The quest for wider wheels and tires, 295, 305 and beyond...

@MasterC17 more camber?

Got the 305/30/19 Falken RT660's installed on the 10.5x19 ET25 MW03's! I believe they call this - snug.

Oh yeah! This should be the thumbnail for this thread.

@MasterC17 more camber?

Already running about -3 all around. Any more in the rear will likely have adverse affects.

 

[SK360]

Already done after I took the previous knuckle photo. Shaving a few mm off the knuckles is easy!

I heard you were being persuaded to do so . And here I was concerned about fitting a 275/35/19 660 on a 19x10 +35 lol.

Haha! FWIW these fit great with a 275 on them. I think even a 295 would work fine. But moving up from a 295 to a 305 adds .8" of tread width, which means the rear is just a bit too wide to make it fit.

What rims are you running? I have the same tires on 9.5 and don't like the result in auto-x.

What don't you like about the FT660's? What's your suspension and alignment?

19x10 et35 MRR M600…

What don’t you like about them? In 2 events so far in less than ideal conditions I’ve been 3rd in raw and FTD. Seem to be doing just fine

 

[MasterC17]

I spoke too soon. I used a Hunter laser alignment machine in a rush a few weeks back to get out to an AutoX event. As per usual, those machines are proving to be highly inaccurate. Manual measurements show my rear camber was only 2.2 degrees, not the 2.9 the lasers had shown.

So, I set them to the max-without-going-too-far of 3.2 and lo and behold - I think these puppies actually fit!

 

[gearchruncher]

I think that is the literal "splitting hairs" definition of fitting.

May your lap times be very low!

I don't see how that can move up.

 

[MasterC17]

I don't see how that can move up.

That's fully compressed (spring removed, sway bar off).

Basically if it moves up any further something is terribly wrong

ET35, these fit with the thinner performance rotor hats without spacers or rubbing?

With 265 RE’s yes. With 265 Falkens I needed a 5mm spacer. Next year I’m going to 275 and will probably need studs and an 8mm

The lengths you go for the science are impressive.

I don't like the 275s on a 9.5 rim. I think they are a bit less stable and wearing more in the shoulder. I think the 275 likely just needs wider rim then I am using, otherwise the tires seem like they should be great.

 

[gearchruncher]

I think they are a bit less stable and wearing more in the shoulder.

What camber and toe are you running?
I'm running 275 A052's on a 9.5 rim and getting very even wear at 2.3 degrees front, 2.0 rear.

 

[dsgerbc]

This is why I think somewhere between an ET30 and ET35 would be the perfect square setup for our cars.

So, it sounds like if one doesn't want to run 3 degrees or more of rear camber, these ETs are still a good target to shoot for?

Anyone aware of 19x10.5 wheels by reputable manufacturers in that offset range that don't take months to ship and don't cost an arm and a leg? The cost/benefit winner offerings from Konig don't seem to come in those offsets. I see some ESR/Savini offerings, of which I know next to nothing, and couldn't even find their weights.

Bumping the price range up:
I see some JDM Enkei RS05RR +32 on ebay....
And then there's a "Shelby" forged CS21 +30 wheel. It's ugly, but in-stock.

 

[gearchruncher]

@dsgerbc what is your goal with the car? Are you actually going to track it a lot? These really wide tires are a huge hit to range and other daily use.
