When I accelerate hard, the front end of my car shakes. All I have done is Bc Racing Coilovers and exhaust. What would cause this problem?

possible alignment or wheel balancing?

Did it start after you changed something? Check your engine mounts.

I got a wheel alignment and wheels balanced. when I got my snow tires, it was shaking, so I went back and got them rebalanced, it was still doing it. But I'm still having a feeling it's that. My motor mounts look fine.

Make sure your lugs are tightened properly. Go in the star pattern. Also check the strut bolt is tight under the hood.

maybe the tires themselves.

if it's happening only under hard acceleration not when cruising at speed, I would also suspect an engine tuning issue; like bad spark plug/ignition coil, a clogged fuel injector, or dirty air filter. When the engine is missing something for combustion, it will start shaking and under hard acceleration you'll need to deliver a lot of fuel/air/spark into the engine suddenly

Ok I'll go check the lug nuts and strut bolts. I have a velocity stock on with screen door mesh for filtering lol

It can also be the bearings too. I had to replace mine at 120k
