The 19x11 with 325s was what Project GR6 recommended so I went with it. I am not hip to all the numbers myself to know any better, so the mfg recommendation was it for me.

Interesting thought though, I will keep aware of this. I don't expect these tires to last more than 2 1/2 summers so I'll try something else next time if I notice any funny business.
For sure man..

If you need some light bathroom reading sometime this is a good article.

Are you guys really noticing a difference with street driving from the lighter wheels? I go back and forth all the time on getting the SVE R350 (19x10, 19x11) wheels, which are about 24 pounds, or 9 pounds lighter than the stock PP1 wheels. Sounds nice until you figure in the extra weight of the tires. A stock 275/40 PS4S tire is 31 pounds while a 305/35 NT555 G2 tire, for example, to fit the 19x11 rear wheel is 35.3 pounds. The net weight savings with that setup would only be 4.7 pounds each for the rear wheels/tires. A pilot super sport in the same size is 31 pounds, same as stock, but then I would have to run a PS4S in the front at 285/35. Someone on here said they run this setup (PS4S in the front and PSS in the rear) and it's just fine but why can't Michelin make the PS4S in 305/35????

Maybe I am overthinking this :crackup:

I really like the stock PP1 wheels so I wouldn't want to spend the money unless there's a noticeable difference on the street, either from the reduced weight or the wider rubber.

I did notice a difference going from PP1s to 6GR7s, even with the added difference in tire weights. I'm used to it now, but when I first drove the car, it felt more nimble, accelerated more easily.

This is a great thread , good experiences shared . I’ve found that lighter wheels are aggravated less by bumps , not working the springs and shocks as much , therefore keeping the tire patch larger. Your ride is smoother. Then there’s the gyroscopic effect up through the steering wheel, making it feel like the whole vehicle feedback is a better at seat of the pants information. Acceleration is better and breaking is better let’s rolling mass.. Billy Johnson did a great article about this and also added the camber changes on alloy wheels vs stiffer Carbon fiber. Lighter is better, more than some realize.

+1 here

I can tell the difference between my signature wheels and carbon fiber all day, the signatures are great and light years better then factory alloys but the carbons are next level and no joke

That explains it! According to their site
  • Coupe Drop: Front - 1.5” Rear - 1.3”
The one thing I'm scratching my head over is it looks LOWER with the 19s (including less gap in your wheelwell) than it does with the 20s. I would expect the tire size/rim size to have some impact on height but not that much!
Yea I’m not sure, could be the sidewall. I’m running 30 sidewall on 19’s and the 20’s were 35 sidewall.

Just had my SVE M1 Reps installed! 19x10 +35 square set up and they looks amazing! 44 lbs lighter total weight savings than the OEM wheels and tires. I haven't ripped on them yet but I can already tell how much more nimble the steering and braking feels :)

Looks good! Hope you ceramic coated them before installation so they’re easier to clean 😉

They had a ceramic coat on them before they had tires on them lol!

Little update!
After stepping up to a 285/35 size tire up front my car now tram lines like a B****! The next mod I get will be a steeda G-Trac brace which should hopefully fix that issue! Just an fyi to those stepping up in size:like:

Which tires are you running? Some of it is the tire too. My Conti Extreme Contact Sport’s aren’t too bad except for grooved roads . The Steeda G Trac 2 point brace does help a bit

stop right there buddy. The Nitto you’ve listed is a terrible tire. Last thing you want to do is put on a poor quality “performance” tire just because its wider. You’re much better off with a 285 MP4S even if its stretched on a 11” wheel than running that Nitto G2 crap no matter if its a 345 wide tire. At least look for a MPSS for the rear.

But yes tire weight is a factor, so best thing is to compare wheel+tire weight not just wheel weight alone.

FWIW one of the best street tires out there, the Yokohama A052, is also one of the lightest (not not availible in the 19” sizes you’d like).

my fast wheel/tire setup (18x11/18x12” Apex VS5RS with 315/30R18 A052) weighs about 48 lbs total. The tires are about 28.4lbs each on my bathroom scale

Actually, try an alignment.

The car shoildn’t tramline badly with 285s unless you’re slightly toe out. Zero toe or slight toe in and it should drive fine.
