Polo 9N3 GTI Alloy Wheel Selection
Finally getting some OZ Superturismo GT wheels for my Polo 9N3 GTI. It has standard calipers etc, but will soon be running a Bilstein B12 kit which supposedly lowers it another ~1.5cm ... anyway ... Anyone happen to know which would be best suited between either:
7x17 / 5x100 / ET38
or
8x17 / 5x100 / ET35
Considering the original 'Denver' Mags are (supposedly?)6.5x16 ET38 ... will the 8x17 too wide and likely to rub, or is the different offset liable to have my brake caliper grind the **** out of the new inner wheel? There is barely 2mm of clearance between the caliper and stock alloy wheel as it is.

Re: Polo 9N3 GTI Alloy Wheel Selection
Really? If the offset is lower on the 8x17 (35 instead of 38) will that not alter the offset of the hub-face? Will it have *more* clearance between the brake caliper and spokes, or *less* clearance (potential collision with caliper) ? I really don't want to have to use spacers.

The simple answer is I had 8x17's et35's on my polo and they cleared by miles
The long answer is:
0 offset means the hub face is inline with the center of the wheel, Positive offset means its more towards the outside of the wheel, Negative more towards the inside
So the lower the offset the further outwards the wheel sits, The offset is lower on the wider wheel so that you have the same clearance to the shock strut/wheel well between the 2 wheels
Don't confuse this with the wheels spoke placement, Brake clearance depends on where the spokes are located within the wheel
worst case you your outside of the caliper sits flush with the hub face (wont be because the disk is offset inwards)
8" = 203mm (measured from the inside of the beading's)
Spoke thickness is 20mm in depth, But lets assume the back of the spokes on the OZ reps are straight and flush with the inside of the beading's
hub face is 35mm towards the outside of the wheel
so
101.5mm -35mm = 66.5mm that you will have between the spokes and the caliper, assuming the back of the spokes are inline with the beading of the wheel (as the supertourismo's are)
If you had a wheel with a lip you would subtract the depth of the lip and the spoke thickness as well
so 20mm lip and 20mm spoke
101.5mm -35mm -20mm - 20mm = 26.5mm clearance
hope that answers your question

That wheel size calc is useful, but as it states - "No warranties or guarantees are expressed or implied as to the accuracy of the information provided on this site."
Figured someone here must have first-hand knowledge of what works with a 9N3 GTI.
Also, when you say OZ reps, do you mean reproductions? I've found a set on ebay which are advertised as Produced by OZ (Zero mention of replica/reproduction) so I'd assume they are quality, genuine wheels?
I'm now wondering whether these will need 'hubcentric rings' too in order to fit a Polo's hub correctly? Cannot find any mention of what type of bolt I'm supposed to use either (tapered? radius?) ...
Anyone able to recommend good quality Superturismo GT-compatible black wheel bolts?
BTW if you search ebay for "Set of 4 Alloy Wheels OZ Racing SUPERTURISMO GT - 8x17 / 5x100 / ET35"... that is the set I'm looking at.
Thanks again for the very detailed information.

Re: Polo 9N3 GTI Alloy Wheel Selection
I'm currently running 17"/ 5x100 / ET35 / 8J Audi wheels and have no issues with rubbing on the fenders and the stock brake setup. I running a Koni sport shocks with HnR sport springs and the car sits pretty low with 205/40 profile tyres.

Sweet. Settled on OZ Ultraleggera, Matt Black, 17", 5x100, ET35, 8" Wide wheels from demontweeks. Currently in transit. Now for tires... Are 215/40/r17 too chunky for a 9N3 GTI running Bilstein B12 Sport kit (~1.5cm lower) ?

Hi, I'm good thanks...
A link for the Ultraleggera wheels? Just search on demontweeks for ultraleggera ... you'll need to select the stud pattern, size, offset etc from drop-down menus on the wheel's page. Best price I could find, and they included a fitting kit which should have the correct sized bolts and 'hubcentric rings' (TO BE CONFIRMED).
They've stated 28mm bolts on the invoice, whereas I've been reading elsewhere that 35/36mm "usable length" bolts are required ... Guess I'll find out when they arrive.
Nice Polo w/ sunroof... mine is Black too but 2-door.
Stay tuned

Cool thanks bud.
I actually went and checked them out, some decently priced rims there hey.
When your set arrives, kindly share customs costs etc.
Thanks again bud.
