I attended my first 1-day HPDE at Streets of Willow last month in my '97 Civic. I was talking to a friend last weekend and he told me to get my alignment checked out because he had positive and negative camber on his S2000 after running Streets of Willow.

QUESTIONS:
1. Do HPDEs typically mess up your car's alignment?
2. Should I check get my alignment checked out after every HPDE?
3. If 1 or 2 are "No", then is Streets of Willow particularly bad for a car's alignment compared to other tracks?

Thanks!

 

No, not unless you go off the track, or hit one of those holes you typically find at the start or end of the striped curbing at apexes or trackouts.

No.

How can the Streets of Willow be bad when tracks don't mess up the alignment?

 

Streets of Willows can be hard on tires because of the surface(not the smoothest) but you run that risk on most tracks.
Mainly because your pushing your car on a track unlike normal driving on the streets.
No need to check and redo after a event unless you smack something like NSXTACY said.
