It's too bad the auto tranny doesn't perform well under track conditions, yes the understeer is pretty horrid during high speed corning. When it starts to happen I always feel like the grip is going to break away.
1:36 is great time I'm sure you'll get faster with your Z the more you start dialing in the car. Can't wait to see what you do at Buttonwillow

Thank you Walter! I will bring the Z most likely.

Damn, I wanted to do the White Amuse + CE28n + 40th Anniversary Callipers

Just wonder if there is any reason why only the wing is wrapped in CF vinyl? Also, are the black accents in a matt black?

The bodyshop recommended us to wrap instead of painting the wing, so I decided to go with CF wrap instead of black. It's easy removable anyways.
The black accents were painted in Satin Black, because I track the car a few times in a year, gloss black won't hold up the duty.

Track/Course: Streets of Willow, CW (safety block at down hill chicane, organizer has tested about 1 sec. slower than normal course)
Best Lap Time: 1:28.81
Brakes: Stock
Tires (Size & Model): RE050A 255/35/19 and 275/35/17
Suspension: Stock with Eibach springs
Other Mods: Amuse bodykit, Stillen sway bars

Alignment spec: (Thanks to forum member MIKE)
-3 camber -.01 toe front and
-2.5 /.04 rear
This alignment works well on stiff side wall street tires. However, if you are running R compound or tires like RS3, go more aggressive like -3.5 front and -3 in the back.

Review:
- Stillen sway bars: I set front at stiff, rear at middle. The rear sway is too stiff, it causes less grip during corner exiting. Front is not stiff enough but I'm out of reach. I will reset the rear sway back to the softest setting
- SPC front camber arms: when I had them installed at the shop and aligned, one side of them came loose on the fwy during normal driving. After inspection, we found out that the lock bolt was not holding it up and the alignment shop probably did not know the torque spec. We called SPC and were told that they should be locked up tight at 120lb of torque. However, we don't really trust the design, so we went ahead and use extra bolts to get them locked up. I would HIGHLY recommend whoever is going to install the kit should get them locked completely!
Anyways, this isn't a very good design, but it's ok to live with for now.
- SPL rear camber arms and lock bolts: I'm very happy with the fact that SPL is having the lock bolts for sale together. They work perfect.

Cons:
- AT tranny/ gear ratio: again, the tranny sucks!!!

It wouldn't allow me to down shift from 4th to 2nd. So I ended up driving the car in 3rd and 4th gear for the entire course for whole day. The gear ratio is wired too, no power at 4, but too short in 2nd gear. The biggest regret for me. I would buy a manual if I were to buy it again.
- RE050A: again, these tires no good. However, they do providing very good feedback.
-Exhaust note: stock exhaust doesn't make any sound under any sort of situation, its quiet like you were in a luxury car. I had to look down on the rev all the time. For several times, I thought the engine couldn't rev.
- Fuel starvation: it started at 4/10 tank of gas

Pros:
- stock Nismo shocks and Eibach springs: the compression and rebound both feel well, no cheap feeling or too much travel.
- Tranny: upshift is as fast as Lambo e-gear on 06-08 Gallardo, very good
- Amuse: I'm not sure if it helps anything, but the kit looks awesome to me!!!

car looks sweet on track!

I think you'll notice a positive difference when you get on something besides the 50's...but fuel starve will come in sooner. Time is pretty solid for the setup

Thanks. Maybe my 050's are just too old, they are 08's. I always thought Re050's are decent tires for DD and light track.
I could have done in 1:26 range if I have manual. Actually, I'm thinking of trading it in for a proper manual Z. damn it

the regular 50's come up a bit short on track. The pole positions are slightly better, but even then, most recent tires will outperform.

I've never had the chance to run an auto hard, but I'd heard they were better on the track...sorry to hear it's not working out right. You might talk to some of the shops about getting the trans tuned, I know some have had good results with that.

I have been asking around who can perform the TCU tune, but nothing positive yet. Upshift is OK, it shifts very smooth on straight (can't upshift when cornering).
The biggest problem is downshift. The TCU wouldn't allow you doing anything else with downshifting at the same time, so I have to finish braking or corning or whatever I'm doing before downshift. Such a stupid tranny software Nissan put in here.

Ricky-Thank you for all of the valuable information. I really appreciate you going out of your way to help all of us out. You're set-up is very admirable, and I love all the progress you have made in such a short period of time! Godspeed my friend!

gtkiller · 11-07-2011, 03:29 PM

It's really too bad the auto tranny is holding you back, maybe it's time for that sequential shifter haha... How did the the SPC camber arm hold up? No problems with it slipping?

Haha, I wanna get Leo's sequential gear box when the shop opens. BTW, I just updated the SPC review.

Amuse parts are meant to be tracked. No worries!! Come on out and you will love tracking your Rin.

Update 1: Tires
The pics pretty much explains why I had no grip at SOW. It seems either these tires passed the usage period or not dedicated for track use.

Update 2: Spacers and loosing lug nuts
I had my 15mm spacers installed at ACG San Diego, if you look back my journal you will see I had complainted about the lug nuts kept coming off. I apologize for the mistake and false complaint. The reason why the lug nuts kept coming off was due to they used the incorrect bolts as you can see from the pics. Basically the stock stub against the wheels, that's why. All I wanna say is WTF!!!

Update 3: finally my own shop is up and running so i can do all the works together. I will have more chances to do R&D for track in the future.
