I am going to go with a set of Stance coilovers since i am the Canadian retailer for them.
i have a set of good condition D2 coilovers for S13. No dampers blown, i replaced them recently.
also have replaced the springs with QA1 , grey powder coated springs in 8/6 rate equivalents, i cant remember what the lbs / in was.
best over $600
basically looking for $650 cdn but $600 usd doesnt even equal $650 cdn anymore so best over 6 bills usd.
please note that they are installed on the car right now.
Here is a picture comapring the old ghey D2 springs vs. the QA1 springs.
