So far, any Ractive products that I have sold/installed, I have found to be good quality. However, I have not sold or sat in their seats yet. In the pictures they look like they are constructed well and durable, yet I have a feeling they might not weigh much less than an oem seat.
Most of you who know me know that I'm strict when it comes to quality and I stand behind the products that I sell. I think what I'll do is order a pair of these, weigh them, and install them in my Mystique so that I can test the fit. In the meantime, like I said in the first post, let me know if you'd be interested in a set if the quality/weight/price is good.
