I would like to know, how to lighten my 997 Carrera S, by removing the
rear seats???? I have the rear muffler by-pass and ordered the side mufflers
from Fabspeed. What else???

 

I know for me, the biggest weight reduction would be to hit the gym a few times a week!

 

Yup that ^^^^ and the biggest weight saving would be to never run more than 1/4 tank of gas.

 

I only weigh 198lbs. I don't think hitting the gym would help. I only have 3% body fat. How about you. lol

 

^^^ Gotta get to that 5th grade pre-puberty body weight bro. haha.

 

This reminds me of hearing a few aircooled guys talking about how they like to always have approx. 3/4 of a tank when tracking for front end traction.

But being serious, you can also remove the rear subwoofer, I’m not sure how much it’ll save. Probably not something you’d feel on the street.

 

Wheels. A set of good quality forged wheels can drop close to 40 lbs ( about 10 lbs on each corner) depending on which stock wheels you have and how much you spend on the new set of forged wheels. They not only weigh much less but also add strength compared to stock cast wheels and reducing unsprung weight on the wheels is probably the most effective of the weight reducers to actually increase performance. Next would be seats. The OEM GT2 carbon fiber bucket seats are almost 50 lbs lighter than any of the other stock seats. Not each but for a set of 2.

Neither of these two mods are cheap so you really need to be in a serious weight reduction mode to justify the cost. Just to put things in perspective, the exhaust mods you did may add up to a drop of 20-25 lbs. The wheels and seats just described will approach a reduction of 100 lbs combined.

 

Manual sport seats instead of power ones, forged wheels, and PCCB brakes.

 

I've ordered forged wheels, 16.3lbs, do you know what the stock wheels, from P weigh ???? They are 19" and are the turbo wheels. Any idea how to remove
the subwoofer??? or the rear seats??? The car is for autox only, Do you have a link to the OEM gt2 seats????

I've taken out my back seats. Most of the rear carpet (which is heavy) the subwoofer, the subwoofer shelf, and all the insulation padding that is stuffed into the nooks and crannies in the back of the car. Probably pulled out 50lbs + from the back. Did the 3rd muffler delete, super lightweight forged wheels. The front seats I'll do when I can.

 

Sub and rear seats are pretty self-explanatory once you wedge yourself in there. The rear seats you just need to fold them down, then remove that mount on the center tunnel and you can slide them out of the side mounts.

The only trick to the subwoofers is you have to pop off the trim rings around the air ports which will reveal little black screws. Once you take those out you slide out the air ports and that will reveal the larger mounting bolts for the sub enclosure.

If you have any plans to add TPC's DSC controller in a .1 car, now is the time to do it as the DME you need to tie into the wiring of for the 3-axis accelerometer is back there under the sub shelf.

Search is your friend...

I took mine out of my cab, mainly to give more clearance under the wind deflector for my golf clubs.

 

I swapped my rear seats/all seat belt accessories and subwoofer for the agency power roll bar, it was an even swap at 45lbs IIRC.

The exhaust is a good way to shed pounds as well, with my custom setup I was able to cut it to less than 1/2 the original headers/cats/mufflers weight. I made a custom one piece Cats/single muffler with integrated x-pipe with weight savings being the #1 priority.

Get an aftermarket FRP or carbon fiber deck lid and you'll save a ton of weight too, I can't remember specifically but it was a significant weight loss not having the bulky metal lid and spoiler and spoiler motor.

 

If you are 198# and three perent boy fat I’d say to forget about GT2 Sport Buckets (unless you are 6’6”). They are narrow without very much padding, like they were made for skinny european in mind. (I love mine during the cycling season when I am around 155#, less so in the winter when I’m 15+ pounds heavier.)
