Default Issues after spring install.

I am not sure if I am just being really really picky and it's simply the car is going to ride with springs and 18" wheels/tires, or if it's actually something worth looking into.

I noticed last night that the feeling is coming from the left driver side of the car. It feel like an extremely out of round tire or even bent rim or something. I can really feel it at around 40-30 mph when I let off the gas it gets more pronounced.

It's kind of hard to describe...but it's definitely something I feel worth looking into....could it be a blown shock? Or this is a long shot, but what about the wheel lug nuts being over-tightened? I believe I torqued them all to 100. Is that about right?

Any thoughts help here guys. I am certain we torqued everything down. I seriously remember torquing everything down after the install. Could it be a spring out of it's perch maybe?

Just may be a long shot, but check your tire pressure in that tire. The day after I bought my car, I had the same problem. My tire was flat but couldn't tell because the sidewall ws so short. It had run flat tires on it and didn't look flat. When I checked the pressure, there was zero lbs.

Hmm, I will check that out. I feel like there is no possible way anything in the suspension could do this. I guess I will check the lug nuts again as well, maybe one is loose or something. But it most definitely feels like either a weight flew off, a tire is of balance, or the rim is bent. It's making me upset. I can feel it at all speeds.

Is it more pronounced during braking? I understand all speeds. Did you check your bushings? 100lbs is fine for your lugs.

I have an alignment tomorrow at LS at 1pm. Sheit, I have to figure out if my dad can take it cuz I am definitely playing golf tomorrow!

Me and a couple buddies checked the lugs and they were fine. I also checked the tire pressure and they were all around 38 lbs. I am almost certain we torqued everything. I don't want to pay another 50 bucks to get them balanced; thats a load of garbage. They should have came correct from OEWHeels. You think if I complained OE would pay for my balance? Or reimburse me I guess.
