I had to LOL at this because I have had a panhard rod snap on me and rear axle out of line was an understatement, I was looking in my rear view mirror and the whole rear of the car was swaying from side to side and one second you could see 3" of the tyre sticking out and then then it would go back the other way and was impossible to drive over 15mph. But anyway my 1st Starlet was dropped 60mm'ish on coils and strut braces thats it. Most my mates own 106's which are renowned (sp) for their handling and they cant believe how well that car handled, they have all been in my car at speeds of 1##mph through a set of bends and I say to them I am not going to lift and I dont, they wouldnt even try it in their cars which are known to handle!! So yea I wouldnt say its needed but down to preference. The GT has a cusco one fitted but if it wasnt on there I doubt very much I would go and buy one. Just my 2p
