About to order another pair of 19x10.5+30 wheels it looks like so I can have perfectly even fitment and cross-rotate my tires so I get the most life out of them. I'm going to do a final test fit this weekend to see how they compare front to back with a 19x10.5+30 on each. I forgot to compare the 10.5+30 up front to a 10.5+30 on the rear when I test fit them a week or so ago. Hoping it's even front to rear but might need to use my 19x10.5+23 rears to make it just right visually; 99% sure I'm going with 19x10.5+30 all around. Lowering my front coilovers about 1/4" should help even it out further. Once that's done I'll definitely have either a pair of 19x9.5+23 Work Emotion ZR10 wheels for sale, or a full set in 19x9.5+23 and 19x10.5+23.
Test fit the 10.5"s on the fronts again. Glad I did because I realized I'll need some SPL fuca's finally if I want to run the 10.5"s up front and not have 0 degrees of camber, lol. They poke more than the rears at the moment, but going 1/4" lower in the front and adding -2 degrees of camber with aftermarket arms should do the trick. Almost even front to rear otherwise...still contemplating running the +23 rears and +30 fronts but that would defeat the purpose IMO since I wouldn't be able to cross rotate. Answered my own concern. I'm going to make the 10.5+30 square work.
Still trying to unload that Stillen intake manifold and the 4.08 R&P if anyone is interested, both are listed in the classifieds. Hopefully I can find someone local willing to trade exhausts or swap me for an OEM exhaust + cash at least. so I can finally test the sport accessory muffler paired with my AAM resonated HFCs and some sort of custom/aftermarket mid and y-pipe setup. If you're in SE Florida shoot me a PM.
Two new Work Emotion ZR10 wheels are on the way, 19x10.5" +30 square setup is about to live. I don't want to spend the money on the Yoko's I want at the moment, so I'm going to run a set of 275/35/19 tires on the front wheels until then- working in a shop has a few nice perks like free mint condition used tires. Some of the Genesis tires our customers run are very nice options (a lot of Michelins) esp here in SE Florida where most people run summer tires 365 days out of the year. This works until I get camber dialed in...tires are close enough to the 285/35 I'll eventually run. This way I'm also not destroying a set of new tires in the process.
I'm going to see if I can lower the front coilovers another 1/4" when the new wheels get here. Hopefully I have enough adjustment left with the OEM camber arms to add a hair more negative camber if needed. Excited to see how it all looks.
Sold my spare set of Work Emotion wheels to a coworker with an 04 350z before the fronts were even off of my car. Very happy to see them go to a good home where they will be enjoyed and taken care of. The 9.5+23 fronts and 10.5+23 wheels work flawlessly for the 350Z.
I grabbed some Bridgestone Potenza Sport tires on close out, too good of a deal to pass up even though I’ll have mis-matched front and rear tires for a little bit. They are 275/35 instead of 285/35 since I realized I don’t like taller tires. I’ve barely driven on my 285/35 rears so the wear difference should be spot on with the diameter of the narrower 275/35 front tires. This will also give me a little more safe leeway getting the front height and camber dialed in, and avoid any potential rubbing.
Eventually I’d like to run 295/30 square but we shall see. The fronts would cause a small speedo error, so I might discuss that with my tuner. It might not be a concern for ecutek. The 10.5+30 wheels are also already very close to the suspension strut so I’d have to measure tire clearance first. But since I’d be running a true square setup, I shouldn’t have any slip/VDC issues.
I already know I’m finally going to need upper control arms to get camber dialed in where I want with the 10.5s- So I’m debating between Z1s new forged FUCAs or time proven SPL for a good bit more $$$.
The wheels arrived in perfect shape, tires will be here this week sometime, and I’ll be mounting everything as soon as they come in. I mount and balance my own wheels and tires, it’s very rewarding, and I have no excuse not to working in a shop. For someone OCD like me it’s also heaven knowing exactly how everything is setup. Only person I can blame is myself if anything goes wrong.
