G'day - I want to fit Rota RB (Minilite copy) 15 x 7 wheels to my '69 GTV, but the local distributor hasn't got a clue about which offset. Can anyone help please.

Does not that means you have to change the PCD? Or are you ordering a custom set with original 4x108 PCD?

Hi Dra,

Rota make an RB with 108mm PCD, so I'm ok there. Just need to confirm the offset before I buy.

What offset choices do they offer? All the rotas that I have seen on line for GTVs are 30 mm offset.

Rota Offset

Hi Brad,

Correct. Their website only has one offset available in 15x7 - 4x108PCD, and that's +30mm.

I have found an Aussie made minilite copy - Superlites by Performance Wheels. They will custom make any PCD/offset, and prices seem to be comparable, so that's the way I will go. I will post a picture on the 'What wheels do you have' thread when I get them.

Cheers,
Wazza.
:D

Most 15x7 rims for Alfa GTVs and Spiders are in the 20mm - 30mm range for offset. For 205 60 15 tires I would not use less than about 25 mm offset. What tire size and offset are you planning to get?

Hi Brad,

For the offset I will let the wheel supplier figure that out, then if they make a mistake it's their problem not mine. I expect the offset will be between +25 - 30mm.
For tyres - Alfaholics recommend 195/55 for 15" rims to give the best handling characteristics for a 105. So probably between 195 - 205, depending on the choice of tyres available.

I have the Rota RBs on a GTV. The offset is 30mm and I added 4mm spacers to get them to 26mm. I have 205 55 15 Yoko S-drives on them. I get a little rubbing on the inside on a tight turn in the parking lot. Another mm or two might help, so I will say from experience the final offset should be between 20 and 25mm on my car. They will not make them in the correct offset, so just get the 30mm ones and add some spacers. Obviously if you chose 195 tires, you could get away with only a couple mm spacers.

You will not be able to beat the price of the Rota RBs. If you must have the wheels exactly as you specify, you will pay a hefty price. And you may get the offset wrong, as everyone has a different experience with the offset on their particular car. If you can find a compatible 15x7 rim and mount your tires, space them with spacers, then tell the supplier what you want, you would have the perfect rim.

Hi Iachella,

Thanks for the info. It matches exactly what the wheel guy I just spoke to said. He said the standard offset was +30-35mm, but he recommended +24 for 15 x 7.

I will go with whoever offers the best price. I don't think you could tell the difference between the Superlite's or RB's just by looking at them.

I will also take Mike's advice (Goldcloverleaf) and get them to measure the centre hole, as he says the standard 4x108 PCD is made to fit a Ford Escort.

Cheers,
Wazza.

Question guys, sorry for hijacking, with 25-30mm offset, will the wheels still inside the fender or straight with the fender lines?

15x7 wheel offsets

Have a look on the thread what wheels suit GTV and photos of GTVs only. Examples of 15x7 rims of various offsets will be shown, as well as different tire sizes. As you know Rotas are usually 30, GTA replica 15x7 are 29, panasport 15x7 usually 25, the 15x7 on my car 22 with 205 60 15. I get very slight rubbing on rear fender lip on full suspension compression. If I could custom order an offset I would try 24mm with the ability to machine off another mm or 2 off the mounting face in the future if needed. I would stay away from spacers unless absolutly necessary. As for tires I would get 195 60 or 205 55 any thing smaller in diameter looks wrong.

Rota makes the correct hub bore. It's 73mm. I actually purchased the first set of Rota RBs in a 4x108 that the factory made. I made the mistake of telling them they needed to be 67mm. The wheel supplier offered to have them milled out when I told them I goofed, but I knew I was going to use spacers, so I told them not to worry about it. The front hub tappers and works fine. The rear is not tappered but is only 4mm deep, so it worked out fine. But they do make the 73mm bore.

Andra - I will take a photo of the car looking down the side later today and post for you to see. I don't think I can put into words what you are trying to know.

Here is the 30mm offset with 4mm spacers. You should not worry about spacers. There is nothing adverse about them if kept to a reasonable size. You need 7 to 10 thread depth to insure a good hold.

I took a few more of the other side too. Let me know if this is enough for you to see the result.

Thank you very much for pictures, Stefano! I also need a new wheels and tires in my case, but most wheels available where I came from, came in 4x100 or 4x114,3 PCDs. The solution for me is an adapter or changing the PCD, though still not sure about these two...

On my Alfetta (4x98) I got 4x100 rims and had them redrilled to 4x98. It is not very expensive when you find a wheel shop that does machining. I paid 150USD to have it done to all 4 wheels.

If you plan on getting a wheel that has a high offset, like 40mm or more and have to use large spacers, it might be better to have the adapter made in the spacer.

Also, Rota is based in the Philippines. That is close to where you are. They will not need to be shipped from Europe or the US. They have very good prices, too.

Rota mostly copies classic *** wheels like hayashi racing, RS watanabe, enkei mesh as well NISMO wheels for skyline GTR. I heard the company makes replica wheels (styling wise) with better durability than most cheap replicas.

They are associated with Driftworks, which you can get it from them or other European dealers.
