I know you Mazdaspeed guys have each others backs. If you look again my post suggests pressure cast wheels not take out a second mortgage on forged wheels. I know price is important otherwise you wouldn't be looking at Motegi in the first place. Wanna get the drop on evo's off the line instead of getting destoyed, get lighter wheels and wider tires so you can get the jump and actually hook up quicker. Mitsu has u beat both ways. More hp and less unspring weight. Evo=18 lb wheels. MS3=25 lb wheels. If you like those Konigs here's some pics of the real deal. Wedsport SA-55M.Hey Warlord, while I do appreciate your opinion I do know that lighter wheels make a diff.. this is in my budget. they are like 150 a wheel. If you got 3.300 I can have I will cop some gramlights I want these but hey they are like 23 lbs each and they are like $810 a rim. But, Like Cpecktv said, I am not tracking the car, even though I maybe buying some Cobb sways.
Either way if I lost 3 lbs a rim that would not make much diff. It takes 100 lbs and make a 1/10 sec on a quarter mile.. you telling me a total of 12 lbs will make a diff... I would be better off going on a diet.. lol or kicking my girl out the car. you know what I can do .. take out my spare and jack... that is more than 20lbs... what do you guys think?? it would be the same as have 17 lbs rims
Cpecktv.. you have no idea what grief my girl gave me for even bringing up rims.. lol
Actually, it would make a noticeable difference.Either way if I lost 3 lbs a rim that would not make much diff.
I think you are confused between sprung and unsprung weight. Wheels are unsprung weight, and therefore make a big difference in how your car handles.It takes 100 lbs and make a 1/10 sec on a quarter mile.. you telling me a total of 12 lbs will make a diff... I would be better off going on a diet.. lol or kicking my girl out the car. you know what I can do .. take out my spare and jack... that is more than 20lbs... what do you guys think?? it would be the same as have 17 lbs rims
SourceSprung vs. unsprung weight.
Simply put, sprung weight is everything from the springs up, and unsprung weight is everything from the springs down. Wheels, shock absorbers, springs, knuckle joints and tyres contribute to the unsprung weight. The car, engine, fluids, you, your passenger, the kids, the bags of candy and the portable Playstation all contribute to the sprung weight. Reducing unsprung weight is the key to increasing performance of the car. If you can make the wheels, tyres and swingarms lighter, then the suspension will spend more time compensating for bumps in the road, and less time compensating for the mass of the wheels etc.
The greater the unsprung weight, the greater the inertia of the suspension, which will be unable to respond as quickly to rapid changes in the road surface.
As an added benefit, putting lighter wheels on the car can increase your engine's apparent power. Why? Well the engine has to turn the gearbox and driveshafts, and at the end of that, the wheels and tyres. Heavier wheels and tyres require more torque to get turning, which saps engine power. Lighter wheels and tyres allow more of the engine's torque to go into getting you going than spinning the wheels. That's why sports cars have carbon fibre driveshafts and ultra light alloy wheels.
We are talking about street driving right?.... I know what Rotational Mass is as well.
Reducing unsprung weight is something you'll feel every time you get in the car and hit the gas, step on the brake or turn the wheel. If you like your MS3 now you'll love it even more with lighter wheels. If more performance for a tenth of what bolt on hp costs doesn't float your boat then it's all good by me. If it's going to mean that your gonna have to sleep on the couch then MR116 were made for you. I do like the color just not the weight. As far as the difference between 18x8+35 and 18x9+35 with 235/40. It's flush vs. stretched hellaflush with extra camber to avoid the poked look.. 8.5+35 is perfect for a MS3 but they don't come in that size.
