Well I know it does not look the best, but REI had a sale on all Yakima products and I bought a roof rack for my Speed3. I had to buy two seperate pairs of Q towers. One pair was the 99s and the other pair were the 34s. You guys who have put a yakima roof rack on your 3s or Speed3s, which pair goes in the front and which pair goes in the back? The Yakima fit guide and website was not very helpful. Thanks
