I run Sean B's old R+D box.

-Sean had a failure with 5th gear, were the weld broke, (bad batch)
then he chewed 2nd gear, which could of been a notchy gear change previous.

-Martin H, only knocked a dog off once from road driving,

-I've chewed 2nd gear once, due to gear change, where i put the power on slightly to early. But car done 6k road, track and sprint miles.
i rebuilt it, but cost £1100 in parts.



I think the main issue is, when R+D 1st brought the box out, it was NOT developed fully, and Roger used his paying customers as the development, and charge them each time it failed.
as well as R+D hasn't got the best customer service.
