Currently have a set of "mystery" STI pink springs in my possession, and I'd love to positively ID them before I put them up for sale (I'm looking for USDM STI takeoffs to match my GR-2 struts).
I have a thread going which seems to indicate that they may be "Tarmac" springs: http://www.clubwrx.net/forums/suspen...k-springs.html
That said, I have no way of knowing the actual spring rates other than the "Some guy on a forum told me..." line.
Anyone know of a local (MA/NH/RI) performance shop that could help me identify the rates for these springs?
