Hey guys. After a long an quiet winter and the last month full of electrical gremlins my car finally started one week ago.

After replacing opti, coil, wires, plugs, ICM, alternator and starter, then pulling them all out and re-doing the installation it finally started and sounded pretty good.

I changed the oil and took it to the track Saturday. Ended up winning my class but the car was shaking at the big end of the track.

My car has never had a very high mph and I was trapping about 109 which was normal for the weather conditions but the shaking bothered me.

The shake seems to come from the front end of the car and only kicks in around the 1000 foot mark. Everything else is smooth. It feels like the front end fascia is buckling (but I am not going fast enough), or there is a shirt hanging outside the passenger side door flapping around.

Any ideas as to where to look? Nothing seems loose or questionable when the car is sitting still.

 

Did you already check tire balance and driveshaft ?

 

what about the front air dam?Or any other number of plastic things in the front of the car?Any loose bolts,its prolly jus some little plastic thing giving u trouble...

 

Are your air deflectors, ( Left and Right side), in place.... Some people make the mistake and remove the left side to allow more air flow to the air filter, but it also creates turbulance.....
