Thanks for that, the reviews iv,e picked up on the web seem to be very mixed but not heard from anybody on here that they have used them and they've fallen apart so might take a punt on them. Just can't get my head round how they can sell a pair for £70, presume there made in china.
If I remember correctly the standard Focus shafts are hollow and in a Rocket you are moving much less weight. I used the Honda engine and the shafts were solid, so I had some custom made at a cost of £180 a pair by the engineer who makes them for the Spire race cars and they were solid. J&R quoted me £500 to custom make the same shafts? I politely declined . £70 sounds very cheap.
