So I just got my new fortune auto coilover with swift springs that I requested with 10k front and 12k rear springs. Well when they got here today i opened up my box to find 12k front and 10k. I wanted to know if anyone knows how much of a spring rate change is ok before revalving . So if i just switch my front and rear springs will I be ok or do they need to get sent back to fortune auto before i even get to install them.

 

I think there is a 2K allowable variance in most valve setups, but please call this into FA & let them know what happened

 

I sent them an email and will try to call on Tuesday since it is a holiday weekend and it was to late by the time i got home.
I am pretty sure it will be fine with just swiping the springs. From looking at the certificate of assembly it looks like the front and rear have the same valving profile
