Maybe the spacer requires additional torque or retorquing?

Why are you running a spacer?

I haven't heard anything about retorqueing, but I personally would feel better knowing that the spacer won't be causing me anymore break downs, especially going into what is typically the coldest part of the year. Last night was almost 20*, but with the wind it felt like -10*. Now if it had been -10* and that wind I really would have been hurting.

Good question. I guess it'* mainly because I got it with the ported and pullied SC. Good thing I have a spare set of shorter studs to attach the TB to the SC I'd really be kicking myself.
