TrueGS300's build
Thanks everyone. So the fitment is flush, but definitely rubs on the fenders in the rear. I already put some gouges in the tires. So fenders definitely need rolled. I will be doing that next. The fronts aren’t a problem at all so I can vouch for the size up front. Of course the lower you go, the more problems you might have.
The fronts are 18x9.5 ET+35 w/ 265/40-18
The rears are 18x11 ET+40 w/ 305/35-18
I found that ET+45 or even +50 would have been more appropriate for the rear because there is still an inch of space between the tire and the strut. So if you don’t mind a less flush look, they would fit with likely no modification at all. I will update once I roll the fenders. This will make for a better final product, just more work involved.

I've made some progress on my other annoyances as well. Got a much better cold start tune. Fires within a few cranks now. Still takes some throttling for a good 20-30 seconds to idle out, but at least it's starting up and is good enough to daily. I also worked out my registration and waiting on the tags so I am legal to drive it again. Needless to say, a car like this takes a lot of hoops to jump through with the strict California requirements. I found a $10 universal set of mud guards to custom fit behind the tires. Will be workin on that along with the fender rolling before taking it out again. The paint will get ruined if these sticky tires are kicking debris up.
I fixed my major rubbing issues. The fender rolling was pretty much a fail. I destroyed them and lost paint even with the heat gun. Too embarrassing to take photos of. But they fit now. I also installed some hard plastic mud guards to help with the massive protrusion. They are too small and hardly do the job, but again, better than nothing. Also too laughable to post pics of.
As I break the tires in and am getting use to the new feel I’ve noticed some positives and a negative. First, I love 18’s. The wider width and more sidewall has made for a major improvement in comfort and less road noise. The traction of the competition tires inspire confidence and I am no longer losing the rear end on hard pulls.
Now for the one issue that involves more money and another full day of work. I now notice the need for improved dampening and handling. I am currently running the Tein street basis z coilovers. They are my favorite set I’ve ever run on any car because they are the most comfortable, quite, steetable set I’ve used. But with the massively improved grip on acceleration and cornering it’s like the suspension is floating. The lift and dive of acceleration and braking is noticeable and there is noticeable body roll in turns. Unfortunately there is no dampening adjustability on the basis z’s. So I will have to upgrade to a better set. I need a little tighter dampening also to stop the last bit of rubbing I’m getting on harsher bumps. Considering the Tein Flex Z’s but open to considerations.

These mid to lower level Teins are not rebuildable. They were more focused on lower consumer cost so they made a crimp style cast body. I even had a guy selling a relatively new set near me, but went brand new to start fresh. They are cheap enough at $800 shipped. Good looking out though 
I found my clutch master cyl to be leaking again. This time actually from the secondary seal that allows it to leak into the car. I kept noticing my reservoir going a little low. So that's another part to replace. I won't be doing the 3/4 Willwood at this time. I have gotten use to the 5/8 and don't want to make the pedal any harder than it is. Most of my driving is dealing with traffic to and from work. Luckily the master in my setup is from a 90-93 Celica and I was able to get a brand new Exedy unit on rock for only $30.
My tuner just sent a 3rd tune file to help idle after cold start (now that the actual startup is pretty dialed in). Going to be trying that out this morning. Slowly getting things worked out! So many areas I'm working on which is no surprise. Years of building and so many changes at once, and now driving it, there was potential for many things to go wrong. I'm trying to remind myself that the few things I'm dealing with really aren't that bad. A little fine tuning, tighter suspension, grippy tires, breaking things in and monitoring for issues. So far, if the used clutch master that came with my trans is the only failing part, I'd say that's pretty lucky.

Yea but it’s worth it to keep the geometry, steering and angles in check. I had looked at these before and considering how much OEM is, I’ll probably go ahead and pull the trigger on em
That's where my mind is at. At this point it's all that's left to dial in. It is more important than ever to keep the car glued to the road. Could be the difference between a safe drive or totaled car, or worse life and death.
