Suggestions for braking and aero

Weight is around 3075 empty, and it's probably not terribly far from 400whp on a DynoJet. I would expect closer to 124-125mph with 450whp, but weight plays a big part.
You'd do a lot lower than 11.7 AND higher than 119mph with a launch. 11.7 without a launch is a pretty fast car.

You'll find that dropping your 60' compounds your ET gains - it's not just a 1:1 ratio. If you drop from 1.86 to 1.66, you may drop as much as .4 seconds off your ET. I could envision 11.4@121 with no changes besides a good launch.
I did trap 121 once.

Ok, all, I'd like to re-cap and essentially close out the thread...at least relative to my initial post.
- I'm leaving aero stock. I'm focusing on braking and tires. I'm also not worrying about switching between drag and track. I'm focusing only on track.
- For braking, I went with the Essex AP kit using the Ferrodo DS 1-11s for now, replacing my old SS lines, and using AP PRF 608 fluid.. In the rear, I'll use my new Hawk HT-10s for now.

It's not about "bigger" brakes, but rather stronger and more efficient brakes. I think my kit is the same size, but they will bite harder and last longer during successive turns and laps. My previous setup was stock with SS lines, slotted rotors, street pads (HP+), and decent fluid. The way I run my Evo easily overwhelmed that setup.

i'm hoping to not need a brake upgrade any time soon, as i have lots of other things i'd like to get done.

Kaj, as a follow-up, the Essex/AP brake kit was amazing. I only got 2.5 test sessions before wadding up the Evo (not a joke), but my honest "feel" is that I wasn't actually able to push the brakes to their limit...partially due to how good they are but also due to my intrinsic timidness based on what I EXPECTED them to do (mental bleedover from the last time I ran on the track).
On each lap, I was hitting about 145 (on my stock speedo at least) at the end of the straight, and I never had any sort of brake fade or lack of bite. However, I don't think I ever properly bedded them, because I had nowhere to do it safely. I was also hitting 110-115 on the back side of the track with a hard left turn at the end, and the brakes stopped me well short of my turn-in point multiple times (while I was still learning the track and the car's performance).
