Is that to French spec rather than German?

 

I asked the dealer for this info, but they were less than helpful as usual...

I don't know if I would believe the dealer at this point since I had to convince the parts manager that our cars have 1 wheel speed sensor per wheel when ordering the parts for the job. They thought anti lock brakes only needed 1 wheel speed sensor for the front & 1 for the rear?!?

 

so they were confused.

But on the arms being fragile, who here has heard of an Al arm failure on our cars? I haven't heard of any. And many have correctly posted that tons of cars (especially high performance cars) have used Al arms for quite a while. I don't know if I'd worry or not if I were running a race series, but for the street, I'd never worry about it.

We ran them all year long on the race car without any major issues.

You'll see them on the R56 Challenge cars.

If you have to remove your shocks / do frequent spring changes, just be careful with the lower shock bolts. It keeps machining itself. We had to heli-coil ours.

 

The rear end of our Coopers is very robust and over-built considering what is asked of it.

I ran close to 500 whp through my alloy arms on my 911 race car and that was rwd. Never a problem with the arms. CV joints were always BBQed.

We really don't ask a whole lot of the rear wheels on our Coopers. All they really do is follow the the front wheels and with a little input "not pass them'

 

I've never said aluminum would break- I'm the one who said all OEMs use alloy suspension pieces in some of their cars & trucks.

All I'm looking for is torque specs for the bolts so I don't ruin the new parts over the Turkey-Day holiday ; )

 

Had a peek at a MINI Repair Manual for the R56 and now have the TQ values for all the bolts.

Upper Control Arm to Trailing Arm 100Nm
Lower Control Arm to Trailing Arm 100Nm
Control Arm to Rear Axle Carrier 100Nm
Holder, Trailing Arm Bearing through Trailing Arm 165Nm
Holder, Trailing Arm Bearing to Body 100Nm

 

THANK YOU GNATSTER!!!
