I went for a run in my car last night, did around 40 miles , everything was fine.

On the way home there was a very light shower that left the road very slightly damp, just patches or darker tarmac.

As a came out of a juntion in second gear the car took a pretty major side step and was not far from a spin.
I know i can do that if i try, but this was out of the blue and thankfully the road was dead queit because I was on the wrong side of the road for a few secs.

(might better with washable seats)

I gave me something to think about as I had been pushing it into some tight corners and accelerating quite hard just a few mins before.

The tyres a Yokahama 538 and pressure is 20lbs

Its it the LSD causing this?.
Would I be better off with a non LSD for road driving as I am unlikly to get near a track.

i have a lsd and i would say yes, i get the same problem

however on the other hands its a lot of fun and its controlable.

I think that an open diff is more likely to give wheel spin off the line or in tight corners than an LSD. The effect is that you don't accelerate but you don't spin. An LSD will give you acceleration through the wheel that has grip, but if you lose that one as well, you get oversteer or even a spin. That is how it seems to be in my LSD equipped car.

20 PSI might be slightly on the high side. perhaps a bit less would give more grip before you lose traction.

if its a an ATB diff, which I have had in a front drive road car the are great for exiting corners. problem is they send power to the wheel with the most grip. If there is no grip you still won't get any traction.
I also had a rather large moment in the wet on the way to Stoneleigh, choice was concrete wall or wire fence. I chose the fish tail option and very nearly brown trousers.
I'm not sure an LSD will help in the damp. dry yes.

In my experience of my Cobra with an open diff and tons of power and torque I get into a lot fewer loss of control situations than my friends with similar power and LSD's.

On the dragstrip their cars often sidestep causing much consternation to themselves and the wall or car next door that they are heading for and an instant lift leaving me the winner at the end of the strip.

I just have to keep traction through a gentle progression on the accelerator and even if I do break traction my car runs reasonably true and if I want I can go into beautifull and very elegant and satisfying power slides - something I notice that the LSD equiped cars struggle with.

Almost certainly. LSD sends torque to the wheel that still has grip, giving you an unequal 'push' and hence rear steer. Non-LSD just spins the wheel with no grip and sends bugger all to the wheel with grip = no rear steer but no fwd motion either!

lsd tends to do this, yes
