TRANSMISSION

The ST250 was equipped with Ford’s Getrag MMT6 gearbox, as previously found in the six-speed Mondeo ST220 and turbocharged Noble sports cars. And although it’s not quite indestructible, it’s proven to cope with more torque than an EcoBoost can throw at it.

The ST250’s clutch isn’t quite as tough, though. Its limits are around the same level as the standard turbo, although sensible use of the loud pedal from standstill should avoid any issues. Collins Performance, for example, is yet to change a clutch because its tuning packages stop short of 300bhp.

A test drive is vital. Check for clutch slip by driving in a high gear and accelerating hard from around 2000rpm; if the road speed doesn’t increase in line with engine revs, the clutch has seen better days.

Beware of vibrations felt through the clutch pedal or any baulking when changing gear. The standard change has a positive mechanical feel, but there should be no gear selection difficulties, especially in first or reverse. Several early ST250s had their clutches and even entire gearboxes replaced under warranty, although reported problems are scarce.

If your potential purchase happens to be modified, it may come with a quick-shift kit, which shortens the throw of the gearstick - a very worthwhile upgrade. Bear in mind, though, that a modified machine has probably been driven hard, so double-check that clutch…
