Ive got them on mine, and whilst they need adjusting (back it a touch high, front a touch low(for commuting)) they are fairly impressive. Over multiple small bumps you can get a bit of bobbing (no more than other coilovers though).
Next trackday is Feb 21st, so thats when they will be used in vain and wound right down.
The car certainly puts the power down alot better now, and im actually quite pleased. The ride is pretty much the same as the standard cupra, albeit a lot lower in stance.
You dont get the spanners with the kit to adjust it however. So you will need to add that into the price if you want to do it yourself. AMD are getting me a price for these when the AP factory reopens.
