Up until recently I have never really cared about the Car Show part of our "Sport" but my dad purchased a 96 Impala SS that almost fits in the Stock class. I've got questions about the allowable modificiations that have already been done to it from general maintenance and what we can do to get it back to "Stock" for the shows.
Visual Modification Classes
There will be four (4) visual modification classes. These classes are based on the number of visual modifications that have been made to an otherwise GM Factory Stock B-body Vehicle. It is important to note that 1-color window tint will not be considered a modification in any class. The visual modifications allowed per class and the respective description is as follows:
· Stock 0 modifications
Please note that if you are uncertain about any modification that you have made, plan to make or was made prior to your ownership, please consult the National Car Show Judge before the show for clarification.
Stock is defined as the way the vehicle was shipped from the factory. Any visible modification will place the vehicle into the next higher modification class. (Examples: Red Bow Tie, Cross Flags, CD Changer, etc.) There are several EXCEPTIONS as follows:
1. Tires Since BFG has discontinued the OE Comp-TAs in P255/50ZR-17 size; you will be allowed to replace them with any brand you choose. However, they must be in the factory P255/50ZR-17 size and speed rating.
Are V-rated tires still considered Z-rated?
2. Exhaust Due to the age of these vehicles, many may have needed a new exhaust system. Any muffler may be used as long as the factory size exhaust tubing remains. Resonators must still be intact. No muffler deletes, catalytic converter deletes and no H or X pipes allowed.
That's cool, but he's got the stock exhaust up to the exhaust tips. What do we need to do to get this back to stock? I have an extra set of factory tips, but they are not in good condition. Will we have problems with straightning them and refinishing them?
3. Windshields Must be to GM factory specifications for year of vehicle (e.g. no Sungate windshields allowed prior to 1995.)
If the car originally came with a Sungate and that had to be replaced with a non-Sungate windshield due to availability and/or price, will there be any problems?
4. Windshield Wipers These must be factory stock or OEM replacements. No 9C1 style allowed.
The paint on his car's windshield wiper arms is chipping. I've noticed that on several other B-bodies, including my own. If we strip that and repaint or powdercoat in black, will we have any problems?
5. Batteries Any battery is allowed as long as it is in the GM factory location.
Does it matter if it is side post AND top post? I'm guessing not.
6. Spare Tire Factory Spare Tire and Rim P215/75R-15. Spare tire must be in factory location. The factory spare tire cover will be removed at judging time to verify the correct spare tire and rim are present.
Will there be any problems if the factory tire has been used or if it was replaced with another tire of the same size and speed&load rated?
7. Factory Side Scripts Must be in place and of GM factory body color.
ok, are these still available from GM? If not, what do we do? Would sidescripts from MBA in black (for a black car) work?
8. Spark Plug Wires Must be GM Factory wires and OEM replacements. No colored aftermarket wires.
The Factory wires are VERY GOOD. Other than having to repair 1 wire, the ones in my car have been good up until recently. I'm at 145k miles.
9. Floor mats Must be GM factory mats with snap on front mats. These will be checked at judging time. No carpet changes allowed.
I question the carpet change rule. As these cars age, the carpet wears in the ones that actually get driven. It's a wear item. New carpet is no longer available from GM. Tom Frederico stepped up a few years ago to offer a factory quality or better quality carpet for us. I question why we should be punished with replacing a wear item with his carpet if we stay with the same OEM color?
10. Headlight Bulbs Must be GM factory bulbs or OEM replacements. No hyper-whites, blue-ions or HID replacements or T-84s allowed. These will be turned on at judging time.
What about alterations to the headlight's wiring harness to fix what GM cheaped out on? And of course, in the case of export cars, if a car did in fact have the T84s installed from the factory, then it shouldn't be punished, right?
11. Shocks GM factory shocks or OEM replacement shocks that have the same characteristics as the GM factory shock are permitted.
Shocks are also a wear item. If somebody goes to their local parts store and buys lower cost shocks, should they be punished?
Here are some examples of visible modifications (note that this list is not all inclusive): Bowtie (colored or illuminated), cross flags, any aftermarket emblems, side script or body side molding delete or change, tires other than stock size, wheels other than stock size and finish, headers or any aftermarket exhaust, any SEO
or 9C1 additions to a Impala SS or any Impala SS additions to a Caprice or 9C1, aftermarket carpet and/or floor mats, non-OEM brake calipers and/or rotors (painted or not), suspension modifications, stereo systems, smooth bumper covers, aftermarket spoiler, aftermarket or custom hood or custom seats, aftermarket chrome, billet, anodized, or polished aluminum pieces, vinyl tape, decals, stripes, simple vinyl or painted on pinstripes up to Ό in height with plain ends.
I also have a question about the wheels. Naturally these get the occasional curb rash. If we go far enough to strip the clear coat, smooth out the damage, then re-clear the wheels, will we have any problems with judging?
Does polishing a stock metal part hurt with the points?
Another wear item is the rotors. When these need to be replaced, what do we have to do to keep them "stock"? As long as they are the factory size and have the hats painted black for impalas, they are legal, right?
