Sorry, boring question.....but does any one know what boost pressure a Prodrive'd 98MY WR creats, as I have ordered a 0-15psi guage-is it OK? I am also fitting an oil temp. guage next to this one in the ash tray hole by the *** lighter, but do not know where the sender on the engine is for both oil temp. or boost. Reason for this is, the only guage that matches the car's existing night illumination (red pointer/green numbers) is VDO 'Vision' guages fron USA, and that's all they do. Has anyone done this and have any ideas before I screw it up?

Also, will putting ZX1 Extralube in the gearbox oil upset the viscous diff.? I've heard that this is a good way of freeing up the ridiculously stiff gearchange on the so-called 'quickshift' box.

Also, will putting 215/45 or 40 ZR17 tyres on instead of the 205/45 17 P zero's that are on the car now give a smoother ride(by increasing the tyre wall height)?

Appreciate any knowledge! Thanks.
