Do Lighter Wheels Make Car Faster

Always ask about the weight of wheels. The stereo is a prime target too along with all.

Are Lighter Wheels A Waste Of Money

Plus-size tires do have their downsides though.

. Not by very much but you will be able to feel the difference in how it goes into corners. And especially the old 1000hp F1 cars. Bigger wheels can add more weight to each corner of the car and those short sidewalls mean a reduction in the tires inherent spring rate leading to a rougher ride over pavement irregularities.

Your vehicle is not engineered for heavy wheels. It takes approximately 18 lb-ft of torque to get those 21lbs wheels spinning up to 80mph. The more you have the faster you go - hence the Veyron SSC etc.

So 5 lbs per wheel x 4 wheels is 20 lbs savings from the car right. Remove or swap heavy electrical components. Get Tires With More Grip via trackdays Theres no point in increasing your cars power if you cant get it effectively to the ground so its time to fit some fat and sticky tires.

Wheels are not sprung weight so the car not only has to accelerate the weight of the wheel but also has to over come the rotational inertia. Reducing rotating mass should make the car accelerate and stop faster as well. Speed is based mostly on aerodynamics power and torque though a lighter car will benefit acceleration times and would require less power and torque.

Dont forget the electrics. If you just spend more buy a better wheels thats strong light weight you can improve whp gain handling braking acceleration all with 1 single purchase. Improving handling road feel braking acceleration and even fuel economy.

The larger difference is in the suspension action. We always hear that lightweight wheels are better. I find the biggest impact to a car with heavy wheels is ride and handling.

Inertia is how much resistance to change in movement it has. If your car is old you can removechange the air conditioning compressor which is around 5 kg. With lighter weight wheels you will benefit from increased fuel savings quicker braking improved tire wear and better acceleration.

Lighter wheels is a modification that in isolation doesnt do much but at the extremes of performance become more important. Reducing unsprung mass theoretically helps a cars suspension work more effectively. Here are a few ways to make your car lighter and faster.

Lighter is faster as long as you got enough downforce weight to maximize grip. Its also rotating mass which is three times harder to accelerate that sprung weight so getting some lightweight wheels can really improve performance. Some people go to extremes such as in the image above.

Here you WILL notice a difference. But you can also achieve that effect by stripping out the excess weight from your own car so that it can run faster. As far as acceleration we all know that with the same power making your car lighter WILL make it faster.

A further 10 or more kilos can be shed by removing the heater matrix fan and associated piping. But as mentioned it also contributes to alter CoG. A lighter wheel move more easily to follow the road surface - it has a less inertia to overcome and accelerates more quickly on compression and.

Watch this to find out first-hand. Its a pain to steer. Others might decide to take out the rear seats of they never use them or the fixtures and fittings from the trunk.

In theory larger wheels also provide more room for bigger brakes. Lighter wheels help your suspension rebound faster and reduce the inertia of the wheels. From the dyno chart you can see the effect of replacing factory wheels with lighter HRE wheels and see the negative effects of installing heavier aftermarket wheels.

Lighter wheels and axles mainly contributes to the same effect as a lightened flywheel would in a real car. However after doing some reading around the Internet recently Im not so sure any more. The unsprung mass of a car is key to this.

As soon as the grip fails your power is converted to heat instead of speed by spinning the wheels. It isnt much bigger than the steering wheel was on my old Carter Go-Kart. There just doesnt seem to be an abundance of empirical.

Every 1 lb reduction in rotating mass is equivalent to an approximately 8 lb reduction in static weight. When a wheel is spinning its inertia to left to right movement is increased by the velocity of the wheel. Answer 1 of 8.

Do lighter wheels make my car faster This is a very subjective topic and certain magazines have performed tests with varying results. Does putting lighter wheels on your car make it feel different. Yes lighter wheels will make you somewhat faster in first and a little faster in second.

Sean Chaudhry Town Country BMW 416 875 0931. Here is the study from DBA brake from Australia. Also depends on the cost of going light.

Ive always held the belief that shedding unsprung weight by going with lighter wheels reaps major benefits. Paying double for a wheel which is 2 kg lighter is not worth it unless you drive an F1 Car. If youre putting together a racer chances are you dont need a load of extra electrical gubbins like rear wipers power mirrors heaters and interior lights so if youre removing those you might as well get rid of the extra wiring too it can stack up more than youd imagine.

Saving just 5kg per wheel knocked 3secs off the lap time 05secs off the 60-100mph time 08secs off the 80-120mph time and even stopped the car 15ft sooner from 100mph. Anytime you can reduce weight from a vehicle it is a good thing. Less weight means quicker acceleration shorter braking distances and more responsive handling.

The less drag the car creates note the Veyrons super-slick super-clean design versus something crazy. On a different test I took 33secs off the 30-90mph time by improving the bhp per tonne by just 20bhp from 105bhp to 125bhp per tonne. I have to turn the wheel all the way around a couple times to do a right then all the way to the left to not go off the road.

Wheels and tires contribute to drive-train losses as energy is used to spin up the wheels and decelerate the wheels under braking. This system replaces the undriven rear wheels with a pair of motor-driven rims that provide an additional 50 horsepower and 70 pound-feet. The Original Steering Wheel is in the back seat of my Biscayne and the Previous owner put a tiny aftermarket wheel on it.

The lighter the vehicle the faster it will travel its simple common sense.
