Ian,
OMG that is pure automotive art AND RHD too ! What have you done about the steering rack, as the M3 is on a quick rack, but the RHD 325 one is pretty slow by comparison?

Franco,
That one is the ST8130P and is £1287 (£1,087 for the Stack and £200 to fit it in the binacle with idiot lights, complete with loom so that it plugs straight into the OE Ford set up. Also if you have two 52mm gauges, these can be fitted either side for no additional cost).

The ST8130 (which has all the same features as the P version, except fuel pressure), is £117.50 cheaper.
