Good Day Everyone

New to the site and had a question in regards to flat track. Im looking for info and all resources for ordering. Im located in Canada close to the Niagara Falls Border and ride 2009 CanAm 450ds.

Wondering what I need to get set up and where to get somethings. CanAm is a pain for parts but should be able to manage.

Tires/rims = size?
Lowering Kit = ?
Wheel Spacers = ?
Hot Cam or Bore kit = ?
Sway Bar = ?
Etc.

Thanks everyone.
