17" wheel thread

there's sparse information in various places, so I figured maybe those of us interested in going with a smaller diameter wheel, maybe we consolidate what we know?

fitment of a 17" wheel is going to depend on the barrel of the wheel clearing the caliper, but also the spokes clearing the caliper, in addition to the normal clearance issues that might happen with suspension bits, or body parts.

so maybe, as we confirm 17" wheels that fit, or don't fit it can be posted here, along with the standard specs? wheel size, including offset, and then also tire info, if applicable.

there's this thread on the GRYaris forum that has:

braid fullrace A: 17x8 +27
TE37 17x8.5 +40

they also recommend stone scrapers on the calipers so as not to damage wheel barrels when a stone gets stuck between the caliper and barrel. that same thread says RPF1 and Rays CE28n both at 17x8 do not fit, but don't mention any offset

Hey everyone! I know we were a little more active in this thread in the beginning and it looks like we disappeared a bit, but I swear that we've been active. Lurking, but actively so.

That said, we did want to share that we have our 17x8.5" ET23 SM-10RS Forged Wheels in stock and ready to go! While these were originally designed for SCCA Street Class, they're still a great option for those who want a direct-fit 17" wheel option that clears stock brakes.

60° Shank Lug Nuts are required. We're still working on an in-house lug nut solution, but in the meantime we have had success with these particular lug nuts and are recommending them until then: 60° Shank / Extended Thread Lug Nuts

That's all for now!

I don’t like red calipers, so installed a set of the oem black calipers (which are stock on the core cars without the performance package, and identical except for the color).

Mounted the 17x7 Braid wheels with snow tires for rallycross. Also installed Rally Armor mudflaps— actually mounted those on top of the Megachip ones. My thought is to install the Rally Armor ones when I rallycross, but remove them for normal driving.

Digging around the forums and maybe I missed it, but do you have the Eibach lift springs on your car or is this a fitment with 17" Braids on stock suspension? I'm waiting to hear back from Braid to see if any of their other wheels will fit like this one. I'd like to get the Dakar Classics or Winrace N Lars if possible.

Car looks good, digging the orange!

I just finished installing a set of 17x9 +25 Konig Hypergrams on my GRC. Currently wrapped in Conti ExtremeContact Sport 02 in a 275/40R17. The wheel mounts fine and the provided lug nuts from Tire Rack got about 9-10 turns out of them. Otherwise zero rubbing and it all fits perfectly. Yes, I'm aware that I am ultimately giving up steering response over say a 245/255 tire. But for a street car I like having more protection and truthful the 02s provide a comparable immediate response to the 235/40R18 PS4 tires.

Since the image broke, here's a gallery of the fitment.

I appreciate the info. I'll have to dust off my IG account to contact him. Do you have all the parts lined up? Any concerns about fitment and alignment post-install?
The parts list never ends. I have given myself a strict budget to slow the modding down. Between my 2 cars, I've spent prob close to $10k in mods I didn't expect. Not running my bill up on affirm or credit cards lol.

Message slottoauto as he's the one literally running 15's on his GRC as seen on his account

There's been a few options out for a while iirc, but I haven't seen anyone on here use them.
yes and no, this option is affordable. I rather not disclose his great product. I can assure you this is more affordable and if not better.

Disclose that he's using the RC brake kit? 😅

Slottauto is a scumbag. He tired to scalp a GR back in early 2023.

I msg him in Feb of this year for his "kit" and he quoted me $1700 I already knew of the RC kit. But the kit in Japan includes e210 knuckles, which his did not. Until he finally posted images of his kit and they were rc parts, not developed by him, developed by Toyota. Yes he was the first to take the time and see what parts fit. But this guy is a crook. I hope no one gives him any more of their hard earned money.

@BossHyperion
-5x114.3 ✅
-56.1mm center bore ❌ ours is 60.1mm
-Brake clearance likely good since it clears brembos
-offset is 53mm which much higher than our stock 30mm which is also on a 1/2” wider wheel. So these will be much more narrow and would benefit from spacers.

Otherwise it’s a great wheel! I have a pair of wheels designed for a Subaru that I plan to try using a low grit cylinder hone on to get the additional 4mm center bore (2mm of material to be removed).

Thanks for detailed response, might see if I can find some spacers to make these fit, will post back here with results.

FYI: I have a set of 17x8 +53 2011-2014 wrx wheels that I used for my crosstrek when I tracked it. But needed to get adapters when I used them on the is300 due to different PCD 5x100 and CB 56.1. they're enkei cast and do not fit the fronts with a 25mm adapter due to the barrel. It won't go past the dust shield.

The Fast Tactic 17" mags came off last weekend after their first Quebec winter (~6000km driven), and as predicted in this thread, the tight clearance with the caliper means that small rocks and debris can wedge themselves between the caliper and the mag, scraping both.

The white arrows indicate the scrapes (which don't yet go all the way around the inside of the mag), and the non-darkened circles indicate the contact point on the calipers.

The white arrows by the weights indicate just how far outboard they need to be installed so as not to interfere. Notice the adhesive just inboard from the weights: that's where the shop installed them on their first pass, which didn't clear.

Overall, the Fast Tactic 17" mags have been great for the winter (see my post earlier in this thread) despite the occasional contact. For those considering them, be aware that they'll leave their mark even with normal street use.

Haven't confirmed, but as a unrepentant race car builder I always try and optimize performance. Best bang for the buck to me is going to be the RFP1 in 17x9 ET 22 with 255/40 which will give 28.8mm wider track width and 40mm more lateral rubber while reducing wheel weight, increasing impact resistance, and being ever so slightly smaller total diameter (1.48%) which will improve acceleration/ gearing and the unsprung weight reduction will improve grip and suspension performance. I'd do it in a heartbeat, but this is a company car. Still tempted to do anyway. I've only had it a couple days and already scheming wheels, tires, rear swaybar and springs at least lol.
