got a full set front/rear from e bay a few weeks back and the quality was great and my rev 5 feels all the better for it. best £40 I have spent this year.
you can buy the mid sill section, but the front of the full sill comes on the piller section and the rear of the full sill comes with the rear quarter, been there and done this, fortune me lad a fortune.
can someone tell me the differences from the earlier sw20 models to the rev 5, suspension seems to be rare and expensive for this NA, car and my old rev 3 tubby was not that bad.
