And, joking aside, you should look into another book from the Speed Secrets family. I was fortunate enough to have had some coaching by Ronn Langford, who has extensively worked with Ross Bentley and has coached a number of pro drivers that have gone on to win many championships. It is not about driving technique -- it is about how the human brain works and how a few simple exercises can maximize your on-track driving performance. The title is Inner Speed Secrets: Mental Strategies to Maximize Your Racing Performance, co-authored by Ronn Langford and Ross Bentley. Check it out if you get a chance.
Trending Topics
1. What are the weights for the DOM cage, and for the 4130 Chromoly cage?
The DOM cage is about 70lbs, and the 4130 chromoly cage is about 50lbs
2. Do you have more photos of the points of attachment to the car body?
We do not currently, but the photos that Paul provided in his last email are the best we have on file. As we're one of the few, if not only, companies manufacturing a C63 cage, I try not to share pictures of where exactly we mount to. I hope you understand. Rest assured, we dedicated a lot of time in Research & Development using our experience to make sure the cage is mounted at fully functional points while still retaining ease-of-install.
3. Any drilling into body necessary, or does it utilize factory holes?
The front main hoop does require drilling into the rear seat bench/frame cross member. We provide specialized hardware to make the installation much easier.
4. Any photos of your C63 Rear Seat Delete, offered in Carbon Fiber or Aluminum panels with suede fabric overlay?
I'm currently debating whether to offer the delete in Carbon Fiber, but since we've had about 3 requests in the last month, I may go ahead and do so. For now, we only have it in suede as seen in the pictures in Paul's email.
5. What are the weights of the CF rear seat panels, vs the Alu panels?
The aluminum panels only weight about 10lbs in total for all 4 pieces.
6. If have a 60/40% split rear seat back and bench, do you have the option to panel just that 60% rear?
We do not unfortunately.
Regarding the Pano roof delete, we can do it.

And those “tire walls”.... where do you even start. They really shouldn’t become jumps under any circumstance.




Nice guys, they sound like they know what they’re doing.Rear seat delete was a little pricey in my opinion. I might just pad/carpet the bare metal areas and save a few bucks.
Having it.... customized a bit to make it safer too, with some optionality to convert it to a 6-point down the road. Stay tuned.

deadlyvt - the non-panoramic sunroof doesn't weigh nearly as much as the pano so I can't see a huge advantage in getting rid of it on a DD. The all-glass pano on the other hand adds about 250 lbs at the highest point on the car and considerably raises the car's CG in addition to sacrificing chassis stiffness.




Weight savings are in the order of 180lbs for the full pano coupe roof with associated motors, glass etc.
I know Vladds posted up the MB part number on one of MBNRG’s threads. There were certain Euro and Japan base C-class coupes that came with a solid roof. Just need to track one down now. Does anyone have access to an MB inventory search tool for Europe? There have got to be stacks of them in a warehouse somewhere in Germany to make OE repairs to cars of the volume that the W204 C-class was produced in....




I asked the Studio RSR guys about what kind of chromoly tubing they use for the rollbar/cage construction. My understanding is that typically DOM tubing is .120 thickness and 1 3/4” diameter, while chromoly is typically a lighter .083 and 1 5/8” due to it being stronger. Chromoly is also TIG welded vs MIG welding for DOM.
Studio RSR has told me that they use .095 and 1 3/4 inch tubing, and the bar is TIG welded in the structural points. That doesn’t exactly jive with what little I know about proper chromoly cage construction.

I’m a little confused by this. Does anyone know if it sounds right? While these guys sound like they know what they’re doing, I feel like I need to go over there and actually talk to the fabricator directly to get some additional comfort here that I’m getting what I’m paying for....
