    I have the Ford FR3 track suspension with camber plates getting -2.5 camber. I am currently running 10"/11" with 295/305 tires, these tires run really wide, the 295 is as wide as a 305 Nitto 555G2, and I have no interference problem. The R350 11" has a better offset profile I believe than the S350 does if you want to run them up front. I'm looking to go square 305/11 next year, just in the process of getting stuff in to see what kind of joy that's going to entail.

    One of the S550 cars I help out with down here, has the 305/30-19 cup2 tires (they really run wide!) on the 19x11 SVE 350S wheels running square... needed a 20mm spacer up front. but fits fine.

    Our new 19" SM-10 wheels are available in an 11" square, but non-rotatable, set up by running the 19x11" ET26 up front and 19x11" ET52 in the rear. Or you could go the square and rotatable route with 19x11" ET52 all around and run a spacer up front, generally in the 25mm range.

    This car runs the 52 offset all around with a 20mm spacer up front (offset struts allow for a bit more room)

    And this car is running 19x11" ET26 up front.

    Furthermore, I would encourage you to look at 305/30-19 tires instead of the 305/35-19 as there are FAR more options available in the 30 series sidewall. Lastly, a 295 or 305 wide tire is better supported on an 11" wheel compared to a 10.5".

    Picking up a Apex 18x11 compared to a SVE 19x11 you really see how much stronger the Apex wheels are..... I would hesitate to go full out crazy on the track with the 19" SVE 350 wheels.... looks more like a street or auto cross wheel at best. The SVE drifts are more robust.

    Full disclosure!! I have 6 Apex wheels and three more coming soon!! Lol! I turns out that the one that lost a slick was repairable..... but will leave it as a spare of last resort

    All depends on what you're doing, for lapping days I have no problem with using the SVE wheels. If I was going racing again I'd be looking for better, but for what I do they are very cost effective and are working fine for me. As race wheels? Nope.

    Haha nothing gets people going like taxes! Thank you all for the Monday morning laugh.

    Do you have an S197 or S550? Are the Ford FR3 track struts much narrower than stock? I really like the idea of being able to fit an 11" wheel...

    I'm assuming if he's running Cup 2's that he is running on track and not just getting wide wheels for "stance". No rubbing at all on track with those wheels & tires??

    Thanks Cory! Does running a shallow offset rub in the back (like 19x11" ET26)? It looks like I might have to run spacers then if I want something wider than 10" and still be able to rotate. Do those wheels extend beyond the fenders or site flush/just inside? If they go beyond the fenders, I might get bumped up a class and I'd also be worried about rubbing because I'm on stock suspension. I have really been wanting to try Apex wheels but just can't afford the cost to bring them here to Canada in those sizes... I'll send you a PM.

    You would need to run 19x11" ET52 in the rear, the ET26 will not fit (big poke out back). The ET26 up front or ET52 with a spacer will be pretty flush with the fenders.

    This car has 18x11" ET52 up front with a 20mm spacer and 315/30-18 BFG Rival tires. When combined with -3* camber, you can see that it does not rub with the front suspension under compression. Close, yes. But just enough space.

    S550, 2016 base with PP1 and Recaros and nothing else. The FR3 struts look just like the stock ones, I didn't measure them though. I'm hoping a 22mm spacer will do the job perhaps with some bolt hole grinding.

    That's great to know, thanks. I'll add spacers to the shopping list, then.

    Sounds good, please post how it turns out!

    Good to know, thanks! After wheels and tires, springs and dampers are next on the list.

    So I had a chance today to test 305/30/19 on 11" rims (+50 offset) on the front, with a 20mm spacer I have at least 4mm to the first point of interference which is a ridge of rubber on the sidewall right above the top edge of the rim and that protrudes 3mm beyond the wheel. So I think I am OK, but would be happier if that ridge of rubber wasn't there.

    That sounds promising, thanks! I'm sorry if you mentioned already, but what tires are you running?

    Anything "right above the top edge of the rim" isn't going to move anywhere near 4mm. Unless you've got a much bigger problem, like the tire going flat, or the wheel center bending at least that much all the way around.

    I've run 18x11 Forgestars with less than 2mm tire and wheel to strut clearance and not had rubbing with Aim solo readings up past 1.2g laterally.
