That's why those with 19's on the car fit 19's to the trailer. :D
Nope, no engineering required for small trailers. They're designed at the discretion of the fabricator/builder. Whilst following general guidelines, as dictated in the document on "building small trailers". The minimum requirements are insanely easy to meet...
PM me if you want alloys on your trailer that match the car Baz ;) :D
