I have a brand new set of BC coilover for Infiniti EX35 AWD in my garage still packaged up in the original box, never removed from the box. The EX35 has been gone for a year and these are simply taking up space.
Here are the specs.
This is for 07+ EX and BC part number is v13. The coilover type are the BR-RS Extreme which is a decent drop.
Front spring rate is 12 Kg/mm
Rear spring rate is 10Kg/mm
The cost for these new was about $1,100 shipped. I will take almost half of that $700, you pay shipping which i bet will be at least $30 (not sure though).
Example of what the drop could look like.
