I've sat in those seats from Jegs... the later support is not bad, but could be better; the price is very good if you're looking for a low-cost seat that is better than our factory seats. There are much better choices available... seek and you will find... I looked for 2-3 years before I made a final decision. I have a Corbue GT8 driver's race seat (fixed back/non-adjustable -- superior lateral support, well padded/comfortable to driven cross country, 18 pounds without brackets.. I adapted the factory mounts). I also have a matched pair of imitation adjustable Recaros ... from JCWhitney (good low prices... I went to their warehouse while they held a big car show and sat in a few different seats... they even pulled some from their warehouse for me).. high lateral support both lower hip and upper sides... a little stiff in the back, but.. I've simply added a pad that fits lower and back for added comfort when driving long distances (take em out when on race track).... and... only ~28 pounds each. Our factory seats (E-B) are ~45 pounds each.. and offer poor lateral support.

Corbeu, Sparco, and various other name-brands offer good choices... take your time and test-sit in them... at trade shows, races, etc. Spending a little more is worth it in the long run, as well as spending the time to find the right seats.

I suggest choosing "high" lower and side lateral support... most seats don't truly offer them, despite their appearance. Also, adjustable features add comfort and value.
