Everything I've seen and read including manufacters recommendations for the shoulder belts is mount them even with the top of your shoulders when seated to no more than 4 inches down from a horizontal position even with the top of your shoulder.....

Mine are about 2 inches down from the horizontal position, I was told by many experts, including NHRA tech experts, that you want the belts slighty down from the top of your shoulders to put slight downward pressure on you to hold you down in the seat in case of a roll over..........

Too much downward mounting will cause the spine compression you speak of.....that's why they recommend no more than 4 inches down from the horizontal position..........

Use top of the line hardware, good belts do you no good with el-cheapo hardware that will not hold up to an impact...........
