Question guys and gals. I put on new brakes and did the lift around the same time. I still have so much shaking up front when braking. Do you think it has to do with needing an alignment?
Yah i got a super 40 si/do. I even got an exhaust video on youtube i just got to find it. I dont have a tach, but i think about 2500 was about as high as i rev'ed it. 97 f150 4.2L flowmaster super 40 out to duels - YouTube
