At 125mph and the rear wing dragging the car back (my gti could hit 131 mph at the same point), the front end gets pretty light and twitchy. The GTI was the opposite, the rear would get light and twitchy

and that's a lot more sketchy since turn 1 is typically 75 mph +.

Right on! I am there with my Z as well. Aero balancing can be tricky. There is thread I started that speaks to some things to consider. I was mostly focused on spring rates for coil overs with a big wang and a 5" front front splitter. I haven't driven the Z in almost two years so it is going to be fun! Hopefully she will be track ready in the next couple of months.

Just for reference I used this company that makes their splitters on order...(takes about 2-3 weeks) I have the stillen front fascia and my splitter fits perfect. They have splitters for several different aftermarket bumpers. Take a peek.

It doesn't appear they have a chassis mount option, and it looks like the "fang style" mounting option they have has an inappropriate angle to the ground. Maybe this design is more intended for a low speed/autocross situation with a higher rake setup?

How do you like the stillen fascia? Seems like it might be comparable to v1 nismo in terms of aero/ducting capability?

I like the Stillen... some people had issues with dimples showing in the front but I don't have those issues. I have some pix on in my albums. It's one of the best front bumpers for getting air into the engine compartment.

So what are the two side vents for the stillen bumper feeding? I thought they were for brake ducts, but looking at the fang kit, it looks like the brake inlets fit into the main grill assembly?

It does look pretty mean though, and especially with the wrap color! I might try my hand at doing a wrap over the off season. Never done anything even close, but I'm not bad at painting, so hopefully some nuance and patience translates.

Correct... the fang kit in the main grill has the 2" hose kit that runs to the back of the rotor. The 2 big openings on the side just feed more air behind the bumper that flows thru the engine compartment.

and you're right about the angle... Once I put the splitter on it points upwards appx 5-6 degrees so I need to level that off some. Also have the fangs with the front brake cooling kit too.

This car is new to me, so a couple weekends ago was my first time in it, and my first time in an aero car on slicks on a road course. It was also my first time back in a Z and back in a 3 pedal car since early 2016. I have some relearning to do, and I have to move the fixed seat back (my elbow kept hitting the kidney seat ridge when trying to shift) before I get faster. It's setup as a TT3 car and I compared my times to the TT3 and TT2 drivers that were out that weekend. I was about 1.5 seconds ahead of the TT3 cars out and about 0.55 seconds behind the one TT2 car that was out. There are easily 2 seconds I'm leaving out on the track though, I know it!

It's so nice to be back in a Z! It really only took one session before the car started feeling very natural!
