I would say set in one before you buy. The poly seats are one size fits all. I'm here to tell ya my butt don't fit that well in a poly seat, very uncomfortable .It might be OK for a few minutes at the track but I drove my daughters Jeep about 1/2 mile and couldn't wait to get out of it. Kirkey aluminum fits and is comfortable in the proper width, 20 lay back for me. Just my opinion, others my differ.
