Likewise haha, the boxes mine came in were a Frankenstein of random boxes. when I got my blues, I was asked what I was going to do with the car and they recommended spring rates based off what I was using it for. They actually recommend 14kg up front and 8kg at the back. I thought it would be slightly too hard, so I decided on 12kg up front and 7kg at the back. After many spirited driving sessions I regretted not going the 14kg and 8kg so I bought the set they recommended for extra ($100 per pair). Loving them since, bit stiff for the road but perfect for the track and mountains. Edit:- I wish I wasn't broke at the time and went for the reds also, given how good the blues are for the price I could only imagine how good the reds are...
