ESS 525 Z4M after full power flex bushing conversion and going with square tires
Just tested out the Z4M after replacing all the key stock bushings(RCAB, RCAB rear upper outer) with power flex( I previously had the turner shim RTAB). Wow the car feels so much more responsive on turn in and the rear communicates much better as well as being more consistent. Also decided to try out running a square tire setup on my staggered wheels because A its cheaper and B the 285 sport cup 2's i normally run are perpetually out of stock. To say she liked the changes is an understatement , went from a 1:19.6 to a 1:18.1 at Roebling Road .

I have been looking at Powerflex for years now and still haven't pulled the trigger on a full set.
Thanks for the review and cool pictures, it's much appreciated. |

Thanks ! It def allowed me to finally take full advantage of a very good MCS suspension set up . Pulled lateral 1.34 G's in turn 1 on that 1:18.1 lap . Trofeo R's are a damn good tire as well .

So what tire size are you running? From what I've read, people generally recommend square sizing on E46 M3 but not on the Zed, that's why I just moved from 225/255 to 245/265.
And yes, it looks more like a track car. Can't imagine powerflex would be very enjoyable on the street? Even with my completely stock Z4M I can't say the ride is quite pleasant....depends on the roads I guess. |

Do you use THIS suspension? Never heard of them before, but I'm impressed car is still not a pain in the ass to drive on the street. Which variant of the Z4M package did you get or is this a custom build? What about springs? How do you like the ESS 525? (I'm also considering one) Sorry for the 500 questions. |

LOL ! That was funny...should've just let you pass him for less humiliation.
So the Trofeos are better than Cup? Have you tried Yokohama AD08R? I wonder how good they are since I'm on Super Sports now and can't say I'm really enchanted by their performance, keeping in mind that they are more of a street tire, but still. And how do these fare in the rain on normal roads for example? |

That 911 seemed pretty twitchy on some of those turns. Good runs though
How did you find down force with the diffuser? Make a noticeable difference?
