Hi Chaps,

 

Can I just run this past some way-more experienced eyes? :bow: Just to see whether I'm working this out right for the Rota Grids (18s) that I was looking at.

 

Working from the standard sizes [Front 16 x 7.5 45mm Offset and Rear 16 x 8.5 35mm Offset] I'm thinking for 18 x 9.0 Fronts with an Offset of 25mm and 18 x 9.5 Rears with an Offset of 22mm would give the following;

 

Front Inner Clearance of +1mm and Outer Position of + 38mm

Rear Inner Clearance of -1mm and Outer Position of +26mm

 

IF that does sound right, would the increase of Outer Position warrant any arch rolling / flaring do you reckon? I'm thinking that it wouldn't but hey, I'm still relatively new to zeds.

 

Cheers for the sense-check :thumbup1:

A better way is to compare against some known offset and widths that provide a flush fitting without arch rolling.

 

Front : 8.5" ET20

Rear : 9.5" ET35

 

This is about the maximum you can fit without requiring any arch mods or stretched tyres. You may be able to squeeze a little more, depending on tyre brand.

 

Based on those, your fronts will extend an extra 1mm (perfect) , and the rear will extend a further 13mm (Would need some significant arch rolling/flaring and probably a tyre stretch or silly camber :no:). Look at going for a 35 offset instead to avoid this.

You see, that's why this forum rocks. Cheers matey, that's exactly the advise I was looking for to avoid wasting my hard-earned on flea-bay :thumbup:

As Dave says the fronts are bob on. I have 9.5 ET25 on the rear of mine and they fit but my arch has been rolled flat, the one's you're looking at would protrude an extra 3mm. With the right choice of tyre and camber settings they would fit, but certainly not without minor arch work. Funkysi has 9.5 ET25 with only a minor lip roll and wider tyres than me and his fit (curve ball)...

 

IMO, Rota Grids of those sizes would look the nuts!

Aye. ET25-effective here on a 9.5" wide wheel. I'm running 275 x 30 on a 19" wheel on the rear. Only a mild drop on Tein S-tech however.

 

 

Have a look at this.

Cheers. I'm gonna put that down to many, many hours spent scrolling through facebook looking at z32s :-/

They do look superb and very "factory". I really like that you've not gone mad with the drop. Looks just right. Do you reckon that your ET of 25 works with the 19s (that doesn't seem quite so easy with 18s?) or is it just the right tyres and camber?

Thanks. :)

 

It's a combination of everything over the years. I have fully adjustable camber on the car and spent quite a few years playing about with offsets and tyre and wheel choices (I've ALWAYS felt and strongly believe that all the Z32 needs is a nice stance to set it off and little else). I've gone as far as I think I can go with it now and pretty happy with how it sits and its overall stance. I kinda like the 'OEM+' concept and it's nice to have a slight gap between arch and tyre (that's equal all round) rather than tucked underneath. Here's a side view showing the drop and the equal gap between arch and tyre.

 

Wow. Now that's the picture I'm going to use to set up mine (hope you don't mind). There's a place for "slammed" cars and "battle stance", whatever that actually is and I do get what they're going for. But the sacrifices in use-ability of the car are too much for me and anyway, it turns the cars into "show ponies" and instinctively I always think cars should be used.

 

The thing most forget is that going for "OEM+" is IMO, always the hardest to do and get right. The bottom line is that the setup needs to look right AND work right in all the circumstances you (the owner) have chosen to put it through.

 

But with reference to your car, the old engineering phase fits nicely - "if it looks right, it probably is right!.

Thanks and feel free to use it! Hope it proves some use to you in your quest! I completely mirror your other comments too.
