XR's got a better tailshaft stock.
Speaking of: Got my new straight, balanced, new race-spec uni fitted XR shaft back today from the Diff Dr. Reco box arrived on my door step some time during the day. So I've got a busy weekend ahead.

Yet not one of them work for a company that produces over 400 per day for the blue oval range of cars!!! No one even takes into account the info i give them yet they still know all.....i give up!! i have a question joolz,as you work in the industry,how much torque and speed will the aluminium tail shaft take on the xr8,i am thinking of a few mods but to replace the t-shaft could be about $1k,can you supply specs on stock? thanks topic ----- should be sticky posted

As ive said before the we test the alloy shafts for fatigue at 1200nm, it takes around 150,000 cycles before they break. Basically they are strong enough to handle what the XR's can produce in torque. I will have to find out what the speed rating is for the standard alloy shaft.

didn't tear the chassis at the cross member, however, the tailshaft did make a few perforations around the end of the tunnel near the diff, with some good sized dents.
Soon to be fixed.

Im assuming in these tests all parts are in at least reasonable condition (at least visually). I dont suppose many will fail off the production line, but put a few 100,000k's on the uni-joints, bit of free play in the output shaft of the gearbox and some vibration through the drive train of other parts not in new condition and things might start giving a lot sooner. Mal Wood also posted on another forum not so long ago that the alloy tailshafts fitted to XR's are very easy to damage. It might only take a stone to get flicked up, take a chip out, and they are structurally weak.

With the exception of re-treadsre-moulds I didn't think you could buy tyres rated that low.
