Will 19x8,5" ET35 fit on a facelift mk2?

[scootie]

As topic says, would ET35-wheels fit or is ET45 a must? 

[chimaera]

The ET value is the distance from the centre of the tyre's contact patch (and therefore the centre of the wheel) and the mounting flange where it mounts onto the hub. That offset is important for the suspension and steering geometry to function correctly. If you change the offset then you will affect steering behaviour in particular as it will mess with the caster behaviour.

 

This thread has the offsets of the stock 17" & 18" wheels listed: http://www.briskoda.net/forums/topic/112862-superbs-oem-wheels-et-number/

 

You'll see they're all around 46-49 mm. Changing to ET35 on the same section size would mean the inside edge of the wheel/tyre moves 11 mm closer to the suspension if the original wheel was ET46. Reducing the offset this way will make the car a little harder to control in a straight line, especially on bumpy roads due to a reduction in the self-centering effect.

 

If you get the 19x8.5 ET35 wheels, the inside of the wheel will be about 24 mm closer to the suspension than the stock wheel (assuming it's 18x7.5 or 17x7.5). This is the change in offset (11 mm) plus half the additional width of the wheel (12.7 mm/0.5"). I've no idea what the clearances are in there though so I can't say if it'll fit or not.

What about spacers?

What about them? Adding spacers lowers your ET making the wheels poke out more.

[chimaera]

There's a bunch of weirdness in terminology which can end up being quite confusing here to the extent I got it backwards in my earlier post. (I blame several hours of reading through PLC code!)

 

The hub flange is the fixed point: reducing the ET value moves the centre of the wheel towards the hub flange, i.e. towards the outside of the car; increasing the ET value moves the centre of the wheel away from the hub flange, i.e. towards the suspension.

 

 

You'll see they're all around 46-49 mm. Changing to ET35 on the same section size would mean the inside edge of the wheel/tyre moves 11 mm closer to the suspension if the original wheel was ET46. Reducing the offset this way will make the car a little harder to control in a straight line, especially on bumpy roads due to a reduction in the self-centering effect.

 

This should have read:

 

You'll see they're all around 46-49 mm. Changing to ET35 on the same section size would mean the inside edge of the wheel/tyre moves 11 mm to the bodywork if the original wheel was ET46. Reducing the offset this way will make the steering heavier since the caster effect is increased.

 

Adding a spacer effectively reduces the ET value, so it can be useful when fitting a wheel with a /larger/ ET value than the one it replaces. It'll compound the problems of fitting a wheel with a smaller ET.

ET35 fits, but it might poke out a bit in the front, especially with 8,5" rims. I have ET40 and 8", and they are pretty spot on. I might add 5mm spacers to the rear.

kewl, got any pics?

[Llinded]

Here's a few.

 

I'm going to lower it more with H&R springs. The -30mm Eibachs are not enough IMO.

Ah, is it lowered on 30mm springs all around? Maybe coils would be the way to go? Could you maybe do a sideshot of the rims so we can see how it aligns with the body of the car. From the included pics it looks like ET35 actually is a pretty good fit and would open up for more rim alternatives since the market is pretty limited with ET45 rims :(

It's the Bilstein B12 kit. Bilstein B8 shocks and Eibach springs. Coilovers would be great, but I just bought these Bilsteins. I can take some shots from the fender clearance later today.

Thanks for the pics! That looks perfect! And with proper stretch a little more lowering shouldn't be a issue even on ET35! This makes me more confident on ordering a set of rims

Sorry for bringing back an old thread. Just wondering what size tires your running on those wheels w the 40 ET. 

 

I just bought a 2012 1.8 and have a set of 18x8 ET42 Audi wheels w 245-40-18s. Trying to estimate it out if they will fit. Rims are no issue. But I can see the tires are a bit wide for most on this site. 

Thanks

Joe

[Greenline3Matt]

The wheels would fit fine but you would need to change the tyres to 225/40's otherwise they will foul.

[Joelliott]

Damn. Ok. I liked the look of the 245s on these wheels. But I guess it's a no go. Must be kind of small wheel arches on such a large car? 

 

Appreciate the help too 

[Wile7]

Mine has summer 19s with the tyres GreenlineMatt says. Lowered 40mm. Runs fine BUT will ground out occasionally with full load and four folks on board...bizarrely on the inside of the rear tyres, not the outer.

 

I've posted quite a bit about this....do a search to find more.

I searched your posts, though on mobile and nothing came up with car grounding

 

Anyway, I want to buy 19x8.5 et35, they will most likely look flush, but I'm wondering how it will perform in a turn on a huge bump for example. I'm considering rolling the front fenders just in case. My car is lowered 30 mm with eibach pro kit.

What's your wheel spec?

[metlovas]

Hey, Well I'm running 19" 8.5 ET40 and they sit perfectly on mine so yours should be slightly more inside

[metlovas]

Just not lowered yet

Yes yes I know,  just don't have money for decent coils, but do have set of lowering springs 40mm sitting in a shed. Not too sure if they are not going to ruin the rest of the suspension components 

[Joelliott]

I actually kind of disagree. I like the higher stance. I know it's factory etc. But it looks good on those wheels. I'd maybe even try to squeeze a 40 series tire on those 19s just to fill out the gap. 

 

No rubbing w that combo you have?

Nop no rubbing at all, front tyres are 235x35 and the tears are 245x35. But I think next time I'll put 245 at front as well, I only just about to touch inside of the tyre on really full lock,  but just about, so should be fine 245 as I prefer more rubber 

And I don't know if I want 40 tyres either

Well I've been doing to research and taking some measurements on my perB. The used 18x8 et 42 w 245/40s works fine. No running etc. I tried everything... Speed bumps, reverse up over bumps at full steering lock. Only time I heard a scrape was while hitting a speed bump at 50 km/h w 3 people in the car. So I'm thinking it's good. 

 

Brings me to this. 

 

I looking at some Calibre wheels that are 19x8 or 9. I'm thinking of running a combo of 19x8 et 40 in the front w a 235/35/19. Then a 19x9 et 35 in the rear w a 245/35/19. 

 

Question is, will the minute difference in tire height set off the tire pressure alarm?
