I have a set of ISF Rims being delivered (Friday)
Would these Rims Clear the 1995-2000 LS400 Front Brakes without Wheel Spacers???
With my current Set-Up there is slight rubbing when I hit a bump

What are the offset of the ISF wheels?

I had LS400 brakes and rotors on a Soarer UZZ32 (active suspension version) aka SC400 with 19" wheels.

The rims were 8.5" wide with +35 offset and the brakes only clear the rims by about 2-3mm.

See pictures from the link below.

I believe the rubbing is due to the tire wall. With 25mm spacer, lowered, & 245/40 on a 8.0" wide rim, the tire wall was vertical that rubbing the inner lining of the fender.

IS-F Wheels

19x8 : Offset : 45mm Fronts

19x9 : Offset : 55mm Rears

It looks like I would need a minimum of 10mm to clear the LS400 Calipers

Looks to be my choice in Wheel Spacers are my problem right now. Should I be safe and get a set of 15mm to clear the LS400 Calipers with IS-F Wheels or get a set of 20mm and chance Rubbing???

get both, test them out and send the one you don't want back and get credit.

A 15mm spacer should help, but the wheel will sit 10mm deeper than what you have now. It also depend on your tire choice. with that IS-F rim, what size of tires are you planning to put on?

If you use OEM IS-F size, 225/40R19 Front & 255/35/R19 Rear, you might be able to keep the 25mm spacer in front as the tires are a little stretched (no more vertical tire side wall) . If it still rub, change to 20mm spacer, we have SC owners with 20mm spacer, lowered, & no rubbing.

I have 19x8.5 +32mm with 225/40R19 on the front. its like 19x8 +45mm with 19mm spacer.
Rear is 19x10 +35mm with 265/35R19. Its like 19x9 +55mm with 32mm spacer.
My SC was lowered about 30mm with coil-overs. There's no rubbing except hitting a bump while cornering (Front). Hope my info help.

So the ISF wheels has the same offset as the stock 18" wheels. I would do a test fit, and see if they fit without spacers.

What is the size and offset of the LS400 rims?

The fitment of your new ISF wheels is as conservative as that of your oem sc430 wheels except for 1" bigger diameter, so you will likely need the wheels spacers for fitment purpose that can also easiely clear LS400 calipers anyway.

Offset has nothing to do with bbk caliper clearance. You need the high disc type to clear bbk regardless how high/low the offset is.
Wheel spacers have lower offset + higher disc effects at the same time wheel fitment wise.
