Not sure if my tire set-up works
I had to purchase new tires today and I'm not sure but I think the guy from Big O Tires might have gotten the wrong tires for me. If you guys can help me out I'd greatly appreciate it. I have the GT rims 18/19 combo and the guy ordered 285/35/19 for the rears and 225/45/18 for the fronts. The front rims are 18X9 will the 225/45/18 fit or even work with the fronts. I know the rears fit fine but I'm not too sure about the fronts.

225 front and 285 rear will make the car understeer.

but I looked again and the stocks are 245/40/18's. I think he just messed up. But that's what I get for not paying attention.

^^ He probably looked at the chart for 18x8” wheels (the common wheel size for Z’s) which are usually fitted with 225/45-18” front tires.
225 on your 9” wide wheels will be stretched. A bigger problem is teaming 225 fronts with 285 rears. The 285 rears will overpower the 225 fronts in turns. This combination would create a great deal of understeer (poor handling) and cause your fronts to wear quickly.

It’s certainly not an exchange. As you point out, you don’t have the tires yet. Add to this the dealer is liable here for offering/suggesting a poor setup. 225’s on 9” wheels will be stretched, and combining 225’s with 285’s will make the car understeer to the point it will “plow” in tight turns. A 245/40-18” or 255/40-18” tire in front will work well.

Will that make your TCS complain?

sorry to thread jack but dont want to start another.
Currently running 19x9.5 +17 front and 19x10.5 +18 Rear. 255/35/19 upfront and 275/35/19 rear. I think I would like to go with 285/35/19 in the rear. I understand this might cause rubbing but am willing to roll the fender if necessary.
My question is this is the size i should go with correct? 285/35/19
not 285/30/19. (saw a pic of the same wheel running 285/30/19 so got a little confused)

Each tire can fit on a range of rim sizes. My DD tires are 225f and 235r. My track tires are 275 all around. (17x7.5f 17x8r)

^^ I’ve lost track (excuse the pun) of what you’re doing. This is really getting “screwed-up.” 
If I have it right, you are now planning 245/40-18” on 18x9” wheels front, and 295/35-19” rear (changed from the original plan of installing 285/35-19” rear because the tire dealer doesn’t have 285/35-19”
).
If that is the case, it works for matching OEM tire size specifications as to overall diameter (tire height). It will work with VDC or TCS.
But, I wonder about this new suggestion your tire guy is making (295’s on the rear instead of 285’s that you originally ordered). 275/35-19” will fit and work perfectly, and that’s probably the case with 285/35-19” tires. I’m not sure about 295/35-19” tires. This size may rub during full suspension travel with your rear wheels.
I would print-out this thread and show it to your tire guy. I think 295’s on the rear will overpower 245’s on the front and push your car into an understeer situation when you turn-in hard during cornering.
Actually, you should ask for a full refund and go to another tire shop that knows what they are doing and stocks a full line of tires.

I did just that... My buddy called me right before heading to the tire shop when I asked him to find me some 285/35/19 tires. He found them with in 2 minutes of searching. I went to Big O Tires and requested a refund. The manager came out telling me that they can't refund money on special ordered items. Finally I had it and demanded my money back. Went down to my buddy's shop where he had my Falkens 452's waiting for me. I got the 245/40/18 front and 285/35/19 for the rear.
I was desperate since I had two nails in both my rears that were on run flats and no tire shop would touch nor patch them. I figured Big O Tires could handle getting me tires asap but they just caused nothing but headaches.
