How’s the initial ride quality? When is test day?

Hey cool pics! Such an executive looking car.

You’re working that wheel lol. 2:01 seems pretty good to me

Surprisingly rides better than my worn ohlins even at much higher spring rates. Shakedown will be second week of October, either at Thunderhill West or Laguna.

Working it a little too much I'd say. Still have lots of room to improve as a driver.

Yeah lol I’d think the car could maintain better corner speed than it’s looking in the video. So maybe being smoother can allow you to hold more G and therefore more speed through the corners.

Make sure to get great exits, take advantage of the power of your car.

And good entry (without sacrificing exit) using trail breaking

Thanks for the tips!

You didn’t get the complete setup with the JRZ camber plates? I can get -3.9 with the JRZ plates on stock arms, also no issues with a 6” spring with an additional helper spring as well.

I already had vorshlag camber plates, so all I needed were new spring perches. 6" springs with the helper springs raised my front by 15mm even at their lowest. We could've made it work by also raising the rear by 15mm to maintain rake, but we wouldn't have been able to get as much camber all around. Keep in mind A90/A91 front suspension isn't the same as the G2X, so your experience is unfortunately not a helpful data point for us.

updated latest track day

[chrispy28_xd]

Updated latest track day. Did an objectively fast lap on the hardest norcal track. Goes to show that sinking enough money into a bad chassis can still get you decent results.

Still watching this latest upload. Great driving. Pretty fast for a “phat family car”, lol. At least we have 4 doors compared to our athletic, skinny brother (A90).

Great driving! Hard to imagine this is all on 255s all around, but back in the day one could only dream of having a 255 sized tire too. The car appears to be well balanced, front-to-rear, as far as I could tell in the video...not too much understeer and loose when you want it. Nice work.

[chrispy28_xd]

Thanks, and yeah the car's balance is really nice for me right now. Most of the understeer is due to overloading the front tires under braking though, so more rubber would help.

[CSBM5]

On a somewhat related note...any drawbacks to running the 9.5 ET25 with 255/35-19 all around on the street? Tramlining? Rears stick out too much?

[chrispy28_xd]

I almost never run my track tires on the street, so I can't say definitively, but the car is more affected by the aggressive suspension setup more than the wheel/tires. The only thing I can tell you is that I rub on the driver side when reversing and turning to the right.

[chrispy28_xd]

Updated latest track day. AIM is finally installed, so now I have more data to expose my questionable driving skills.

Thanks for sharing! LS look like an absolute blast to drive. A lot of elevation change and banked turns to lay into.
Major improvement in smoothness/consistency from your first to last session. Speculating here but you may suffer from the same beginner tendency as myself in overdriving the car your first session or two. It's a hard tendency to shake.
What additional data does AIM give you? All your data looks the same as previous videos from what I can tell but maybe i'm missing something.

LS is actually my least favorite track in the area. More than half the turns are standard corners, and the track is very hard on the car.

As for my smoothness/consistency, I've gotten worse as I've gotten faster, and it's something I, my coaches, and my friends are trying to fix. I may have to invest in a good simrig to instill better habits.

The key data point the canbus is giving is front and rear brake pressure, and I'm only using the front since it's doing most of the work. It also gives ABS which is useful to see how badly I'm overloading the fronts under braking (shows up as a blinking yellow light in the brake bar). I added which gear I'm in (inside the tach), but that was already kinda visible from the gopro pov. The AIM uses a 25ghz GPS so speeds and G meter are way smoother and more accurate. Lastly, I won't have to deal with OBD disconnecting every now and then.

There's also other data that it provides like individual wheel rates, but I'm not savvy enough to make a widget for something useful.

I've experienced the same. My best lap times do not feel the smoothest- they feel slightly wild - but end up being fast. My smoothest laps feel the best and are a little slower-but much more consistent lap to lap. My mentor insists-smoothness and consistency are the guiding light. I'm not in time trials- i'm trying to develop sound skills as a progressing driver. Anyhow, it sounds like you're getting the guidance you need. Just wanted to share the feedback i've received.

It's hard to imagine ABS not kicking in while under full brake pressure with a vehicle this size/weight. I would think it just comes with the territory of full brake application. Obviously avoiding abrupt and sudden brake application and unsettling the car is something to avoid>but what are you attempting to "fix" or adjust with reading the ABS data?
Again . . thanks for sharing your experience.

On shorter brake zones, it's better if I can avoid going into ABS since I'll have better control (laguna T3, T5 and T6 for example). I may have to back up the corner, sacrificing some vmax from the previous corner but make up for it with better entry and exit in the next. I've also become a fan of braking softer with a longer release than pushing brake zones deeper. It's easier on the car and is a safer and more reliable way of finding time.
