VBP Performance Plus Spring rates?
For those who are running the VBP Performance Plus system, what spring rates do you have? BB or SB?
If you don't know, it's written on the springs as a 4 digit code I believe.
Thanks

I asked this question to VBP and got this reply:

BBShark,
The 7717-1 and 7735-5 numbers are our in house production numbers. The first 4 digits is the spring slab run, the last number (1-5) is what position on the slab your spring was cut from. The 600 and 238 numbers are the spring rates (Lbs./in.) when bolted on our fatigue and safety test machine. These numbers are lighter than the actual spring rates at the individual wheels as the tester does not hold the spring at the same points as the front and rear transverse system brackets do.
