What large size seats can you fit into a roadster
Most should fit really. Bimarco seats would be a good bet, they fit up to a 38" waist and are a quality item for the money.
Dont want to buy seats to find they wont fit
In fear of stating the obvious, i believe a tape measure would come in use. Then, if and when you find some seats you like, get detailed measurements of them and check they fit.
