Is there a reason why you would want to mount to the frame and not just have a mount in the bed itself? Remember, you get points for having a spare tire mount.

I wanted to mount it low as possible as well as utilize the tire mount I would fab into the frame as part of rear shock mount under the bed. ..that is as long as I don't get docked for cutting a big hole back there...

Morning guys. I'm in the midst of getting things together to fab a class3 rig and have a couple of questions for the experts:

1) I understand that I need to have chassis rails if I choose to go with a tube chassis. If I read the rules correctly they need to be the same length as the wheelbase correct? If I decided on a 12.3" wheelbase than the chassis rails must be the same length? Seeing how I'm kinda asking - what is the max wheelbase that can be run?

And B) could I theoretically have both rear steer and a dig in the same rig ? I understand I can only use 1 at a specific course but if the other was clearly locked out it would still be a legal rig correct?

Appreciate any help and happy holidays!!!

1- You do not need chassis rails in Class3 if you build a tuber. The rig can be all tube.
If your WB is 12.3 then your chassis length will have to be 12.3 or more - No max WB. Build as you see fit but remember your gate min widths.

2- You can have both - just like you said, only allowed to use 1 on a course. Most just pick 1 or the other to make it easier.

Hope that helps!

Thanx doublej!

I'm still in need of clarification on scale points per course. If I have -60 in scale points does that mean for each 10 gate course I get -30 added to my total score?

Thanks for your time guys!

Number of gates is up to the event organizer. But if you have -60 scale points then yes you get -30 scale points or 50% of your scale points per course.

2.2 Flatiron question.
The tires are marked 4.84". Most web pages that sell them list them at
120mm (4.72"). Unmounted they measure just over 4.25". Mounted on my
Integy beadlocks they measure 4.5".

Legal for class 2? If not, why?

Tire size will be determined by advertised manufacturer specs (tires without available specs will be measured off the truck as mounted on the wheel laid flat).

So we would go off the specs from Pro-line at:
Height: 4.84" (123mm)

Class2 tires limit is:

120mm / 4.75" max tire size with a 2.2 max rim size including spare.

So no sir, not class2 legal because someone decided to list their tires bigger than they actually are.
The reason for using manufacturer specs is to make life easy on the Tech table guys and to keep things simple. Tires can change size a lot from setup to setup, going off specs means you have a set number. Unfortunately there is a tire or two out there that could use their specs updated, it has happened before - Why Pro-line hasn't updated these I have no idea.

I know the rule. I was on the SORRCA committee.
However, the tires are mis-marked and the community knows it.

This needs to be addressed. Hopefully a vote can be taken for an amendment.

Thanks.

We have gone over this time and time again but I will bring it up again.
The manufacturers need to fix their listings. They have before.....

Hi Keven. Still trying to stir the pot huh? Hope you are doing well. Feel free to stop by a comp some day!

[KevenP]

Thanks.

I would think it would be easier for a committee to make an amendment rather than ask a company to change their mold.

[doublej]

You have already proven the mild isn't the issue. If they fix the mold to match the specs then the tire would be bigger.....

[War Pig]

Keven, there are so many options now that 2.2 Flatirons aren't even on the radar. The rule about manufacturer listed size will remain. We don't make amendments for individual instances like this. If we did, there would be dozens of amendments that would just confuse people. Thanks for the input though!

[KevenP]

No, I meant change the numbers on the mold to reflect the actual size. Sorry.

[KevenP]

Thanks Tim,
I figured if I posted pics and gave facts there might be a vote for an amendment. Not just a 'no, because we said so'.

The only other tire that I know of having problems with 'stated size' is the Proline TSL?

What about wheelbase for a class2? My thought is if I can pull it off I may do a hybrid that with minimal changes could run either class

[doublej]

There is not a wheel base restriction in any class. Only body restriction that go off your wheel base.
As long as you meet that as needed, your fine.
