I'm glad too. I am trying to go to Hff Finale in Dec. You should come out!
What are the dates? I assume BW? I typically miss it due to being away for Christmas, I can try as a track season finale.

I went with the softer spring because I could always get the rear stiffer from my rear sway. The rear sway has always been on full soft. Also, from what I read, I should tune with springs first before anything else. Not sure how accurate that it, but I am doing it. :P

I also added the thrust bearings to help the spring turn during high stress. Not sure if it will be noticeable but they were cheap...
Great write up! You have the wheels spinning, time for me to read more into dialing in my setup. Best wishes with testing out the setup changes. :beer:

Yes, the Finale is December 16 at BW.


Also after texting Ryan, I thought I would post some links I reference when taking tire temps and responses to the data.

What wheels are you running? The stance, wheel size, tire size and drop look perfect imo

They are TE-37SL's in 15x8''. Patrick can confirm the offset, my guess is +32 or +35.

Correct and my offset is +32. Also, I am running a 225/45/15 Nitto NT01. The last time I set the ride height slightly lower than prior.

November Speedventures @ Chuckwalla:

First track day on new suspension updates.

So I was lazy and didn't get as much data as I wanted. If I remember correctly, front tire temps were not at even as prior, but could be just a psi thing.

Well, the car was a lot more neutral this time around with the spring change. I may need to bump the rear sway up for more rotation and try to counteract throttle exit understeer. The 1.5 LSD is showing its face now.

Only other thing, about the chuckwalla weekend, was the brakes. The rears seems to want to lock up easier than I remember.

Anyways, I got 1st in Mod class. :trophy:

Chuckwalla CCW pb lap 2:05.95, probably should be ~3 secs faster. so time is everywhere, this was my first time doing CCW:

Chuckwalla CW pb lap 2:05.88, same as CCW ~3 secs can be shaved. 4 years ago I I did a 2:08.xxx on CW:

Updates:
Fresh NT01s


So I decided to purchase new NT01s. I've always bought used nt01s from buddies or craiglist specials. the Nt01s I used for chuck,and my last time at buttonwillow, were dated 2014. Now idk how they were stored or if they lost grip but I thought new ones would be better.


December Speedventures @ Buttonwillow Hff Finale:
Honestly this track weekend was a wash in terms of tuning. I was having too much!! to focus to much on the car.


I didn't pb, track conditions were kinda dusty the whole weekend. I clicked off a 1:59.9. Everyone seemed to be off pace for the weekend. After first session on the second day, I came in the pits and noticed I had no rear pad at all. I need to upgrade, I've been using oem. I'm gonna get xp8s for the rears. I sourced some pads that worked and went out second session. I didn't get a clean lap and on my flier my distributor rotor decided to come loose.

resulting in:

Surprisingly, the auto parts store didn't have one. I decided to pack up and head home.
