fairly easy to fit heres a guide:

1. drop whole subframe. (a must as you wnt remove the other bolts without tearing apart the bushes)
2. burn out old rubber thats being replaced
3. clean up the bush shell and pin and chamfer the pin ends
4. grease up bush and install in arm (correct way round, comes with instructions)
5. grease up pin and install into bush. can require a LOT of effort which is why you need to chamfer the pin ends a fair bit.
6. refit subframe, exhaust hanger, hand brake cable and rear brake lines.
7. bleed brakes
8 done

subframe realigns perfectly with no hassle
