I've got a set of Recaro LS-L seats from an '88 Alfa Romeo Milano in my G20. It was a challenge having to fabricate brackets in order for them to fit into my G, but they are soooo worth it. The difference in comfort and support is night and day over the stock G20 seats. I've taken long road trips from San Antonio to Naples-Atlanta-Pensacola (3500 miles round trip....)and have driven hours with little to no lower back or leg discomfort. When the G20 had the stock seats, I had to stop every 4 hours or so to stretch.

That said, after having sat in the OEM G37S sport seats I can say that they are the closest thing to the same level of comfort and support to Recaros or another aftermarket seat that you can think of. I say don't bother changing them out. The $$$ and trouble of swapping out the seats for something a little better and a little lighter just isn't worth it.

 

i've got a set of bride brix ii's in my civic and it does its job with holding me in one place. now as far as comfort is concerned, my friend has recaro speeds in his car and those are nice as well. i'd say the recaro's are more comfortable for everyday driving, while the bride's are ideal for the track
