Novice wheel tech question: offset & stud convertors?

OK, I know I should know this by now, but I'm really struggling with wheel tech. 
25mm 4x113.4mm to 5x114.3mm stud spacers on a MA61.
1. Would that bring the offset out to 33mm?
2. If not legal, would anyone be able to know they were there
at a glance?
3. How would you bolt the spacers in place?
Thanks folks,
Justin

quick answers...
1 - ??? no idea as you havent specified the offset for the 5 stud wheel.
2 - converting the number of studs is generaly a bad idea using a 'spacer' or adapter. Converting the whole hub and brake assembly is a hassle and can be costly, but is safer in the long run. Either that, or stick to 4 stud wheels. Best thing to do is contact your local transport authority and ask them about the legalities.
3 - there should be instructions with them if you bought them new, otherwise we would need you to post some pics if you could 
Hope that helps...
Craig.

Cheers,
They are on the JMS website (I haven't bought them). I would have guessed that stock 8mm plus 25mm spacers would have made for a 33mm wheel being ideal. No?

Someone I once spoke to was saying how 4-5 stud adapters are dodgy. I don't know whether they are legal. I have seen them in a magazine on a D1 Drift car in Japan, so when properly engineered they must be strong.
Don't know how legal they would be. I'm pretty sure hub extenders would be legal, and would give you a large choice of wheels. S13 Silvia's run 4x114.3, as do some Hondas. With a larger offset you would have a lot more options.
You would effectively have a +33mm offset with a 25mm spacer as well.

Cheers Franky,
Also note that I asked about the likelyhood of getting caught, not if these would be legal  Does that say something about my current mentality?
This does open up the options for big wheels.

Paint them black 
Seriously though, if you were going to get proper hub extenders made up, I can't see why these couldn't be engineered, especially if you are just "restoring the track".

Yeah, spacers would open up a world of S13 possibilities.
I still don't get how those JMS hub adaptors would bolt to the stock hubs

Try this website to see if it helps walk you through the changes to offset you are asking about.

Okay, here is a quick run-down of how they fit.
There will be 4 holes in the original one, which the original wheel studs stick through. You bolt the extender to these. The extender (well, a good one will) actually fit snug around the centre of the hub to hold it further in place.
The extender itself will have 4 new wheel studs of its own, and this is what you attach the wheels to. Fairly self-explanatory with the 5-stud ones, they just have 5 new wheel studs on the extender but everything else is the same.
Follow me?

Thanks JCMF,
It sounds self-explanatory - it's just from the picture I can't see how it would sit flush.
Amyways,it sounds interesting.

If anyone can make them can they make me a set that changes from 4*4in to 4*100mm. I want to use some small mags other than minilights on my mini.
