I saw this on another thread about wide-body kits..

hmmmm?!?!?!?

These specific ones? i dont recall ever hearing about thses specific ones.

 

I dont recall either, and I've searched........damn I could of used this along time ago.....too late now.

Thank's anyway Bern

 

Do they make those that fit a 4 x 110 to convert to a 4 x 114.3?

Also, how does that plate attach to the rotor, and not touch the wheel you will bolt to it?

 

anyone used these before? i am also interested in knowing how they bolt up without the plate bolts touching the wheel. anyone?

 

Those look dangerous. Only three bolt holes. That's assuming they work at all as I can't see how the bolts will fit between the spacer and rim.

 

Look again...

3 old holes,1 still being used as for the new stud layout..


Here you stillhave to worry about offset

How much is it for this set up?

 

From there web page:

"79-85 1st Gen RX7 "IRONSIDES" Adapter Plate
Converts the stock rx7 4 on 110 mm Bolt Pattern to a 5 on 4-1/2" Bolt Pattern like the 2nd and 3rd Generation Wheels! Retail is $599.00
Our WHOLESALE is $399/set of 4"

I remember discussing the billet aluminum ones, but i dont think there were ever steel plates brought up. What i dont get about these is, how does it stay centered? It seems like if you used one of the old bolts, it would spin lopsided. Looks dangerous.

 

You could get the hubs restudded to a five bolt pattern by a machining shop for less than that price...then you wouldn't have the offset problem and it'd be a lot safer than those things appear to be.

 

i agree with kypreo...

I believe it is only three bolts holding this thing on. the car is a 110 mm bolt pattern and the adapters is a 114.3 mm pattern. I have seen 4x114.3 mm adapters use a lug as support while the other lugs were trimmed to sit inside the spacer with lugnuts tightening them down. then the spacer actually had only four lugs popping out and the original was utilized in the 5x114.3mm pattern. If they used a stud from the 110mm pattern I think the other four lugs for the pattern would be offset from the center of the hub making an uncomfortable ride. Not to mention that only three bolts holding my wheels on is slightly uncomfortable in the piece of mind department. I have been taught on how to torque down 4 and up lug wheels whats the torque pattern on three?

thats what i was trying to say. but i just couldnt word it well. thank you.

 

no problem

 

I've seen others, can't remember which threads do a search.... Others that use 4 bolts to attach to the hub and convert to a 5-stud... I wouldn't trust anything that is only held on by 3 bolts (and with the *size* of my bolts, the wheel wouldn't fit over all of it)..

It's a good idea, but look for one done right, not one that has crappy MSPaint-modified pictures of it.

Well, I sent them an email with our concerns. Here is there reply.

The Ironside's Adapter Plates uses all 4 Bolts to attach it to the Rotor of the RX7.
We have not shown the key element to the Kit (which is included) so as to not allow others machinists to copy the design freely.
Yes it is a Bolt-On item, and they can be installed in 3-5 Minutes per wheel.
THey are extremely solid and we can tell you that your original Rotor will break LONG BEFOR these pieces will.
They are machined in 4140 Steel and we use nothing but Grade 8 Bolts that are also included in the kit.

Next time I'm near wellend, maybe in two weeks, I'm going to stop by there shop and have a look at these things and see if I can get a better price.

Cheers

 

is that price in canada dollars? in us cash that is a lot more than it can be done for. http://www.balancemachine.com/

these are just a few I came across while looking for other posiblies to finding my 1 missing epsilon 3 piece wheel in a 15 x 8

 

the cheapest that I could find for the 4x110 bolt pattern was over $70.00 each. With a fab time of about 2 weeks and I think I contacted all on the above list.

 

Correct, but that will only work on an SE suspension.
the 12A cars don't have enough MEAT on the rotors to go through re-tapping safely.

 

I agree with directfreak

 

You're not retapping the threads, you're drilling four new holes and putting in fresh threads, all holes would be exactly like stock, just in a slightly different location. And their location would not weaken the structure of the rotor any significant amount for the application.

Solution for wheel spacer pictured in top post for all four points to bolt down: use a fifth thread-in stud in the rotor that extends through spacer to wheel, or use a bolt that does the same from the wheel side. FYI - you could get those plates made for less than $100 with hardware by any half-competent machine shop.

Not a horrible product, but someone should tell them to consult an engineer...it's not like copying a body kit afterall.
