Offset question

[Granadaman72]

Hi, I'm looking at a set of wheels ive seen for my 89 Sierra estate at the moment, they are 8j and et -32, ive done a bit of research into offset but I'm not that clued up, by my reckoning they will stick out quite a fair bit past the arches if fitted, is that correct? Wouldnt mind a little bit of poke and stretch but think these will be an aftermarket arches job! Think Sierra's are 35-40 as standard?

I don't know the specifics of Sierra fitment, but generally RWD cars have a neutral/positve offset and FWD have a negative offset. This usually means that FWD wheels on a RWD car sit a lot further in the arch (if they actually clear the suspension) and RWD wheels on a FWD stick out further than they should

Sierra is 35 to 45 which is actually a FWD ET

-32 is a lot compaired to standard TBH steering will be heavy and as you say arch clearance may be an issue?
Sierras have a fair bit of clearance, my P100 has 2 inch wide PCD adapters and the transit wheels clear but they do have a large inset ET of 50-60.
