Good afternoon,
I would just like to say thank you to everyone who has replied to my topic, the replies have been most helpful. I will let you know how I get on now the restrictions are being lifted. Just as and aside, I found out today from an obscure Lexus paper that the springs on the F-sport are 10mm shorter than on the other IS250 models, which may be one of the reasons for the suspension on the F-sport being firmer. Anyway I thought this may be of interest those of you who understand these things far better than I ever will. 🙂
