So, i have own this 96 gsr for about 3 months now and today is my first time hitting vtec on the highway. While shifting and keeping in the powerband i noticed only in 5th gear my steering wheel start to rapidly shack, but stops as soon as i take the foot off the gas. The wheel aliment has been done 3 months back because i had to safty the car. As of right now i have winter rubber on. I don't know if the tires might have caused the rapid shacking bacause of being on straight pavment instead of ice or snow? I would change the tires out today but it started to snow again. it been almost 8 months of this ****.

Any thoughts on the matter? thx

 

Im guessing at 60+mph? Wheel balance on the fronts.
