Just A Reminder About Adding Shoulder Harnesses To Street Cars, Even Vipers

Somewhat oddly for the site that used to prioritize being FIRST POST above everything else, Jalopnik was last out of the gate with their review of the Viper ACR. I think it was worth the wait, because it was written by legitimate sports-car-racing hero Andy Lally. You can check it out here. As competent a racer and driver as I think I am, Andy’s obviously on the proverbial next level.

Which is why it made me sad to read one of the story’s last paragraphs.


Andy tells us:

Last but not least, if you are serious about buying this car please take these next words as serious as you will take any other advice. BUY THE SIX POINT SEATBELT UPGRADE. I did three flying laps in this car with a regular belt and had to pull into the pits because for as much grip as you can generate, a regular shoulder belt does not keep you in place well enough.

In Dodge’s defense, I was vocal about this right away and they explained that they are prohibited from selling a street car with these belts. They did have a car on-site with six-point belts installed and it was much more pleasant. The car is built so that you can easily install them. Check that box when ordering.

In Andy’s defense, I think he has about as much experience with “trackday specials” as I do with any kind of lambskin condoms. He is what they call a “real racer” who “really races” in “real race cars”. So when he gets in a car on-track it has six-point belts and a full rollcage and, more often than not, a monocoque designed to distribute crash impact.

The Viper ACR is capable of hitting a wall at a racetrack at nearly the same speed a World Challenge GT car could achieve. But it has absolutely no additional rollover protection besides what is built into the body. It is designed to roll over in a way that protects conventionally belted passengers. The interior is made of things that are softer than a steel tube. If the roof collapses because there aren’t enough steel tubes around the driver, the three-point belt will allow said driver to slide a bit to avoid said collapsing roof.

Unless, that is, you have shoulder harnesses, in which case your neck will be the fulcrum on which the car’s entire weight is focused. Do not expect to be able to resume your place in your high-school track team after that happens.

This is not the first time I’ve written about this. Nor will it be the last. Because it’s important for you to know. If, however, you happen to be able to drive a Viper ACR as quickly as Andy Lally undoubtedly can, you can make a change to your car that will bridge the gap between the loosey-goosey but rollover-safe feel of a three-point belt and the strapped-in immobilization of a proper racing harness. It’s called a CG-Lock, and it works well enough that Bob Lutz put one on his car when he and I did the CTS-V Challenge way back in the Stone Age.

And if you, like many TTACers, thought the Chevette photo was the coolest part of article, go check out Darren’s site, why don’t ya?

    "the three-point belt will allow said driver to slide a bit to avoid said collapsing roof" is there a basis for this assumption? after your original article i searched and every technical journal publication i found stated higher risk of injury correlating to a higher degree of the occupant moving around in a rollover circumstance. effectively suggesting that the three point is a compromise but the objective is to keep the passenger as still as possible. i raise the question genuinely as opposed to trollishly as i think it is a very worthwhile discussion, but predicated on that single important assumption.

      @JuniperBug i was specifically looking for research relating to restraint design and crash simulation for cars without roll cages in rollover conditions so they were typical passenger vehicles

    No matter how many times this site links its good pals at Jalopnik, I'm still not reading anything there. I hope this site doesn't become a hub for "Link this article and I'll pay you some ad revenue", I have public TV for advertisements.

  • Bd2 Lexus is just a higher trim package Toyota. ^^
  • Tassos ONLY consider CIvics or Corollas, in their segment. NO DAMNED Hyundais, Kias, Nissans or esp Mitsus. Not even a Pretend-BMW Mazda. They may look cute but they SUCK.I always recommend Corollas to friends of mine who are not auto enthusiasts, even tho I never owed one, and owned a Civic Hatch 5 speed 1992 for 25 years. MANY follow my advice and are VERY happy. ALmost all are women.friends who believe they are auto enthusiasts would not listen to me anyway, and would never buy a Toyota. They are damned fools, on both counts.
  • Tassos since Oct 2016 I drive a 2007 E320 Bluetec and since April 2017 also a 2008 E320 Bluetec.Now I am in my summer palace deep in the Eurozone until end October and drive the 2008.Changing the considerable oils (10 quarts synthetic) twice cost me 80 and 70 euros. Same changes in the US on the 2007 cost me $219 at the dealers and $120 at Firestone.Changing the air filter cost 30 Euros, with labor, and there are two such filters (engine and cabin), and changing the fuel filter only 50 euros, while in the US they asked for... $400. You can safely bet I declined and told them what to do with their gold-plated filter. And when I changed it in Europe, I looked at the old one and it was clean as a whistle.A set of Continentals tires, installed etc, 300 EurosI can't remember anything else for the 2008. For the 2007, a brand new set of manual rec'd tires at Discount Tire with free rotations for life used up the $500 allowance the dealer gave me when I bought it (tires only had 5000 miles left on them then)So, as you can see, I spent less than even if I owned a Lexus instead, and probably less than all these poor devils here that brag about their alleged low cost Datsun-Mitsus and Hyundai-Kias.And that's THETRUTHABOUTCARS. My Cars,
  • NJRide These are the Q1 Luxury division salesAudi 44,226Acura 30,373BMW 84,475Genesis 14,777Mercedes 66,000Lexus 78,471Infiniti 13,904Volvo 30,000*Tesla (maybe not luxury but relevant): 125,000?Lincoln 24,894Cadillac 35,451So Cadillac is now stuck as a second-tier player with names like Volvo. Even German 3rd wheel Audi is outselling them. Where to gain sales?Surprisingly a decline of Tesla could boost Cadillac EVs. Tesla sort of is now in the old Buick-Mercury upper middle of the market. If lets say the market stays the same, but another 15-20% leave Tesla I could see some going for a Caddy EV or hybrid, but is the division ready to meet them?In terms of the mainstream luxury brands, Lexus is probably a better benchmark than BMW. Lexus is basically doing a modern interpretation of what Cadillac/upscale Olds/Buick used to completely dominate. But Lexus' only downfall is the lack of emotion, something Cadillac at least used to be good at. The Escalade still has far more styling and brand ID than most of Lexus. So match Lexus' quality but out-do them on comfort and styling. Yes a lot of Lexus buyers may be Toyota or import loyal but there are a lot who are former GM buyers who would "come home" for a better product.In fact, that by and large is the Big 3's problem. In the 80s and 90s they would try to win back "import intenders" and this at least slowed the market share erosion. I feel like around 2000 they gave this up and resorted to a ton of gimmicks before the bankruptcies. So they have dropped from 66% to 37% of the market in a quarter century. Sure they have scaled down their presence and for the last 14 years preserved profit. But in the largest, most prosperous market in the world they are not leading. I mean who would think the Koreans could take almost 10% of the market? But they did because they built and structured products people wanted. (I also think the excess reliance on overseas assembly by the Big 3 hurts them vs more import brands building in US). But the domestics should really be at 60% of their home market and the fact that they are not speaks volumes. Cadillac should not be losing 2-1 to Lexus and BMW.
  • Tassos Not my favorite Eldorados. Too much cowbell (fins), the gauges look poor for such an expensive car, the interior has too many shiny bits but does not scream "flagship luxury", and the white on red leather or whatever is rather loud for this car, while it might work in a Corvette. But do not despair, a couple more years and the exterior designs (at least) will sober up, the cowbells will be more discreet and the long, low and wide 60s designs are not far away. If only the interiors would be fit for the price point, and especially a few acres of real wood that also looked real.
