I was wondering if it is possible to, ahem, "modify" the seat height adjuster to make the seat drop down any further, i have a mk2 ph3 2005 1.2. At the moment I feel like I am sat on the car rather than in it if you know what I mean? Also I am getting a knock from the rear-it sounds like a ball joint type of knock that you would expect from the front-gonna check wheel bolts in the morning, any other ideas chaps?
