axle swap time how capable is a std crownwheel and pinion

Hi,

I´m about to major upgrade my drivetrain.

After cosidering a lot of options how to strenghten up my rear axle, I found this to be the cheapest and easiest solution.

All those axle swaps dont really work out and are nowhere as cheap as this. Even H100 or Estima Axles which cost about 100€ with brakes and everything from the scrapyard need so much work, like redrilling the pcd, wateryetcut the brackets, new Seals/ bearings, freshen up the brakes, change the propend rebalance it, find a decent final drive ratio etc so even to me, who can do most of it myself, or know the people that can do stuff for meis myself it not worth it.
Decent Atlas Axles are well expensive too ond they only come with a single row wheelbearing...

Anyone here using these shafts?
What I´m really intrested in, it looks to me like this kit maintains the orignal 6,7" final drive gearkit, so I´m a bit worried.
Weir says capable up to 300hp I belive the shafts are, but what about the gearset?
Anyone got real life expirence when they break?
I´ll be running nothing crazy, only around 160bhp through Ford type 9 gearbox with an unsprung carbon clutch and I do like multiple 3rd gear clutchkicks at the moment (running 121bhp).

So if any one stripped a final drive let me know what you were running and what you were doing, this hopefully helps me to make up my mind

Thanks
