Here are consistancies that I keep seeing between all of these cars, along with my analogy as to why none of it works;
First, I would like to add that function is more important than fashion when modifying any car. When manufacturers hire design team members, they go through years of schooling to get there and generally speaking, they know what they are doing and more importantly, why. Keep that in mind when considering the following.
- headlight and taillight units from other makes/ models:
When you use a light fixture from another vehicle, although the part may look good on the original make/ model, does not mean it fits in with any other car. That doesn't mean it can't be done tastefully. It just means that you should have some level of education on the subject before attempting it yourself.
The 300zx headlights, beamer grilles and Accord taillights on the blue car towards the beginning are a perfect example of that.
I think that you can tastefully have exposed headlights on an MKIII, but you should be sure that the units used match other body lines. The 300zx lights look good, except that they do not match the curvature of the fender, hood or bumper in the slightest.
- vents of all shapes and sizes:
Don't bother with anything other than ducting for an IC and intake air. Nothing screams idiot on a car louder than disfunctional vents. I also have a peave with different shapes of vents on a car. If you want to go with naca, stick with naca ducts everywhere,etc and only do it where you NEED it.
- aircraft landing gear spoilers (on some):
As much as you'd like your car to feel like a racecar, you will NEVER see the likes of speed needed to make an abomination like that functional. If and when you do, you'd better hope that your tires and suspension are up to par as well as the rest of the aerodynamics on the vehicle, and the spoiler had better be fastened and braced to something a hell of a lot stronger than your deck lid sheetmetal. I won't even go into rear spoilers on a FWD car.
- wheels from other makes/ models:
Most importantly, these wheels, weather they were farmed out by another manufacturer, such as enkei, kelsey hayes, etc. or made by the manufacturer of the car they are intended for, they were designed to take the loads of that car's weight, suspension and body roll. Any time you change your wheels without researching the load capacities of the lug shoulders, rims, centers, backspacing, etc. you run the risk of damaging a wheel and consiquently, whatever else it takes it's toll on.
How a wheel looks should be secondary to functionality, in my opinion.
- wide body kits:
These can look fucking gorgeous on an MKIII if done tastefully. If you look at the body lines on an MKIII, they have a bit of a coke bottle shape in them that can be accentuated. wheel flare type kits to accomodate bigger wheels and tires look good too, but they should look symetrical, front to rear.
Just keep in mind that you should moderate how wide you go. Anymore than 2" looks like crap unless you have the mechanical reasoning to necessitate it.
Remember that the designers that made these cars did have clean lines in mind. Redundancy of body lines and very radiused curves do not look right on these cars. They don't have as many curves as an MKIV and that should be taken into consideration when putting anything on these cars.
- paint colors, and/ or schemes that question if there are only three primary colors in a prism color wheel in this universe:
We understand that you want to stand out from the crowd, but you don't need to make it painfully obvious. There are a lot of very tasteful muted colors that look excellent on just about any car. That's not to say that bright colors have no place. Just be sure that if you go with a bright color, understand that it accentuates everything on the car and you might want to tone down any custom work you do on the body of the car. If you are going with a high chroma color, that should be the focal point of the body.
I am a fan of more muted colors on more custom bodywork with any car. Keep it respectful and no matter what you decide to do with the body, do the craftsmanship right.
- exhaust shop pig tubes:
Exhaust is fun. It's always been one of the focal points of any fast car for obvious reasons, but again, can become extremely distasteful quite quickly if overdone in the wrong manner.
I have seen multiple outlet exhaust that looks right on certain cars, but anymore than two tips on an MKIII looks hideous.
Side pipes are a very gray area on these cars. You have to understand that they are somewhat redundant and disfunctional, because of the single exhaust bank of the I6 configuration of the engine. The best exhaust systems for these engines is a large, single exhaust that creates the least amount of turbulence, so if you are willing to sacrifice some function for fashion and go with side pipes, just know this.
Aside from that, again, these cars do not have a lot of curves in them. They pertain to straight lines and slight curves more than anything else, so because of the curved nature of a side pipe, they can look wrong very easily. Yes, other sports cars have them, such as the AC and Shelby Cobra, some Corvettes and some Vipers. They look tasteful on those cars, because they have the curves in their bodies to support a curvey exhaust.
I think the only way a side pipe looks respectful on these cars is if they are rather understated and have rectangular tips.
I actually don't mind seeing a channeled exhaust outlet in a rocker panel on one side, for the sake of functionality, but I still think that a rectangular tip should be used.
I have considered going with custom taillights and even thought about going with fixed, exposed headlights, but if I did that, those would be about the only major changes made in the car and I would have to be careful about what I selected as a replacement.
I don't mean to offend anyone, but rather shed a different light on the subject to help people understand why most of these cars are being seen as a bit of an eyesore.
