I got an RT-performance replica Nismo V1 kit fitted by Andy at Parkside Autos in Wednesbury in OCT 14 for £800.

Andy is quite well known on the forum among the Midlands lot and has worked on a few Zed's now.
He takes great pride in his work and did a cracking job on mine.

TDI north is the way to go mate, just a short hop up the M6.
Had mine done up there a couple of times and I travel up from stourbridge so just outside Wolvo, top notch service.
Best contact them by phone or through there website though.
