I'm brand new to modding cars. I did many hours of research but I usually run into posts that provide me with incomplete or misinformation and go off topic. Most threads just talk about power and not reliability. I just moved and have nobody to advise me with my new hobby, so I turned here. I don't want to go stock or less aggressive. I'm trying to get more power while minimizing the risk to my daily driver. You've been a great help btw.

You can see I'm in definite need of more power in my video. The Hankook Ventus V12 evo tires you personally recommended hook up real good. Now I need to adjust my power to the wheel spin threshold and I'm done modding. -------->
