Upgrading to GT4 Rims


DarmoZ

Recommended Posts

I have the standard 18 inch wheels with stock 225/45 front and 245/45 rear.

 

I have seen this set on Gumtree of GT4 Rims and I am thinking to upgrade:

https://www.gumtree.com/p/wheel-rims-tyres/nissan-350z-limited-edition-gran-turismo-4-gt4-alloys-hydro-dipped-wrapped-18-alloy-wheels-x5-unq/1136331963

 

Stock spec of current wheels/tyres are:

225/45R18

245/45R18

8.5Jx18 ET27

9Jx18 ET27

5x114.3

 

The new combination will be:

225/45R18

245/45R18

8Jx18 ET30

8.5Jx18 ET33

 

My question is would these fit my ZED OK?Does the difference In wheel width (J) and ET make much difference? If so should i use a different tyre size.

 

As you can tell this is my first time venturing into the the world of changing Rims.

 

Thanks 😊

Your wheels wont be standard if they are 8.5 & 9's and offset of 27, std rays are 8 & 8.5 et 30 & 33.

 

That aside those wheels will straight on as they came of a 350z, although they are considerably heavier than std Rays if thats what you have.

I was going of this guide which says those are the numbers for stock 18 wheels: http://www.wheel-size.com/size/nissan/350z/2004/

 

Haven't actually gone out to the car and had a look, I'll go and check If there are any markings. I don't have the Rays, I believe they are a optional extra, I have the stock 18s, here a recent pic of my car: e3e927cb62e684292b8b7ad1c7459c16.jpg

Sounds like these shouldn't be an issue since they came of a ZED in the first place. I'll see what I can get him down to and mention I don't need the 5th. He should include the key nut aswell right?

So the new wheels and MPSS have been Installled, really happy with the look and the handling has been transformed, taking corners at speeds not possible before, they haven't even worn in yet :) Michelin currently run a promotion where you get some money back in the form of fuel vouchers, I'm getting £50 back, promotion runs until end of November.

 

P.s. Tyre Barn set all 4 on 32PSI stating this is correct, sounds a bit low to me, what do you think?

Thanks I'll set them to 35.

 

35psi all round is standard on 18" wheels.

 

whats the graphics on the wheels? did the previous owner have then hydro dipped or something?

Yeh he did, I think it's like tribal art or something, not too sure looks cool though :)
