Took your advice and went stiffer. 18k front 14k rear. Interested to see how the digressive shock, custom swifts with matched valving and pillowball Shock mounts do compared to the KW's. Have my appointment for corner balance and alignment in a few weeks. I will still be daily driving the car a bit, but it's slowly winding down. So in the past I went with -2.5 front -1.8 rear camber. Deciding between -2.8 front -1.8 rear or -3 and -2. I'll be running a square OEM rear Rays setup with 295/30r19 R888's. Not sure if I'll have fitment issues with the front but I know I've had a 295/30 Hoosier A6 on the OEM 19x9 with no rubbing. Any suggestions to what I should do for alignment settings?

Still sorting mine out to be honest. Last season I ran ~-3.0 front, ~1.5 rear.

So I stumbled in to an AutoX today, it was an event in Savannah (SCCA Buccaneer I think) I found online yesterday, so I was a bit under prepared....

My Z is 100% base stock 7AT, I looked up the class I should be running online as I signed up and I ran B Street.

We were given six runs... So I had room for improvement, especially as a n00b.

First run: 62.019 VDC On

Last run: 55.421 VDC off

5/9 B class finish, Cars beaten:
Boxster
Corvette
Boxster S
S2000

So much fun. Think I'm addicted. I liked B Street but I saw some 350s in ST(?) Classes so I might try that next. Will post videos when they get to me.

Be careful. Autox can be a very addictive and expensive hobby.

Keep your car in B-street for now. More competitive and since you're limited on modifications you can do, it's cheaper. Trust us. lol

So, for my future reference, looking at the 2016 guidelines (shopping list) for B street:

13.2
-A,E: I can get paddles for my convenience.
-G:Roll bars can be bolted or welded in, cages must be bolted
-I: I can add a rear trailer hitch.

13.3
- Any tires that fit the OEM wheels and fenders are OK.

13.4
- I can use rims +/- 1 inch from stock. Spacers are OK, but iffy.

13.5
- Shock absorbers.... No idea... Help?

13.6
- I can get new pads, and should probably upgrade to the oem sport brakes.

13.7
- I can use 1 aftermarket bar. Any bushing material is permitted.

13.8
- Suspension... pls help?

13.10
- Does this mean I can use a cat-back exhaust?

Bridgestone RE-71R 285/35r19 square on OEM Rays 19x9 front 19x10 rear rims is your best bet here. You can get a set of those for $600 on the forum if you're patient.

Basically Koni Yellows are your most reasonable choice here. Won't break the bank completely, adjustable, quality shocks. Can't change the springs though.

Hotchkis front sway bar, OEM rear bar. Again something you can usually pick up cheap on the forum.

And yes you can use a cat-back exhaust. Not much else for power mods or that'll bump you up a class. STR sucks for the Z because you're limited to 255 tire size which is nothing for such a heavy car.

No reason to get a roll bar or cage just for autox.
Trailer hitch is completely legal. A lot of people have little utility trailers to get there autox wheels/tires to the event.

IIRC spacers are illegal in stock class. Last I knew there were very specific rules regarding what limited deviations from stock wheel offsets could be. Allowing spacers would fly in the face of that rule.

My understanding is going to oem sport brakes would be illegal unless you swap everything that makes a sport model a sport model. It's an all or nothing type proposal.

As far as pads go I'd recommend Ferodo DS2500 pads.

Won't the change in width from Base to Sport wheels knock me out of BS?

Yes, just kee the stock 19's and run the re-71. I run rs3's right now on stock wheels and kee top pax almost every event, koni yellows and eibach front bar with hawk pads waiting to get put on

You cannot use the the sport model wheels and stay in B-Street without putting every sport model feature on your car.

Ok, I didn't see that he had a base car

My highest priorities right now are taking care of grip and body roll. Researching now if 245/275 tires might fit my base rims. Koni yellows are going through the home approval process, but I had to concede the CF paddle shifters.

Here's video from our first points autox event of the year. I think the 370Z can still be competitive even though it's moved up into B Street last year. It might depend on the course. We have several drivers who run corvettes and S2000s in BS in my region, several of whom are nationally competitive. I guess we'll see as the year progresses.

1st in BS, 3rd PAX of 131.
