My Z4 (3.0si) has always been quite a tramliney car since I bought it roughly a year ago. It's been modified by previous owners, different wheels (I'd say they fill the arches more so probably have more offset, and the rears are now staggered/wider from 235 to 265, keeping the same rolling radius) and eibach lowering springs, and undoubtedly it's going to be effected by those things, as nice as they look: I've done a few things so far, all have improved it but I'm not quite happy with it yet and want to do more. Here's what I've done - Reduced tyre pressure (from 36 to 31psi) - quite a big effect overall, going lower doesn't have much effect - Changed rear trailing arm bushes to powerflex - made the back end feel quite a bit less wandery - Changed rear tyres (to eagle f1 asymetric 3 from toyo t1s) - didn't have much effect but I needed new tyres anyway - Got the alignment done at a local place - Everything is in spec now, apart from front camber which can't reach spec due to the lowering springs Things are better, particularly at the rear, it felt unsafe on motorway before, it's stable enough now but does still get pulled about (tugging through the wheel) quite a lot more than my previous car (S2000), I'd like to improve it further. Things I'm thinking about doing: - Replace front-end bushes with powerflex - Replace suspension with BC racing or KW coilovers: Then I could adjust the right height up a fraction, not as height as stock but maybe 10mm up to get a bit more travel and maybe allow the front camber to get more in spec - Replace front tyres - Get WIM to customize the geometry to try and improve things I'd like some thoughts on the above, what I should prioritize doing, anything I'm not thinking of?
