primary spring guidance please

[morepower=morefun]

We're up at camp and trying to help a fellow Viper turbo owner RAISE his engagement about 400-500 rpm's. My manuals and spring charts are back home, but we do have a good selection of springs in the trailer. Would anyone KNOW which is next spring from the BLUE/SILVER/BLUE to RAISE engagement.

Thanks so much for helping. Hope you all get snow soon if not already!

Blue-green-blue. 40 kg preload, same spring rate, 106 kg total force compared to 101 for blue-silver-blue.

Thank you SnoNinja! and shagman and cannondale27 for confirming! This is a great help, pretty sure I have one right in the trailer. Really appreciate your speedy response and this Website for making it so easy to gather USEFUL information. We'll give it a try this morning, as we got a little distracted last night trying to wear out the hinges on the new beer fridge... a little muscle therapy after a 190 mile day... ahhh
