I have bought an 08 STi hatchback which has had the original suspension bushes replaced with the Nylon type. The resulting ride is great on smooth tarmac but terrible on country roads, over cats eyes, drain covers etc. It has made the car very noisy and uncomfortable and everything seems to rattle. Has anyone had the conversion done so that the two bush types have been compared? I want to know if it is worth returning the bushes to standard spec for a more comfortable ride. Thanks.
