Which supplier has the correct APR connecting rod bolts of 2.0 rods?

AirCooled doesn't carry them.

CB Performace has APR bolts but I don't know if these the correct/best ones.

a longer rod doesn't change CR because it is ALWAYS LONG.

Ahh, I was going to argue, but now I understand. Modifying the rod will change the uncompressed volume and the compressed volume by the same amount. i.e. A smaller amount of air/fuel is being compressed into a smaller space. To bump CR you need a larger (or same) amount of air/fuel being compressed in to a smaller space.


I suppose one could argue that there is a miniscule CR increase because the % of volume lost at BDC does not equal the % of volume lost at TDC. But I'm splitting hairs.

4 in^3 / 2 in^3 = 2:1 ratio
3.998 in^3 / 1.998in^3 = 2.001:1 ratio
