 Where? Innovative chassiworks in Layfayette MN...

Sponsered by who? Innovative chassis works

How much ? $ 170 for two day seminar

Prior requirements? you are alive and are interested in drag race chassis setup.

 Lafayette?  I didn't know there was anything in that town. I deliver pop there about once a month. I think the population is about two. Whoever goes won't have any problem finding the place.

 Sounds pretty indepth. Way more info then I would ever use.

I went to the one at Competition engines in Eagan a few years ago..
Its drag race oriented.. a lot of the chassis setup talk is geared toward adjustable suspensions, four links, etc.. But the basic knowledge is killer.. Not sure if Im going...But have friend who is interested so you never know. dont go to this seminar hungry or tired.. its hardcore.
