i completely agree, matt, and well put. your a premier driver and many of these issues are more obvious to you than an old "back marker" like myself. given the correct tools and gauges, tech inspection should be able to ferret out any body issues right at the get-go.  years ago when tri-oval racing with 4.5 stockcars one intrepid driver had mounted his body angled so far to the inside to try and gain a weight/handling advantage that you couldnt pass him on the inside - you would make contact with his upper body/roofline. its competitive racing and most guys will start out with a tech spec car then "massage" it a bit for an edge. somethings work most others do not. one time i painted the ends of my 16d magnets zombie green to see if anyone noticed. it didnt help my driving but others thought the car went faster, myself included. thank you for your time and responses. best of luck with managing this issue.

[Matt Bruce]

Im not the one managing it, Im the bad guy apparently for bringing it up. Thats fine with me. All of these ridiculous reasons to not measure the body thickness lol, has actually been quite amusing, and makes it even more obvious once you connect the dots. Ive seen the comments on Facebook about adding more paint, blah blah blah, which just confirms there are bodies that are pulled thin in peoples possession. I dont need convincing, Ive seen it for the past few years, in many forms. If the IRRA wants to fix it, they will give us some measuring parameters soon, and for Gods sake enforce them. It has been quite some time since this was brought up, and the fact there has been No response from the BoD should make everyone realize the problem is deeper and more complicated than what you might think. At this point, its gone unchecked for so long, that just adding something as simple as a thickness measurement has implications for a lot of people. Bottom line is, participation will continue to drop if rules arent being implemented and followed.

If racers see others having an unfair advantage over them. They will stop racing!!!

We are close to an announcing a updated Stock Car body rule. Stay tuned...

[B.C.]

Do away with the roof altogether. Start running convertibles like NASCAR ran in the late '50s.

[Tom Thumb Hobbies]

Some are so thin they might as well be convertibles.

[IRRA Retro Racing]

As point of clarification in the Stock Cars rules....

 

Section E BODY, Para. 2b should read...

 

2b. Bodies cannot be trimmed above the lower door lines. The area to the rear of the rear wheel well shall be trimmed in a single straight line extending from the lower rear edge of the rear wheel opening rearward to the lower rear edge of the body (I.e. rear bumper). The lower rear edge of the body shall be horizontally even with the centerline of the rear axle.

[Eddie Fleming]

I must be mounting my stock car bodies to low by using the molded in cut line. The rear bumper on my cars is well below the center line of the axle. 

 

Honest question should I raise the rear of the body or should I cut into what I call the taillights?

[Alan Draht]

Photos, people!!  Photos, please.

[Jay Guard]

Eddie:

It probably would be best, and better looking, to raise the rear of the body a bit.  I'm surprised that if you're really cutting into the actual tail lights, and not just a bit of the bumper, that the tires don't rub with the body mounted that low. 

[Jay Guard]

Photos, people!!  Photos, please.

Alan:

This is approximately what we are talking about with the new rule.

In this picture the bottom edge of the rear bumper at the extreme rear of the car is still just a bit low, but it should give you the idea of what the new rule requires.  Another way of looking at it is that the rear most edge of the body should be at .405" which is where the centerline of the rear axle is.  This rule precludes someone cutting out the entire rear of the car and also not cutting the rear out at all.

[Eddie Fleming]

Ok Jay that answers my question. Ignore the cut line and raise the back to At least .405. And cut straight across. 

 

Just for reference a quick snap of a Kelly body cut on the cut line (you can still see the line a little)

This is watt I come up with. Its a RF Charger with the black line at .405 ish.

So no more rear bumper is ok?

Eddie:

You wouldn't have to cut straight across as the cut could angle down towards the front of the car (as in the pictures above) but yes, the extreme rear does have to be at the same level as the axle centerline at .405" high.

[Jay Guard]

Tom:

Yes that looks correct.

[DE38]

I think I might have screwed this one up trying to trim for this new rule, the rear behind the wheels are maybe too high.

Charlie the way I read the rules the way you cut it is correct but I think is is not. Very vague still. Pictures are necessary to clarify. Has anything changed?

[Jay Guard]

Charles:

What you've got there is perfectly fine, in fact I think it looks cool.  It appears that the rear-most part of the car/bumper is right at the centerline of the axle (i.e. .405") and the way it's cut right behind the rear wheel is also fine.

[Jay Guard]

Hey Mike:

What do you mean by "is is not"?  But as you said and from what I can see Charles' body is just fine, in fact it's practically the poster child for the new rule.

However I will post an "official" picture which should (hopefully) make the new rule perfectly clear in a few days.

[DE38]

Ok, cool, but just in case I get bounced Sat by Noose I will direct him to this post.

[Eddie Fleming]

Looking at post 113 and possibly 116 it looks like the rear bumper is not required?

 

But post 107 with the original clarification seems to require the bumper?

 

I am not trying to make trouble I am just looking for clarity. 

[Jay Guard]

Eddie:

That is pretty much correct.  If you look at the way the rule was written in the first of the the year (2024) revision the cut behind the wheel would have been horizontal at .405" and looked kind of weird.  This new revision allows some material right behind the wheel then angling upwards/rearwards to the height of the axle centerline.  Whether there is any actual rear bumper left is really determined by how low the body is mounted.

[DE38]

The way mine ended up is just under the lights,no rear bumper is left.I cut this one right on the cut line.

[Eddie Fleming]

So this would now be a legal body?

 

it is .405 from the block to the bottom of the rear, and it is trimmed on the cut line.

Folks if you  follow the trim line you are fine.
