rear wheel spacers for 19 inch 370 rays

[saint]

Hi,

 

I'm getting some 19 inch 370z rays at the weekend, and already have 15mm rear spacers. To save me trying, will they still fit? Car is standard ride height

 

While I'm at it...20mm is the minimum for the front yeah?

20mm for the fronts. Shouldn't need any for the rear.

dont forget you'll need the correct wheel nuts

For the nuts, do I just get any marked as 370z, say the ones on tarmacsportz store?

 

I'm guessing the spacer has to be a 350z one and not a 370z, although some threads say they are basically the same thing. And last question - so should I remove the rear spacers I already have? If they still fit I'd keep them!

With the rear spacers I would remove them personally as wheel sits quite flush anyway. But you can always see after fitting. You may get away with 15mm spacers at the front. Heard some Americans using only 15mm with no issues. Having said that I went for 20mm

Wheel nuts need to be flat seat not tapered like the 350. Nissan part no. 40224 jk00a.

I picked up a set of ebay, not cheap though.

 

Hope this helps

How sure are you, tarmac sportz say their 370z nuts are tapered as are the 350z ones. I dont get how installing them on a 350 instead of a 370 would mean they no longer can be tapered.

The flat seat nuts are specifically for those wheels (and a few others), not the car. The 370Z Rays use flat seat nuts regardless of if they are on a 350Z or 370Z. If you have aftermarket wheels on a 370Z then you would probably use the taper seat nuts like Tarmac Sportz sell.

 

My local Nissan dealer sells the flat seat nuts (40224-JK00A as burgs said) for £3.85 each. The locking flat seat nuts (KE409-89991) are £81.40 for a set of four including the key. Not cheap but necessary unless you can get a used set from somewhere.

Interestingly, the 350z locking nuts go on ok, as do the normal ones, you just have to tighten the life out of them. The seats for the lugs will no doubt be trashed but the wheel definitely isn't loose. To be safe I got 4x370Z standard bolts all round and used the locking nuts that came with the car.

 

A note on wheel spacers in case it helps future people - not much room for spacers on the rear with the 370z rays on, and the main issue with the front spacer is that although 15mm ones do clear the caliper (on mine at least) the nuts holding the spacer on sit proud of the spacer which then clash on the inside of the rim and stop you from having a flush touching condition. 20mm spacers have deep enough holes for the bolts to sit under-flush. I thought I'd try my luck before swapping them over
