Lug nuts for RFP1s

[Yarflana]

Since I am looking to go with lighter weight wheels with the RFP1s (cutting 5 lbs a wheel), I am also looking to go with the best lug nuts I should in terms of weight and strength with keeping with the idea of shedding weight at the wheels.

They must have a wheel lock key vs. all the nuts using a 19mm (or whatever size) socket.

Any thoughts?

Thanks,
Pat

Yep. Go to God Win racing (Mazda) and see what they sell. I got a set of those that require the special tool. Love them.

Klink10, I got it from your garage, so no need to PM me back. Thanks for all the help.

I would not use Muteki whatever you do, I recently bought a set of those for my Kosei K1's and they blow

Lots of choices on my shelf and on my site. I use two-piece Rays.

Care to elaborate why they suck? Just curious.

i use mcgard spline drives and i'm quite happy with em

If you want light weight go with the Volk Raicing duraluminum. The lock nut is a odd shaped seven sided nut.

Ok here's the deal...finally got the RFP1s and they are the bomb like I imagined...pics to come soon.

I have the chrome steel lugs from Discount Tire with a spline drive key for each lug on all wheels.

I am curious whether spending $50-$100 to change to McGard or Volk steel (not going to aluminum) is really going to save me much in weight at all? I mainly daily drive, but want to have less weight, where I can make the most difference (i.e. wheels (already did that), battery, take stuff out of the car, pulley, take stuff out of the car, me lose weight, etc...).

Additional thoughts are appreciated.

I had one of those aluminum lug nuts break on me, and I had to get the lug nut and lug blowtorched off my wheel. Get some wheel locks to keep those bad boiz on. I have these gorilla lug nuts that serve as wheel locks as well. U cant just use a key from similar lug nuts to take these off.

[Yarflana]

@marlondog - actually, what Discount Tire gave me was a full set of Gorilla's, now that I looked at the key in my glove compartment.

I think I will leave well enough alone and not mess with replacing the lug nuts. They cannot make that much of a difference weight wise, especially since they are close to the center of the wheel.

You're not going to feel the difference in weight from lugs.
Just get a good quality set.

I've used Muteki's for a couple years now on my Echo, and even through an entire season of swapping street for race tires at the track, they still look good and more importantly the threads are still good. Splines are in great shape.
I can't not recommend Muteki's - unless their quality has gone down.

I've used Gorilla's with good success too.

Been using mine for almost 8 years now on my '05. They are lighter than the steel ones for sure but you aren't going to notice any difference driving.

there was a post on nasioc about light weight lugnuts, let me see if I can find it

Ray's lightweight lugs weigh just over 20 grams each. Stock units are about 60 grams each. So that's 150 grams saved, per wheel.

If you do the math, with 5x100 lugs on a 17" wheel, saving 150 grams at the hub is the mathematical equivalent of saving 8.3 grams at the drum of the wheel. With a 225/45/17 tire, 8.3 grams of rubber is contained in .1mm of tread, which is about half the thickness of a human hair.

So, in summary, you save more rotational inertia doing a powerslide and burning off a little rubber than you do by spending $150 on lugnuts.

[Yarflana]

Yeah, based on that logic, you should have lighter weight each day, but I would venture to guess it would be easy to offset that gain by filling up the gas tank.

[NJ Drive]

His calculations are off... 150g at 100mm from center would be equal to 23.642g at the outer tread surface of a 225/45/17 tire with a 24.9785" diameter. Still minimal though.

The coatings they use just fade and or totally disinigrate within weeks, and overall have a very cheap feel
