GR Yaris Wheel Weights & Data

[Kolbenkopp]

Hello friends,

apologies if this is redundant or otherwise out of place. If so, moderators please moderate .

That said, made a couple of notes while looking for some wheels. This is biased towards OEM fitment (8x18 in 8 or 8.5 wide), light weight and ability to get them past TÜV (German vehicle inspection) without too much hassle. I've tried to collect credible weights from folk that actually weighed a real wheel in the GR Yaris fitment.

Bit limited use for most, but it's just a start. Feel free to copy / add your own data and please correct mistakes that might have crept in.

Note: keep this thread to data please? Great thread with great pics already exists: https://www.gr-zoo.com/threads/show-us-your-aftermarket-wheels.9/

Great thread

Would be keen to see the Autec Clubracer Evo on a GRY, shame they don't seem to be available yet.

Wow da weds tc105x look good and seem to pretty light!

 

[Wubziz]

@Kolbenkopp Just weighted the DB8GT2 and those are 8,8kg, not 8,5kg.
Might be good to update this in the chart.

Way lighter than the (nearly same looking) JR03 (10,02kg at 18x8,5) but not the lightest of the bunch if you go only for "I need the lightest one!".
Looking really really good on the car tho.

I'd actually be interested in peoples experiences with the lighter weight wheels that aren't forged that are in this list.
Depending on the Design they might not hold up to the most "abuse" i.e. potholes etc. and could tend to crack quite easily.

Depending on the Design they might not hold up to

Design is a key word here.
Wheels are for many a 'car fashion' item with their 'design'.

Then there is structural design. There there is a slightly counter intuitive insight, that less material can be "stronger". Stronger as in less brittle, more likely to flex then to crack. The design as such can be just as important as the manufacturing method (cast, flow formed or forged).

Forged is obviously best but flow formed is a good bit on the way making for strong barrels. The best designs are lots of spokes that are quite thin and that do not go straight to the rim edge, or at least has a smooth transition to the edge. This distributes the forces most evenly and doesn't have 'hard' points along the rim edge (which usually gets the blow). But spokes that don't go to the rim edge don't look like the biggest wheel so this is slight opposition of what wheel fashion dictates. All according to my limited one person non-industry perspective.

Either way, the lightest wheels have quite a lot of design cues in common and that's not a coincidence....

You can add pro track one 17x9J ET45, weighs 8kg or so.
great thread btw!

ps. understand its slightly OT but then again not worth having multiple weight sheets on this site, maybe we could add all in one thread and each can see what they would like to use.

Yup I've noticed that too. However I've just recently seen an ATS Streetrallye (which isn't even the lightest wheel in the world tbh) hilariously fail after only two years of use on a car that weighs 1050KG. The wheel is TÜV approved as well as having one of those "typical" strong Designs. A medium sized pothole was enough to crack the wheel, with the tyre actually staying intact..

If you're concerned but don't want to pay top dollar for forged, go for flow formed. Note however that lot of wheels advertised as flow formed aren't actually flow formed until from a certain (usually quite large) size. The only ones in 18x8 I know for sure are the OZ with HLT in their name, and the Braid ones that are flow formed even in small sizes and are supposed to be very strong motorsport wheels (but I have no independent testing to proof that). Maybe others can add more.

PS: and weight doesn't say much about strength, can both work for and against strength all depending on where the weight sits and the material quality...

Thank you for the insights, thankfully I'm not currently on the hunt for new wheels, just wanted to add my input

Wedssport SA-25R 18x8.5 et 35 - 8.5kg

 

[Wubziz]

Borbet "Y" (color irrelevant) 8,0 x 18 - 10,3kg

I wanted to share my new setup.

OEM wheels 8 width and 225 tyres
Track setup 8.5 TC105X with 245 cup2 tyres and some light nuts.

Overall 500g lighter per wheel !

Still have to buy Wedssport aluminium hub-centric center cap (out of stock now) so it will add some weight back but those will not be heavy I guess
