Definitions of "Stock"
I just thought it might be fun to start a friendly debate on what peoples different opinions of a "Stock" car are and what their reasoning is. Now I know some people are very passionate about this so let's try to keep it fun and not make anything personal!
I'm personally kind of on the fence on a few things. I think things like air filters that would be replaced due to maintenance anyhow do not void a car of it's "Stock" classification. So here is a short list of parts that I feel can be "replaced" and still allow the car to remain classified as "stock"
1. Air filters (filter only, not an entire CAI kit).
2. Tires - as long as they mount onto the wheels that came with the car.
3. Plug wires - they would be replaced later due to maintenance anyhow.
4. Spark Plugs - again a maintenance item.
5. Fluids - Engine oil, Transmission fluid, brake fluid, differential fluid, etc...
6. Brake Pads - as long as they fit into the OEM calipers
7. Brake Rotors - again as long as they are designed as a direct replacement with no other supporting modifications required.
8. Muffler(s) - muffler only, not the entire CAT back.
9. Battery(ies) - as long as it's designed as a direct replacement in the stock location.
10. One I'm on the fence with is Tuning. On one hand I feel that tuning only maximizes the "stock" potential of the engine since OEM's need to worry about warranties and are therefore going to be a little more conservative in their tunes. But I can see the other side of the coin too where some people feel that a tune disqualifies a car as "Stock".
So let's hear what some other peoples ideas are.
