Back End Light? Options

[o0black0o]

Wondering If it just me or not. Anyway, Lets say have to stop really quick and turn at the same time. I think my back jumps up in the air then falls back down, at least it feels like it? I got my spare back there so...

Which comic book did you get all that info from?

It's all down to weight transfer. This is why the rear end of a car can get 'light' and unstable, especially when braking really hard. Brake bias puts most of the braking force to the front where most of the work is done. But front and rear braking happens at the same time. The front does not start braking first followed by the rear
You will always get weight transfer when braking - it's a simple rule of physics. The degree to which it happens is dependent on speed. This is why rear engined cars can easily 'swap ends' when braking heavily as most of the weight is at the rear. Brake bias is also set up so that most of the braking can be at the rear where the weight is.
Other factors need rto be taken into account - especially the road surface. If the surface is uneven when braking hard, it can easily unsettle the rear end of the car even more, causing it to lift up more than it usually would.
Answer is twofold. Get your suspension sorted (shocks AND bushes) and don't drive like a tw@t where you get intoi a situation on a public road where you're likely to get the rear end light.
