Inside Centerline Wheels
Centerline was brain-child of founder Ray Lipper in 1970, who is known as the grandfather of modern aftermarket wheel industry, a SEMA hall-of-famer and motorsports lover and driver. Since it's inception, Centerline has always continued to focus on building the best, most advanced rims in the entire world.
Center Line uses a process known as cold forging to create a strong wheel that maintains its luster and quality. They have designed a rotary forging press, the only of it's kind in the entire world, it compresses a rock solid billet of aluminum with over 4,000 tons of pressure, at 300 revolutions per minute.
This process not only rearranges the aluminum molecules, but it aligns them in a pattern that gives it more strength to withhold the outside forces of the outside world. Because of this process, CenterLine rims are much lighter, stronger, and more durable than any other wheel on the market.
Centerline Racing Wheels
For a racing wheel, I recommend going with the competition race & street wheels as they are the lightest and are the best wheels for racing drag at the track.
Centerline Truck Wheels
The most popular truck wheels are by far the Centerline Archer rims. They come in two different sizes: 20 inch and 22 inch in diameter. The next most popular wheels are the Voltage... It's chic finish, and clean lines make it a standard in the truck/SUV world for a light customer billet wheel.
Centerline Drag Wheels
If you're looking for a drag rims, I highly recommend the Competition Qualifier. It's a really hot 5 star wheel that you see everyone at the track riding on. It's because they work, they're light, and are a nice set to have when you're ripping down the street in your Camaro, Mustang, or Hot Rod.

Car Battery Care Tips - Battery Care and Maintenance Tips
For every vehicle on the road, the car battery is most important component. If the car battery has any malfunctions whatsoever, then you will not be able to start your car. Most car owners will be facing problems sooner or later because vehicle lead acid battery has a limited lifespan.
If you have a regular battery maintenance schedule for the health of your car battery, then you can have a smooth start each and every time you want to use your automobile.
Here are some tips you can use to take care of your vehicle battery to get it working properly. When you parked your car, you should avoid keeping car headlights and other lights on for a long period of time. This will definitely drain your battery.
When the air conditioning unit in your vehicle is not required, it is best to switch it off to conserve power. If your vehicle is using a weak battery, try restraining from unnecessary honking. All these electronic components in your car will be draining on your battery bank thus sending its charge level into a low state. When a lead acid battery is discharged to a very low level, it is almost impossible to bring it back to its maximum power efficiency.
Here's a simple battery checking step you can do on a weekly basis. Check on the battery to make sure that there is no corrosion or rusting on the battery terminals. Rusting or foreign residue accumulated will cause the problems of difficult start ups because there will be a loss of surface contact between the electrical cable connectors with the battery terminals.
To prevent residue from building up, you can use a battery corrosion glue and sprays it on the terminals of the battery. This is usually the root cause for all car ignition problems. If you find any bluish green or white powdery layers forming around the battery terminals, then you have to take certain necessary steps to remove it or it will cause additional damages.

How to Make Your Noisy RV Furnace Quiet
Have you ever cursed your RV furnace for waking you up in the middle of the night? Have you ever had to turn up the TV a few notches when the heater kicks on? RV furnaces are notoriously noisy for a number of reasons. Generally, most of the noise comes from the high-speed fan which is then amplified by the enclosure the furnace sits in. This how-to focuses on how to reduce the furnace noise using soundproofing material and a little airflow trick that will lower the noise level to a dull roar.
Step 1: Measuring enclosure
Start by removing the air return register and inspecting the inside of the furnace enclosure. With a tape measure, measure the dimensions of the top, back, and sides of the enclosure. For example, the top of the enclosure may measure 24" x 24". Tha's 2' x 2', or 4 sq. ft. What you are doing is measuring the total square footage of the enclosure interior where you will be placing the soundproofing material. Typically, about 6-8 sq. ft. is required, unless you have a really big enclosure, like the inside of a dinette bottom storage area.
Step 2: Determine airflow requirements
Now get out your furnace manual. Find out how many square inches of return air area the furnace requires to operate effectively. For example, a 30,000 BTU Suburban furnace requires 54 sq. in. of opening area for the air to flow through the return grill. This size furnace usually will have a grill that has 4 sets of louvers. Only 2 are actually required to support the return air requirement, which in this case is about 60 sq. in.
Step 3: Adding soundproofing material to register
Next, add some soundproofing material to the back of the register. Much of the blower noise is transmitted through the front of the register, so it makes sense to try and reduce noise here as well. In the example in step 2, you should apply soundproofing material on the back of the register over the middle two of the four louver columns. This is OK to do since you are still meeting the return air requirements of the furnace.
Step 4: Adding soundproofing to the enclosure
Cut the soundproofing material to fit your measurements of the furnace enclosure and affix to the walls (sides, top, and back) of the enclosure. The material suggested in the parts source link below can be had with a peel-and-stick backing, making the attachment of the material very easy. It costs a little more than the non-sticky stuff, but you won't have to use any glue if you choose this type.
Step 5: Install return grill
Re-attach the return air grill and turn on the furnace. Let the furnace run through a complete cycle to ensure everything is working properly.
Tips and warnings:
You can expect a reduction of about 6dB of noise level. How much is this? The human ear perceives sound levels of 3 dB as being twice as loud or quiet. For example, if you measure your furnace noise output, it might be 61 dB at 5'. Reducing the noise level to 58 dB would be perceived as twice as quiet. With this mod, using the 3/4" material, your furnace could be a much as four times as quiet! Now you won't have to turn up the TV every time the furnace kicks on!
Ensure that you provide adequate air flow through the return air grill by adhering to your furnace's minimum air flow requirements specified in the owner's manual. Otherwise, the furnace may perform erratically or shut down due to overheating.
