Lets see those 18" wheel setups!

Thank you for the reply, I did go with the 275/35 just incase - 305/35 for the tires on 18x10+32 18x10.5 +35 in the rear. For a nice meaty flush look! Plus these Enkei gtc02 are super light !

I came very close to buying them as a second set for track days. Congrats post pics when you get them installed.

Does anyone know about fitment in Advan TC4’s? I was on fitment industry looking at some in 18” and their website says that there is a hub size issue, does anyone know about that? I’m looking at 18x9F 18x10R. Should they work because I see others have them ad well but don’t know if they’ve added or changed anything to get them to fit.

I have 18x10+32 square tc4's, 275/35 falken rt660s, 10mm front, 13mm(I think) rear ecs hubcentric spacers. I was on HKS springs before so idk if they contact the perch without spacers but probably. Only rub in the rear slightly on really big sharp bumps.

Yeah you rubbed a little be cause of the 13mm spacers it changed the offset to 22 which is close to the fender depending on your ride height

For more reference, this is what my 295/30/18 Conti Force tires look like on 18x10.5 GTC02.

Your mileage might very depending on the tire you are going to be using.

Depends how you look at it. Every thing that's changed affects other things. I don't rub on 275 michelins so the actual section width is also a factor.

I don't know if anyone noticed.. speed on speedometer is dependent on Overall Diameter of tire. Goal is to match the OD as close to OEM tires as much as possible and that is greatly effected by profile size (30, 35, 40, etc). It is also effected by construction of the tire as well. OD can be looked up by searching on internet for most of the tires.

Having said that, if you are using different tire than what car came with, speed on car's speedometer can offset and my previous cars stayed that way for obvious reason. On GR Supra, as you may know, I'm using 285/35-18 Pirelli P Zero tires which is smaller OD than OEM. Meaning, when my speedometer reads 65mph, it's actually 61 ish.. this was determined by driving on highway with Waze App turned on which showed the speed based on GPS. So far, all this was expected. However, what I didn't expect was, on return trip, speed on speedometer and Waze were very close at marginal 1~2% instead of 3~5% difference I had when tire was mounted first time.

So it looks like GR Supra has ability to adjust its speedometer based on telemetry it's reading. whether this is reflected on odometer is unknown though..

These are the Enkei gtc02 18x10 18x10.5 they came out great and can’t wait to start tracking it.

I had these tires as my track setup for my Camaro and they were crazy noisy. It almost sounded like I had straight cut gears. Are they any quieter on the Supra?
Aside from the roar, I absolutely loved the tires on the track.

R888 and R888R has whining noise on straight highway. On track, who cares about that noise..

One thing I know is that i3 speedometer always reads 3 mph fast. The odometer and clock are 100% accurate. The offset is on displayed speed only and if you look on can bus you can see true vehicle speed. VAG cars do this too, it is a german regulation thing.

I drove past a radar sign going indicated 35 mph in the supra and the sign said 32. If it can adjust itself I am going to go mad lol.

Not sure at what speed the offset ramps up. 0 is 0 obviously and I think at 40 kph it is indicating 45 kph (or mph equivalent), but I've not tested this. Apparently at 65 mph it is still reading +3 and not +6 (haven't tested this either but feels right)
