Ford Zetec ST170/RX8 adapter This adapter plate was designed to bolt a Ford Zetec engine to an rx8 gearbox utilizing a normal ford zetec flywheel and clutch off a 1.8l/2.0l zetec engine flywheel not the original ST170 items. You will need to use a LRS707 starter motor and use a rwd sump unless you want to grind away material off the zetec fwd sump it is a bit of work using the standard fwd sump but it is possible for the person on a budget. In most cases it is possible to use the rx8 clutch arm slave cylinder and release bearing with very little work, but In some cases the clutch arm pivot point height might need ajusting to suit. Tested on road and in motorsport to ensure we offer the most reliable adapter plate on the market. Adapter plates are normally in stock and are sent out next working day via a 48hour courier. If the item is out of stock there my be delays but we try our best to inform the customer as soon as we can if that is the case.
