4 to 5 stud wheel adaptor (updated)

[scjimbo]

5x114 is going to be too close I'd imagine. Ill put it on the cad tomorrow and see

[ross_jsy]

I wouldn't want a set, but £100 a set is extremely reasonable. Be surprised if you knock them out for that tbh, what does a decent stud and nut set retail at?

Think it's £100 a pair mate.

Well the best ones I have found so far are Grayson. They are uk made and recommended to me by a Motorsport company. They retail at 2.60 ish per stud and about the same for the nut. When I spoke to the sales department today about buying in bulk, they came down to about half that. It's all about numbers at the end of the day. There won't be a massive margin with them. They certainly won't make me a millionaire anyway. It's about making a bit of beer money after work for me really. I will try and sell them on eBay etc for about 250 for 4

[Rav335uk]

I'm in for a set, so £200 for a set of 18mm ones

[leeparkes]

Is it possible to get them any thinner than 18mm?

[Rav335uk]

No Lee, due to material strength.

[scjimbo]

Ok i'll make up some mock ups and take some pictures so you know what you will be getting.

Yep £200 for four 18mm ones rav

[Quaser]

I could be interested in a set of 4 - depends if I can get my wheels under the arches without any mods, else I will have to have them filled/redrilled.

Whats the price difference for a thinner set out of titanium/stainless steel out of interest?

[adam_2922]

I would be interested around the £150 mark. The problem with adapters is that people buying adapters are buying wheels and tires at the same time. Theres very few people who can affod to do that without watching the pennies!

The problem with people buying adaptors, is they won't spend the £1k to change to 5stud properly and it seems that £200 is too much as well

£50 a corner seems a very fair price to me, considering what's involved to get these done right.

About £150 per pair for the stainless and the Titanium ones would be considerably more.

^^^Man talks sense.

£200 is cheap, even compared to mass produced one like they have for VW's like the 5x100-5x112 ones.

[adam_2922]

£200 does seem fair (my phone didn't update the new posts yesterday) I would be interested once you have a mock up.

I've got the billets on order today. I'll post up some photos as soon as its done.

[Coops90]

Ive got some shitty old 4x100>5x120 alu ons lying around doing nothing. Poor quality, but might be of use to your design?

[redcar]

I would be interested as well.

Cheers for the kind offer mate. If I need them I'll let you know.

What will fit on these guys with no arch mods

[ezagood]

im hoping a set of forge style 24's. they have a 41 offset so with a 20mm adapter they fit nice with the right tyre

[Rav335uk]

What will fit on these guys with no arch mods

Depends on the original ET of your wheels Matt.

[mwggriffiths]

Use this site to calculate the offset: http://www.1010tires.com/Tools/Wheel-Offset-Calculator

By putting an 18mm spacer on you're effectively reducing the ET of the wheels by 18mm, so a set of ET20 wheels would look / fit like a set of ET2's (So in this case ET2 is what you'd put into the calculator) . Work out what your current wheels are and apply that logic and you should have no problems

Just to drag this up! I'm awaiting delivery of a set of 4-5 adapters at the moment. I happened upon a set of genuine 16" rs's for literally next to nothing. They are 5x114.3 and had 225/50 and 245/45's fitted. I already had smaller rubber in the garage from a previous set of 8 and 9x16's I ran, so with the £250 adapters the whole show owes me about £400. My wheels are obviously jap fitment, from the tyre sizes I'm guessing skyline or supra, et30 front and et41 rear, so I have loads of room to play with.

I (wrongly or rightly) went for the offset bolt tupe from g23 engineering who seem to have some kind of good reputation on e38 etc so I thought why not? Given the offsets of the wheels I went for a 20mm front and a 28mm rear, giving me final offsets of 10 up front and 13 out back, my arches are already worked and I've ran et15 9j's out back previously with no issues.

If I don't get on with them, I'm left with a set of adapters from the most common (scene) pcd to a pcd which has an endless supply of nice/cool wheels in all manner of widths and sizes, which won't be difficult to punt on to the Wolfsburg crowd.

Adapters can be the answer sometimes, and the more common their use gets, the more important I think it is to have good quality, well made examples on the market!

£200 a set is perfectly reasonable mate and can't see you having any problems shifting them at that price if people know they are getting safe quality parts.

That said, the buyer needs to have the nounce to be able to figure out what they need/want regarding measurements etc, and as we all know, this is a quality that can be lacking in a lot of folk who decide to 'modify' cars!

[scjimbo]

Thought I would update for you all.

I apologise for the delay in getting these sorted. The machinery at work that I need has been stacked. I have finally managed to knock out the first prototype.

Points to note: on the finished article the 8 millimeter screws in the front will be countersunk rather than counter bored for strength.

The two stud holes in the pocket will also be jinked further apart for added strength.

Obviously the steel plate which retains the 100mm pcd screw is not finished yet so not pictured.

The finish on the real thing will be much much better than pictured. The tips we were supplied were not up to cutting aircraft aluminium.

Let me know what you all think.

When it comes to production ill get everyone to add their names to the thread so I know how many I need to make.

[Rav335uk]

Is there a need to drill both the 4x100 and 5x120 holes next to each other if there's a plate that fixes to the hub??

Like in the link below, it's only drilled for the 5x120.

There should be no need for it, as the plate that attaches to the hub fixes from below.

[scjimbo]

Yes rav you are correct there, however the problem with the design he has, is that you have to get that kidney shaped part lined up exactly before you screw the carrier on top. With mine the screw is already mounted inside. The other problem with his design is he uses a counter sunk screw to hold that kidney shaped bit in place. We have found through our experience in toolmaking that these probably wont come undone once they have been say a while which is why I did it the way I did. That hole you can see will allow you to do the cap screw up without disassembly.

The other good thing I have tried to include is that the 125 Pcd stud will also hold the steel plate in from the other direction which adds strength.

[scjimbo]

Having said that. If you guys think a direct copy of his design is better I can do that.

[Rav335uk]

No, design something you know will be 100%.

I think i'll have a better pic in miy mind when I see the mounting point on these.

[scjimbo]

Yeah you are absolutely right. It's very difficult to explain in text. When you see it you will get exactly what I mean

[Tan91]

Nice one watching this thread, I made a thread a year ago and nearly was going to buy the ones of r3v but never got around to it, finally someone will be doing them here in UK that we would feel confident in purchasing, I'm down for 4 adapters of 5x120 @ 18mm thickness. Basically same one Rav wants.

Price is also good.

Awesome Dude! Great work.

[BEMER_LAND]

Very interested in a set of these, have wheels just bought and wanting a set of adapters for them, whats the thinnest you could make safely with the stronger material?

[Rav335uk]

18mm is the thinnest you can go safely.
