Does anyone know the difference between these two HHR SS Seating options:

AR9:
Seats, front bucket, Premium Cloth with Ultra Suede inserts, high bolster seatbacks, SS embroidery and color-keyed accents, includes 60/40 split-folding rear seat.

AE4
Seat, driver, Premium Cloth with Ultra Suede inserts, GM Performance Division, high bolster extended length seat cushion, high bolster seatback, SS embroidery and color-keyed accents.
1-Front passenger seat and rear seat are the same as (AR9) Premium Cloth with Ultra Suede insert front bucket seats. Driver seat cushion and passenger seat cushion will have a complementary appearnce but are not identical in color scheme, size or shape. (etc, etc)

So, does anyone know what the deal is with this "mismatching driver seat?" I opted not to order the special drivers seat, but don't really have a clue what it is... will I regret this?

 

I think that's what's vilible in the printed brochure, and to a lesser extent in the pic on the HHR SS website page

The seat bolsters on the two seats are not the same depth or profile.

 

The seat back bolsters on the pass. side are shorter on the SS, just like the normal HHR to facilitate folding flat.

 

yeah the extra torque as long as you dont go past 300 hp is ok just make sure you get motor mounts or the ingall stiffy is good
