I didn't see anyone with this fitment but some say it wouldn't work to well but everything is okay with minimal effort.

Static on Megan springs, no roll or pull, waiting for BC coilovers to adjust the front, slight rub on rears on harsh dips. Rears sit flush but will change when I get new tires and the fronts poke out about 1/4" with 1/2" of back spacing. I hope most would use these specs to gauge how much you can go on springs for IS250 rwd.

Wheel Offset

Refers to how your car’s or truck’s wheels and tires are mounted and sit in the wheel wells.

– Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.
– Positive wheel offset is when the hub mounting surface is in front (more toward the street side) of the centerline of the wheel. Most wheels on front-wheel drive cars and newer rear-drive vehicles have positive offset.
– Negative offset is when the hub mounting surface is behind the wheel centerline. “Deep dish” wheels are typically a negative offset.
