Default Gas pedal mount

I began today to install an aluminum gas pedal mount for my 1993 Ruby, which I use for track days. As you know, the stock mount is plastic, and does not hold up well under the stress of heel and toe shifting.

Upon removing the stock pedal assembly (shown in photos below), I notice that it has an angled piece attached to the outside of the mount. The right side of the angle faces against the mount, with two bolt holes. The section perpendicular to the mount fits against the bottom center of the pedal lever (below the pivot pin) and acts as a stop, possibly to prevent excess pull on the throttle cable.

My aftermarket aluminum mount has no such stop.

Is the lack of a stop a problem? Is the throttle cable protected from excess pull on the opposite end?

Or might my extra cable travel translate into higher / better throttle performance?





Advice / info will be much appreciated.

You won't get any better throttle opening that is for sure. I don't think it will be a problem. Mine hits the floor so that stops it. I keep a spare stock assembly with me when I'm at the track or at an auto-x.

FYI, looking to do Track Night in America on June the 8th at PIRC. Doing the Great Lakes Muscle Car Challenge at PIRC the weekend before that as well.

I have an aluminum pedal mount and the pedal hits the carpet before the throttle body gets completely open (and hits the stop).

Hey Rubie. I always appreciate your advice.

Since my replacement effort is preventive, I will save my stock unit as a spare. Hopefully, with the upgraded mount, I'll never need to change it, but the best way to ensure that is to be prepared....

My first event this year will be PDE at PIRC on Sat April 16.

I might see you at Track Nite June 8. Still considering that one. Do they run different skill groups? I ran with them once last year on the first night that the new track was opened. If they ran groups, I was downgraded to novice. It was a zoo.

A combination of heavy rain, green track, and untrained rookies made for a night when the goal was simply to stay in one piece. I think there were 35 cars on track together, and at least 7 of them went off track over 3 sessions. Every session was interrupted. Some guy in a a new Viper did a 360 right in front of me in the south straight at the new paddock. That straight has a dip in it, and there was a stream of water flowing over it. He bounced both the front and rear of that Viper off the wall. I doubt that he drove it home.

Thanks. That seems to be the norm. I will stop fretting over it.

Mine broke at an autox 150 miles away before it became a trailer car. I had to operate the throttle by using the cable by hand and it hurt after a while. I now carry a spare.

Yes, Track Night in America runs different level groups. I did novice since I had not been on that track before. By the end of the night my buddies (much more experience) where saying I needed to run advanced run group. So I expect to be in that one or intermediate at worst. I won't run Novice again...too many idiots.

They are hard to find. Someone use to sell them here on the forum but he disappeared a few years ago.

I bought my mount used from a fellow forum member who crashed, totaled, and parted out his C4 track car. He even included a spare stock pedal assembly. Thanks Shrek!

Ouch. A breakdown at the track is no fun. My Opti crapped out on the first morning of a 2 day track weekend in Nov. Bummer. But at least I trailer mine, so once I loaded up, I was able to drive home in comfort.

Can't even imagine driving 150 miles with hand controlled throttle cable. That's improvising.

installation went well. Pedal does not bottom out on the floor, and throttle travel is unchanged. It's all good.

Mike Bohannan (vettmike) was the original designer.
Mike passed away several years ago and i've not seen another mount offered since then.
