Don't cut your ARB out, what a crazy suggestion.....
It depends entirely on the golf from which they came, which end you're refering to, and what make the coilovers are.
Any mk4 golf coilovers from a FWD golf will fit a cupra.
MANY fwd golf coilovers are made with the tabs for the LCR drop links included. Any of these will also fit an LCR.
Cheap ebay coilovers for the mk golf don't have the ARB tabs, so can't be used on an LCR, but can on a cupra.
It's all about the tabs on the struts. If they're fitted, you can use them on anything. without the tabs, the LCR is out
