GR86 GR86 - What wheels and tyres are you thinking about?

I thought 16s might go over the brakes. I have a set, but I think the offset is going to be too low---if the GR is around 47 or so, these are 35 so might stick out too much. Perhaps a cheap set of GT86 Primo wheels is the way to go.

I see it as an opportunity to loose some unsprung weight and increase comfort a little , try to make the discs not look lost under 18s along with them not being black 👍😎

You can change the clutch spring for a weaker one or remove it all together.

16's do fit over the brakes, some of the guys in the US have fitted them. That offset isn't a problem as the chances are they will be a narrower 7 inch wheel anyway. You might struggle to find primo wheels as they only sold a handful of them in the UK.

If it's the same issue as it's predecessor, then yes....

There's a spring on the clutch pedal, which serves two purposes - as you push the pedal down, it provides some assistance to make the clutch feel lighter.
It's on a pivot, so that as you release the pedal, after a certain point it switches from pushing the pedal down, to pushing it up - thus, it keeps the pedal fully in the up position when your foot is off it.

However, the spring is quite heavy (it has to be to provide any meaningful assistance when depressing the clutch). So as you are bringing your foot up, when you get to the point where the spring switches it's fulcrum, it suddenly puts upward pressure on the pedal, which feels unnatural and gives that sudden 'snatchy', binary feeling.

Solution is quite simple - replace the spring for a weaker one. It makes the clutch feel heavier and more 'sports car like', and reduces that odd, binary-feeling on pedal release.

EDIT: beaten by ZN8.
 
Thanks to @ZN8 and @Conscript for the clear and concise explanation of why the clutch pedal has a ”binary on/off” feel. I’ve seen it mentioned several times already by folk who Have had test drives. As I’m sure this will be a topic of discussion I’ve created a thread here:

GR86 - GR86 - The clutch pedal thread

The place to post all things related to the GR86 clutch pedal , questions, answers, modifications etc
www.gr-zoo.com www.gr-zoo.com

If @ZN8 or @Conscript, or anyone else , would like to post the answer to the question “Why does the clutch pedal feel binary - on/off ?“ I’m sure a lot of folk will find it useful 👍
 
It somewhat spoilt my enjoyment of driving it, so if this is a quick, simple, and cheap fix then I'm sure that nsny similar grumblers will pounce on this solution. Thanks @All 👍
 
I know they’re a bit on the cheap side but I like the look of Japan Racing SL01. 18x8.5 ET 40-44 with 235 tyres looks pretty good to my eyes.

Not exactly those wheels but similar:

@mackie The SL01 is closer to TItan 7 TS-5, the wheels in the photo are Konig Ampliform.

The Ampliform is a mesh inspired, flow formed wheel design. The Ampliform is offered in 17x8", 17x9", 18x8.5", 18x9.5", 18x10", 19x8.5", 19x9.5", 19x10", 19x10.5", 20x8.5", 20x9.5", 20x11" and finished in Gloss Bronze or Dark Metallic Graphite.

Yep, those are them. I think that fitment looks really good with stock ride height and normal camber.

Is that car in the photo at stock height mackie? I often find aftermarket wheels which are wider and have a lower offset exaggerates the ride height.

I’ll find the forum thread but I think he said it was stock height, it certainly doesn’t look lowered to me as the wheel is still centred in the arch and bare in mind that the tyre diameter is slightly larger than stock being a 235/40.

On page 2 he says he’s got camber plates but otherwise OEM.

There are two fitments which we offer, more road and track biased respectively.

18X8.5 +45 and 18X9.5 +40.

There is a special fitment of 17x7.5 +44 offered in Japan for the GT86/BRZ cup, I have been told it's a 5Zigen exclusive, but truth be told I've not made much of an effort to try and get my hands on any so far.

If there was enough interest on the board, a group buy could be done to improve things more than the standard GR-zoo discount I would offer.

Looking forward to seeing them on the car. What offset are they?

I got them off eBay supposedly from a scrapped GT86, guy didn’t know offset but I’ve measured it to be about 44mm so hopefully should be spot on.

They look really different depending on the light, here’s a group shot.

They are at the detailing shop now waiting for some ceramic coating ready for the car whenever that comes…
 
I have made my decision and ordered the 18x8 +45 Tomason TN25 superlight in matt bronze yesterday. They are currently discounted (23%) and cost only 199 € (171 £). With only 7,91 kg (17,4 lb) they are also indeed super light 🪶

Nice looking wheel And That’s a great price @Shoggy and presumably have TUV certificate so we know they are sound 👍 Are they flow formed or forged🤔

As far as I know they are flow formed. They have no certificate yet but luckily we have a big motor show going on in Germany right now. One guy from our WhatsApp group asked at their booth if they will offer something for the GR86 and they confirmed the TN25 will receive a certificate at the end of February next year. I gave them a call yesterday to have it confirmed again and then placed my order to secure the discounted price.
I will put them on in summer. For winter I will use the original wheels with winter tyres.
