Does anyone try this? Looks like very simple.

 

I heard its garbage

 

Why? Dosen't block or what?

 

whats excactly are the advantages of this? like LSD and non-LSD?

 

Close to. This fing can block your differntial for more positive start (on dragrace or in winter for example) but works little bit differ and less bloking power than LSD.

 

the springs look hell og cheap and what is that metal pice for......?

 

LSD...as in the pills they took back in the 60's? LOL!

 

There is no disadvantage to having and LSD. Most all higher end performance cars have LSD from the factory.

 

 

i mean will this add any power then? whats the purpose

 

put it bluntly - you'll burnout by two weels, not by one.

 

^ so your saying both tires will spin instead of one? that doesnt make sense, if i spin tires right now both them spin?

 

Depends on pavement: in ideal conditions on clear, dry and flat asphalt, good warm tires and right wheel rake you can slip both, our cars have good balance and axels length, but usually something is wrong in our lifes Most tiresome moment for me - on dragerace is changing first to second gear - tires begin to spin, but one of them usually looses mesh and begin to burnout - so I loose if not release accelerator's pedal. And of course - winter driving - we have lot of snow and sometimes FWD LSD cars have really more practicability than non-LSD.
