So, I was bored and trying to put off other projects I have piled up so I took the time to weigh a few of the easy pieces to take off for a track day. I used a sensitive baby scale that is accurate to 0.5 oz.

Easy track day weight reduction:
- 10 oz (0.625 lbs) - 1st aid kit
- 5.5 oz (0.34375 lbs) - Cargo net
- 4 lbs 11 oz (4.6875 lbs) - Trunk mat
- 2 lbs 8.5 oz (2.53125 lbs) – spare tire floor cover
- 8 lbs 12 oz (8.75 lbs) – Jack and tools
- 37 lbs 11.5 oz (37.71875 lbs)- Spare tire, spare tire screw, & two foam inserts (HEAVY AS HELL)
- 11 oz (0.6875 lbs) – D.S. trunk plastic tray that carries first aid kit
- 8 oz (0.5 lbs) – P.S. trunk plastic tray that covers Amp
- 1 oz (0.0625 lbs) – 3 plastic caps in truck
- 2 lbs 1 oz (2.0625 lbs) – both back seat floor mats
- 2 lbs 3 oz (2.1875 lbs) - P.S. floor mat
- 1 lb 15 oz (1.9375 lbs) – D.S. floor mat
- 3 lbs 11.5 oz (3.71875 lbs) – Engine cover
- 1 oz (0.0625 lbs) – cigarette lighter coil ()
- TOTAL: -66 lbs (rounded)

Add that to the weight savings that can be found below (on my to do list):
- FIGS 2pc front rotors (-14 lbs rotational)
- FIGS 2pc rear rotors (-9 lbs rotational)
- BC coilovers (-10 lbs)
- BC Forged RS40 wheels (18x9.5 +45 & 18x11 +60) (-24 lbs rotational)
- 275/35R18 & 285/35R18 Michelin PSS (+ 4 lbs rotational +50mm front & +30mm rear tire width)
Borla Catback exhaust (-16 lbs +20whp) (already done)
Odyssey PC680T battery (-26.5 lbs)
Mods Total: -95.5 lbs (-43 lbs rotational mass)

Total with planned Mods & track day parts removal = approx -161.5 lbs (-43lbs rotational mass)

FYI, I just ordered a set of 10mm wheel spacers. I am going to take my 275/30R19 PSS tires with19x9 +55 rear wheels and mount them on the front with those spacers. This will essentially make it a 19x9 +45 wheel in front. I will drive around to see if a 275/30R19 (same size as 275/35R18) will fit in front with a +45 offset. if it doesn't, I will get 255/40R18 tires instead of 275/35R18. I think it might just fit though, since the 275mm sizes are 0.5" shorter than stock, which should give it a little additional clearance.

oooo windshield wiper fluid, genius!

What about the factory sub/amp? Easy enough to get to and remove without adverse side effects?

Does anyone know how much the stock suspension weight? I remember seeing a thread that had the weight of the stock suspension and the BC racing coilovers but I can't find it.

Most of the owners are forgetting the #1 on the list of weight saving are the drivers themselves lolz . That is the most important leaner, healthier, stamina, physically and mentally are ready for any kind of racing lolz

bc coils save a total weight of 10 lbs over stock

juanmedina

For my 2010 F, the fronts weighed in at 14 lbs each side and 15.5 lbs in the back. The BC Coils w/ swift springs came in at 10.5 lbs, all around. The total savings ended up at 17 lbs.
