2600# without ballast. 150 lbs ballast required to meet minimum weight (2750#)for class.

That's with stock glass and the mods in my sig. Also hood and trunk are fiberglass. Hood weighs 22 lbs and trunk 12 lbs. Also 5 gal fuel cell in the trunk, full. This is a coupe though not a hatchback. But I think you can easily shed 100# changing to fiberglass hood / hatch.

 

2780lbs without driver when the car was gutted with a six point roll bar and the stock dash gutted.
Now I have a NASA legal cage, aluminum dash, gutted all unnecessary wiring, lexan windshield. I'm hoping for under 2850lbs without driver. My fiberglass hood is about 18lbs, I think the stock one is 40lbs.

Edit: I just got off the phone with the electrical shop. All the unnecessary wiring weighed in at 40lbs, and the majority of that is high and from the dash forward.

 

2970 with half a tank and an Ultrashield seat, without me. No A/C, smog pump, back seat or sound deadening. Stock hood, sub-frame connectors, harness bar, torque arm and panhard bar. I've since removed the passenger seat. Still have all the speakers, wiring, dash, etc. This is on a 92 notchback. Whenever I decide to convert the car fully to CMC2 or AI, I am going to gut the piss out of it.

 

That is pretty good for a car you can still drive fairly comfortably on the street............well in the winter.

 

89 Hatch, ex NASA CMC car with full road race cage. With drivers seat only it is 2848 with no fuel, no driver. No glass in doors, rest is stock glass.

 

What heads are you guys running? iron or aluminum

 

89 Fox AI racecar... fiberglass hood, hatch. Glass windshield, lexan elsewhere. Aluminum headed BOSS block, T5, 8.8 rear. Full cage, fire system, accusump, coolsuit, 15gal cell. #3120 lbs w/ driver and 1/4 fuel.

 

Sam, are ya'll shooting for 2700 WITH cage or WITHOUT cage?

Mark

 

With....eventually. It won't be immediately, it costs good money to lose weight lol. We have PLENTY of spots to drop weight, just costs money..

Geez, you guys are making me feel like I drive a pig. Full stock 1990 GT (hatch) with everything in place and a full tank came to 3300lbs without me in it.

 

My 82GT which started life as a light weight factory A/C delete car and no options is currently at 3090-lbs. That's with full interior minus rear seat and rear carpet, and a 351W.

 

92 LX Road Racer, GT40 Irons, stock K member, Panhard bar, Subframes and Autopower bolt in Cage (upgrading to Custom). 1 Kirkey seat and rewired with bare essentials.

Fibreglass hood, stock hatch and stock glass all around. Heater/Blower etc removed. With 3/4 tank of gas and me (233lbs) in it the car weighs in at 2992lbs. I have a set of aluminum heads to go on so that should save another #50 or so.

 

'91 GT, 2,900 lbs w/no driver

Everyones' Fox Body? Millions of pounds.

 

2860 aluminum heads mildly stripped interior.

 

Get a structural engineer to do an analysis on the car and they will remove tons of weight without compromising structural integrity.

Oh wait.... this is a FOX..... Structural integrity wasnt around when those were made. :rofl: J/k

Car is coming along nice!

 

89GT,

Exactly 3100 without driver, fiberglass hood, full interior, MM Full Length SC, MM P/B, MM T/A, MM LCA, Griggs K.Member with Griggs Coilvovers, M-2300-K, Cobra R 17x9 wheels, Mini torque starter, 130amp alternator, 9 to 10 gal of gas and stock motor.

 

Bringing it back!!!
Put my 89 notch on scales last night. Race ready with driglites on, passenger seat removed and almost a full tank of gas. It came in at 2689lbs w/o driver and 2900lbs w driver. 56% front 44% rear. Best part about that is it still has all the front interior, tilt steering, power mirrors, power windows, power locks, factory glass and doors.

Future plans are optic armor glass front and rear, Holcomb steering column, gun drilled axles, Kirkey race seat, carbon fiber rear quarter windows and a bunch of race craft titanium bolts, 99 gt aluminum dual piston calipers and what ever else i can find to shed weight.

3000lbs with me in it,
car is gutted

shooting for sub 2800lbs

 

When I had an opportunity to have it corner weighed at a SAAC event a number of years ago, my 86 coupe weighed in at 3,120 lbs with fluids but no driver. The car has a 56.6%/43.4% front to rear weight distribution, and the cross weights are surprisingly good (basically 50/50) considering I haven't had it corner-balanced. Corner weights are as follows:

FL = 887 / FR = 899
RL = 675 / RR = 659

My car is driven daily, so it has almost a full interior (roll-up windows and no center console) and a basic stereo system, which includes a Pioneer deck, 6.5" coaxials in the doors, and 6" x 9" speakers in the rear deck. I also had sound insulation installed on the floor, from the pedals to the back seat.

It has controls for A/C but currently does not have the equipment installed, and I'm sure my seats are lighter than the factory seats, so that's all saved a few pounds. Suspension-wise, upgraded components (front coil-overs, k-member, control arms) have also saved a bit of weight, but the weight will increase when I get the $$$ together to add a torque arm to the mix.

 

That's so 2010 hehe. Yanked the heater core and all behind-dash plumbing, cut up most of the hood support, added tow hitch. See below for weight with 3/4 or more of a tank of gas at Devens Champ Tour earlier this year. 16*12s with Hoosier bias ply tires.

Oh, and I wouldn't say I could comfortably drive it on the street. It's registered and inspected, but far from comfy (no A/C, no heater, speakers, radio, sound deadening; the harness is a pain in the ass, PM3L with heim joint/spherical bearing, etc.). I mainly drive it to events and maybe a few parts runs these days.

Weight is the mind killer.

(they had the scale's wires backwards)

Just weighed it today and it came in at 2900 lbs. w/ 3/4 of a tank of gas, 3040 with me in it (I'm 5'2" 140 lbs), although I've subtracted the amount of pounds each item was from the original factory advertised curb weight of 3150 and got 2887, which is pretty close to the number I got on the scale.

 

Anybody got the money for carbon fiber wheels?

I think they actually weigh negative numbers, and will blow away with the wind if not held down............well, maybe not that light.
