I want to run square 305/35/19x10" pilot super sport
 

Pilot super sport 305/35/19 on apex ec7 19x10 et25 square



I've been searching and haven't seen anyone attempting to run this exact setup. I've seen that you need to grind and run spacer for 19x10.5



I was hoping to run this set up without spacers, I do have the hub adapters. The reason I want to run this is I've been running 285/35/20x10 mpss that are 27.9" diameter and the 305/35/19 comes close at 27.4" diameter.


I had ordered 285/35/19 mpss that are actually RUN FLATS that weight 34 pounds and are 26.7" diameter, the 305's are 31 pounds.


Another option is 285/40/19 at 28" diameter


Many thanks

I run 305 30/19 on 19x11s all around. The front pokes about an inch with -1.5 camber up front. Front offset is +6, rear is +35. The rear pokes about .5". I pulled the fenders and plan on running -3.5, that should make it tuck in a bit better. I could have run a +8 or so and still maxed out the stock camber.


Reason I went +6 was some guys running oem ZL1 1LE wheels, which are +11, needed a 3mm spacer. It all worked out, the car is nice and grippy, now just begging for DSSV...



Wheels are Forgestar F14s. They are ok for the money.

I've got EC7 19x10.5 ET22 + 5mm spacer on the front of mine. At -2 deg camber, I'm just barely kissing the strut with the wheel (only enough to remove paint, haven't ground the strut yet) when running on the track due to deflection. Since you only have about 3 mm more clearance than me (-3 mm gap change from offset delta, +6 mm from narrower wheel), I'd guess you'll either need to grind the strut a little, use a 3-5 mm spacer, use less camber, or get camber plates to set the alignment instead of using the strut-knuckle joint.

I see that people are running 10.5+ wheels and have to run spacers and/or minor grinding...


I am wanting to know if anyone has experience with a 19x10 and 305's having clearance issues.


The more I research I might just go with 285/40/19. Apparently its a porsche spec'd tire that has tread width of 11.2!!! and 28" diameter

The issue with your proposed setup that in the original post that I'm trying to illustrate isn't the tire, it's the wheel. That's the reason some for using spacers or grinding the strut.

You're using a slightly different wheel than mine sure, but the math still works to show that you'll have risk of contact between the wheel and the strut depending on what you have for alignment and how you're driving the car. For instance, if you try to put an EC7 19x10 et25 on the front with no spacer or grinding, track alignment, and sustain any type of lat while driving, it's going to hit the strut.

If you know what alignment (specifically camber) specs you're going to use and what type of driving you're planning on doing I can give you a better idea if you'll be at risk of contact or not.

Pretty sure a 28" tire won't even go on the front, it will hit the strut on the OD.

I am currently in the same boat as this guy asking about the 19x10 except staggered. However, since Im a Noob when it comes to tire/wheel.. I'm interested in a setup like SeanBlurr photo shared above but I'm not willing to do any grinding whatsoever. Pretty much I want a Plug & Play setup. I can handle 19x10 ET 20 with 285/30/19 and 19x11 ET 43 305/30/19. I dont mind this setup. I will be using stock camber and the car will be used as a street and weekend track warrior once/twice a month. The question is will this work? Should I worry about the speedo error as well since I am getting 5% based "willtheyfit.com" on the uses of the car or Should I go with a taller tire like a 35?

I have a 19x10.5 +27 wheel on the front with a 6mm spacer (21 net offset) to clear the strut on a 1SS (non-MRC) with 305/30/19 tires. Based on the wheel offset calculator, with a 19x10 +25 wheel, you should have 2 mm more inner clearance than me so it should work.

Huh. I am going with a net 20mm offset on a 10.5” wheel. Maybe depends on the wheel too.
In my case it’s a apex ARC8 and preliminary mock up looks like I will most likely need to grind the shock slightly. 1SS. No MRC. Not a big deal. I will let you know when I do a full install. Waiting on custom built spacers now.

Wondering if anyone can add to the comments about the amount of poke for their setups. I have been very interested in a 19x10.5" square setup, but I do want to keep my tires flush with the fender as best as possible. Is this even possible with 10.5" rims? how about 10" rims?
