Formed with ABS Plastic the panels follow the shape of the car and are covered in matching black carpeting. The lower panels are very solid and can easily hold well over 60 lbs. ABS Plastic does not deteriorate, crack or bend under pressure. It does not have the forest products smell of other wood-based kits. Weight savings is 13 to16 pounds depending on factory seat material and the year and model. Color instructions are included and the kit installs in 20 min or less. It fits all Mustang models 05-08. The MSRP is $249.00 with free shipping. Contact Shrader Performance at (704) 674-6979 www.rearseatdelete.com
