Agreed I just want to see what he comes up with.

 

That all really depends on how your car is. If it was a RWD it would need a rear spoiler to push down the back wheels with downforce to produce more power. My car is FWD so the power is in the front wheels. The downforce created by the splitter will put force into it creating more power and better turning. It really just depends. Also the rear spoiler on my car helps even it out more with equal pressure. Right now the spoiler is more of the back and less force on the front wheels, thats why it should be better.

 

More downforce doesn't equal more horespower, it just helps with grip at high speeds. No offence, but at the speeds we drive you're going to see very negligible benefits from a splitter. If you're doing it for looks, best of luck then.

 

Just make sure you don't block the front air dam because that pulls up a lot of air to help keep the engine cool.

 

What I explained is applicable to both FWD and RWD vehicles. As you stated, on a FWD vehicle you would want to focus on the downward force on the front. The design of the splitter may/may not slow you down and possibly defeat your purpose by actually lifting the front end. But that's only part of the problem. The biggest problem is the air flow under the car. With a front splitter only you will be disrupting the flow and create turbulence under the car. Why? Because the front splitter creates a high pressure area and the rear creates a low pressure (vacuum) area. The rear splitter aids the front spoiler by keeping a high velocity stream of air being 'sucked' out the rear of the vehicle.

Spoilers/Wings: Even with a FWD vehicle downward force on the rear of the vehicle is a big plus. It will aid greatly in keeping the vehicle 'glued' to the road. There is a high pressure area behind the rear window that can be reduced/eliminated with a spoiler. The spoiler will smooth out the air flow and apply downward force to the rear of the vehicle. A vertical spoiler does a much better job of this versus a horizontal spoiler.

I'm not trying to deter you from your project - go for it! I'm interested in what you come up with. I was just pointing out some of the hurdles that you will need to address if you want a truly functional splitter.

Have fun - That's what it's all about!

 

Ok thanks. I might see if I can get someone to look at it and decide whether or not it will make a difference. I might not even do it but thanks for the advice

 

Way too aggressive looking for a stock car, ps, isn't the OP 15 years old? It's hard to see how he will have access to tools and materials (money) and most of all knowledge on how to use power tools?! But in all honesty way over the top too aggressive for a stock car.

 

i say go for it i would like to see this completed, i would make a rear diffuser to go with the front splitter though so it looks right. also spoilers play a huge rule on any vehicle at high speeds. no matter front or rear wheel drive when in a turn the back end gets light and you need a spoiler to put pressure on the back end to keep from spinning out.

 

The 06 Nascar inspired spoiler on the 06 and 07 SS does it do anything to this? are is it just for looks.

 

As far as daily driving goes it is basically ornamental. It does aid in reducing wind drag, but downward force would be minimal to nonexistent. You'd have to drive your car at a very high rate of speed to really see any benefit.
