  • Tensile strength of the 8.8 grade is 800mPa or 116,000psi 
  • Tensile strength of the ARP (8740 chromoly) is 1310mPa or 190,000psi 
  • Tensile strength of 12.9grade is 1200mPa or 170,000psi
That's a 63% increase over 8.8 grade, and a 10% increase over 12.9 grade.

The  other factor to consider here is - all grade 8.8 and 12.9 bolts are coming from China.

You really do have to ask yourself...are they really undergoing continuous quality control in terms of yield tensile strength? Most people will realise ARP are

This is the very reason Motorsport and performance applications use and trust ARP
