As far as the math and clearances go I would have to refer you to an expert like @Brian@BMVK to answer this question. My driving was on the street and I did a bunch of tests with no contact or rubbing.
I'm hoping @NightmareMoon will chime in as well. 10.5" wide seems to be the optimal width for a 295/35-19 tire.
I ran stock GT350 wheels for about a year before trading them for the stock PP2 wheels, and used the same 295/35-19 front and 305/35-19 rear tires on both sets of wheels. No issues whatsoever with the GT350 wheels. Getting a little rubbing in the front with the PP2 wheels when I bottom out the suspension, but I also lowered the car a little so I'm sure that's part of the problem (soon to be rectified). The GT350 wheels were paired with the stock PP1 suspension.
I think a 5mm spacer would be enough to solve your issue. It would change your offset from +35 to +30.
Speaking of... where do you buy GT350 wheels? I don't know the part number and I cannot find a source for them anywhere. Only wheels that come in those sizes seem to be custom wheels which I have no doubt are lighter. 10.5 wheels for Mustangs seems to be a rare breed.
As mentioned above, a 10.5" ET 24 is a stock PP2 fitment and those run 305s. I concur its a 6.7" backspace. Its pretty generous on the inside clearance, assuming you're not doing anything funny like running camber bolts.
Well the decision has been made. I purchased these wheels instead of the SVE.
I went for the 9.5/10 wheel setup and I'll continue to use my factory PP1 tires. Maybe I'll go a little wider in the rear next time I need new tires but not by much maybe like 285s.
I purchased the wheel kit M1007KDC19MB
instead of purchasing each wheel individually, comes with the pressure sensors.
I ended up paying much more than what the sve kit cost but I like the idea of having a factor spec setup I'll even be able to use my existing lug nuts and locks, probably even the same center cap since the Ford performance caps I believe are the same size as the PP1 caps.
Not having to worry about rubbing, offsets, spacers, or studs was the deciding factor for me. I know getting new wheels and keeping all the same sizes is not sexy but that's okay for me
He mentioned that he wants to use a set of all seasons that he already has, I'd assume for winter use.
The post states that they have pp2 wheels with 275 all season tires installed and the end goal is to install 305 tires on the stock wheels after moving the 275 tires to a winter set of wheels. If they know the 275s fit on stock pp2 wheels, why not stick with the pp2 sizing? I'm only curious because I see a benefit in having the same size pp2 wheels in the long term.
That makes sense since the pp2 wheels poke. However, you may get used to running the 9.5/10 setup and then when summer comes, you may get too close to the curb with your pp2 wheels. I have 285/35 on my 19x10 SVE wheels and there's very little protection for the rim. I'd imagine 275 wouldn't really help the 10" but maybe the 9.5". Unless of course you have tires designed to help protect the rim. Also, you mentioned the SVE wheels. If you hold off, you may be able to get the SVE wheels before winter. There's so many variables, but it might be worth waiting to get the wheels and wheel size you want.
Yeah, I guess I may hold off and do that. You have no protection?! Try running 275's on 10.5/11 inch wheels lol. I park about a foot away from the curb because of that. I will post pictures later.
Hi Gismo, is this 10 inch square setup? Should I go for this setup with the replicas to use my 275's? I guess the Ford wheels and the SVE wheels have different offsets, but wanted to hear of your opinion.
