OK, I have a set of the 4 inch BDS lifted springs that I'm selling and they have 3000 kilometers on them (about 2000 miles???). I bought them last year and they've been sitting in the garage since then because the Zuk is getting a major re-do. I'm selling the springs because I'm dropping in a HEAVY drivetrain (4.3L, 700R4, NP241, etc...) and needed larger springs to handle the weight. These springs are a great swap and I was very happy with them for the time they were used. And no, they are not as stiff as some say, in fact, they are better than stock.
I have the U-bolts (never used b/c I used my old ones), and other hardware but I wouldn't recommend having them shipped because of the weight. The springs have the bushings and sleeves still installed.
Now, I live in Ontario, Canada but I have looked into shipping via Canada Post's parcel service. I ballparked the springs weight at 20 lbs each (my scale said around 18-19 lbs each) and when using their rate charts, the shipping of all 4 springs, (not including the U-bolts) as 2 separate parcels, would cost about $100 Canadian, or $70 US. I would be willing to sell the springs for $150 US, so the total would be $220 US shipped for all 4 springs. The shipping rates are based on the furthest destination from me so it could be considerably less if you fall into a closer zone to Ontario. E-mail me if you're interested and it's a first come, first served basis.
