RC F Weight Reduction
Hello All,
Please post any SPRUNG weight reduction tips you think will be useful. Obviously, reducing unsprung weight is a good approach, but then we start getting into parts that are quite expensive. Anyway, I believe the vehicle weight of 3,958lbs is with all fluids topped off, please correct me if I'm wrong. The goal is to drop 200lbs, quick.
I've ran my F at the track a few times, but never wanted to remove or reduce any weight from the vehicle until I felt it could run as quick as possible at "full weight". Now I'm exploring weight reduction and below is what I will be doing prior to my next track visit. My goal is to reduce weight as easily as possible. I don't want to spend more than 30 minutes on the process.
**Remove any items not bolted down from the trunk and interior, listed below:
Jack and Tools
Flat Repair Kit
Carpeted Trunk Mat
First Aid Kit
Cargo Net
Vehicle Manual
Front and Rear Mats
Engine Cover
**I weighed these items and they total about 40lbs.
Run the car with less than 1/4 tank of gas. I'm estimating this should save about 75-85lbs.
Empty out the windshield fluid reservoir, which holds over a gallon, should save 10lbs.
Remove the back seats. Now this is something I have not yet attempted, but will be doing so this week. Not sure how much the seats will weigh, but I'm guessing about 30-40lbs. If removing the seats alone takes me longer than 20 minutes I will probably not be repeating the process for each track visit.
These steps would easily shave about 150-175lbs. Please chime in with any other tips.

Hey bud, I live in Miami so PBIR is my 'go-to' since it is the only track within a reasonable distance. I was planning on heading up there on the 16th as well. Hopefully the weather is good and we'll see each other up there.

Titan cat-back exhaust will net you anywhere between ~30-40lbs depending on manufacturer...plus, it can give you a good bump in power as well
Aftermarket aluminum/light-weight suspension components can add up fairly quickly for weight reduction, too.
Swap out standard oem bolts/nuts for titan ones.
What you are stating/planning just sounds like too much work to keep doing before/after a race.
Like ROK is stating, our cars are agile elephants (aka Dumbo) so unless you are heavily modifying/putting lots of money into mods, it won't be as fast as the other guys out there on the track. Good luck!

if you are racing, take out all the seats, that's probably good for a couple hundred pounds the front seats are seriously heavy, get an aluminum racing seat and frame.
I know the front seats in my Camaro and my 300c were nearly 100 pounds each with the frames/motors/airbags/etc.

I forgot to mention my car has the A'PEXi non-resonated exhaust installed which saves 25lbs over stock. Removing everything except the rear seats takes less than a few minutes. The rest doesn't take me any time at all since all I have to do is make sure I arrive at the track with the right amount of fuel. My point is not to be faster than anyone else at the track, just want to see what kind of difference a couple hundred pounds would really make. I am on the hunt for lightweight wheels, but I want to be progressive in my approach. The right tires will also improve times. Another quick drop in weight would be replacing the oem seats with a lightweight option, but I LOVE the seats too much right now. I still might consider replacing those in the future if they dont wear well. Thanks for your suggestions.
