Lead on LR tube

They may spend millions, but those are still street stock suspensions.

I'm telling you, boys, this is all going the wrong direction and it's going there fast! We've had rules for years to limit how light we could make things and now that somebody has figured out a little trick (AKA, understanding the laws of physics), we're going to end up with rules on how heavy we can make things. The box is getting smaller every year. This is turning into NASCAR right before our eyes and it's a matter of time before we're just told "here are the rear end components you can use and here are the two places (which we own both) you can go to buy them".

While your point is completely valid, and now is the time to address the rules issue, I will give you a little hope and let you know dirt racing is way way way better off than NASCAR. And I think you know where I work. We spend upwards of 3 hours in pre-race tech every week. The amount of pre and post race tech that dirt racing has is amazing compared to NASCAR. NASCAR confiscates three cars every race and takes them back to their headquarters and takes them down to chassis. I think where the rules were at last year were a good place, and they should only do stuff for safety now. Which I think is why they are considering the lead on suspension components. That unsprung weight acting on the housing is just asking to break a tube and send the tire, wheel and tube flying, which poses a safety risk.

The rules from 2014 are plenty good enough. They just need enforced. The current rulebook requires nearly Nascar level inspection to be enforced properly. I have good reason to believe the inspection process is going to steadily increase in length.

Dustin, it is good hearing from you and you are certainly in a position to share some real world experience of what the "next level" looks like.
In dirt racing, I think we are really dealing with a few different issues here that are compounding into a larger complex problem:
1) People that don't know anything about race cars are policing the competition of said machines.
2) They already don't enforce the rules that they have yet they keep adding more.
3) Many rules that are created in an attempt to save racers money do just the opposite.

Aint it funny.....NASCAR hires ex-cheating crew chiefs to be inspectors. Dirt series hires joe blow off the street! smh

[TALON75]

Lucas's new tech is no joe blow off the street.

Lucas's new tech is no joe blow off the street.

correct, he will straighten (not a nice word)(not a nice word)(not a nice word)(not a nice word) out.

Wasn't sure it was released yet, as I never looked.

Just to update, someone I know talked with the new Lucas tech guy and he said they were going to be weighing rearends in Georgia and Florida

[toyracer]

Drop Shock. Do you know what they are saying the weight should be or is there a minimum/maximum rule?

Just curious

[Drop Shock]

The way I understand it they are going to be talking with each chassis manufacturer and the rearend can't be a certain amount more than how they're sold from the manufacturer. Sounds a little weird since some of the builders (Bloomquist and Richards) are thought to have started this trend

So, Bloomer can say what his is allowed to weigh? Lol

This was the original plan but has changed thus the hold up on rules, They were indeed going to weight the whole hanging weight of the rear end via something along the lines of something similar to a hanging fishing scale from the chassis to the rear end on both sides. The number that was talked about was 280# (have to assume they were talking with wheels and tires also). However the problem I see with this is this (#1) and they should have done it this way IMO (#2)

#1 There no left to right weight just a total, that means you could run the lightest most exotic rear end to get the total weight down and then pile it on the left side. Or make the right side, center section, ring gear, and spool as light as possible to move that weight to the left side and still be at the minimal total weight. This may stop some of it, but not fully to those that can afford to spend a ton of extra money to use really light stuff and replace it all the time because it may not hold up for long.

#2 My idea is to simply jack car up unhook rear shocks and set the tires down on 2 scale pads and weigh the whole hanging weight of the rear end. Then settle on some total number for the rear end or a number for each side. You could go like 280# but with only half or 60% on the left side. Just have to pick a number and go with it, as it shouldn't be that hard to get a average and that way everyone knows where they stand. This way is simple and don't take long to check and is likely the fairest way you going to find and the easiest to tech with the least amount of time.

I don't think the rules are in print yet, so I won't post them but you will laugh when you see them. Least this 4th or 5th version is somewhat simpler then the other versions you have to wonder about them anyways. What’s crazy is you won’t be allowed to bolt weight on the rear end (cheap and still not legal with a manufactured clamp like Kyser’s) but you can spend whatever they want for a really heavy cage and be legal, lol.

Easier way, ultra sonic tester call a max tube thickness, and a spring loaded punch.
