drop top has an LSD
You sure? I can't see mention of any 9-3s having LSDs. I'm interested to know as my dad has one. Can you provide me with a link showing which ones have an LSD?
Totally wrong
Example
1.8 vti has LSD
EP3 civic type R does not have LSD
JDM EP3 has an LSD, and that is of course what I was talking about.
It's an MB6 you have, never heard of these with a diff, or any UK Civic other than the limited space ship thing.
Most understeer on a fwd car is not caused by the inside wheel spinning it is caused by entering the corner too fast and an LSD will do zip all for that, as the slip is on the outside wheel anyway, however, with some more drive to it, it may help you power thru it, personally I lift off and let the back do the work in those cases
Sorry I was replying to the first part of your post. I have an MX5, not a Saab.

Nice when you can totally ignore the effects of slip angles that make it more significant on a FWD.
Because a 1L 48bhp Micra is going to be ragged about on a track or on the road to require the LSD ....
LSD is for the more "serious" cars, most FWD cars are a joke. Some FWD cars rightly have an LSD, but that is because they are actually of use as the car has at least some performance
So's your face.
No I had an MB6 and a MC2 and these both had LSD
At the moment I have an Accord Type R with LSD
Someone makes a valid point and you're comeback argument is that every FWD car is comparable to a 1L 48BHP Micra! lol
Start posting facts before people start to think you're the joke!
Just because you think most are a joke doesn't mean some don't need an LSD. You can't write off every fWD car with your sweeping statement.

I clearly said "MOST FWD", I did not say all FWD cars.
Normally when thinking of LSDs I just think of RWD. FWD + LSD... it just doesn't compute very well for me. FWD has become a bit of a black art these days with all this "revo-knuckle" and what not.
An open-diff just sends the power to which ever wheel will accept it most easily. So if a wheel starts spinning the open-diff will just keep sending more power to it. Pretty dumb really but for most cars it is fine. An LSD on the other hand will not send as much power to the spinning wheel - but will send it more power to the other wheel. Therefore it keeps traction more balanced and predictable for the driver.

Calling a differential dumb really doesn't do justice to what is a fantastic piece of engineering. How someone came up with it really is beyond me.
Well yeah. Didn't mean it quite like that. But compared to a LSD, an open-diff is quite dumb
No disrespect to the inventor of the open-diff Well yeah. Didn't mean it quite like that. But compared to a LSD, an open-diff is quite dumb
He (or she) died thousands of years ago, so I'm sure that they'll get over it
