Lead on LR tube

[jr dirt]

It is illegal if it is bolted on. It is not if it is slide onto axle tube. There are companies now making l/r axle tubes out of tungsten for the very affordable price of $6k. It frees the car up on entry & gives a ton of drive off

[sidewinder69]

How does it accomplish that jr dirt?

How does it accomplish that jr dirt?

Because that is what more lr weight does.

[sidewinder69]

whats difference in doing that vs putting a piece of lead directly above it on chassis. thats the theory im looking for

[zeroracing]

You don't have to pick it up on the bars, lower so less will transfer through cornering.

[Flyin Iowan]

i believe its novembers issue

[jr dirt]

When the weight is directly on the axle, the weight is not transferred through the bars, springs, shocks, body roll etc... like it is when its mounted above the suspension. So if you have the weight on the axle (not bolted to the bird cage), when you accelerate from center off, you have instant load (traction) on the l/r &don't have to wait for weight transfer to the l/r through body roll, shocks, springs, bars etc...

So for years and years they've been making the rears lighter, but now the hot tip is to bolt weight right to the tube? Why not just run steel axle tubes? They're cheaper. From what I'm reading on DoD the next meeting will determine weight on suspension parts legality, add to that what your allowed to have your rear made from. I guess now they're gonna make everyone run magnesium rears with titanium axles, Titanium bird cages and maybe carbon fiber brakes in order to save us money... I wish they'd stop with all this legislation I can't afford for them to save me anymore money.

I know many think this is all new but it's not, it's been going on for least 2 years by some and probably longer. It's just got taken to an extreme by many that it's become more visible and has slowly gotten out.

That being said: The part where they are going to discuss this on rules: "the Council will meet at PRI in December to address weighted suspension components, rear end construction materials and axels."

This can be interpreted in several ways, first is they are going to try to stop unnecessary weight on the rear end which is going to be pretty difficult and/or the second is making exotic material illegal. I feel they are talking about the exotic material like tungsten and possibly just out outlawing titanium just for cost reasons. Just think what could happen when a certain someone's 50# wheel Spacer breaks off the axle snout and sends a 100+# wheel/tire/hub combo into the stands, that thing won't stop for 2 miles!!!

They can't or won't enforce that the bodies have to be straight (1" tolerance), so sure make a ton of more rules no one will enforce or check after the first race with the new rules. However there are things happening that are not very safe and does need to be addressed. Nothing wrong with some of these things but they need to be done correctly so it's safe for the other drivers, crews and fans.

Are they really putting weighted wheel covers on? That is dangerous... Weight on the tube I get(No Biggie), kinda surprised it took this long to become popular. If they're getting rid of exotic materials that's fine, but your right its just something else they won't tech. Speaking of body rules, you ever notice bloomer's car always becomes dished on the RS once they start racing.

Have a good day, Billett.

weighted wheel

Are they really putting weighted wheel spacers on? If so, that's just stupid, the rotating mass would be insane. Just build a weaker engine if its spooling up to quick for ya.

yes LR wheel spacers that are made of heavy Mallory material
helps slow down the zing of the motor and helps from chattering tires on entry and keeps things momentiumed up.

speed/traction or safety.
fine line I guess

I'm not gonna put others at risk with something like a weighted wheel cover. The wheel spacer is smart and to me a non-issue. I love innovation, trying new things, going in a different direction, but I won't risk you or anybody else getting hurt on something so stupid and senseless.

[Matt49]

I'm not gonna put others at risk with something like that, I'll just think harder and look for a solution that's less likely to kill or seriously injure someone. Seems like building for less power would make the most sense from an economic/performance standpoint. If you can't use it its wasted money, but I guess I'm crazy to think that way. I love innovation, trying new things, going in a different direction, but I won't risk you or anybody else getting hurt on something so stupid and senseless.

At the national/touring level, I think the challenge with just building for less power is that you need 900+ in qualifying but only need 400 at some places by feature time. A good driver can tame a big motor when it gets slick. But if it's WTFO track conditions and you don't have it, you just don't have it.

Steel Axle tubes, and steel birdcages, how much added weight would that be?

I suppose you could line the inside of a steel tube with a smaller tube, and pour lead between, that would be an idea. Say fill in a 1/4" gap with led?

I have always wondered about this, adding to the LR axle, wieght but have never tried it.
