Another performance oriented upgrade that can shed anywhere from 10-50 lbs or more weight out of your Mustang is replacing the factory seats with a set of aftermarket ones. Aftermarket Mustang seats typically get bolted right onto your frame to provide you with a fixed driving position that is a perfect fit for you.
Some seats use a fixed back while other offer a reclining back, but if you are going for a race seat you will want a fixed back. The firmer you're planted in your seat during a race or a drag pull, the less you'll have to focus on keeping yourself positioned and the more you can concentrate on your driving. There are some in-between options that recline, but also sport large side bolsters to keep you in place. While also being comfortable, the in-between seats also have slits for racing harnesses.
Continuing on the performance theme, if you are racing your Mustang one of the necessities for racing on the track is improving your belts and harness system. While the factory belts use a 3-point belt system with 3 points of contact, aftermarket belts can come in 4, 5, and 6-point harnesses that will keep you snugly held within your seat.
Adding a set of aftermarket belts will require you to properly anchor them to the frame so that they hold up in a crash. You will also want to make sure whatever belt you buy is DOT approved if you plan on driving your Mustang on the street with it as some belts don’t provide the proper protection in your average, low speed crash.
You can also shed weight and clean up the look of your interior by deleting the rear seats. A Mustang rear seat delete kit will transform your Mustang from a 2 2 seater into a sleek and lighter 2 seater.
