12 spoke spindle mount Radir wheels?

 

[Indycars]

have another couple of questions on bolt torque values. The first picture is for the 1/4"-20 bolts with new Nylon lock nuts that attach the front rotors to the inside hub. I am thinking it should be around 90 in/lbs. Pictures 2 and 3 are the 5/16"-18 bolts that attach the inside hub to the wheel. Here I think approximately 15 ft/lbs. I looked a some different bolt torque sheets, but I do not know specifically as I do not know what brand the wheels, hub, etc. they are. Your help is appreciated.

Do you know where those socket head fasteners came from??? China Maybe???

I would highly recommend that you go to ARP and buy something from them. Install the fastener with an anti-seize since you are dealing with aluminum threads. ARP will have their own specified torque values.

THINK SAFETY !!!

Since we now know who makes the wheels you can go to Radir where they say .....

Are you sure they're radar wheels? They're certainly different than mine. All the radar wheels I've seen have 4 threaded holes on the back and they are used to mount the brake rotor.

Back in the old days there was a motor driven wheel that would sin the wheel on the car. Don’t remember how they indicated where put the weights.
