It has the standard 16" bbs splits. 45 profile tyres looks to have stock front springs "black and rusty, look like the 17 year old originals. My dog bone, back of the subframe and sometime the back of the sump near the drain plug skims over some of the rougher speed bumps on my estate. Earlier I was out and trying to keep up with a mondeo st, It was a straight road heading into a 60, I was going a little faster than that but nothing crazy, the road got a bit bumpy, no speed bumps just a bit uneven and bouncy, car came down hard and I swear it was like I'd ripped the sump clean off the car. surely 45 profile tyres wouldn't cause all of this? are the cupra's this bad? Because everyone is saying "I have mine lowered 30mm and it's fine"
