Drove to work on dry roads with new rubber (Kumho PS91) on 19" coupe wheels, 245/275 proper ratios. Smaller diameter than the POS 20"s that were on there at 225/35 and 275/30.
increased torque from smaller wheels I did not expect to be much but wow. Also poly differential bushing wow in driveline response (used to sound like the diff was slapping the underside of the car when I hard shifted). And the FI RHFC + Catback oh my god this is better than a canadian mistress. Dat burble.
I'm still undecided about the ebay short shifter. With tweaking it works fine and the shifts are very small and precise. But I don't really feel like it was sloppy before. I think I got my desired 15-20% reduction by putting on the smaller shift **** that sits about 1" lower than the stock one.
Definitely need an alignment and new rear swaybar links.

IDK what ebay shifter you're talking about, but the TWM STS is still one of my favorite mods.

With wet roads I needed to keep it below 1800 RPM or I'd get wheel slip. Above 3k RPM I'd get wheel hop. On dry roads this morning it was wheel hop about 4k+ unless I rolled into it super slow.
Normally I'd think tires, but the PS91s are summer UHP, are brand new, and generally rated well. It's not because it's winter either - been consistently in the 70s here. They certainly have more tread than the 275/30R20s I pulled off the back that had steel belts coming through.
I wonder if the TPMS throwing an error could mess with TC? I haven't been to a dealer to learn the new TPMS senders yet.
... yeah, it is pretty fun. The poly diff mounts should have been part of the infiniti Sport package.

For the longest time, 4DRZ was experiencing unhappy wheel hop, too. I think the rear diff brace helped.
I don't experience wheel hop. Not at all. It either hooks up or it spins, entirely up to clutch engagement and my right foot.

It's not horrible like Jeep death wobble. Also, while under the car it really looks like the suspension is all original - struts, springs, sways and links. I know the swaybar links are toast. I wouldn't be surprised if other parts are too.
With the lower rear gear I'd imagine you'd cross the hop threshold pretty quickly and go straight to spin. Hop is a weird problem of enough grip to go but not enough spring pressure making it stay on the ground.
Edited to add: I'm still being a little bit of a pu**y with it because I know the exhaust needs some break-in. Did the FI cat break in, now working on the 5 drive cycles. And the alignment is wobbly as heck - I don't want to spin into a jersey barrier trying to pass a semi.

Also - found these, which look like they'd be a good replacement for the oem rubber:

I compared the mazda rubber ones to the infiniti ones and they are the same unless a different rubber compound.
I probably need new/beefier rubber mounts for the rear of the exhaust.

Those first few weeks with the gears, though... wow, what a rush.

You know what? You've been here for a while, with mods and comments. So I moved your intro into the Build Threads. Seems like a reasonable jumping off point.

Got the Kumhos mounted and put the front Coupe Sport wheels on to replace the spare and other ailing tire. Was going to try to get at least one coat of plastidip on the rears but it looks like it will be wet over the whole week.
On a similar note, found my old Air Force goretex top and bottom so I will be putting her on stands and starting the exhaust and diff mount tonight or tomorrow morning.
Question: 2013 Sedan, I need to get Infinity to use a Consult computer to learn the new TPMS sensors, correct? Not a Nissan dealer, not an aftermarket shop?

If the TC is mainly kicking in during cornering or on corner exits then you can also try using a slightly softer setting for your rear sway bar, assuming you have adjustable sway bars. This should help reduce oversteer.

Suspension is all stock 60K infiniti 6MT. For now. Swaybars are on the list but money's been tight, we had a big trip right before Christmas and and and.New shocks might be called for. The swaybar links in the rear are worn as I'd be comfortable with without being dangerous.The car does need an alignment since I think I have toe out on the front and too much negative camber in the rear (see pic of tires above).
