64 cadillac 4dr air line size

[64sdv]

Hi i'm in the middle of my install and I'm having second thoughts about the valve/air line size I went with (1/4''). The car weighs around 4550lbs, should I have gone with the big red valves and 3/8? It seems like 1/4 would be really slow.

The 1/4" should give a car that size around 6-10 seconds rise time (from deflated to ride height).

I have a 1966 Lincoln Continental Convertible (5500lbs), which has BigReds and 3/8" air line. Though the front is fine, I actually wish I had used 1/4" on the rear.
