does anyone know what this is? Ive read the manual but cant find it. I have the racing wheels.
thanks Ive just asked a dealer and he said 120nm (88.5lb ft) for std and 150nm (110 lb ft) for carbon wheels. Its difficult getting a definitive answer
I’ve now separately got 2 dealers stating 120nm but no reference to whether it’s steel or titanium bolts so I assume it doesn’t make a difference unless someone else knows
i have 120Nm written down in my notes for track days, however i don’t remember if i got the number from my dealer or elsewhere… fwiw i have titanium bolts
Strangely enough, it seems the only torque information provided in various owners manuals (for different models) is for the optional spare wheel; it comes at 100 Nm. The spare wheel is smaller / lighter than a regular wheel, and speed is limited when using it; so it would make sense to have a higher torque for the regular wheel - but since the lugs / threads are the same, they cannot be a lot higher... So 110 or 120 Nm seem to be a good ballpark. Older cars (e.g. 550 maranello) specifically mention 100 Nm (not restricted to a spare wheel), but IIRC that's typically considered too low. I realize how good I am at providing limited information with that many words
Bolt material should make a difference all else equal unless Ferrari designed the bolts in such a way that the torque figures are equal. Titanium is softer and stretches more. So unless Ferrari made the titanium bolts to have a different thickness and length, I wouldnt blindly torque titanium bolts to the same amount as stainless. Or you are undertorquing stainless steel bolts.
