Heya All,

I saw this for sale recently:

4 stud to 5 stud conversion spacers (25mm thick) to suit 4 x 114.3 PCD Cars (S13, Older Toyota etc.)
$Aus.695set

See: http://www.japanesemotorsport.com.au
And also have a look at the Equip and Works 5 stud mags. I love the look of those Equips!


Now, 4 to 5 stud conversion I get. Being 25mm thick, does that mean that the offset will increase to 33mm?

Is this a good thing?

The extra 25mm of offset will give you a better selection of wheels. You'll pretty much want to be looking for wheels around 25mm of offset now. What is the 5 bolt side bolt circle, 4.5, 4.75, 5 or ? . If it is 5 x 4.5 (114.3) you may have a hard time finding 25mm offset wheels. Its a common modern import bolt circle and usually comes in 35-50 mm offsets for FWD cars these days.

Umm, what does it look like?

Hmmm ... scratches head. Why 25mm?

Thanks for the info SM2! Dja like the look of those Equip. mags?

Dunno about legality, but suddenly a whole world of wheel options has opened up before my eyes!

25mm for offset because generally you want 0 offset for a Mk2 wheel. So a 25 mm offset wheel with a 25 mm spacer will give you an equivalent 0 offset wheel. I would see if you could get a 35-45 mm adapter, especially if it is 5x114.3. Looking at the pic of those adapters they do look like 5x114.3, since they are using one orginal stud. That could be a problem as well since you'll need 25mm longer studs. The longest ones I know of are ~10mm longer. BTW Equips are nice looking wheels but very pricey. You can buy pretty much any wheel you want for what they cost.

Ahhh ... thanks again!

The spacers are certainly pricey. But the Equip wheels & tyres (assuming they are OK) for $1,500 Aus. looks like a bargain. If it would work, this combp is certainly cheaper than getting custom Simmons wheels made.

If you look at my web site you will see that I'm using adapters on my car, but as large spacers so the bolt pattern stays the same and I can fit different wheels. 4X114.3 on the hub and 4X114.3 on the adapter.

You are correct in calculating +33mm offset with the spacers for the new wheel, the factory wheel for the MKII is +8mm. I don't know why everyone assumes 0mm offset for the MKII, it says +8mm offset right on the stock rim?

I do know that using a different offset wheel not close to the original offset will cause abnormal bearing wear, but this is in cars with smaller wheel bearings and I have not seen it in MKIIs.

My best suggestion in wheel fit with those spacers you mentioned is find something that is close to the original offset, I mean a +33mm offset wheel. As you will see from what I've done is that there is really no problem with varying the offset within a range.

I guess by going to adapters (spacers) pick a new bolt pattern that wheels are readily available for, at the offset you need (for best fit) and at a cheap price. If not you might as wheel get custom wheels such those by Simmons or Braid.

I also noticed that some custom wheel manufacturers such as RH and Braid are now making and offering these adapters for sale. Check their web sites, some meet TUV compliance. I assume from this that if they are built and installed properly they should be safe to use on any car.

Thanks for the advice all,

I think I'll look into spacers to bring the offset out to match the S13 Nissan 180SX/Silvia (which are as common as mud in Oz.) - rather than changing the bolt pattern. Should be easier and less likely to draw attention by the constabulary :) too.

If you want a significant thickness in the spacer you're going to have to run adapters (with the 4x114.3 BC on both sides). The problem with straight spacers is you are limited in thickness by the wheel studs. The longest Toyota studs I've found are about 10mm longer than stock. Most adapters come in at about 20mm at the thinnest. I'm currently running the 10mm wheel spacers in the front with these studs. You can see them in this picture here;
