just been thinking, something I dont do a lot of. I've just had a rarb fitted and eibach pro kit fitted, which I believe drops the vrs by about 20mm. should I change the drop links as they were obviously were designed with the original ride height in mind if so what make can people recommend?

No, you will e fine

^ This. Shortened drop links if you're going really low.

Just dropped mine on coilovers and wound them right down and I fitted shortened drop links and il be honest I may fit standard drop links as shortened ones seem too short even on there longest adjustment
