It was really easy to remove mine. my battery powered impact was able to get those out easily. try compressing more?

Appreciate the diy. Helped with rear swap of Nismo springs, don't have compressor though for front.

I just did my 2013 NISMO. I installed an Ebaitch Pro Kit. I did not put in cambers, because it doesn't really need it.

With the Pro Kit, it's a 1" drop in the font, and .5" drop in the rear. It took a little under 2 hours with a lift, and proper gear (impact gun). As well, there was no need to rebalance the tires, as the drop wasn't great enough to call for rebalancing. Like the original poster stated, the front was taken to a local shop where they pulled the springs out, and replaced it with the new springs. Disassemble and assembly in and out of the car is the easy part.

PS. The picture with(OUT) tints is how it looked prior to putting in the Ebaitch Pro Kit, and the picture WITH tints is how it looks after the install.

Check the wheels again in a couple of weeks, I thought I didn't need to upgrade the camber arms, but the tires were really wearing fast from the inside which was really difficult to notice if you don't throw yourself in the ground and check them.

Kab,

Thanks. I'll do that. I had a 350 NISMO, which just got flooded (water dam broke in NJ after the rain storm a few weeks back) and the rear tires use to wear on that car pretty bad.

Never the less, I'll see how the 370 holds up. Here's a pic of the 350. I miss it, but the 370 is pretty awesome, too.

Hey guys, I'm in a pickle. I was removing the 3 strut mounting plate bolts and I rounded one of them. Does anyone have the part number for this bolt? I went to 3 different dealers and no one seems to be able to find this mystery bolt. I went ace hardware and got a matching 10.9 grade bolt but I'm unsure if it's strong enough for the job. Help me 370z forums, you're my only hope!

don't use a bolt that's not meant for that.

seach Nissan USA eStore

should be easy to find anything you need

I spent last few days looking at those diagrams from various websites. Even drove 60 miles to visit more nissan dealerships. We all came to the conclusion that nissan did not put a part number on the diagram for these 3 bolts and the mounting bracket. I couldn't find the torque value for these bolts in the service manual either. It's a mystery. Dealership said I should just order the A arm, I'm not paying that much for a bolt.

If anyone can find the mystery bolt, please post up.

Word of advice for future DIY out there, don't round off your strut mountng bracket bolts.

aszyd · 07-21-2014, 06:56 PM

I have to agree. I tried looking at parts diagrams as well and I can see where the part is supposed to be, but there is no part number for the plate, or the bolts. You can get the suspension out without removing those bolts, it just takes a ton of work to push the arm low enough to pop the strut out.

which ones are those? The ones for the front suspension you reach throw the engine bay? Take a picture if you can...

Minhtin · 07-21-2014, 11:28 PM

The lower part where the strut mounts to. one side is the arm itself, the other side is a black bracket with 3 bolts. You can see the pictures on the first page.

For those that do end up breaking these bolts, you can go to Ace hardware and get yourself a grade 10.9 M10 X1.25 bolts. It is exactly the same in almost every way, except for the fact that it's shinier.

Minhtin · 07-22-2014, 03:25 AM

Yes those three bolts.

Austonian · 07-22-2014, 12:39 PM

Has anyone tried removing the rear bumpstops or possibly replacing them with something else to get more of a drop in the rear?
