Can imagine the offset of the sporting alloys is around 40
So with the spacers will sit at about et25 and on a 7J wheel that would sit ok
Not sure about your sums here.
Offset is how far the mounting face is from the centreline of the wheel. So a 40 mm offset puts the mounting face 40mm outwards from the wheel centreline. A smaller offset moves the wheel inwards, larger offset, outwards.
Any spacer on the mounting face of the hub will move the wheel outwards, increasing the offset. So a 40mm spacer will move the wheel out by 40mm.
You need to know the width of both old and nee wheels and their offsets before calculating what if any spacer is needed.
Due to me having 8J wheels it pokes a little but I camber them.
Here's what you want to know. Fit the spacers. Don't worry. I can promise you everything will be fine... Simple as that honestly i sit with a wider setup and have no problems other than a little rubbing here and there but I'm lower than you
The lower the offset the more the wheel is pushed out. Offset is measured in mm. So are spacers. 40mm - 15mm = 25mm.
"a little rubbing" Good grief! If the tyre is rubbing it will eventually wear through and go bang!
This is illegal because it is dangerous.
The vehicle manufacturer spends millions on research and development. You've spent 50p. Which do you think will work best?
@portland_bill I do appreciate your explanations but I think you may have got the wrong idea here. I'm not looking for spacers to allow the wheel to fit correctly, rather im looking to widen the stance of my car. My current wheels fit fine
The spacers state centre bore of 56.1? If that helps at all? Still not sure on the offset
@but what I do worry about is if yours sat flush before bolting on the wheels? I find it difficult to get it flat against the hub all the way round
I spent more than 50p getting the stance I have. Custom made spacers by RH that cost £200 then camber shims, another £50 and if you count the wheel and tyre setup that's another 800. so go complain to someone who cares what you think, my car is fine and it looks how I want it to look.
And your totally wrong about the offset and spacers. The offset it reduced by adding spacers it's simple logic :bang:
