^ that wasnt meant for you specifically.. just, pointing out that although the absolute weight savings may sound small, it will make a big difference

unsprung weight is king! exactly why the fidanza flywheel completely stomps the others, and why Charles R. Hill's flywheel upon release will hopefully even surpass that. Can't wait for that ;)

Do you lot want to tell him or shall I? |
I'll tell him -
get lightweight springs for your flywheel - Unsprung Weight FTFW!!!11!one1! :lol2: S:lol2: |
No one has mentioned 2 piece rotors. About $325 each and should save about 5 lbs. per corner. Yes, they are just as expensive as lightweight wheels, but another option.
|
I'm saying how much weight per corner. 7.5 pounds per wheel is a riduclous weight savings and also nothing that will come inexpensively. You are looking at forged magnesium to attain weight loss like that from wheels alone. LM= U-Mold >>21.5 lb. H= Hitachi >>22.5 lb. If you believe Tire Rack weights, then Kosei K1-TS 17x8 +45et $199 >>15.4 lb. MOTEGI TRACK TRAKLITE 17x8 +45et $288 >>15.0 lb. MOTEGI TRACK TRAKLITE 2.0 17x8 +45et $288 >>14.6 lb. Enkei Racing RPF1 17x9 +45et $250 >>15.5 lb. So you'll be looking at 6 to 8 lbs savings depending on which stock wheels you have and which wheels you end up choosing. No forged mag necessary. And you'll probably end up saving about 2 lb. with a 235/40-17 compared to the same model of 225/45-18. I looked up PS2s, that was the number. I normally play pretty nice, but you said ridiculous, so... :pokeowned You got me to look at the battery in more depth, too. Oddyssey PC680 is about 13 lb., if I remember right. Stock Small Battery - 21.1lbs Stock Replacement Battery - 37lbs So you're looking at either 8 lb or a massive 24 lb. off the nose. Not recommended if you have winter, though. |
My mistake, I was only looking at weights for 18's via Wheelweights.net. I didn't bother looking at 17's like a fool.
The battery is nice... but I fall into the winter category. My car is under a bunch of snow at the moment. |
I have the smallest car battery i could find - no problems . And yes we have a winter (-1deg C coldest it gets) ..... but I do have a garage .

owned twice in one thread - you are having a bad day ..... |
lol not really... Get "owned" by people who enjoy their best part of their day by E-owning other people makes me laugh harder than it actually makes me upset.
Besides I got my new shift boot and it's sunny for once. Not having a bad day at all! |

|
Lol thanks for taking the focus off of me at least

There are 3 categories of weight= unsprung weight = shocks, brake calipers, brake pads, brake lines. sprung weight = the car and anything that rests on the springs rotational weight = brake rotors, engine rotors, pulley, flywheel, clutch, transmission, driveshaft, final drive gear, wheels, tires. |
I hear Tein sell uprated springs for the clutch disc, they even make progressive ones:lol:

So after doing search after search i have decided to start a thread hoping to get the answers i am looking for. I am looking for solid, proven ways to increase acceleration without going FI, too much to maintain, i already know about intake, exhaust and flywheel, but what else out there has been proven????
The Navy uses a steam cat.....:D: Seriously, you forgot gearing, Mazda is dropping down to a 4.77 this year. Lower, wider tires would help a small amount. |

Unfortunately this is not true for the most part. Try going to 275/35/18 for example on whatever wheel (9" or 9.5" would be appropriate). You'll not only NOT accelerate as fast, but your top speed will drop due to additional friction (air/tire). Even if you get nice lightweigh wheels...:banghead:
Uh, the stock tires are 225/45 18; a 225/45 16(?) would be "smaller" and lower the effective gear ratio. I guess the steam cat is not really an option..... |

I've heard the Japanese minister of transport has funded the "steam cat at every stoplight" program.
