1. I've just got some lowering springs off of a mate for my 1990 Orion ghia. I'm concerned about arch and ground clearence as i've got 15's on it. The drop is only 30mm and i'm not planning on replacing the shocks. Has anybody done this and has it ruined their ability to get over speed humps and take passengers?

2. Also i'm having wobble as i get over 50mph - had the tracking and balancing done and this didn't solve it - i suspect its the bushes - it is also very noticable when i turn left at speed but not right - i know its vague but does anybody have any ideas?
