So I've been wanting to upgrade the pedals on the car but could not find anything decent. So during my search I came across a company that made Porsche pedals. When I called him to see if we could do something custom he tells me he was a Viper owner in the past and had some designs done for them! Even better he had a set for the GTS done! The company is SRP Racing. They are machined in the USA by them. Great pedals! I got the following set. The brake and clutch are identical with an aggressive pattern on the tread. It is impossible to slip off the pedals. The accelerator is dead smooth with the heel/toe extension. The smooth finish lets you slide your foot on the accelerator pedal. A some for heel / toe driving. While I have not tracked the car, I can tell you it was awesome to drive on mountain roads in Virginia. The pedals... The pedal surface detail. The nibs are very sharp and they work perfectly to eliminate all slippage concerns. Not going to get into a huge amount of detail but let's just say I took a great deal of care to get alignment perfect. I did it with bright masking tape so I could see it through the pedal's holes. I then clamped the pedals in place. From there I marked (with a punch) and drilled a pilot hole on the brake and clutch. I then drilled the hole to the required size and bolted them in place. On the accelerator I aligned and drilled pilot holes for the screws (wood screws provided). I then placed two face molding tape on the pedal and then screwed it down. Between the tape and screws, it's not moving. This is a shot showing how I used the tape. Below is the shot of the installed pedals..
