I'm finally jumping on the LS400 front brake mod. Will post pics when installed. I went with a re-manufactured set of calipers, drilled/slotted rotors, just ceramic pads for street use, Megan racing 30mm RCA's, and Stoptech SS brake lines for the front and rear. Also will be moving to DOT-4 fluid and will paint the calipers with some nice Lexus logo stickers I found on ebay that are sized right for the LS400 calipers. Gonna look sweet.

I thought I would share some photos of my ls400 rotors and pads. I went with reman calipers and weaver rotors. I painted the rotors black just for fun. I know a lot of people around here have questions on what wheels to use/ or spacers. I decided a while back to move to 18's because my stock 17 was cracked. I did my research and found that the knock off 18x8 LFA wheels where cheap and would work if I with a LS brake swap. As far as the fitting the calipers I am running 30mm RCA's on the front and rear on stock suspension. I did have to cut the dust shield back to fit the calipers. So here are the pics:
Is this a straight fit?

No need to upgrade the rear at stock power levels. The LS brakes do help a little, but pad choice will give you better feedback with this upgrade.
I used FIGS 15mm (could be 18mm) for my RCA's, gave it just the right amount of drop on stock suspension.
Regarding the newer IS style wheel, I'm not sure about the clearance. IF you can measure the wheel from the hub mount to the back of the spokes, that may help.
I have found that most concave wheel designs will clear the 4 pot calipers.
