Used M4 Concerns
Hello everyone,
Considering how inexpensive the earlier generation DCT M4/M3s have become, i'm sold on purchasing one. I've always done bolt ons/tunes to my cars (E92 N54, F32 N55) and enjoyed the life out of em! however, I've got a few concerns regarding the S55 after reading countless forum posts:
1. Is it safe to buy a used, out of warranty, stock or already tuned M4/M3? Will it hold up in reliability?
2. Does the GTS transmission flash reduce or worsen the probability of spinning the crank hub?
3. Considering the 2015/2016s are out of warranty, should I purchase an extended warranty even if I wish to tune it?
4. Should I stick to a 2015/12+ build because of the new bedplate implementation?
Best regards
