    Trans Am getting skinny

    Well, I have decided to basically turn my Ta in a street driven race car. So this winter project is to upgrade the nitrous kit (current one is for sale) with an ls6 intake and put this thing on a HUGE diet with some suspension parts w/ cage and IF i have time I will be putting a custome BRE cam, but only if I have the funds and time left. well I have finally parked the car and decided to start tearing into it. I will update this as I go with pics and weights that I remove and add. The car did a best of 11.19 with only back seats removed and a 125 dry shot with some little issues. Goal for next year is mid to low 10s on a 150 shot.

    Items removed
    Rear seats
    Windshield washer resovier
    AC system
    Front sway bar
    Traction Control and Cruise control
    Front Seats
    All seat belts and brackets
    Speakers

    Will be getting the weights once I go get a nice scale.

    here is what is off so far




    As far as purchasing parts, the only part that I have received so far is my new Midwest Chassis Tq-arm w/built in dsl to custom fit my T/D exhaust





    Engine bay starting to look alot cleaner without the ac, tc/cc bs all over it


    Today I got the seats, all the interior plastics, all speakers out. next will be the center console and carpet and then hopefully by then I will been able to get time to stop down JJsautomotive to get my new dash and wiring so i can start that so I can do my own custom wiring harness.

    Car interior will be getting chromoly 8pt with two kirkey seats, speed inc lightweight carpet and switch over to ebony interior. Interior/dash harness will be gone through and everything not necessary or been deleted, will be deleted from the harness and dash. Only creature "comforts" that will be left is the heat, power windows and power door locks.

    isnt the front sway bar kind of important?

    This is mostly a track going straight car. And im already riding around on skinnys up front so removing the sway bar isnt that big a deal because I do not take turns at barely any speed at all. Reason to remove for the track is better weight transfer and allows the front end to come up quicker and also less weight which also helps is weight transfer.

    This sounds like a great project. I would like to know how much weight you take out and see just how far you go. Of course the limiting factor is always money, but a tubular k-member would help lighten the front end. You running a stock rear end? The LS6 intake will be a nice upgrade. I've got the FAST 102mm LSXR intake on my Christmas list, but I'd also have to get a larger MAF and TB. Don't think Santa's got that much extra cash this year! But one of these days I'm going to do a Heads and Cam upgrade and get serious. Wish you the best and enjoy your machine!

    I am going to go far enough to hopefully sit at 3200lbs. I will document every oz I take out and every oz i add. Really the only weight I will be adding is for safety which will be the cage. Alot of things add up that you wouldnt even think of. Leather seats, oem carpet, back seats. Right there is almost 100lbs..

    The money will be spent on all Chromoly suspension pieces and cage from Midwest Chassis. They have the lightest pieces out there. I will be doing a tubular k-member, a-arms, manual steering, abs delete and the list goes on. Haha.

    Thats a sweet setup.. We used that when determining the CG of our airplanes. Those are nice to have. Im South central sorta.. I see your from Mansfield. If I am thinking of the same place it was on my way to NY when I lived up there and I would come home to visit my parents.

    I took mine off to go to the track once about 6 years ago, I noticed no difference on the street so I've left it off ever since.

    I have debated ditching mine at the track but have received conflicting feedback as to any benefit. The stock bar is hollow and really does not weigh all that much. I understand that removing it is supposed to allow the front end to rise more/quicker for better weight transfer. Anyone know for sure?

    I havent got any vids of me launching with it off, but i can def tell a difference on the street. It lifts up alot faster and more. Its not that heavy but its also not as light as no space lol. I will be weighing stuff this weekend and will see. You could always take it off and see how it does and if you like it on, just bolt it back on. Only took 15 mims to take off.

    If weight is not your primary concern you could always just disconnect one of the endlinks at the track and leave the bar on. Same effect. I've thought about ditching my AC and come close to doing it but on hot days I'm glad I never did. I still drive the car on the street some.

    I took my links of last time I went to the track, the front end definitly came up better but there was no difference in my 60ft times. Now that I have the UMI drag bar on the rear I will be taking the front sway bar off.

    I have a lot of weight off of my car, but I drive the car 95% on the street, so things I did keep were:

    - Heat (A/C removed, but kept the heater core for those cold fall nights)
    - Front sway bar (curvy roads are fun too)
    - Stereo/speakers (exhaust gets boeing on the highway to and from work)

    I weighed in at 34xx lbs with a full tank and me inside, but then again, the 6-point cage adds a lot of weight.

    Removed Weight:
    Rear seats and seat belts
    Front seats (replaced with lighter seats)
    Front Seat Belts (replaced with 5-point harnesses)
    Spare Tire/Jack
    A/C compenents
    Power Steering (replaced with Manual Rack
    AIR/EGR
    Cast Iron Exhaust Manifolds (replaced by LTs)
    Catalytic Converters
    Complete Chromoly Suspension
    Weld Prostar Wheels and Tires (if you want to get technical for the track)
    All front accessories/pullies, except alternator
    ATI Crank Pulley w/o A/C belt provision
    Windshield Washer Tank
    Windshield Wipers and Motor Assembly

    Added Weight:
    Strut Tower Brace
    3-point Sub Frame Connectors
    6-point Roll Cage
    Moser 9" Rear (probably 100-150lbs over stock)
    3" Thick Radiator...not much heavier than stock, and I think the added cooling counteracts the little extra weight (180* in traffic during the summer is impressive)

    I'm sure there is more weight reduction/addition I'm forgetting, but that is the majority of mine.
