Why? The original driver's seat was very worn out, and it drives me nuts when a seat has slop in it. The cover was torn, lots of slop, and the cushions were long since beaten into submission. Why e90 seats rather than the more popular e36 seats? Age and price. I got these for $250 delivered, and since they came from a car newer than 06, they are in much better shape than any e36 or e46 seats I could find. I didn't realize I could get e90 seats in manual, I assumed they were all power, but these fit the bill perfectly. I'm guessing from the manual controls these are likely leatherette.Normally I wouldn't have bothered with seats before doing the steering rack, sway bars, etc... but I found these at a good price and decided to jump on them.
In retrospect, fitting them was pretty simple, 2 plates on each side, just had the find the right position to offset these seats, put the old seat belt clips on the new seats, and it was all set. However, it took me a while to find the ride position, due to interference from the original mounting bolts, so I ended up having a shop do 2 sets of adapters for me. Ended up costing about $150. I could have just bought bar stock and drilled it myself, but at the time I didn't know it was going to be that simple.
They look great in the car. At some point I'll have the rear seats redone to match the leather on these ones. Total cost for seats, shipping, several versions of mounting plates, and hardened bolt hardware came to about $425.
