I have a concern with using a laser level to decide if an enclosure is to high. I don't feel this will work because many vehicles are not parrallel to the ground.
Example:
Competitor A: Has a vehicle that is lower in the rear due to the weight of his equipment. Thus, safe drivability of this vehicle is diminished greatly.
Competitor B: Has same vehicle as competitor A with exact same equipment and enclosure in rear, but has built up suspension in rear to allow for better and safer drivability. However, competitor B will not be able to pass a laser level test because the rear of his vehicle is higher than the front.
This is a perfect example of a competitor getting penalized as a result of creating a street drivable competition vehicle. I personally feel that using a laser level is not the answer, unless you can figure out a way to get it to work in these types of situations.
Sincerely,
Jason Meyer

There is a way to use a lazer light, to determine compliance with the rules.
Has anyone asked Mr. Harris about his intentions of using a lazer for dB Drag Racing? With his crative mind, it is not unlikely that he has already developed a way to use a lazer in a manner that would be beneficial to dB Drag Racing.

if the lazer level utilizes a glass bubble to level it then this leaves the measurement up to human error. A lazer level would have to be self leveling. These cost upwards of $150 and can be found at most lowes or home depots.

To reduce human error, do not use a bubble level to determine accuracy. Also, self leveling units do not compensate for changes in elevation.

So your saying level is different per your altitude?

Yes, as it relates to the plumb. Please review Mr. Meyer's post (above), for an example of how elevation could negatively effect the self leveling type of lazers.

Perhaps the rules should say, that if it fits below the stock parcel shelf, it should be legal... IMO its stupid to limit boxheight, by the frontdoor windowline Side Window Line post

I haven't seen that type of level in Europe. Does it cost more here?
Which instalers are building boxes for customers to fit side window rule or they just go to use most of the trunk.
What tyre pressure gauge is best to have if it is not alowed to deflate tires?
How can we know if rear springs are stock?
Or should we alow full trunk to be used.

I really don't see why this rule isn't discussed more. Alot of other rules are just small changes that are discussed ALOT. This rule is obvious WEIRD, and not alot of people care...
Please... A new rule is the only way to go, i think!

When the box is in a trunk, not the cargo area of an suv or hatchback, it is allowed to be over the window line.

Johny: I know about trunk cars, but many people here have problems with that rule and can't use full trunk in HB or SW cars.
Carsten: how many average competitors from Europe post in this forum? Only few...

i think the level should be determined were ever the box is located. in other words. if the box is in the back of the car. then that is where the hieght test should be preformed. not like what i seen at finals. with the line test being done in the front of the car to determine if the box in the back of the car will pass or not.

You cant make a universal height, it would give too many cars an unfair advantage, and too many others would lose out on a lot. We just need to come up with a better way to measure the current rule.

99.9%of the guys in the world use a stock parcel shelf to limit the height of the box in car, why do we not do the same, it is after all these guys that we want to compete, no parcel shelf means a wall test, but otherwiswe it will take out of this the deciding factor of human eyes for most cars and stop the average joe being put into sm 1-2 cos there box is under shelf but too high for street!
this makes sense to me! and before anyone says it will affect some cars more than others, yes, but the cars it will help are the street cars that we need for this sport to grow - period!

I don't understand what is wrong with this rule, would anyone care to explain why it is a bad rule?

SUV's do not have a parcel shelf. There are several other vehicles that do not have a parcel shelf. The current rule is fine and easy to understand.

This rule is bad. It prohibits people to use trunk as it was designed from factory. That is up to the stock self.
