I got an mx5 a few weeks ago and have noticed the steering is ridiculously light at around 65-70, to the point of feeling un-safe. I have heard a common cause for this is the suspension geometry being out of wack. Can anyone recommend a place in south London that will do a good job of setting the car up and not cost the earth? I am in the Blackheath/Greenwich area, so a decent place around there would be great. Cheers!
