I placed an order via the website for a driver side bracket to fit my Recaro SRD's, I received a call from an individual at Wedge asking if I had the 4 or 6 hole sliders, I stated that I had the 4 hole version and he said that he knew what I needed, the bracket is delivered with a week, really pleased with the turn around, I install the bracket to the slider and it is too short (does not line up with the bottom holes). I call Wedge, they ask for pictures, I email the pictures and I get a response from Zach with Wedge stating that I gave them the measurements and suggesting that I drill the slider to fit the bracket, I respond stating that I did not provide any measurements and asking that we work together to sort this out, have not heard back so long story short, avoid Wedge Brackets
