Arai will do a complete fitting service for you if you arrange it through their dealers.I just couldn't get my Rx7-rr to fit properley(US version,Kocinski),different shell,so they came to my local Hein Gericke and spent two hours with loads of different pads etc and literally made me a made to measure lining/padding set.Awesome service!An airduct cracked as well,sent it to them and they changed it FOC.
