Now keep in mind this is my daily driver cause its my only car and i drive it everyday. I can put up with almost anything in the sake of making my car faster and lighter.
BMR mild steel K member (i got this for free cause it was broken i probably added maybe 5 lbs of reinfocement steel so its safe to jack the car up from the k membe and it will never break again)
PA mild stel lower control arms
HAL's all the way around
Chromoly adj rod end real LCAs
8.8 has a spool and 31 spline axles
No exhaust just a bullet on the end of each header
No A/C or heat (and all related wiring)
No power steering (and all related lines and cooler)
No radio (and all realted wiring, speakers, amp and antenna)
Removed cruise control and traction control (and all realted wiring, cables and pcms)
No bumper supports (cut off the big *** part of the frame that the front bumper support bolts to)
Cut off the front metal "sub fenders"
Chopped up the bottom radiator support and the support that the air box bolts to.
Chopped up the lower air box (i remounted the air box)
Chopped up the alternator bracket (getting rid of the idler pulley)
Took a 3" hole saw to the front portion of my frame (only from where the k member bolt to forward)
No ABS (and al related wired pcms, wiring, sensors and lines)
Cut out ALL mounting tabs that were no longer in use (like the raer seat brackest rear seat belt brakets, antenna bracket pretty buch anything spot welded to the car)
removed all under car heat shields (along with all spot welded mounting tabs)
replace heavy M6 cross member with a custom th350 cross member
i run a 8" converter
Areospace "drag use only" front brakes
No fog lights (and all related wiring)
No air bags (and all related wiring, sensors and pcms)
installed a Grant steering wheel
Running a Hawker/Oddesy 12 lb battery
Replaced the stock over flow tank with a lightweight Summit one
Took uot both door bars
Have SUPER light weight carpet (thin layer of fleece from the fabric store)
Have two Kirkey seats with custom aluminum mounting brackets
Removed center console
5 point chromoly WELD IN roll bar (i won't be going fast enuff for a 10 point, a 5 point is whats required not a 6 point, and weld in is a bit lighter than bolt in)
I think thats it
I could make it lighter by running justone Kirkey seat, taking out my four stock floor mats, removing all my interior panels, windshield wipers, horn, e brake, switching to manual brakes, window motors and stuff like that. But this is my daily and i wanted it to be light but still look good inside.
What i have planned for more weight savings is
Swiss cheesing my Kirkey seats
Pin on hood
Installing Speedglass lexan windshield and rear hatch glass (might go with pin on hatch but not sure since i put my slicks in the back when i drive to the track)
3" hole saw the deck that the dash bolts to
Chop up my stock metal tank or maybe replace with a plastic one
Replace my mildsteel k member and a arms with chromoly
Replace my modified mild steel BMR shorty torque arm with the chromoly version
Rear Areospace brakes
Replace Weld rims with lighter Bogarts
I'm hoping to get the car around 2800 raceweight and still daily drive it. BTW i myself weigh in at about 190 lbs.

Its alot of compromise to get the car that light.
Mine is around 3100 and I still have a stock looking interior.
I did delete the E brake, horns, air bags, cruise control, and a bunch of other stuff.
I have only 1 seat but all the plastics and lightweight carpet are in it.
It sure makes a difference in how the car performs though.
drop 300 pounds off the car and WOW.

I figure I'll pull the A/C since it doesn't work anyhow, add a fiberglass ram air hood, aluminum driveshaft, dry cell battery relocated to the rear, rip out the stock carpet and insulation and lay light weigh carpeting down, racing seats and possibly replace the glass with Percy's Speed Glass. Replacing the glass alone should drop near 200lbs from my car. That's about 340lbs there. 400lbs total if you include the "work" I've already done. That'd put me at 3060lbs with me in it
I just took out the Back Seats and the AC, and I haven't weighed it at all. I bet I gained it all back with the Eibach Springs and LS1 Brakes, they weigh a bit more than stock.
