Can I buy the parts individually?
Yes. Each Group B part is also listed on its own, so you can build the package in stages.
How much weight does it save?
Mugen quotes approx. 38kg across the full set of parts compared with the standard car.
Do the fenders need painting?
Mugen recommends painting the fenders in body colour, leaving the ducts in carbon.
