So it is a cheap alternative to a proper lsd but its like anything you get what you pay for.

Your mistaken I'm afraid.

They don't have that effect, in fact the opposite effect. Go and jack up a VLSD equipped car and you will struggle to turn the wheel on its own.

If someone was to pratt around trying to drift all day then the viscous unit warms up. Its an energy absorber. Once its hot a worn unit won't have much resistance anymore. Just like butter.

Its a damn good modification. Its not geared towards drifting. If you want drift then spend £700 on a Nismo GT pro diff.

I am not saying its a bad thing I have driven both viscous lsd and mechanical lsd i was a bit dissapointed by the vlsd. You do need a good diff to launch your car in a straight line as well as to go round corners so its not just drifters that need good diffs. However in my book(student)a cheap and easy mod is a good mod.

The main thing which this diff does is eliminate single wheel spin when you don't want it.

I noticed the LSD's effect most when I removed it back to a standard diff, and was surprised how frequently it would then spin one wheel. This was with circa 240bhp.

I am not surprised I recently owned a bmw e30 325i and even with about 150bhp it would spin one wheel all day, wet, dry, straight line, corners you name it. Previous to that I had a 270 bhp TVR which actually went round corners without spinning one wheel ever although I did fishtail on the motorway at 70mph in the wet, fun but scary. As for the S12 untill it gets a manual conversion the diff is the least of my worries the auto is slower than I expected.
