I had my first Autocross with the Z4M this past weekend. I have autoX'ed several Mustangs and an ST
i, so this was not my first dance.
Prior to my First Outing I added the RTAB limiter kit, Camber Bolt & washer kit, pulled the alignment pin and added the BMW Strut tower brace. I Had the car realigned to -2.5 front and -1.9 rear, zero toe up front and 1/16 in the rear. I also acquired an offset set of Apex Arc 8's to loose 6 lbs per corner and clad the rims with some Extreme Summer Rubber (RE-11's) 235 front 265 rear. everything else is stock.
I had an amazing experience, the car handled like a Champ!. I went into hard corners hot and never had a bit of under steer. This car was built to run hard!!
