it's a preference thing. For all out performance you can get a 1 which is going to save you the weight and that obviously translates. But personally they're just too small for me. my e92 has plenty of room and with the sport pkg it is a very capable car in stock trim. It was a little pricey but I smile every morn when i push the start button. Next month i'll have the bmw areo front add on and the M6 red lines on the car, staggered of course.
