Steering Wheel Vibration At Circa 90km/h

[BXAFTW]

ok, so when i get up to 90km/h the steering wheel begins to vibrate/shake, in an up and down motion.

as i hit 100km/h it gets worse, i wouldnt call it violent but enough to be annoing, it tends to taper off past 115km/h.

guy i bought the car from said it had recently had an wheel alignment and i dont have reason to doubt him as the front tyres are new.

its got hks coilovers, lowered, but not overly, visually i cant spot any real camber or toe, looks pretty neutral.

what could be causing the vibrations?

cheers

Vibrations generally are the result of imbalances in the wheels. Sometimes they can come from worn wheel bearings. Have those 2 areas checked out.

you need a wheel balance $20

+ 1 for the wheel balance. Mine is doing the same thing at the moment, just gotta make time to go to local tyre place.
