After some deliberating Ive decided to keep both the z3m and z4m. In terms of the z3m work is well under way, vanos done and remap, front and rear bertini strut braces, powerflex bushes all around, and koni adjustable sports shocks with h&r lowering springs. Finally a new set of Michelin Pilot Sport Cups semi slicks. Cant wait to give her a blast, and hoping she can get close to the z4m in terms of handling and performance.
