Well, for what it's worth, I didn't think the sills were hard to remove at all using a heat gun and pliers. Taking my time and being extra careful, it wasn't even 10 minutes a side. They will not be reusable though, so you might want to consider getting a set of spare OEM ones from Torrie if you ever wanted to be able to set your car back to stock. On the other hand, I LOVE my P321 door sills, and like Rocketman, I HIGHLY recommend the door sills, the engine caps and the coil covers to anyone that owns a GT.
