I only had time to try the newly bought Z4 yesterday around COTA, but today I'm continuing my tour around the comboes. I see that Star Mazda got an update for the tires, which was just about time. I guess that will boost the participation back to where it was years ago, might make it my main series to begin with. Originally I was planning for a RUF Cup full-out attendance, now I also have to check that car out though as it got changed. I simply don't like COTA, but I expected that from the very beginning. All of the turns have like 9 ideal lines and impossible steering angles, blind braking points. It's just not my style of motorsports racing. It's just too American for me, but that's a problem for me and not the developers. The track is well-done, the graphics are nice and the details look fantastic. That's a great job on both the car and the track.
Btw, don't even try to compare RUF Track and Z4 in driving experience, they aren't even remotely related, other than being in the same series.
