I'm not sure what's worse, the fact that it's held on by three bolts, or the fact that it's an adapter plate in the first place...

That being said. I don't think I'm all that interested in it, and those of you that are, please stay away from me on the highway... Or at least pull over when you feel the vibrating of a loose wheel.

EDIT: Never mind... I saw the 4th bolt... I still prefer the full on GSL-SE swap.

 

Last I checked though, the GSL-SEs are 4-bolt, no? This is a nice idea for those of us lunatics doing an FC front subframe swap. IE, me.

... though I think I may just get the holes in the half-shafts redrilled. Simpler.

 

What offset would you use after using those adapters?

 

The adapter plate. I can just imagine it now, wobbling wheels, wheels popping off, etc from the accelerated wear on the bearings and ball joints.

If I didn't already have so many spare sets of rims, I'd be doing the swap to GSL-SE suspension.

 

Can anyone PLEASE point to evidence that proves that adapters like these are dangerous and have caused serious injury to car or person.

 

ok, I dunno what happened with the cut & paste there... Apparantly I'm a retard.

I don't have anything good or bad to say about these personally. I amready have an -SE with cool wheels I just saw them posted and felt obligated to pass on the info.

Anyone trying them?

 

First off though, I'd like to point out that "new design" of such a "new idea" has been posted here before. Hell, you can get almost the exact same ones off e-bay for crying out loud!

And just look at how "official" their site is! Wow.. I should get a sticker saying "Yahoo! Racing", that will add at least 5hp to my car, because everyone knows decals add almost as much hp as ground effect lights! :P

I wouldn't personally trust 'em, but that's just me.

As far as I can see, if they were properly designed, the only problems would be slightly accelerated suspension wear, from the additional offset needed to put the wheel back in the wheelarch. It's steel, so there's no need to worry about dissimilar metals, and it looks like the wheel studs are pressed in so I'd doubt they'd spin free allowing the outer lug nut to work loose. And as far as the allen bolts holding the adapter to the hub, it's probably no more likely to come loose than a stock lugbolt. That's something I check frequently on my car anyways...

for $300 i would rather pick up some se suspension and do the conversion. if it was cheaper, i would be all about it. i plan to use adapters eventually when i need a bigger rim on my car, or ill go with the kosei k1's. 13kredline used them on his car, race cars use them, i read a post about some guy using them, and he said he was more worried about the lug bolt ripping through his rim then them coming out. i dont see whats so "unsafe" about them if they are made out of the right metal. also, alot of the people who dont use them, never have used them, and probably dont know anyone who has used them. if you dont trust them on your car, fine, but you dont know they will fall off or anything of that nature.

//rant off

 

For $300 you can usually find a good GSL-SE suspension and related items. What's better is that you'll also have upgraded brakes along with the SE swap.

 

unless you personally have had those wheel adaptors.... dont knock them..... its like being a hipochrit (sp? )


but yeah, I dont see any problems using wheel adaptors....

would be easier for me to use two of those, because i want a second gen front subframe, and then disk rear...... those on a GSL rear would be kick ***..........

all wheels matching...


good product posting eric


anyways......

 

it looks like it uses a long stud for one of the lugs to pass through all the way to the rotor, so I would'nt say it's only held on by 3 lugs....

 

The main problem with those adapters is that they aren't hub-centric, they are located solely by the bolts. Then, the wheel is mounted to the adapter solely by the studs. Between the two, there is a greater chance of the whole assembly being out of balance, albeit slightly.
That's why road racers generally loathe 'em.

 

I'll stick with my limited choices in the 4x110 pattern thanks. I wouldn't trust those things over 5mph

 

No evidence, yeah that's exactly what I thought. Look guys, these things are made from a machined steel using grade 10 hardware. As long as they're machined on-center I really don't see a problem with these things. Heck, they're probably stronger than the wheels you bolt to them.

 

Gents,

I agree if the kit were held on by 3 bolts many people would die. What you can not see, is the back of the 5th stud that is in the place where the fourth bolt should be is threaded and bolts into the rotor as the 4th bolt. Otherwise, wobble and safety would be issues. The backspace on a fb wheel is 4.5 the back space on a fc wheel is 5.5 and the spacer compensates for that difference, leaving the wheel and tire in the factory location. We have customers running 290mm drag tires that can not break the adapter and it was very well tested prior to release. As for vehilces it will not work with, GSL-se not a 4x110 car, as per the ad line 4x110 kit, the se shares its bolt pattern with enough cars. The kit is also designed for rear disk cars only. Aside from that, you will never break it and it will not wobble. Hope it helped. email me if you need any more info. farmz1@hotmail.com

ah ha! the owner

so the adater/spacer allows for the useage of wheels with the FC offset?

that's pretty slick! good work man!

now if so many 1st gen people weren't such cheap bastards..

 

 

You want a ******* newspaper article or something? Read Wankelguys post right above my previous one and think about it, all the force is now on only the lug bolts. Would you really trust that?

 

Yes, got one?

Yeah so what, a LOT of cars wheels mount that way.

 

That's very true Bob, but that doesn't mean that it's the ideal method, especially for high-speed use.
That's why I mentioned that my road-racing friends won't use 'em.
I'm by no means a wheel expert, I just wanted to bring up a point that I thought sure many people were not aware of, so that they could make an informed decision. Whether or not this is an issue for concern is up to them.
I think that's reasonable, myself.

 

Obviously I don't have any proof, and yes not all cars mount their wheels like ours, but if you drive hard why would you wanna risk the car and your safety just to have a fancy set of wheels? Plus, not only is it not being held by the hub anymore, you've also twice the fasteners that can fail on you. And if one does your fucked. But what do I know, you want em then go for it, but I'll never use them.

 

I just think the dangerous sentiment around these parts is a little far fetched that's all. Clearly they are not ideal and perhaps some racers prefer not to use 'em.... but dangerous? I doubt it. I'd change my mind in a heart-beat if someone showed at least a shred of proof that these things have caused damage. It's kind of along the lines of the synthetic oil kills rotaries mantra or ATF fixes all BS around here.

 

Jeez, no one ever said these things were dangerous or that using them is patently unsafe, at least on this particular thread. I actually think they've gotten a pretty fair shake. Maybe you're perceiving more of a negative bias than I am, I don't know. But we shouldn't be getting on each other's case over it, anyway.

Now if you'll excuse me, I have to drain the synthetic oil out of my car and ATF the hell out of it.
