Just wondering if anyone has used these wheel adapters before?

They seem tempting, but I don't understand how these could possible be strong enough.

lot of people use them. porsche's been using big *** spacers for decades.

Hey Aux,
Thanks for the reply. It's not so much the spacers I'm worried about. I'm running some on mine right now. It's the lugs that are on the spacers.
There's gotta be some people who don't buy only rims for Z's and use this to buy Honda rims.

Well, I don't see what hte difference would be between the lugs... They might be a different pitch, but they'll hold the wheels in. People race hondas all the time (and I don't mean the ricers), autocross, dragstrip, track, etc. The stock setups hold up relatively well, and the Z isn't heavier than the civic. ie. stock '00 civic Si weighs in at 2600lbs. My 73 240 with full gas tank, '73 bumpers, and 20lbs of tools weighed in at 2427lbs. It's now probably about 2400 even with full tank

I share your concern on these adaptors! I've been a tool maker for 35 years and I don't make anything out of aluminum! You can't expect to put steel studs in, and tighten steel lug nuts down on aluminum without some deformation. Look how deep the counterbores are. If they have a CNC lathe and mill, why can't they make it out of steel? My other concern would be the amount of offset farther outward past the wheel bearings. This causes greater stress on the outer bearing.
Just my opinion.

different grades of aluminum. It's lighter, it can be just as strong as needed (ie. t6061 which is aircraft grade), and it will hold up to abuse. Would you rather have 1lb aluminum, or 5 lbs of steel per hub?

Don't forget, you fly in aluminum planes.

im running thease same adaptors on my Z and im glad i did.. like AUX said porsche has ben using adaptors for years on thier 911 turbos with 10" wide wheels and rarely do i hear about thier wheel bearings going out.. the adaptors are well made and are well ballanced.. and you get more options on rims for your car too since all the new style rims dont come in "0" offsets..=\

icice9,
Thanks for your helpful input. Is that site the best place to purchase them? I've been getting a lot of static for the rims I have, thinking I should upgrade. What size do you have? Do you know what the largest is w/no problems or modifications? I hear 17's, but what width?
You Z look friggin dope, seriously!

icice9

those rims i have on are 17" x 7" wide.. you can go with 8" in the rear.. but 17" x 7.5" is probably your safest bet.. theres a few other places to get the adaptors but modern motorsports i think is your best place to get it.. before i got mine i did a lot of research to find the best place to get them and modern motorsports name kept coming up and i talked to a lot of other Z owners who had the same adaptors and all of them had really good things to say about his product..

I did a little more checking around and found that 2024 T4, and 7075 T6 is what is used in airplanes because it is almost twice as strong as 6061 T6. Sorce of info, Machinery Handbook. As for Porsche Racing they use forged aluminum adaptors. Mazda uses aluminum hubs on the front of the RX7, (forged). 6061 T6 is chosen because of it's resistance to corrosion without anodizing and it cost about half as much. If you think that "I've never heard of any problems with them" is a good reason then go ahead a try it. Steel weighs approximately 3.5 times more than aluminum. If I ever need some I will make my own out of 7075 aluminum.

Ramz,
Why do you make me some too?
But thanks for the info though, I might give them a try. Been spying out some white 7 spokes for my ride.

I would love to run off a few sets for all you guys, but I have other things I have to do first. Those beautiful 17's will have to wait. I hit a snag on the turbo zx brake upgrade. Seems they don't safely bolt up like they said!
