Quick question, going to look at a set of racing hart alloys, there 18's 9.5 inch all around and offset is 28,how would these fit on the z?

They'll rub. Not too far out of max spec. Rear lips will need rolling and the front arch liners may catch.

I reckon they will look very nice. The rear arches will need a lip roll, amount dictated by tyre choice/camber. The front will be nice and flush but they will likely rub on full lock at the front, inner arch.

What wheels are they by the way? Racing Hart do some very tasty wheels...

Thanks for the help lads, iam useless when it comes to offsets and wheels.. There racing hart cx 5 spokes, I've only seen pictures of them, they need a full refurb, going to view them in the next few days to see what there like. Mite work out cheaper to just buy a clean set..we'll see!

A very nice wheel indeed and super rare to find in any condition. If they are specifically what you're after, get them (depending on cost)!

 

As a rough guide, here they are (albeit a 19" version, but you get the idea). I believe they are 19x8.5 et36 and 19x10 et43 but I'm not 100% sure as the rears look like a lower offset: http://awesomesaucelifestyle.com/feature-1990-nissan-300zx-twin-turbo/#jp-carousel-1389

 

The offsets of the wheels you are looking at are much nicer.

 

There are lots of images of an old member on here called James300 aswell with these on (and another user who bought his car which I forget!): http://www.300zx.co.uk/forums/showthread.php?49742-My-new-wheels
