Also, if you wish to retain the seat adjustment (up / down / forwards / backwards etc), then you also need the side mount to Ford base adapters as well, which are around another £70ish.
If you definitely want a Recaro, pick the seat model you want, the mounting type (fixed with just side mounts or adjustable with Ford base adapter) and I will give you a price, as I deal with Recaro direct
