I had them on my
mk4 ibiza and for the money i thought they were great! a tad bouncy at the front, but i think that's cos the kit has helper springs on the front shox too.
They handled really well, and were the most comfortable coilys i've ever felt...from my experience, they are the happy medium between rock hard with amazing handling, and comfortable with dramatically improved handling.
How much they offering them for? I'd prob say go for it!
