Lead on LR tube

[slide-skill]

cup has a rule on this, they caught guys lining the tubes with tungsten,this is an old asphalt trick

Whoops , I thought everybody had forgotten that trick ! Daytona 2001

Anyone remember the steel tube protectors made by Coleman a few years ago?

Anyone looking for tungsten i have some 2 5/8" X 3 5/8" X 6" 36lb blocks for $1200 a piece ... they retail for $1800 text 7047465255

The unified rules committee is as much Lucas as it is WRG if not more. Remember Lucas is the group that led the suspension rules last year and Lucas is who is leading the is current deal. WRG doesn't really have a spine and they are along for the ride to do whatever Lucas wants.

Lucas screwed it up and WRG mostly went along. They are not the same entity.

That's pretty much what I meant. That was the simple way to put it.

[calverton]

its not just wrg or lucas thats's in this game ,The Council’s sanctioning body committee met in October to develop unified specifications for all Council members, including the World of Outlaws, Lucas Oil Late Model Dirt Series, MLRA, Ultimate Series, Southern Nationals Series, ALMS, MARS, DIRTcar Racing and Eldora Speedway. All dirt late model sanctioning series will be encouraged to adopt the specifications effective January 1, 2017.

"Tungsten on LR axle tube" - I have some for sale its 2 5/8"X 3 5/8" X 6" and is 36lbs ... $1200 a piece it retails for over $1800 text 7047465255

I think this guy is trying to recover his investment ahead of a rule change...

Is the added weight only beneficial if it is on the left? Are there any benefits, or side effects, from adding weight to the right as well?

[RCJ]

The formula for weight transfer is (Total weight X g force X c/g height) divided by track width.I know weight transfer is a moving target and some chicken or the egg type problems but it doesn't make provision for unsprung or sprung.In my experiences lower unsprung is better.I do wonder, from the work Bloomer has done with Penski, are they trying to change the natural frequencies?

This is exactly what I was thinking. With the insane amount of compression dampening being run in the LR, we probably need MORE sprung mass to achieve critical dampening. The LR being TOO stiff is causing the car to "bounce" on the LR and not providing consistent traction at the contact patch.
There's another solution to this problem (if in fact it is the problem) but that would not be legal under the "unified" rules.

Penske has an illegal solution.

Penske has an illegal solution.

Yes, they do...

[7uptruckracer]

Yes, they do...

Are we taking to shocked spring bar or inerter shock or fric shock lol

Would a thick steel tube get the job done? Say 3/8 or even 1/2 thick?

[JustAddDirt]

Steel tubes on a mod quickchange are 1/4-5/16" thick
I am figuring if you ordered a steel tube for a LM QC it would be the same
