I went to my first autocross this past weekend and when i exited from a rather large radius corner my front wheel were shuddering terribly. Dont remember if i was on the gas and turning at the same time but Im suspecting something with front suspension? Maybe tension arms? Any ideas? Thanks.

Car is lowered on sportline with stock struts i think.upgrades rear sway. strut bars front and back. Nothing else. stock motor.

this may be a stupid reply to your question, but try tightening your lug nugs to spec.....

ill try the lug nut thing. Im pretty sure they're on properly.

i had 9 runs on the course. it was was corner on a gradient. when i was exiting it was an upward gradient. and if i remember correctly, it happened 7/9 times.

i am not referring to the rear sway bar, and the kig pin is what holds the hub on the car

a friend of mine as said it could be a ball joint.

anyways, i wouldnt even drive the car down the street without getting a experienced machinic to look at it.

I hope you understand that me and every1 else cannot fix this problem for you over the internet.

sorry bud

its gonna be hard to answer this question, but here's what might cause it....warp rotors? bad tire wear? alignment is bad? tie rod ends? lower ball joint? these happened to me, but there might be other reason. gl finding what it is
