Martian Wheels MW03 - New discussion thread

[LoL-Gas]

So 4 more lbs for 1 inch of width? Interesting.

From the pics it looks like they didn’t put the step hub lip in for P rotors. Make sure the wheel sits flush against the rotor hat or that’s no bueno and a safety issue.

Oh Martian Martian Martian….

Is this it?

Is this it?

That is the correct hub if that’s yours. I was trying to quote @comp3mo pic but it didn’t attach it.

They should just add the step lip to all their wheels like other manufacturers do. Resell would be a hell of a lot easier too.

All mounted and ready for the drag strip next week. I was consistently getting high 7.20's with the Uberturbines so I'm hoping dropping 9lbs per corner is enough for 7.10's.

The difference between 20s and 19s might not be as much as 20s to 18s. It would be really impressive to get into the 7.1x 1/8 mile times with those wheels and no interior weight reductions. What tires did you go with?

Definitely let us know how the track day goes. Curious to see how these 19s perform. They look great.

Here are my 3 best 1/8th mile passes. First one is stock with 20” UberHeavies. Second is Stock weight but with 18” T Sportline wheels. Third is minus ~155 lbs interior weight and 18” wheels.

I am curious to see how your times line up with these.

Stock on 20” wheels

Stock weight except for 18” wheels

Minus 155 lbs and 18” wheels

Did Martian update the weights on their website? All of the values are different than when I checked them earlier this year for the same wheels.

Their 18x8.0 MW05 “FORGED” wheel is listed as weighing 22.5 lbs now. That said something like 17-18 lbs before for an 18x8 Model 3 wheel.

22.5 lbs for 18x8.0 fully forged is not good at all. My 18x8.5 flow formed wheels weigh 22 lbs. The stock Model 3 18” wheels weigh a little less than that too.

It appears that the wheel weights have changed again on their site. The 18x8.0 wheels are now listed at 19 lbs with a 1,609 load rating.

When I took the screenshot the other day it said 22.5 lbs and a much higher 2,204 load rating.

I don’t know why they keep changing the specs drastically. The car doesn’t need the 2,204 load rating and those wheels appear to be quite heavy if they are truly “forged”.

Hopefully, they explain what the differences are.

And that’s why I keep on telling everyone how shady this company is. The design has not changed ever since released. They aren’t even a vendor on this site.

Update:
I was able to get 4 runs in but they closed the track due to wetness. It rained during the day and it was extra humid in the evening. Everyone was complaining about traction.

Current car setup: 19" Martians 8-9lbs below the stock wheels with the Pilot Sport 4S tires. That helps offset my 40lb stealth hitch. Weight is stock otherwise.

I broke out my times based on date below and I break it out by lane because the Right is noticably faster. My Oct 21st trip was when I started preconditioned the battery between runs and it seems to help the 60ft the most.

I did the preconditioning also last night and I was able to get down to 7.23 twice. The 60ft was almost unchanged though so I'm hoping a dry track will get me down closer to 7.20 next time.

Great job! Those are strong times especially with the extra hitch weight.

Preconditioning actually has very little impact on 60 foot. It really doesn’t start helping until after 40 mph. The attached graph shows how low “Max Discharge” values start to separate after 40 mph but not much before that.

Static and rotational mass is what affects 60 foot the most. I ran something like 30+ passes at 1.79-1.81 for 60 foot until I dropped the 155 lbs of weight. That took it down to 1.75 according to Dragy and 1.725 according to the track slip.

However, at 40-60 mph is where the real benefit to dropping the weight happened.

Reducing mass is less affective when torque is lower which happens at higher speeds.

If you want to get below 7.20 then you have to reduce static mass. Start pulling seats. It really isn’t hard if you know what to do. I can walk you through it if you decide to do it. Front passenger seatbelt is actually the hardest part.

Preconditioning helps the most with Trap speed. Monitoring those temperatures and launching when “Max Discharge” was at the highest value is what allowed my car to be so much faster than every other one. Well, that and the ideal decline for the slope.

Your times are better than mine by a couple of hundredths with similar setups. If you remove the static weight you could definitely get all of the best times through the 1/8. I would love to see someone go 7.10.

Martian came out with 18x8.0 mw05's. The weight is about the same as a Titan 18x8.5. Advantage for martian are the slimmer tires you can put on. For me these would be winter tires for next winter if I decide to go that route. If my beater car lasts, I will just continue to use that.

With their past known history of playing deception on ship dates.., I wouldnt be surprised they been selling flow forged wheels disguised as fully forged..can anyone confirm if martian wheels are indeed fully forged?

This is not big of a difference.., I dont know if its worth shelling out ~3.5k to replace oem uberheavies