Square setup lives. 19x10.5+30 square works without rubbing. I don’t think I can run anything wider than a 275/35 on the fronts..it has 3-4mm of clearance between the tire/edge of the rim and the steering knuckle. But it works with no issues. I really like the way the Bridgestone Potenza Sport tires fit; they actually have more of a square sidewall vs the current Yokohama Advan Apex v601 285/35/19 rears. That surprised me since (according to tirerack and their “accurate” tread width measurement) the 275/35 Potenza’s should have actually stretched a little more than the 285/35 Yoko’s, 9.4” for the Potenzas & 10” for the Yokos. The Potenza’s look so good (my personal taste/opinion, my car) I’m going to swap the rears out to match. Then I can fully rotate tires. 275 of tire is way more than enough for a N/A G, and 285/35 looks a little chunky compared to the 275/35; it is a hair larger in diameter @ 26.9” vs 26.6” for the 275/35. The 275/35 tires also weigh 2lbs less each vs the 285/35 tires. Every bit of rotational weight savings I can jump on I’ll take. Still need to get floating (“2 piece”) rotors at some point in the future but I’m not rushing that with mint condition brakes right now. For anyone curious, the 10.5” works only needed 1.5oz and .75oz of wheel weights, respectively. I balance my own wheels and tires…it’s more rewarding than the instant gratification one gets from mowing the lawn.
I will still plan on lowering the front suspension about 1/4” more after I swap to 275/35 rears in a few weeks for even height measurement. I also 100% need aftermarket FUCA’s to add some negative camber up front…looks like maybe -1 degree of camber right now. Alignment is still spot on though. It’s been so long I forgot what my specs are after “remembering” it was -2.1 all around a couple years ago, months after an alignment was done with no sheet given to me since a friend of a friend did it as a favor.
The tramlining I previously had is a thing of the past. This thing is really on rails now. Very predictable steering, and a freaking boatload of fun in corners…. Doesn’t feel heavier etc., the wheels only weigh 24lbs each even at 10.5 for a flow forged wheel, so still saving weight over OEM 19x8.5 fronts that were over 26lbs a piece with heavy factory tires at around 31 pounds per tire, IIRC. Worth every penny for me. The 19x9.5+23 19x10.5+23 set has already been sold and going to their new home where I know they will be smiled at the same way I did every time I walk to my car since getting those wheels. They will be going on my coworker’s 2004 350z roadster in silver stone metallic that has been very well kept and has some light modifications done such as BC coils and a Greddy single exit exhaust. I’ll see if they are cool with me sharing a few pictures once they get the wheels mounted this weekend. I need to detail or at least wash my car and clean up the tires before posting any pictures of the 19x10.5” square setup, but I’ll upload something by this weekend for anyone curious how it looks.
Oh, and I FINALLY installed my project kics duralumin hub centric rings and feel much better having them on. Do it right, safety first. Part number KICS-WU7366 for the 73 to 66 hub centric rings for Work wheels and our hub bore, only $20 a pair from a bunch of online retailers.
side note - got some Aodhan wheels for my BMW f30 328i and love ‘em for the price. Balanced out fantastically, paired with General G-max RS in a square setup (wheels & tires). I definitely recommend checking them out if anyone is hunting for some nice flow-forged wheels at a decent price.
If any experienced track rats want to share their caster settings, please let me know what you run. Planning to set front camber at -1.9 to -2.5 max (for street) and rear to -1.9 to -2.1, still digging into optimal caster degree- debating between the new Z1 forged front upper control arms or SPL’s FUCAs. The SPL has adjustable caster but the Z1 doesn’t and is permanently set to 7.5 degrees of caster. Curious what other track rats run for caster settings, if you have SPL arms. Sounds like with less camber the Z1 arms would work nicely.
Have you considered partsshopmax's offerings? They are the only manufacturer I found that makes front/rear control arms, camber arms, and drop knuckles. Everyone else only seems to make half of the parts and I am not sure if I wanted to mix and match, but purely for aesthetic reasons.
That being said it looks like the Z1 forged offers the easiest adjustability at the lowest price, I'm a big fan of pinch bolts to not have to crank down jam nuts... And it appears that they can adjust caster in the same manner as the SPL if you get the race versions ($20 more than street version) because those come with the heim style joints rather than the bushings.

Thanks for that, I overlooked that fact about the race version when I read their release email. I wouldn’t even consider the street version, personally. NVH sign me up, lol.
I’ll probably definitely give the race-version Z1 forged arms a try on that note. Price point is much more reasonable for what the product is. I love SPL but with inflation already expensive things have gotten crazy pricey.
19x10.5+30 up front with 275/35 Bridgestone Potenza Sport tires all around. I need to add a hair more negative camber up front. Around 5mm of clearance between the spokes and caliper, but they clear safely. I’ll probably lower the car another half inch all around soon enough. Really want to rid that fender gap for good.
