I was looking into the Stage 3 kit for my 2000 s4 and i was wondering if anyone could give me some help deciding on which one to choose. I'm still going to be using this car for an everyday driver but i want to take it to the track during the weekends. I'm looking at APR's and i'm pleased with their products i have on my car now but I was hoping for any feedback on any of the bigger turbo kits would be greatly appreciated.
