As team drivers we test all the options & take on board all that is said on the forum. All new parts are vigorously tested to see what is going to work best in performance & durability.
DJ im not sure on the age of your kit but from late 2008 a running change meant 808 kits came out with
V2 gearbox cases which had a tighter tolerance on the bearing bore, it was also deaper to give more support.
Blue shielded bearings had an improved shield which retained its form.
Aluminium bearing spacer
Metal shielded bearing .
The 808 is a race car & will require maintenance but for that you will be rewarded with the best car on the market for reliability. I would strongly suggest building the car as std with the latest parts. I personnaly check my bearings on the pinion gear every 3 meetings which equates to 3 hours running, I check for wobble in the front bearings ( double blue shield) as these are what take the load. All i do is hold the centre race in my fingers & twist the outer to check for excess side play, its obvious if its worn & will just replace saves for heart ache at the track. The metal shielded last an age now & as long as i can feel friction in them from the grease they are fine.
The other simple check between events is to move the drive shafts to see if side play is developing in the bearings again this is obvious if the bearing is on its way out.
Other than shimming your diff right & avoid nose planting the up ramps you should get hours of trouble free racing.
