My curb weight

[cmore]

I had my car weighed on a scale that has is calibrated to +/- 10lbs. With my modifications and options, it came out to 4,075lbs. I was hoping to get under 4,000lbs, but I think I am at the limit without going to extremes with light seats. For now, this is good enough. :)

Are you using a lightweight battery? The Odyssey 925T saves about 39lbs over stock. Remove the Onstar module and battery for 1~2#'s. Do you have Forged wheels? Forged wheels will save upto 40# or more over stock.

Here's all of my current modifications regardless of weight savings or not:

O.CT engine chip
O.CT transmission chip option
PSS9 Coil over and 9-way adjustable dampers and springs
Hotchkis sport front and rear sway bars
18"x9" wheels with 12mm spacers
255/35/18 tires Goodyear F1 Asymmetric tires
Milltek stainless steel cat-back exhaust systems
Milltek turbo downpipes with high flow cats
Hyperboost diverter valves
Odyssey PC680 light weight battery (http://motorsports.chrismore.com/2010/03/audi-rs6-lightweight-battery-install.html) - saved 37lbs
ECS Tuning silicon vacuum hoses (http://motorsports.chrismore.com/2010/03/audi-rs6-replacing-vacuum-lines.html)
VDO boost gauge (http://motorsports.chrismore.com/2009/12/audi-rs-6-boost-gauge-install.html)
Spare tire removed (not really a mod, but helps)

My wheels are not forged and only 4lbs lighter per wheel than stock. Don't have the $$ for lightweight forged wheels, but I do agree they are nice. :)

I haven't taken out the onstar system as a pound or two is equal to eating dinner. Maybe I will if I get bored one day.

Something seems off, I weighed my car at the track with 10 gallons of fuel, Odyssey Battery, Milltek, etc. and no spare at 4250lbs.

I had 1/4 tank of fuel when I weighed my rs6 and our cars vary quite a bit in curb weight depending on options. I also don't have the solar sunroof. do you?
