The bearings are the infuriatingly uncommon 950 type and relatively speaking they are flippin expensive. I think I paid £5+ for mine as the only ones I could find were genuine Tamiya ones and you only get 2 in a pack as well.
To be honest I am not sure the "tensioners" are strictly necessary as I ran my car without them with a 5.5T b/less motor and had no problems with belt slippage. They don't actually tension the belt itself, they're just there to prevent it leaping away from the centre drive-pulley under heavy loading/unloading. I only put them on as I'd already ordered them beforehand - not realising I needed some 950 bearings too - and when the bearings finally arrived it seemed a shame to leave them in the spares box.

Thanks for that, nice one
