Having finally ditched the runflat tyres(after 2 and a half yrs of owning myz4),i wish i had done it ages ago.
The ride is far better,with no tram lining,or crashing over bumps etc.
Couple this with the bmw strutbrace i fitted a few weeks ago,and the car is tansformed. it now feels more like what the car should have been out the box,so to speak.
I can now safely say its now the equal to the porsche boxster 2.7 my mate used to own(which i drove a few times),but faster. previuosly,the z4 was worse due to the comfort/handling not being as good/tho now its superb. turn in is better,sharper and the comfort is vastly better,while staying fully flat and planted thru corners at speed. awesome!!
