Look at dagon68's thread from 1.5 years ago:

LOL at finding myself all over that thread, too.

The point being, now I'm seeing his Before/After pictures with personal relevance. I'm going to repost them here for reference. Look at the rear wheels in his Before pic. That silly poke in the rear... that's exactly what's making me go all Chicken Little these last couple of days.

Eibachs are another option in the milder drop catagory.

As far as lifting the G, I'll try and get several shots, one at stock height, one about 3/4" down like the Nismo, one about an inch, like the swift, and another at 1.25" like the Eibach. Hopefully it'll turn out like expected.

 

OK here goes, just checked my alignment sheet and the drivers side that I'm posting has very little camber -0.06 degrees and toe of 0.08 so this is a very straight tire, your tuck should be a fair amount more w/ double the camber, so that should be even better for you. The straight down pics weren't taken completely straight down so the poke is a bit exaggerated, at 1" drop the poke is gone from what I can tell.

Stock height, or close to it (measured 28" from the ground to the highest fender point)





Dropped a half inch to 27.5"






Dropped an inch to 27"






Dropped 1.25" to 26.75"

 

That's fascinating. Thanks for the experiment, Brad.

As you maybe can tell from posts today, I'm strongly considering a set of Swift RWD Sedan springs. With only 0.8" drop in the rear, I doubt the poke would go away completely like it does with your full drop. But probably good enough to keep me from making a fuss like I have. Plus, the changes in gap will change the overall perspective, so there's that, too.

I PM'd N4S for a quote.

 

Well you're at the worst height for poke so at almost an inch lower you'll be in pretty good shape, and like I mentioned your camber will be more negative than mine so I think you'll be pretty flush.
Swifts are consistently reviewed as the closest to OEM ride so you shouldn't have any major surprises there. Wish I was close by, it would only cost an afternoon of premium beer for the install. If you haven't done any spring swaps and have questions just PM. With your network of friends in the sedan meet-up I'm sure someone could lend a hand.

If I had a friend like you close by, I'm sure I'd be doing a lot more DIY projects, Brad. Closest friend I have who could knock this off for a six pack lives three hours away. As it stands... I'll just be going back to the mechanic. He's a good guy, he's got skills, and he's very fair.

I suspect our rear springs are pretty easy, right? Seeing as how they're separate from the struts.

 

The only thing that was a bit of work was the front lower strut nut, but a 2 ft breaker bar and some PB blast and it broke free w/out too much work. Rears are a snap.

 

$314 shipped. That seems like a crazy good price. However, I still hit up two vendors here for a quote.

Brad, if you decide to fly in for the Northeast meet we'll make sure you get an afternoon or evening of premium beer. And a good cigar if you are so inclined.

Watching this was pretty fascinating for me, a good opportunity to see what the dynamics of change are.

John, I think if you go the Swift route you'll be much happier with the look and handling if the car. I'm looking forward to seeing which route you go, thank you for always discussing your thought process with us. The perspective is always interesting.

 

Yeah Brad, fly out to Rochester NY and ride down to the meet with me.

 

That would be a blast, but I'll just be rooting for you guys from the sidelines
Sounds like a nice price on the Springs John, nice that you have a trusted wrench-turner to do the job.

 

Thanks for doing this Brad! Since nobody is close, I guess the best we can do is slide you a virtual beer...haha! Great experiment to see how much an impact that the ride height has on the car. I learned quite a bit from this.

 

+1 on impressions and review of the Swifts

 

We could easily get the spring job done for him in the state park,haha. I have an electric impact gun that could easily get the job done. Then you can get an alignment when you get back to NY.

Brad you should totally fly in - it would be great for you to join us!

 

A few days after mounting the VOSSENS, the TPMS sensor came on. It flashes when starting the car, then goes solid lit after a little bit. I would really love it if our cars told us *which* sensor was out of range, alas...

So I checked the tires with a decent gauge. All four were at 32-33 PSI. Then I checked my duckfeet with snow tires, and all four of them are at 32-33 PSI. The original TPMS sensors are still in the duckfeet. The VOSSENS have new NISSAN sensors installed by Need4Speed.

So I pumped each of the new tires to 35 PSI, drove around, and no change.

The TPMS Reset DYI is really complex. How about if I just disconnect the battery? If I were really going to just live with a lit TPMS warning light, then I wouldn't have bothered spending money on sensors. So this is where I'm at. Anyone have some good advice?
