Car will gain some weight with some aero additions I have.

I'm going to document the weight reduction strategy I move forward with. I want to sacrifice no comfort, so radio, ac, etc all stays. This won't be a "traditional" weight reduction scheme. So, I will document it here, moving forward. I've done extensive projects like this in the past, using various techniques. Corvette is challenging due to the space frame construction, so I am going to explore a bit.

As a side note, my gf just bought her first Corvette, a 2009 6spd base model. 1/2 tank, her car weighed in at 3189.

How about seats? Not all aftermarkets are lighter but there are definitely some LB's to drop there.

Seats would be a traditional method, but yes, seats are a must. I had some seats for it, but I sold them as I decided I wanted something a little more comfortable than a dedicated track seat. I want a combo of support, but with comforat and ingress/egress...with a sub requirement of affordability. I have some ideas, and fabricating seats from scratch is one of them. I have 70ft of heavy twill carbon...I may. I've made custom seats in the past.

It will come down to time vs cost for me...whichever I have more available at that stage.

The headers and x pipe make a huge difference in weight. I dropped quite a bit doing the full exhaust, although unless you go with straight pipes its going to be hard pressed to get an axle back lighter than the stock one. Keep us posted on your weight loss journey!

Side note, your girlfriend drives a 6 speed LS3 car? She single?

This'll be a fun post to watch.
There's another post here somewhere about stages of weight reduction, will try to find it.
I have also considered DIY seats, but will likely buy something already made one day.
As for weight, for 2 reasons IMO, you should weigh with a full tank. 1; it's standard weigh-in procedure, keep apples to apples compared to other cars. 2; how much exactly is a 1/4 tank, a few gallons +/- weighs quite a bit, hard to get a proper baseline and consistent numbers.

Wow, wonder how light mine is with 1/4 tank. Your aftermarket wheels, c6z brakes and cat back have to add more weight over stock.

grantv

3/4 tank should be around 85# or so, full tank around 115#

This was mine with a full tank no one in it.

btw mine has sound deadening and two 8 inch corner subs in fiberglass enclosures from Vettenutts and a double din with aftermarket speakers...

MVR 155

Mine was 3060lbs with just shy of 1/4 tank of fuel.

I'll have to weigh mine now next time I'm at the track. Mine has stock wheels, the LT's and x pipe should drop some weight, those stock manifolds and x pipe were heavy.

You should throw done Rival S tires on it and autocross it in the SCCA CAM-S class and hang with a bunch of kool guys and gals. It'll be the most fun anyone can have with their clothes on.

It wasn't much of a comparison. I just weighed them as they sat, the day I was in the shop and said....I think I'll weigh them, I'm bored...

KnightDriveTV

I do my best but....there's never any guarantees she won't throw me in the trash can...lol.

She loves it though...says its everything she has ever wanted from a car. She's had a good number of modded cars over the years that I put together with her.

BB bullets are pretty basic, not much to them. I'm pretty sure they are just about same weight as the Ti's. I definitely put some pounds on with the brakes, though the suspension is a weight saver. A lot of give and take on my car. I was pretty happy with the weight when I saw it.

I'm about to get to it shortly. I am fabbin up some pad levelers here shortly, with rolloff area. Want to get everything all level, weighed and then start moving forward. I'm going to be adding some weight to the car with aero, but I'm looking to drop some key pounds. I also realized i have bunch of crap in the trunk when I weighed it, so it's under 3k.

My 2002 Z06 set up for autocross in SSP class. 3158 lbs with full tank. nothing removed from interior yet, changed seats to Corbeau Sprtline Evolution X. & Shark Bar harness setup, Lg 1.75 long tube headers & X-pipe, no CATS, Borla S-Type exhaust, stock brake calipers, added a 10" tall aluminum spoiler, 10.5 x 18 Speedline wheels with 315-30 Hoosier A7's at all four corners . Delrin suspension bushings, hollow sway bars, Koni yellow sport shocks, AGM OEM size battery.
I know there is weight savings to be found within the rules and at some point I will begin to take advantage off all I can.
At 260 lbs the most to be saved would be for me to go on a diet!

At my work we've made a number of snowmobile tunnels for a company that mods them. It sheds a few # from each sled. I always figured similar, stop eating McDonald's for a week and save $500.

Georgies

Who the hell still eats Mcdicks?

grantv

I just looked it up; 75 hamburgers per second, so plenty.
I think you know that's not the gist though; go on a diet and save $500, is that better? The point is $500 (or maybe it's $800?) is a fair bit of loot to cut IIRC 8#

I'm to 242 (6'2"), and I"m aiming for 210 in the next two months. So, that is on the table and being focused on...lol.
