So I decided to roll through a closed truck stop on the way to fill up this morning, my car had nothing in it besides about 1.5 gallons of fuel, it weighed in at 3640. I've got a few mods now and plan to do more but I really think sub 3600 will be a stretch to achieve.

 

CC rotors wil easily get you there if you have the $. So would a set of Brides or Sparco seats.

 

I got figs 2pc rotors all around, seats are in mind which would put me sub 3600 for sure.

 

Get rid off the Spare tire, if u drive local...

 

That was the first thing to go after I brought the car home, I got towing on my insurance and my old car as a back up if there is any problems.

 

Why dont you list your mods to give people here a clue and a reference. This thread is useless to anyone wanting to drop weight if you don't mention what you have done to your ISF.

 

Rule of thumb; Every 100 lbs equals 1/10th time off. I'm curious what you guys are doing for weight reduction. Seems like other than spare, lighter rims possibly- what else is there?
Pulling seats would be the other big weight loss.

The above thread is a good refference to use but I started this to see what other people have managed to accomplish on their builds.
My car is a 08 ML sound system car with a sunroof. I have a Joez exhaust w/ jic magic titanium mufflers, figs rotors all corners, carbon driveshaft (only weight difference is the removal of oem mounting hardware, guibo's and bolts for stock driveshaft), local made aluminum rear subframe braces (subframe brace air guides removed), spare tire/jack/tool kit removed, volk gt7 19's.

Next I will be installing a full cwest eld kit, doing full figs bushings/links/control arms, tokico hts shocks/swift springs, sikky swaybars, tom's chassis bracing and fabricate lighter (carbon) under fairings, maybe Seibon trunk/front fenders (painted of course)

 

Currently my weight reduction items are:
removed jack and tools – 8.75 lbs
removed trunk mat – 4.5 lbs
removed spare tire – 37 lbs
Borla catback exhaust - 16 lbs
BC coilovers - 10 lbs
Total: - 76.25 lbs

I need new rotors and I have a set of Enkei wheels in the basement, just have to buy rubber.
Coming soon:
Enkei PF01 18x9.5 - 16.5 lbs rotational
275/35R18 Michelin PSS - 2 lbs rotational (good bye understeer)
FIGS 2pc rotors - 23 lbs rotational
Total: - 40.5 lbs rotational

Combined Total: -116.75 lbs

At some point I may get a lighter battery, light weight front seats, and have a shop remove the sunroof and replace it with a reinforced aluminum section. I'm guessing those three things combined would net 150 more lbs.

 

Just ordered up the Braille b3121 on Amazon for $243 with battery holder & prime shipping (battery delivered Monday, holder on Tuesday). This is the 21Lb battery

 

Let me know when you get the Tokico HTS shocks and springs in. My car is due for new struts soon and I'm leaning towards the 2013 shocks/springs. I haven't found much info on the Tokico shocks for the ISF. Seems like they're made for the IS250/350

 

Here ha go:

Do you have a link or thread about the carbon driveshaft and it's benefits for the F, or maybe some pics?

Thx

 

Nice moves
