E89 35i suspension setup
I am wanting to improve front end grip and turn in on my 2009 car. I have already fitted Goodyear non run flat tyres.
What things are adjustable apart from toe in/out? What setting would you reccomend |

switch out whatever goodyear tire you are using for an actual performance tire, like Dunlop ZII, Bridgestone RE11, BFG rival etc as step 1. Weren't you prioritizing all season / wet when you were shopping? No surprise there is a lack of grip with that type of tire
I'd try zero toe and maximum possible negative camber You might want to bring the rear toe closer to zero and slightly less then rear negative camber to something like -1.6 to help the rear rotate a bit more and reduce the understeer feeling good luck! |

RE the tyres, I am based in the uk, we get a lot of rain
The tyres I have just bought are actually very good and a very popular choice in the uk for performance cars = http://www.tyrereviews.co.uk/Tyre/Go...ymmetric-2.htm vs http://www.tyrereviews.co.uk/Tyre/Br...tenza-RE11.htm They are also a great improvement over the run flats, so that bits sorted So, are you saying you can adjust the camber on a stock Z4? |

He is asking for grip, and asking for alignment settings, which suggests he is very serious about finding said grip. Tire is always the place to start, and looking for the street tire class winners (the examples I gave were such tires in years past, the goodyear is not) is a good shortcut to finding grip Sorry if that came off as harsh, but I really don't think Goodyear makes credible "actual performance tires" in the way I think the micheline PSS on my M3 are not. I used 40% of tread in 1 DE, and they started to melt. unacceptable. Yes, you can adjust camber on E89. There's not much available though without going to camber plates. Mine had -1 front and -2 rear, and toe i think was 0 in front and slight toe in in the rear |

well in the UK those tyres are well regarded and provide similar grip to the Michelin you mentioned however the wet grip is better. If I was not concerned about wet weather grip I would run track day tyres which are even grippier
Probable best just to agree to differ Thanks for the info on camber |

Agree on the tires, camber and toe adjustments. Next step could be upgrading the rear sway bar, but I have no personal experience with this. I prefer the "going in slowly and exiting sideways"-approach to life. Thats also why didnt get something mid engined...

The asymmetrics gy are far better than the mich pss imo. You are welcome to check in the link below my sig, you can have the alignment settings I got from a racing company in germany for 50 euros, I wish I had them earlier before paying 4 times for alignment experiments.
