Because a garage will always try to sell, sell, sell. It may be worth getting it checked (For free) and IF needing adjustment, get it done.

The Lo springs are TUV approved so meet all neccessary regulations, they just aren't a big name like Eibach. Can't see a problem with them, also get free next day delivery AND 12 months warrenty. Not bad for £75.

The axle spacers are easy. If you wait a few more days Ill be doing a guide as I'm fitting mine tomorrow and there will be a detailed guide, with pictures along the way.
