So, what will a decently gutted (no A/C, etc) but street driven 4th gen weigh?

 

You have to cut them apart and install a block-off plate over the hole in the firewall. There are a couple of threads going about this.

Here's one of them:
https://ls1tech.com/forums/lt1-lt4-modifications/711439-c-firewall-stuff-removal.html

 

Our Bogart wheel weights are not accurate. Depending how we build them affects the weights. A 3.5" front runner can be as low as 6.75lbs, rear as low as 9.5lbs. Weights are dependant on the sytle, series used and how they are put together. The typical F-body design has a front at ~9lbs, ~10lb if we are building them to OEM specifications.

you can shorten this post if you like...figured I'd add a bit of info for explaination.

 

Here are the photo's of me doing the LS1 heater box I put in My 95 Z28

 

Saved 35lbs on the fronts and 31.5lbs on the back. 12lbs for the parking brake.

 

I have a huge list of weights or weight reduction of atleast half of the weight reduction I have done, but I will need to find it. Here is a couple from the last couple days though.

9.8 Wipers/Motor
8 Hood Latch/Brackets
30 Sunoco Bolt-on
6.2 Dash Brace(steel piece)
12.6 Plastic/Insulation on Firewall
2.2 Visors

I will be weighing the kirkey drag seats tomorrow before/after the swiss cheese.

today i removed the side impact bars.....

i also removed the back bracket for it where the 15mm nut is (where the door lock mechanism is) that weighed 2.75lbs. so for both they weighed 5.5lbs if you wanted to add that as well

i lost 22lbs total today from both doors

-brandon

im debating of taking the wiper motors out as well....and just making sure i have my windshield waxed at all times in case of rain....but im not sure yet

 

whats a set of 3.5 x15 and 10x15 prostars weigh? no tires.

Chad

 

10lbs each for the 15x3.5s

I read on here that 15x8s are 13lbs, so I would imagine that the 10s would be 1-2 lbs heavier

 

thanks

so we'll say the 15x10's are 15 pounds a piece = 30 pounds.

+ 20 for the fronts = 50 for wheels.

what are stock 17x9.5's? 40 a piece?

so thats 160 in wheels.

slicks weight 25 pounds? so 50 for 2 slicks

skinnies are light as **** 20 pounds for both?

so 120 pounds for skinnies and slicks compared to what stock?

200 +?

whats the savings going from 275/40/17's on 17x9.5 z06 rims all the way around to 3.5 skinnies and 10" slick?

Chad

 

did the math myself...skinnies up front are 17 a piece 275 DR's are 26 a piece + the 70 in wheels = 155lb.

275's on all 4 corners = 104 lb.

17x9.5 OE concept Z06's are 26 pounds a piece. = 208 total

208-155 = 53 pounds rotational weight.

Chad

 

I'll add in what I've done so far to my 93 Z28:

Front Bumper Support = 25.375 lbs
Fog lights and brackets = 4.0625 lbs
Cruise control, cable, and throttle cable cover = 4.4375 lbs
Air pump and brass fittings = 5.9375 lbs
Stock horns = 1.875 lbs
Stupid siren and loud horn = 2.5 lbs (Ignore)
Stock Y pipe and single cat = 21.1875 lbs

 

Close to 50 on the LT cars because of the difference in spindles and the amount you have to cut to get the brakes to fit.

Strange front brakes= -40.9 lbs.
Cut LH spindle= -3.83 lbs.
Cut RH spindle= -3.69 lbs.
Total savings in front brakes= -48.42

Old rear brakes= 23.10 lbs. each
Wilwood race brakes= 11.37 lbs. each
Total savings in rear brakes= -23.46 lbs.

 

Door panels for the Trans Am are 9 lbs. a piece. I just pulled & weighed mine.
(I'm keeping the arm rests and covering the rest of the door in either aluminum or vacuforming plastic)

 

thats an interesting route....keep me posted on how it comes out

-brandon

 

You're a poet...and didn't know it.

 

i got my side impact bars loose but how do i get them out of the door?

 

cut them with a sawzaw!!
