Ok, I got it. For every 1/8 inch hole I drill out on my car it reduces .025 of a lb. So, if I start now I will have drilled one million holes by the age of 50, and my car will weigh about 3 lbs. I calculated the results on a quarter mile calculator and with about 200 whp my car will run 1.437 sec. in the quarter mile.

tirerack.com had some Kosei split five spoke 17" wheels that weigh 13lbs and 18" wheels that weigh 16 lbs..that is about 10 lbs less compared to stock wheels and that is huge when it comes to wheel weight

Thinking about it, I have a 99 tl I/H/E. Its definitely a pretty quick car, possibly a HIGH 14 second car. The engine has potential, but what makes it a quick and not a fast car is that they weigh over 3400 lbs. I have removed the spare and jack already. My question is if my car was just under 3000 lbs it would make the biggest difference in performance. Weight makes the biggest difference, but there just isnt anything that you can remove to make these cars lighter. Any ideas?

I beg to differ! 500+ lbs removed from a 3rd Gen. Basically like adding 65 hp to the car, but with MUCH better handling and braking dynamics.

First and foremost, this is a subjective thing (based on one's opinion).
However, I feel IMHO that most guy's on this forum would disagree. My car is a daily driver. I commute 52 miles round trip per weekday through Houston during rush hour. IMHO, my car is far, far from being barely streetable.
Cite me some logically arguments as to why you feel that my car is barely streetable.
If "barely streetable" is you opinion, then ok. I will respect your right to voice your opinion. Cheers

Go to the DIY page and follow the directions to fix that. Its a 1 hr job for the first timer and only costs 5 bucks in carb cleaner. You will get better mileage, idle and run better as well.

Did you know that the government requires auto makers to have "5 MPH" bumpers on cars ? This means that the car must survive a 5 MPH crash without exceeding a certain dollar value of damage.
Here is some info, brought to you via
SOURCE: http://www.nhtsa.dot.gov/cars/proble...per/Index.html
1) What is a bumper?
A bumper is a shield made of steel, aluminum, rubber, or plastic that is mounted on the front and rear of a passenger car. When a low speed collision occurs, the bumper system absorbs the shock to prevent or reduce damage to the car. Some bumpers use energy absorbers or brackets and others are made with a foam cushioning material.
2) What is the purpose of bumpers?
The car bumper is designed to prevent or reduce physical damage to the front and rear ends of passenger motor vehicles in low-speed collisions. Automobile bumpers are not typically designed to be structural components that would significantly contribute to vehicle crashworthiness or occupant protection during front or rear collisions. It is not a safety feature intended to prevent or mitigate injury severity to occupants in the passenger cars. Bumpers are designed to protect the hood, trunk, grille, fuel, exhaust and cooling system as well as safety related equipment such as parking lights, headlamps and taillights in low speed collisions.
3) What are the Federal regulations for bumpers?
49 CFR Part 581, "The bumper standard," prescribes performance requirements for passenger cars in low-speed front and rear collisions. It applies to front and rear bumpers on passenger cars to prevent the damage to the car body and safety related equipment at barrier impact speeds of 2½ mph across the full width and 1½ mph on the corners.
This is equivalent to a 5 mph crash into a parked vehicle of the same weight. The standard requires protection in the region 16 to 20 inches above the road surface, and the manufacturer can provide the protection by any means it wants. For example, some vehicles do not have a solid bumper across the vehicle, but meet the standard by strategically placed bumper guards and corner guards.
4) Are all vehicle classes required to meet the Federal bumper standard?
No. The Federal bumper standard does not apply to vehicles other than passenger cars (i.e., sport utility vehicles (SUVs), minivans, or pickups trucks). The agency has chosen not to regulate bumper performance or elevation for these vehicle classes because of the potential compromise to the vehicle utility in operating on loading ramps and off road situations.

Here a some pics of my '06 TL
To answer the question "why". This is why.
Here is an comparison between the TL Diet and the advertised HP gains of the S/C.
Wow... sorta looks like the TL Diet is equivalent to TWO superchargers !!!
EQUIVALENT HP INCREASE
------------------------------------
(3580 lbs / 2863 lbs) x 258 hp = 323 HP (equivalent output)
323 hp - 258 hp = 65 HP (equivalent increase)
Note: This is not just a peak hp increase. This is
a 25.0% increase across entire rpm range
for both the HP and TORQUE power curves.
-------- The TL Diet: Woo Hoo, What a Ride !!! --------

WOW.... thats some extensive stripping work.
the only other thing i can think for you to take off are the door panels. maybe a custom CF hood and Trunk.
ButI think leaving the carpets, panel, radio, centre console would be best for your daily driver =)

I did review how the TL is made, and I am comfortable with leaving my front bumper off. The lack of a front bumper might hamper safety to a small degree. But, think about it... how much protection is that bumper during a 60 MPH frontal collision ? The bulk of the protection comes from the design of the car body (pic below) and the aluminum front cradle. I am convinced (for my own sake) that the TL bumper is primarily a "5 MPH" bumper.

I disagree. I am very mechanically inclined and I was aware of this potential bracing that the bumper might had been adding. However, upon further thinking and real life experience with it removed, it does not provide any bracing imho. If you look at how the bumper is bolted onto the body, you can see that the mounting can not provide any meaningful bracing (leverage). I propose that the weight reduction of the removed bumpers added more rigidness to the car from the less stress of supporting that weight.

Forgot to clarify that misunderstanding. I meant that my driving experience with the bumpers removed did not show any reduction in frame stiffness with the bumpers removed. On the contrary, the car was much easier to toss into turns and more nimble and precise in curves.
