There are two different part #'s. The spec-R are the only ones for the 370Z. The others are not for the 370Z.

Spec-R part # 4N905R off my two sets still sitting in the box in the garage.

So I just installed the Swifts a couple of days ago. I'm using a 20mm spacer setup in the front and 25mm on the rears with the OEM 19's. I'm going to get an alignment soon but not sure if I should just get some camber arms and get it over with before I do the alignment. I'd like to try to avoid camber arms if it's really not necessary. What's acceptable as far as camber goes for the fronts and the rears? And if anyone knows, how do spacers affect the camber specs as well? Thanks for the help in advance! :D

The best my dealer could do was take it close to -2.5 camber on both sides. Before it was -3.0. This morning (roughly 1.5 weeks of the springs settling), I wedged a credit card underneath the rear tire and was able to push the whole thing in. :eek:

I did the same test for the front wheels (-1.5 and -1.6), and it barely made it past the roll.

I think I will probably shoot for something close to -1.2 for the rears with the camber kit (not sure about toe bolts) and leave the front wheels alone.

Wow thats a lot of camber.

Yeah you were one of the unlocky ones, you def need a camber kit!

What you are asking has already been discussed in this and othe Swift threads. Most of us do NOT need a camber correction kit. So just do it and get an alignment to see if you need one...

Hey just wanted to let anyone in Socal know that if you're looking for a good alignment shop, West End Alignment in Gardena Ca did my alignment and these guys are seriously top notch. They actually have you sit in the car the entire time while they do the alignment to account for your weight. I have a rear camber kit on my car but no front. Im actually curious to know how they adjusted my front camber. My car drives like an absolute dream now. I thought it drove good with the swifts and whiteline sways before. I was blown away after the alignment. Absolutely no bump steer and it does not pull one way or the other.
Here are my before and after specs:
Before:
Camber
Front Left: -1.9 Front Right: -1.5

Rear:
Rear Left: -2.2 Rear Right: -1.9

After:
Front Left: -1.75 Front Right: -1.75
Toe: 3/16th
Rear Left: -1.75 Rear Right: -1.75
Toe: 1/16th

My alignment specs were pretty much on par with yours, -1.5, -1.6 in front and -3.1 in the rears. Stock specs have a -1 degree difference between front and rear so the guy at my shop recommended I follow that to keep the handling similar to stock. Toe he was able to get in spec.

So right now i'm at -1.5, -1.6 front and -2.6 on the rears. I don't think I'm going to get a camber kit as I don't mind the current alignment and the car handles fine for me. It might be a little on the high side but it's fine for me.

Heres a question.. Is anyone running 40 series tires in the front and back? I love the swifts but I just want to reduce a bit of the wheel gap all around. I fell like 40 series tires would have no wheel gap front and back, but I don't want to mess with the dimensions too bad.

Ditto on the toe spec. It makes a lot of sense since we have the same spec for the rear wheels. Our front wheels are technically the same (10mm spacer gives it an equivalent offset). The 305s are begging for more contact patch since it is literally riding on half of the tire width.

SPCs ordered a couple hours ago... hopefully there's room to make it close to flush with the fender while keeping camber slightly on the negative. :tup:

One down and one to go in the morning. First impression ....like a freakin go kart.

Does anyone know who has the swift springs in stock? I don't like to pay of parts and wait for them to "arrive". Some many vendors too little time to call em all. Just asking.

Kami Speed had them... not sure if they're sold out.

KamiSpeed is sold out and taking orders for the next container from across the pond.

Hey PJ, it would make your speedometer less accurate as you are increasing the total diameter of the wheel but as far as performance is concerned, I doubt it would make a difference.
