Today I was doing some work at a Fed-Ex terminal and we were working right next to a scale. It was a one axle scale. My car is a fully loaded 03 5AT sedan with the Aero kit. Extra weight in the car included me (~180lbs), two child seats (20lbs), 60lbs of tools/gear and a 30lb cooler in the trunk, all weather floor mats (21lbs), and aftermarket 18" wheels (+12lbs). The car was filled up just before entering the property (152lbs).

Front axle - 1920lbs (51%)
Rear axle - 1840lbs (49%)
Total weight - 3,760lbs

Without me, the extra gear, or the aftermarket rims, the weight with full tank of fuel comes in at 3,440lbs. At the strip, I run with a 1/4 tank of fuel (-105lbs) and no spare (30lbs). That would bring the race weight into the 3,300lbs range. I tested the scale by weighing myself and it said 180lbs which is spot on.

 

theres a truck scale in my area that we weigh at and my car weighed 3500lbs, without me and with 1/4 tank of gas. This scale rounds the the nearest 10lbs. So +/- 10lbs, 3500lbs for a fully loaded stock 2005 5AT, not too bad.

 

weighed mine a couple weeks ago... 1/4 tank gas with everything in the car (except me): spare, jack, all floor mats, 3 trunk mats (bottom, b-quiet, top) big torque wrench, detail product box (maybe 50lbs of stuff all together)

Car weighed 3380 - most scales read in 20lb increments and round to the closest 20lbs - so it could be as much as 3390 in reality (or 3381) - not bad for having 19" wheels

with everything out I could get it down to 3340 or less... I'll weigh it again some day with everything out

 

Wow, I expected to see higher numbers. I taked to a coupe guy who weighed his car at the track the other day and it was ~3850lbs. That's a coupe with kuruma z bumper, 19" volks, no back seat or spare, TN turbo kit and him ~200lbs.

 

You need to subtract 2% from that final weight. That's how the commercial officers do it when they weigh big rigs out on the road with their portable scales.

 

Wow! If I take the 3,440lb assumed loaded OEM weight and multiply it by 0.98, I get 3,371 which is almost exactly what the DMV registration lists my car's weight at (3,370lbs).

 

3850????????????????? WTF?! that sux!

 

Sounds about right to me. His mods add some weight and his 200lbs puts his car around 3550-3600 which is right for a coupe.

 

I'd agree. The wheels and tires probably added 30lbs, he turbo gear adds around 50lbs, and he weighed 200lbs. Put the spare and back seat in and his car is in the range I'd expect for a loaded coupe (3550-3600lbs).

 

I lost weight with 19" Volks.

 

The rims might be lighter, but 19" tires are very heavy because of the heavily reinforced sidewalls. A 215/55R17 usually weighs around 24lbs, but a 245/35R19 is around 29lbs.

 

mine was 3300lb even, with 1/2 tank gas, no spare.

 

nope, my 245/40/19 are 26lbs, my 19X8.5 Volks are right about 19lbs (just under according to Mackin)... I can’t remember the weight of my 17" combo, but I can assure you when I researched the size, weight and type of wheels and tires I went with this entire subject was my primary focus. And my current combo is right at or slightly less than the 17" I was running...

The sidewalls of the 17" profile is taller so there isn’t much weight savings - I went with Toyo T1R specifically because it was one of the lightest I could find... unfortunately they have been reported to have a soft sidewall (that might be why they are lighter than what you have found most to be)... I haven’t noticed any negative handling characteristics from these tires though.

 

what all did you do to lose weight? I know your suspension is probably lighter...

Speaking of which, I replaced OEM A-Arms (which are REALLLY light! With SPL - WAYYY Heavier... but the rotors I'm using are lighter than OEM so that helps.
3300 is incredibly light (for our car) - I'm interested to know what tricks (if any) you did...

 

^nothing major that i know of, Custom exhaust, Stoptech front rotors, OEM 19s. Those are the things i can think of.
