Have the garage fitted the wrong shocks and springs

[BillyCool]

Seeking help from the collective big brains on here.

2014 Leon ST FR 2.0 tdi 184 151,000 miles.

Broke a front spring last week and it sent it in for a new pair. Also asked them to fit new shocks since they had never been changed and the labour isn't much different to just doing the springs.

Got the car back and.....

1. Ride height "seems" a bit higher at the front. Might be me but just looks like more tyre to wheelarch clearance. I think the ST FR 184 is 15mm lowered from factory?
2. Front end cornering - my big issue. The car drives fine in a straight line. I have lots of country lanes where I am and I know how the car corners and it is very composed on the road, nice responsive steering and basically corners like it is on rails. Now, it sort of "wallows" and front end sags/dips/understeers. Not the positive steering I'm used to. It's like driving the wife's Volvo, with it's "normal" suspension. It just doesn't feel right ad there seems to be excessive body roll.

Parts fitted:

KYB RA1312 coil springs

NK 65473890 shock absorbers

Now - both parts are "compatible" with my car according to autodoc and other places. However - if the car is 15mm lowered, these springs can't be suitable for all models as autodoc suggests?

The car just doesn't feel as planted on the road and it just sort of wallows a bit on the corners - you can feel the front end dipping. I'm hoping you know what I mean. I'm wondering if I need lower and/or stiffer springs and could/should I have other shocks?

Anyway - it doesn't feel right and it's like it's a different car.

So - the questions is, is it just me or should it have something different fitted? The pic is of it after the new front shocks/springs were fitted,.

Appreciate any thoughts.

One thing that I now do at service time is to measure and record the ride heights front and rear - both sides, I do that after making sure that the tyre pressures are correct - really just to avoid getting into this situation "is it me or is it sitting higher/lower than it used to?" , also probably helps with detecting when/if a short end of spring has broken off - or any other suspension issue/changes have happened and gone unnoticed.

Maybe that sounds like overkill - but if/when you end up in the situation that the OP is in, you'll consider that it is time well spent at service time.

Edit:- look at the bottom of that Autdoc link and click on OE Number - that is what you now need to check, ie is that what SEAT fitted to your car at the factory.
