Does your Tarmac have a pure PF30 bottom bracket shell (68 mm wide w/o cups) or that 'carbon shell' version of Specialized's many OSBB versions (61,5 mm wide)?

In the latter case, you may need some additional spindle washers.

Also, are you aware that special tools are required to install/remove the spider(ing) as well as pulling the crank arm off the spindle? (For the latter, there is a work around: using a square taper/Octalink puller with a DIY adapter bar that goes into the spindle and shores up at the crank bolt at the opposite end.)
