Machining Wheels To Increase Offset?

Hi,

I have some new 18x9.5 wheels on my Stagea and have an issue with the rears sticking out to much.

The centre of the wheels appears to have plenty of meat on the inside of them, so I am wondering if it would be possible to get the inside face machined down to increase the offset?

They are currently +12, I think around +25 would be perfect, so machining off 13mm.

These wheel also come in +30 and look exactly the same, so I can only assume that they make a cast and simply machine the face to the required offset?

As long as a reasonable amount is taken off, is this safe? What sort of place could actually do this?

Thanks for any help.

There is a nominated distance between the hub face and the wheel nut inserts or tapered edges. By removing material your making the distance less and increasing the chance of the rim cracking around the stud holes. Ive seen it in the past.

If you did do it, use a Milling maching with a parrallel flycutter, and be cautious just how much material you do take off and how tight the wheels get done up.

make sure when its done the rims get clocked to the cutter properly otherwise you'll end up with nice wheel wobble. Any competant machinist will realise the importance of it being square anyways,

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
