I see it's an 05'. Have you replaced the front control arms yet? Check the rear bushing carefully.My car has been shaking for a little while. It's not like an earth quake but it kind of vibrates. It got better with my hub centering rings but it's still there. It happens mostly when braking. I did install coilovers but it shakes prior to that.
It really depends on how bad the bend is. Take it to a tire shop and see if they can balance it....if not, look for a new rim.I was on stock suspension before the coilovers.. And I have not replaced the control arm bushings. I have Toyo proxy 5 tires that have a decent amount of tread left on them. I do have a bent rim but I feel like it is also something to do with the suspension.. Because I did not have any shaking with my winter rims. So say it is a bent rim, would a balance fix that?
If they can't balance it, you don't have to buy a new rim - there are plenty of shops out there that specialize in removing bends from rims. I bought a set of rims for my A4 which turned out to have 2 bent rims, and a local shop fixed them right up for a lot less than 2 new rims! Just my $.02It really depends on how bad the bend is.
