There are many incidents where I watched mechanics or drivers retighten their wheels after each special stage / heat, and they were always complaining how their wheels come loose during hard driving. Those were typically also the people who later complained about wheel studs breaking. Reality is, as materials get hot, they expand. Typically, the wheel studs/bolts get much hotter than the wheel, as they protrude into the hub and rotor, while the wheel itself is actually acting as a heat sink, giving the heat energy to the surrounding air. That means the stud/ bolt will expand in length more than the wheel expands in thickness, making the wheel nut / bolt feel under tightened every time you check them hot. Keep snugging them up, and eventually you will reach their tensile strength limit after all parts have cooled down again. Checking the wheel torque twice a day is enough, imho; once first thing in the morning, and the second time after the lunch break, but most importantly: when everything has cooled down again!  

Yeah, I don't think accurate torque specs for ANYTHING call for the surfaces to be hot... That's nonsensical. Not to mention removal afterwards might be even tougher when the studs/bolts have contracted after cooling down.

I have a pair of Piloti and Puma driving shoes. Both are great for pedal feel, but they are very slim which can make heel/toe more difficult, but almost never experience an instance of accidentally hitting both pedals.    The Puma were significantly cheaper and seem to have better grip on the soles, so I tend to use them on track more, while using the Piloti for street driving. 

I've always torqued my wheels before the first session of the day, and then checked wheel torque the morning following the last session, so only when not hot.  No empirical evidence for this, but metal is more malleable when hot, so I suspect that performing additional torquing when hot could result in unintended metal fatigue. 

It’s not uncommon to see drivers torquing their wheel nuts immediately after a session. I’m hoping someone out there has a definitive answer on torquing wheels when hot. I asked AI (Artificial Incorrectness) and they said DO NOT torque wheel nuts when hot. That’s always been my assumption but AI’s response to the resultant effect was “could result in over-torque or under-torque”. Maybe it depends on the specific wheel components and mounting configuration? Regardless, it would seem best to NOT torque the wheels when hot. Has anyone done testing to prove one way or the other?

Beauty, can I come take a look? 204-806-8514

Hi Folks,  here's a little rear view action from the fall track days event (Sunday).  This is my '06 Solstice Mallet.  Doesn't sound quite right because of the crappy bluetooth microphone.  I think it might be Glen's '26 Porsche 911 Carrera 4S (?) that's behind me.  Anyways, a fun day and a great season wrap up.  

I keep breaking axles in my ice racer. I'm looking for an expert to help me figure out what's going on and to possibly measure for a custom ordered axle. Any help is appreciated. 204.dot.612..3681

Thank you, Sir. I appreciate that!  

Lol, yeah, that would not be the right sole!  Man, you got every ounce of power and handling out of the Veloster...great driving!  My power to weight ratio must be almost 2x the Veloster and you were all over me - very impressive!
