Changing a wheel stud pattern - possible?

what the hell has that got to do with it,its just a bit of machining?
My ally hubs are a modern bit of kit, billet cnc machined for competition,far better quality than some cast iron hub from a factory produced car of the eighties,not that it makes a blind bit of difference.
(even though they are designed to be fitted to cars that regularly will take off and land full weight on said hubs)
All you are doing is changing the position of the bolts on the hub,not altering any geometry at all.the wheel will still sit in the same place.
redrilling hubs will make no difference whether its a nsx,a daf 33 or a veyron.
Exactly. Your hubs are most likely over engineered for the task of racing. As far as I'm aware suspension bits are designed with a 3x safety factor. All your doing in your case is eating into that safety factor.

The hubs we're talking about are made of Iron, which is more brittle than steel, and less resistant to shock loadings, so if you're taking material out you're increasing the risk of developing cracks from riding over potholes and such, where you NEED that safety factor. These shock loads are far more likely to break suspension components than 'landing on its wheels' when you're racing.
Its all well and good with practical experience and what i'm talking about might be overkill, but personally I'd be very careful when it comes to taking chunks out of something that holds on the wheels of the car that will have been VERY precisely designed and engineered by a lot of clever people, particularly when it comes to a sports car where they would have been looking at minimising unsprung mass.

Wouldn't that reduce the strength of the hub?
No,not at all.I have ally hubs on my capri,they are basically a tubular holder for the bearing with four `petals` sticking out at one end,one for each stud.
these are made for race/rally mk1-2 escorts,if they can take that sort of stick the cast iron ones on your car will be more than up to the job.
not forgetting when the disc is fitted to the front of the hub it will also need drilling.
BTW some merc hubs are drilled in this fashion from stock.
Please read what I said originally
Would be very careful with that, 90's CAD engineered Honda will be more tightly engineered than 60's-70's Ford or ancient Hot Rods designed on hand calcs and intuition

The more holes in the hub the weeker it will be. (FACT)
But I would imagine that machining the hubs depending on where the new holes end up in relation to the original holes that they will be fine.
