Have same type info need before buying wheels and tires
Hi All,
New to Z4 world. Need some wheel/tire advice.
Just purchased a 2007 Z4 Coupe 3.0si with steptronic with 8 K miles – mint condition. The non M Z4 with steptronic choice is due to a number of complicated reasons. I am a HPDE Instructor with PCA and BMWCCA. Had a dedicated track car. Now need some new Z4 (non M) owner advice in two categories.
Q #1 - What more aggressive wider 18" wheel and tire sizes will fit my non M Z4? Know the non Z4 wheel wells seem to be smaller? I ran CCW Classics 255F and 275R RA's for the track only on my track car. What wider wheel sizes and tires can I run on a non M Z4?? (have 18" x 8 wheels 225F and 18x8.5 255R original run flats). Z4 Suggestions I have gotten is the Hankook Venus V12 Evo for street and occasional DE's? Maybe run 235/40 F on 18” on 8.5 APEX EC-7 F, and 265/35 Apex EC-7's R. What yee think?
Q #2 – How does the non M Z4 with steptronic paddle shifter work for HPDE days on the track?? What modifications would be wise for occasional DE use? Most of the time I am in the student's car so will not do a lot of track hours. If I can get better wheel tire package, do I need to add SS brake lines, more aggressive brake pads?, higher temp brake fluid? Other minor changes that would help for occasional DE use?
I would appreciate some opinions.
Tom
