I pretty much have my car where I want it finally as far as power and handling mods go so now I am looking to put the icing on the cake by doing a little weight reduction. The things I have in mind are the rear seat delete, rear wiper delete, and a lighter battery. My car has the sunroof option and I rarely use it so is there a way to remove the motors and such from that to lighten it up a bit?

I am looking to do reversible changes to the car only but any thoughts and suggestions are welcome.

I have read several other threads on weight reduction but did not see anything about removing the sunroof internals so this is what I am mainly concerned about.

 

Hmm get rid of the heavy stock wheels that minis come with if you havent all ready. That alone will make the biggest difference. I went from the 21-22lb stockers to a 15lb wheel. So lost 20+ lbs of rolling weight.. that makes a HUGE difference.

 

CF boot and bonnet should save you like 30-50lbs

 

how much does it weight at the moment?

 

I have Tenzo-R type M 17x7 rims which are a few lbs lighter than stock. The carbon fiber bonnet and boot may be a little too much money at this point. And I don't know what it weighs but I am very curious. probably on the heavy side compared to some due to the sunroofs.

 

For comparison purposes, my car with only about 3-4 gallons of gas and no jack, weighed around 2,860.

I also have an auto which makes it a little bit heavier if I am not mistaken.

 

remove heated seats if you have that.

 

Quick and free weight savings:

Remove rear parcel shelf - few oz
Remove rear seats - several lbs
Remove toolkit - a few lbs
Keep the gas tank below 1/2 tank
Don't run with washer fluid in the tank

 

Wow. We had my car on a CAT Cert scale at work and I was 2650LBs with a 3/4 tank.

07 MCS. 6 SPD. Sunroofs.

 

My '07 MCS weighed in at 2570 with 3/4 of a tank. No options at all not even cruise control and rear seat delete. That was years ago though I'd really like to weigh it again, should be lighter now depending which wheels I have mounted.

 

you have no heated seats and no sunroofs? Interesting results.

Any idea on back seat weight?

I have been looking at a rear seat delete, deleting the b/s dampening, etc.

Nice weight though man I am jealous.

 

Why is the weight reduction required? Are you tracking or auto-crossing? If not, what's really the point? Just asking.

 

Wooo, big savings on the rear wiper delete!!!

Any need for weight reduction on the driver? I know that's a good spot for me to shave some pounds off my car.

 

Front seats... goood amount of weight!

 

I only weight 135 lbs so I think the driver weight isn't an issue. Haha

I have started to do autocross about once a month and go to the track when I can so that's why I want some weight savings. Especially up high to lower the CG hence the sunroof question.

 

I actually mean the seats, i almost got a good 60+lbs from changing my seats ;-)

 

How are the seats in your car? Have any pics, cost, etc? I may consider swapping mine

Awesome, Thanks.

 

Makes me miss the single piece seat I had in my previous car. Was impossible to get in and out of gracefully, but once in it was one of the most comfortable seats I've ever sat in, and it was awesome for autocross.

 

Just FYI MFSW would net you like a 2 maybe 3 oz gain in weight. I have no options with a rear seat delete but I replaced speakers and added an amp but, also went with a light weight battery. I am going to weigh mine when I get a chance to see where I am at compared to you.

 

Remove the doors and all the glass. It's a lot lighter. Harder to smoke though.

 

Yea I was just exaggerating the point that it has literally no options so it should have come out of the box just about as light as a second gen can be.

 

I recall seeing carbon fiber inserts that replaced the glass sun roofs. Trying to find the link now...

 

I did a quick search also, let me know what you find.
