How much offset is needed?
Alright to start things off i am looking to start my winter build on my 96 LS400. I am considering purchasing these four steel rims for winter. http://www.ebay.com/itm/Cragar-Black...hVAWin&vxp=mtr
I've attempted to do some research, but I guess I don't really understand rim offset. I know that the brake calipers are pretty huge on the 96 ls400 so I would like plenty of breathing room between the rims and brakes. The offset for stock ls400 rims is 45mm, and the offset for these steel rims is 0mm. So I'm assuming that I will need 45mm hubcentric wheel spacers for the front, and probably some for the back so the wheels don't look all wonky. Just thought that I would ask some LS400 gurus instead of just buying something and not having it fit. I really want to go with the off roady look for winter, let me know if anything like this has been done before that I can take a look at. Thanks guys!
PS. I have Megan Racing coils that I plan on raising all the way up and possibly buying a used diff and just welding it shut for the hell of it.

a simple read:

you have it backwards. the lower the offset number, the more the wheels move away from the car. so you should NOT add any spacers whatsoever just to get back to stock specs. at 0 offset, the wheels will actually stick out moreso than stock, if they even clear the brake calipers in the first place, which is another issue.
caliper clearance depends on the wheel disc or pad. in other words the wheels need to have a provision for the large width of the LS400 caliper. most steel wheels i am aware of, even the 0 offset ones, do NOT have the correct disc or pad to clear. you need a medium to high pad.
for example
a safer alternative is to pick a wheel that is known to fit your car, such as other lexus stock alloys as your winter beaters. maybe even find another set of stock wheels!
