VWW Official MKIV Wheel Q&A

9.5 et40 is very very aggressive in regards to inner clearance. You may even have rubbing on the spring seat. Nothing an angle grinder won't fix. But with a 235/40 on a 9.5, it will look a bit funny IMO. You should be aiming for a lower offset. You could get away with et30, or even et25.

Remember that my 9.5 et40 has 15mm more tyre sticking out either side.

+ I hope you are going to be purchasing adjustable rear control arms if you haven't already.

Inner clearance is my biggest concern hence why I posted questions in this thread. I have 18x9.5 Keskin kt4s with a et30 offset and a 235/40 tyre. Did like the fitament but I got defected for it. I now need something that tucks under the rolled guard. My front wheels are 18x8.5 with et25 and they are a good 1" inside the rear guard and look very average. So I either use ridiculously wide spacers or buy new rims. I choose the latter.

I've been searching for a new set for quite a while and its a struggle to find a 5x100 wheel that pushes out to the edge of the guards with the perfect offset. I seen your car with the et40s and they seem to tuck under.
The miros are deliciously concave and I think they look mint as with some stretch. For 5x100s they only come in 18x8.5 et30 and 18x9.5.

How much is a set of adjustable rear camber arms ?

Thanks for that Dylan. $150 is much cheaper than I thought.

What do you mean by "aggressive fitament" ? I'm very new to "stance" and pushing wheels too/past the guards. Would aggressive mean that it would be very tight fit or the wheels/tyre could rub against the guards or the suspension?

If that's the case then I'm a little perplexed as you said your 9.5" et40 wheels rubbed against a canister on your coils (that I don't have).

Like I said before, I just want my wheels to be inside the guards with lighter tyre stretch because I don't have the time nor do I want to spend the money clearing defects.

The wheels im wanting to buy come in 18x8.5 et35 and 18x9.5 et40.
I'm really struggling to get a picture of how it'll all fit and work.

Can I make them work to suit my needs?
I test fitted my front keslin kt4 18x8.5 et30 rim to the back and it was very far from in the guard so the wheel and looked very average. If I was to fit the 18x8.5 et35 variety to the back, what thickness spacers would I need to use to push the wheel out?

Tyre wise, as much as id like too, I can't go 215mm because no 18" 215mm tyre has a high enough load rating of 91 or more (boras load rating).

Do appreciate the help - thanks.

Why do you want to stretch Tyres onto wheels that will sit inside the guards?
Not trying to be rude, but if you aren't willing to use spacers, or don't fully understand offsets, I would go for a wheel that isn't so aggressive. If it doesn't hit on the suspension or inner guard, it will only be mm's away. Will need to consider spacers though.

I quite like the stretch look. Prefer it over bulging sidewalls. But at the same time, annoyingly, I don't like having too much of the rim exposed past the guard.

I do understand offsets to a degree, but not sure how they apply on the 4mos with clearance. The wheels I want (Miro Type111) only come in 18x8.5" ET35 & 18x9.5" ET40 so I assumed I'd need the 9.5" for the back due to the extra clearance. I've not found many Bora 4mos on the internet with such a setup because most seem to be about "stance" than anything else.

I'm warming to the idea of spacers,but I'd probably like something thin for safety purposes. I do track my cars so I need something that holds up to a bit of pressure. My concern is that the spacers could do damage to the diff/hub/bearing or worse if they actually fail.

This is the kind of fitament I'm looking for:


By the sounds of it, you're not confident that a ET40 18x9.5 will achieve this?

[JustCruisn]

^^ wow I likes the rear but not the front.

[RubAVeeDubDub]

^^ wow I likes the rear but not the front.

Yeah love the rear fitament! I'm planning to buy those wheels in Matt black to suit my black Bora

Front would be better with a small spacer and maybe a little bit higher. Could do with a wider tyre as well imho.

Does anyone know if the MKIV R32 has similar rear suspension setup to the Bora 4mo's?

This is a R32 with a 18x9.5" Miro 111 wheel and a 15mm spacer.

If you look at it from the front, I don't think it looks bad.



This guy has used a 18x9.5" wheel on the back with an offset +35. A 5mm spacer should help me achieve that?
I'm guessing being a non-4wd Golf the back end probably has more space than a Bora 4mo?

no point in comparing it to a FWD, completely different game out back.

This is a R32 with a 18x9.5" Miro 111 wheel and a 15mm spacer.

R32 is the same so of clearances as a 4mo bora.

no point looking at other cars unless you know the suspension setup and how low they are.
most of the above will be lower, so geometry has changed so much it becomes irrelevant.

put your other wheels back on, use a offset calculator and a ruler and should be able to easily work out if itll work.
Simons can fit the 9.5et40 due to his car being a bit higher (not sure where yours is at) and his control arms fix any camber, there for giving more room on the inside of the wheel.

check some of the other 4mo guys on here. thestu and kapowww arent running adjustable control arms from memory which will make it similar to yours depending on height

the rear track on a 4mo is about 10mm less each side then a FWD car.
9.5et35 looks about right on the rear of that.

Confused about law in nsw, you can fit only 1 inch bigger than standard?

Car has 16 standard

Although saw this today


225/45/17?

So there was a bora with 17s standard?

yep. 17x7et38 toccatas (spelling?), which were a almost flat faced 5 spoke and bora sports which were 17x7.5et38 if i recall correctly.
Both with 225/45/17s
Not sure why the sport doesnt get a mention on the placard.
Mine is different again to yours as it lists at 15" option. Not sure if 4mos list the spacesaver

You sure its only 1"? In vic we can go 2" bigger diameter then standard, and 25mm wider (1")

[RubAVeeDubDub]

Just remember the law is regarding "rolling diameter" - I.e the diameter of the wheel AND tyre together. You are allowed to adjust the tyre size and wheel size as long as the rolling diameter of them together are not 15mm greater than the biggest wheel&tyre combo fitted to that model of car or 15mm smaller than the smallest combo fitted to the car.
Wheel width wise you're only allowed to go 1" wider than the widdest factory wheel fitted to the model of car. For the Bora the widdest is 7.5" so you can legally git 8.5" wheels.
