offset difference with coilovers?

I have been looking into new rims for a little bit and am having trouble finding a clean pair of rims that i like with our offset. I was talking with some suby guys last night and they were telling me that with the Tien SS coilovers i can use a 40 offset tire thats 8, or 8.5 inches wide. Because the cars on coilovers it shifts the weight of the hub so would running a 40 offset be ok? Ive heard of some companies running 9.5 and 10 inch wide tires on 32 offset. Rolling the fenders would be fine, but i am just curious about if i can fit 18x8.5 with a 40 offset with SS coilovers. thanks.

do you mean s tech springs, because that will not change your offset.

edited to make more sense. I mean coilovers not just springs alone.

I don't think most coilovers shift the offset anywhere near that far. Stock is 53mm...

The farther out you push your wheels the more wear there will be on your wheel bearings.

coilover has no bearing on offset, as you go wider in wheel width you typically lower offset a little- this is strictly a fitment issue, with a high offset rim (ie 50-ish) and a wide wheel/tire combo you can run into inboard (against the strut) rubbing- a lower offset allows better fitment of a wider combo- as mentioned above as you lower offset there is more stress on the wheel bearing/hub assembly- that's why folks recommend sticking w/ offsets in the mid 40-ish + range

a coilover setup can exacerbate inboard rubbing issues as the spring perch typically sits lower than w/ a oe style strut/spring combo- this often necessitates the use of a slightly lower offset wheel (or spacers)- you still have the additional stress related to a lower offset

9"+ wheel widths are usually reserved for motorsports application (maybe a show car heaven forbid)- wheel bearing/hub replacement is typically a routine maintenance that is done after every race
