apart from the obvious difference, what is the difference between 140 and 150 mph clocks?? can u just put the lockwood white dials 150 on 140 clocks without any probs, got none here to compare at mo

[Sauna]

they'll fit but I don't think the numbers'll line up properly

if you do this it would put your speedo out by about 5 mph, your better off getting the clocks from a frst and putting white dials on them

But by fitting larger wheels, you actually fix the inaccuracy. Put the other way, 150mph dials on 140mph clocks give better accuracy on Fiestas with 17s - it brings the margin of error from around 5% to something more like 1%.

ooooooooooooooh, thats well handy to know

what about 18"s?

[FezzR]

or if u aint got big wheels just change the speedo mechanism attached to the rear of dials

I thought RST dials were up to 150mph anyhow?

[Mav Singh]

can a factory standard RST do 150mph?

[Stoned]

No but that does not stop Ford putting higher clocks anyhow. Common practise.

My 1.6s can only do 110mph but Ford still have a clock that goes up to 140mph.
