Eiback pro kit vibration above 70

[11thgensiguy]

Anybody have the Eibach pro kit for the 11th gen with this issue?

I am getting vibration when going above 70 mph and the tpms light came on but tire pressure is good. Leads me to believe there is some sort of wheel speed issue after lowering.

Car has not been aligned yet.

Its on some work emotions 18x9.5 +38 245/40

putting springs on alone would not cause a vibration. Have you driven with the wheels on already?

What's up with that picture? It could just be the weird angle giving it a fish eye effect but it looks like the camber on your rear wheel is way out of whack. Is the wheel bolted on all the way???

I'm not familiar with the Si, but not having an alignment could easily contribute to vibration. If the toe is out significantly it could lead to all sorts of weirdness- oh and you probably are destroying your tires too.

Something ain't right, in any case but it's hard to tell from pictures (especially that one) and zero context other than "springs installed".

No the wheels came off a wrx too so ima try a balance and alignment just making sure I didnt miss anything I might ve forgot. I wouldnt think id need camber arms or adjustable end links and what not for a 1 inch drop

ask a shop to balance the tires - tell them you have a vibration so they will check to see if you have a bent wheel or bad tire

edit: sorry didnt see you had that in there.

Lowering springs would not cause a vibration but may amplify a vibration that was already there beforehand.

Did you have those wheels and tires on before the spring install? If you didn't or if you did and swapped the front to rear, then yes most likely the tpms light will come on. These cars don't measure tire pressure, they measure wheel speed. Tpms will go off if one of the tires has worn more than the others and then moved to a different position. Should do tpms reset every rotation.

Alignments don't fix vibrations. You need the tires balanced and checked for irregularities (flat spots, bubbles, missing chunks, some road debris stuck to tread, bent rim.)
