Heavy Spare Tire

No, not on me but in the trunk of the IS F. On Saturday I pulled the spare tire out of the trunk and realized that it's fairly heavy, probably 40-45 lbs. Then I took out the tool kit and the jack which, combined, probably weigh at least 10 lbs. That is a savings of some 50 lbs or so. I drove the car and it felt a little quicker with that weight gone. Of course this could have been wishful thinking on my part. Just wondering: Do any of you drive without the spare to save weight? I put everything back in the trunk as with my luck I'd get a flat.

i believe the spare weighs 37 lbs.
i got rid of mine spare as soon as i bought the car. i also got rid of the tool kit and bought an aluminum jack on ebay to replace the steel one.

i don't run mine at all my trunk is empty..and it does feel a little lighter in the rear... hence the euroteck rear defuser to help stablize the rear end when driving at high speeds..

I thought the euroteck one was wind tunnel tested and fully functional, hence the ridiculous selling price
edit: found the thread where eurotech says "we decided to use our state of the art advanced CSWT (Computer Simulated Wing Testing) software...The result equates to improved high speed stability and reduced rear end lift."

i cut a piece of thin veneer and wrap it in black cloth. looks OEM and is 10x stronger. a couple strong styrofoam blocks in the middle works well as weight support.

As a daily driver, I would leave the spare tire and tools in the trunk. You will regret not having them when you get a flat. If you track/drag your car, then remove all the items and you will save about 50 pounds.
Or as tenspeed stated, just always run a quarter tank of gas and you will save 100 pounds!

On my 350, I saw a more noticeable difference when unsprung weight was removed via the wheels, but even then, I don't believe it was consistently measurable, by itself (and certainly not on the street).
So yes, the spare stays on board.
