I'm looking to try some higher rate springs on the Van Diemen, and rather than blindly buy, I'm hoping to borrow and try.

My arithmetic suggests that the ideal number would be 1386 lb/in, but since that's unlikely to be available, I'll take anything in the range stated, or even a little below; even 1200 lb/in might work better than what I've got now (1000).

For length, anything from 5" to 8" might work, but 6" would be ideal.

Anyone?
