RHO Weight & Reduction Thread

[matt35hr]

Well pleasantly surprised at the massive difference in smoothness. The reduction in wheel weight makes it drive much better and the dampers control the tire much better.

I have the original wheels in the bed of the truck - I need to weigh them tonight.

Next up I’m going to 3D scan the brake rotors to drop some more weight next

I’ll check BCM programming in Witech to see if it has an option for Lithium batteries like we had in the Alfas. I have a Lithium battery from the QV I can use in the truck.

F=ma

Less weight improves acceleration in all directions. It seems to have dramatically improved the effectiveness of the dampers. Would recommend.

Love it! This is the way.
Don't mind the trolls.

Some people like to modify there trucks to realize an actual difference in performance,weight reduction is the preferred method as opposed to throwing a "tuning module" on the truck that could destroy the motor or void the warranty.some people like to throw rubber covers over there existing tow hooks...
I love what's he's doing and plan on doing a very similar mod list when I receive my truck, that said, to each there own.

I understand why someone does that but thank you for the explanation. Maybe you haven’t seen my other cars or what I’ve built. I’m sure it will help the less educated understand.

Generally speaking I would start with something lighter but appreciate your snarky comments lol. Good luck to you and as noted to each their own. I’ll share my opinion as well as anyone can with the mods I do.

Have a great day and look forward to your mods once you get your Ram too.

Definitely NOT offroad. He's going for SPEED.

Agree,although I'm sure those volks could handle some serious offroading,
Full compression landings...

Just a little ribbing among fellas
Didn't mean to go to hard
I was on x(twitter)this morning...

lol no worries. Hence my smile n lol.

Those Volks are beautiful works of art that just happen to be forged aluminum & some of the highest quality wheels you can buy, love them, well done!

All i can think is......

She's all alone
All alone in her time of need
Because he's racing and pacing and plotting the course
He's fighting and biting and riding on his horse
He's going the distance

I’ll have to take another picture as you can just faintly see the weight. I took 3, the scale display frequency timed my photo perfectly. But the OEM non headlock wheels are 31lbs 0 ounces ( granted this is with wheel weights, center cap, and valve stem.). So maybe 30.X pounds for the factory wheel. So that’s a solid 11-12 pounds per corner with the volks. . Big gains.

 

[Cautionary Tale]

Lighter wheels and brakes put less stress on all the other components of the suspension and driveline,not to mention removing unsprung weight(wheels, tires, brakes) taking 4 pounds off in actuality will feel like you removed 16 pounds, the vehicle will start to feel more nimble and acceleration numbers will drop

I wish I kept my Z, miss my Sparco seats, Volks and autocross but 2 seater and kids were problematic. I stripped mine down bare and definitely noticeable 360 degree difference in vehicle drive characteristics.

@IdealRace ..I know I ask hard questions for a 6k lb plus truck…

funny thing though today, my wife n I were heading to a state park and a chick in an Ineos, thought she was it. Light turned green and I realized she was flooring it when I was about 1/2 way down , I wasn’t losing her and then put it to the floor.

Walked her bad. Not unexpected, but fun and then my wife asked if I thought she was racing us…it was painfully obvious from my perspective…200 or so hp corrects things

OEM Battery 52 pounds 13 ounces

Antigravity Battery 15 pounds 13 ounces

37 pounds of weight loss. There is the aux battery too...

Rear tow straps for pulling other people out. Directly behind these are holes for strapping the truck down - if they couldn't strap to a frame rail or the rear axle.

6 pounds 13 ounces per side. 13 pounds 10oz total for rear.

The Jack kit under the passeger seat weighs 8lbs 15oz.

Front plate holder - 10oz

So far wheels - 11lbs x 4 = 44lbs
battery - 37lbs
rear tow points - 13lbs 10oz
Jack kit - 8lbs 15oz
Front plate - 10oz
Total - 104 pounds 3oz.

I removed the mud flaps which I added - so we'll just not count those. They were 1 pound a piece.

Just barely fits in the dyno bay. I need a some different jacks that have more stroke. Turns out the jacking point on the front is the front lower control arm (FLCA) which I find odd, but maybe very reasonable especially if the front suspension has a TON of droop. I have my eyes on several components that I think could be quite a bit lighter - but we'll start with things we can remove and then move to things that can be lightened.

Well they say every 100lbs is worth a 1/10th of a second in the quarter.

Maybe I missed it did you pop the spare off too?

Not yet - I have to assembly the spare tire removal tool and drop it. Looks like there is a plastic surround that I can remove as well. I'll get to weigh the complete wheel/tire assembly and then back calculate the tire weight. Tirerack says its 62 pounds. So if we're 31&62 = we're 93 pounds without the tire retention hardware & surround w/hardware. So I suspect it'll be near 100 pounds all in.

 

[IdealRace]

96 pounds 1oz. Which means the tire is closer to 64/65 pounds.

200lbs 4oz. As of now.

 

[RAM-Ranch-MT]

heck yeah man. i applaud your pursuit of lightness. LOL. cant wait to see what this thing puts down for power with your tune and all the stripped weight. badass. 0-60 gonna be nuts.

 

[IdealRace]

Rear tire winch assembly. 4lbs. 7 ounces

For a total of 204lbs 11oz.

Working on 2 piece brake rotors. Scanning rotors, pads, and then installed rotors/pads/calipers. 30mm wide front rotors are odd. 9mm wide internal straight vane and fed from the wheel side. There is plenty of room on the upright for a brake duct/guide on the inside. Not sure why they opted to pump air from the face of the wheel through the rotor. Good question for the engineers!

I think a 32mm curved vane rotor with an aluminum hat ought to save weight and be a significant improvement on the rotor itself.
