We had a rainstorm last week & while driving through a puddle at about 45 the right side hydroplaned badly (left side was clear of the puddle) and the steering wheel tugged hard to the right. If I were going faster & not paying attention it might have been dangerous. If I were driving FWD I guess it would have sucked even more. The US WRX only has rear diff LSD (correct?)

Was wondering if a Front LSD would help you handle the car better through situations like that, or make it worse?
Since the LSD would direct power to the non-hydroplaning side wouldn't the tendency to spin out be more? Or would more power still be directed to the rears to balance it out?

i'm pretty sure we have a fron LSD...and no, i don't think it would help any...

when you hydroplane, and the front end starts drifting...that means nothing is holding you to the road. it doesn't matter if you have electronic traction control... if you're hydroplaning, there's only one solution: slow down! :)

We do not have a front LSD. New tires would help you the most with hydroplaning if you're still running the RE92s.

The front LSD is going to make you more likely to understeer thru a turn because if you get on it and spin a wheel it's going to lock and send you straight. If you sitll haev RE92's GET RID OF THOSE THINGS!!! Get a Set of Yokohama A520's

If you're hydroplaning like most people do, which is in the left lane of a highway, where only your left wheels hit the water because that's where all the water's collecting, then yes, a front LSD would help.

Whenever I hydroplane, I make sure not to hit the brakes (I don't have ABS). I just let the car coast and slow down by itself.

THe last time I hit the brakes when hydroplaning (ok, it was actually slush, not water), my Honda Civic did a 360 across the highway and into the shoulder. Fortunately it was early morning and there wasn't much traffic.

A front LSD won't make you understeer more.. especially not a good one like a Quaife. Power transfers to the wheel that's not slipping, thereby pulling the car around the corner. Not straightening it out so it can go over a curb into a hedge. :rolleyes:

OR: Learn to drift! Rainy days in parking lots are best.

A front LSD will for sure improve cornering. I don't know about hydroplaning, because if there is no traction the LSD can't do much; it would'nt mak it worse...

:alien: I think that LSD would made it hard to drive in the rain period, so if you start hydroplaning you short :lol: .......J/K

The real answer you are probably looking for is, a limited slip will not help hydroplaning, in fact it would most likely make it worse

Won't help with hydroplaning but WILL help inmensely with handling. I am going to use a Kaaz front dif myself.

Fubaru....are you sure you hydroplaned? That yank to the right was just your wheel slowing down when it plowed into the water. When you hydroplane, the steering gets light and loose (like being on ice) since your tires are on top of the water.

to stop that pulling in a puddle all you have to do is travel with your car to a place where the laws of physics dont apply:)

Hi,
If the car was hydroplaning, it was same as flying
LSD or not, it won't make any difference. Adjust
your speed to the weather condition and if and when you really get hydroplaning, never hit brake,
just slow down(foot off gas pedal). If you lost control on a ice patch, LSD may help.
No matter what, one's drving skill is most important. If you live where it rains a lot, I'd
get a set of good tires to minimize the chance.

Like beethoven said, are you sure you hydroplaned? I've driven in a lot of rain with my OBS, with OEM BF Goodrich tires, and have never hydroplaned. Could've just been the force of the water pulling you.

take a real driving course ($300 to $1000). out at sears point, Jim Russel has a 1 day driving course where they teach things like how to drive properly when the car hydroplanes, and other things. I believe its called highway safety. They also have a cheaper course for teenagers, but I think you learn the same.
I do not yet have enough money to take the course.
