Update:
Summer started nice. I changed new oils (Valvoline 10W-60), installed Whiteline front roll-bar, new tires Toyo Proxies R888, Sparco Corsa seats.
I just have to say that my car is now almost perfect to hande and drive. There is enough power in the engine for me and the seats give a lot more feeling.
I also visited in race track for the first time in this summer. And hell yeah, the car is so perfect in race track also!! I drive same laptimes as stock E36 M3! My car is so fast in corners...
There is still some body roll in cornering, but its fantastic to drive! I still have to get a better rear roll-bar.
