You're talking about the 4 mounting points of the subframe to the chassis? I'm about to make some aluminum spacers to help remedy that problem. I'll snap some pics.

Seems I'm a bit past due for an update.
Normally for these swaps I modify a stock GM pan to clear the subframe. This is fine and all but with this being a high HP engine I'd like to keep as much oil in the sump as possible. To do so I was forced to section the front cross-member. Nothing a 4.5 inch grinder and a tig welder cant fix.
Knowing the camber/toe sweep of the IS300 was a bit on the aggressive side I decided to make my own lower control arms with the idea of minimizing the steep camber/toe curve. While I didn't take any good pictures of it; I actually performed a few tests with the car sitting on our Hunter alignment machine. With the strut removed I could raise and lower the car simulating a bump or drag launch scenario. By doing so I calculated my lower control arm length reducing my camber/toe rate. Here's the modified top hat and tubular lower control arm.
They look cool and all but what I failed to notice is that with the strut mounting location above the center line of the the LCA upon weight transfer the strut would tend to rotate the lca. I learned something...awesome that's the idea of this project. Learning and evolving as I go
So on to the new design. Still unfinished in these pics I built some LCA's with a shock mounting point below the hub/subframe center line.
Its nice to work in a shop with all the right tools and the absolute best backdrop.
I decided to invert the double adjustable coil overs in favor of some extra sprung weight. (still with the old LCA's)
The money shot (wide angle lens) Lower LCA's installed and fuctional. More updates to come soon.

Looks great!
Noticed your deck surface has GM's new BS tiger stripe High/low spot surface. Do you plan to resurface the deck? I just ran across this with my little JY build as well. It seems only the newer gen4 motors have this issue. I block sanded mine so its more pronounced. Have any better shots of your deck?

Forcefed86 My block is at the machine shop or I would snap some more pics. The wavy deck surface is pretty typical of most GM motors I've seen. The machinist I use is ridiculously good. I consider him an artist as his work reflects a labor of love. He'll be o-ringing the deck for a nice tight seal.

Awesome project! Can't wait to see more. The fender removal/tire fitting was pretty crazy, I like how it still has a stock appearance, very impressive.
I am doing a swap on a little "different" platform, it's a 2002 Subaru WRX getting an LQ4 6.0/317 heads/T56/ BW 476r billet, air to air intercooler etc on E85. Should be interesting.
