A while back I purchased a set of Rennline pedals for my 997 Turbo through CoolCava Racing here in the UK. This was to help me with heal and toeing given the very high biting pedal for my ceramic brakes - I just couldn't reach the throttle without full braking all the time, something that I rarely do on public roads.

2 weeks later and they arrived!!



Thursday evening I set about installation. I put together the throttle pedal as much as I could prior to getting near the car itself, this was pretty straight-forward and could be done from the comfort of my desk.

Starting point:



I then drilled the 3 holes required for the lifter plate using the cut-out template provided in the instructions. Sadly though after drilling the holes the bottom left hole was about 1cm too low and too left - so I had to drill another hole! Not to worry I suppose as the lifter plate covers the mistake hole anyway...



Next I screwed in the lifter base plate:



Followed by the main pedal (constructed earlier):



Next up, the brake pedal. I was scratching my head for a while how to get the stock rubber grip off, then I found that the whole thing is just a rubber cover for the pedal which you can just pull off from the back:



So once I got that off I then had to drill some holes for the screws. Frustratingly though this was very hard to do as the angles are really tough to get at with a drill and this pedal is made of metal so it slipped each time, and again afterwards I found my alignment of holes slightly out



After getting the hole right the next issue then was tightening the screws into the bolts behind the pedal - especially as my initial holes were too close to the vertical metal stem of the pedal so the bolts wouldn't fit. It took me about 1 hour just for this part alone!!



By the time I got this far it was getting dark so I decided to abandon the last pedal (clutch - which looks like it is plastic not metal) for tomorrow. So I went for a little drive to test them out.

Immediately heal-and-toeing was SO EASY!! The brake is right level with the throttle now, I can 'blip' under any braking load. It's great. The only thing to watch is under heavy braking it's very easy to catch the throttle pedal so you have to be aware of this. Just needs a little practice I suppose.

 

Report part II...

So this morning my brain finally kicked in and I realized that what I needed was a MIRROR to see the back of the pedals. D'oh!! This helped massively, especially when planning where to drill the holes and for tightening the bolts at the back.







NOTE: I also spotted that the Rennline recommended top-lower hole (for a 997) was actually restricting the throttle pedal at the back. That's like 50bhp gone right there!!



NOTE: So I switched to the (non-997 recommended) top-top hole to resolve the issue, giving:



Final result:





I then took the car out for another drive and after I re-adjusted the pedals a little more I was no longer catching the throttle when I applied for full brakes. Now it rocks - I love this mod!!

 

The pedals look fantastic.

Sounds like it was a bit of mission to get everything aligned, but looks like the results are more than worth the effort.

 

Hey man the controls are on the wrong side of the car...

 

Very nice work, that's my next project.

 

I love the clean look enjoy it

 

Thanks Alex; I also thought there was something subtle when I floored my just installed Rennline throttle pedal. Seemed the range of motion was limited. After looking at this thread in more detail; I went to investigate and found the same lower self tap screw on the upper throttle pedal hitting the stop by 5mm to 6mm. I'm sure that's about 50hp lost, just fixed and can't wait to drive it again! Why does Rennline recommend the lower hole on the upper throttle pedal is beyond me.

 

If any of you should go for the dead pedal cover like I did (covering up my $250 optional dead pedal), you may find that some of the little rubber ******* will pop out with heavy pressure on the pedal. I resolved this by placing washers between the old and new dead pedals.

 

Yes, I found the same for the lower 2 self-tapping screw holes also. The recommended lower set of holes mean drilling into metal. The upper set are much better I found.

Really glad I double checked this.

Any chance you still have pics of your pedal install? Links are broken

 

Pic links all fixed now.

 

Excellent!!

 

When I first installed my Rennline gas pedal, I had little practice with it and went to the track. I too was catching the gas while braking. Let's just say there were a couple of stops from 145 that had a high pucker factor combined with a "what the hell is wrong with my brakes" feeling. Once I got the hang of it, it was a huge improvement over stock.

 

Thanks a million Alex. Page is bookmarked. Now just need that drill..... If I knew how to rep, I'd give you several!
