Opinions on IASCA "Stock" category

riadb · Postby **riadb** » October 15th, 2008, 10:06 am

With respect to IASCA "stock" division, why are sedans and hatchbacks/wagons in the same category?

It is plain and obvious that with respect to the vehicular requrements outlined in the rulebook, wagons/hatchbacks have a clean cut advantage over sedans.

In a sedan it is required that our enclosures be located in the trunk/cargo area and all seats,etc be in the upright and locked position.
As a result the subwoofers are basically concealed in the trunk behind the back seat and are not able to directly couple with the air in the cabin area. Scores are on average are much lower because the rear seat backrest impedes the oncoming sound wave.

In a wagon, things are different. Remaining "stock" with the enclosure located in the cargo area, the subwoofers are still able to directly couple with the air in the cabin area. This provides the ultimate scenario for
"stock" competition as there is nothing impeding the sound wave resulting in higher scores when compared to a sedan with the same equipment.

now honestly I wouldn't sell my sedan and buy a wagon for IDBL. It just isn't feasible to me.

A fair adjustment to the rules would be to put 2 categories:

1. wagon/hatch vs wagon/hatch
2. sedan vs sedan

here all competitiors would be on the same level playing field with respect to "vehicles" and i'm sure more people would come out to compete without the fear of being eaten up by the SPL wagons..

now i am not contradicting the rules here....just looking for opinions on the situation from fellow competitiors.

seats can be dropped for spl competitions in sedans that are in stocn categories

markzz · Postby **markzz** » October 15th, 2008, 12:15 pm

really? but only for vehicles which have manufacturer set folding seats.. and not those where the seats were not originally intended to be folded. correct?

so say a vehicle with non folding seats where i removed the pair of lower bolts enabling it to fold?

this rule kinda makes little sense to me... seems the rules are giving some vehicles an unfair advantage over others.. if i did fold my "non stock folding" seats.. wouldnt that make the competition fair?

Only if the Seats can do so by OEM specifications. you can't unbolt stuff etc.

It must be able to fold up and down seamlessly as the Manuf. intended.

Dont be afraid of havin your backseat up, just try to work on your enclosure design

instead of fighting the rules, make a spl box for spl
people use music boxes and want to know why they dont score high spl
your box is quicker changed than the rules

so hear this...... if u fold down the hand rest in the B15 and Almera and them, would you get a higher score. and then too would you be placed in a higher category?
