The base itself isn't longer, but the cushion is and sits a little higher in the front. Raising the front with washers is a great idea and one that I may still do. For me the seats are so much more comfortable than the stock ones.I'm looking seriously at doing this, even found a good deal on seats that I can pick up this weekend, but I have a couple of questions:
Are the Speed3 seat bottoms longer than the 5 bases? I think I've isolated the comfort problem I have with my 5 to a total lack of any support under my lower thighs, from the combination of the seat being too low in the front and being too short front to back. I know people have raised the bases up in the front, and I'll probably be doing that whether I keep the stock seats or switch to the Speed3 ones, but I think it would really help me more if the seating surface was longer/deeper, too.
Thanks! I've reached a point where I'm thinking about selling the 5 because my knees hurt every time I drive it, and I don't really want to do that!
I'm 6' 1" and sit with the seat all the way down and about next to rearmost position (1 click up) this leaves about 2" between my knees and lower dash which is a comfortable seating position for me. Modifications would have to be made to the speed3 tracks to bolt into the five. I actually feel like I have more room in my 5 than I do in my wife's CX9.how tall are you loosenut? i'm 6ft and find at the lowest and farthest back the stock seats sit me far too close and high, so if anything i would like to swap in the speed3 seats using their bases so i can be a little lower. i will be driving my 5 a lot more and as it stands now its very uncomfortable for me for anything more than 30minutes. i've always liked the speed3 seats so finding this thread today was great!
I still think the seats were the best investment I've made in the vehicle.
