"Car jumping from the rear"???
Meaning that you loose tracktion?

The RF tyres are too hard, not helping the suspension.

The RF tyres weigh so much, that the unsuspended weight for the suspension is too much.

Also really low profile tyres do no help the soft suspension.

The standard shock absurbers (and springs) are a compromize between comfort and handling!

Solution:

Get 225/50 17" tyres with the standard suspension.

With 18" - 19" low profile wheels get harder rear shocks (and springs).

Get rid of the RF's.
