First thing I thought of when googling M3 power bulge was that the car looked like it was rocking a half chub
. I'm not trying to see vents honestly.
I'm really in the same boat as yourself. Debated the SC set up, even Stillen, but it comes down to cost to get this car where I want it vs buying a new car outright. Plus, mine sits at 37K miles and is my DD. By the time I'm able to do this, it would be next year sometime. By that point, I'm at 50K miles. Do I really want to boost a 50K mile DD? One part of me says, and?...why not?. The other says to do simple mods, save up and get something fresh. It's a struggle.
