Anyone running a true square (width+offset) setup?

[Sprintamx]

You sound like pass though type spacers don't fail either. Anytime when you use longer studs and more moving surfaces, you are allowing the studs to rotate and bend. Studs are not designed to withstand this kind of force that is why wheels need to be mounted as close to the base of the suds as possible.
You go believe what you believe in but don't call other people idiots because of your ignorance.
Also good luck finding a 25mm shim.

I didn't call you an idiot, but I did call you ignorant, and you still haven't shown that's wrong. This is exactly the kind of garbage that I was hoping to avoid, as I explained in my OP. But you just had to jump in. And now, we apparently can't get a 25mm adapter either. Strange considering all the options that are available.

I think I'm done with this.

Like these? A member here is running them fine with a few track days under the belt on this GT350 with a 19x11+50 square setup

Id personally got 19x11+50...that will give you the same stance as the stock R 19x11.5+62. Then +50 with a 25mm spacer will match the R front offset

19x11 +55 will give same as a stock R. Don't forget that the offset distance is purely observed in the outward direction, but when you factor in the 0.5" (12.6mm) extra width of the rim, half of that extends on the inside of the wheel and half extends the wheel in the outward direction.

Which is why a 19x11 +55 is used as it is the closest option to get same offset as a stock R

That is true, I'm saying from a fender fitment/flushness view, +50 matches the R and is known to work, so might as well use it and give yourself more suspension clearance

The question then is what spacer to run on the front to keep the wheel tucked in. The trick for us non-engineers to understand that the offset numbers and fitment run in reverse.

No no, from a fitment point of view, an 11" wide wheel at +55 sits in the exact same position as an 11.5" at +62. If you put an 11" at +50, then it is actually 5-6mm further outwards than the stock R setup.

I just picked up a set Forgestar CF5v in 19x11. I went with different front and rear offsets though, as my tire shop will swap tires from wheel to wheel at no charge. Front offset is 24 and rear is 56. Fronts weigh 24.9 and rears weigh 23.4. I took the Forgestar route for the same reasons you stated in your original post and have had good luck with them in the past....very reasonable strength and weight for the price. I have not had them out on track yet though.

Another flow formed wheel option is the HRE FF15. They're more expensive than the Forgestars and I'm not a big fan of their look. Someone here posted a thread with them on his R at the track. A search should locate that for you. There is also good info on another thread from someone running a squared setup with spacers. I'm sure you will find it with a google search. Good luck.

I'm not sure of the offset on the front wheels, I thought it was +33 or thereabouts??

Easy way to think about it, is that the lower the "offset" the smaller the distance between the wheel hub face and the centerline of the wheel itself. The smaller the number, the more concave a wheel will become, and vice versa. I personally wouldn't run the spacer just because I'm paranoid and because it could create a "cantilever" type loading on the studs.

If you're intent on doing it, around a +25 or so should work to create a nice square setup, and you shouldn't have any issues with brake clearances with the higher offsets in the front either. Just got to determine the exact offset in the front and you're pretty well set.

The CF5V is one of the wheels I've been looking at. Running the staggered setup is definitely a prime option, and simpler in many ways.

Thanks for the input.

Agree....I'm fortunate to have a great relationship with my tire shop. Although not ideal, running a non-directional tire and rotating side to side is also a reasonably good approach for me with the tracks I run.

1/2" = 12.7mm

Sorry not trying to be a dick...:cheers:

 

[cjgt350]

Stock GT350 offsets are +30/62mm R's are +24/56mm. Both are listed F/R

A 25mm spacer seems to be necessary for a true square setup here. I admit that's a relatively thick spacer.

What tires are you running? I'm going to mount a set of PS2s to start.
