чуть ниже висит тема, сравнение м3 гт2, и м3 гт4.

гт2 выглядит так же как гтр, вес заявленный на 100кг больше, мощность +15л.с

это все таки одна машина или разные?

Я точно знаю, что для американских и европейских гонок омологированы два немного отличающихся M3 GT2, в частности разная конструкция задней подвески (европейцам не понравилось, что на прототипе стоит принципиально отличающаяся от стоковой М3 подвеска) и разный минимальный вес.
Судя по фото могу предположить, что здесь приведены данные для М3 GT2, выступающих в американской серии ALMS.

П.С.: Алексей, по-хорошему надо бы указывать ссылки, когда что-либо копипастишь, а то иногда не понятно откуда ноги растут

Это оригинальный BMW M3 GT2 построенный для американской серии Ле Ман.
