Well, with an offset of +30mm on your new front wheels, they will poke out 16.4mm more than your stock GS wheels (that's why they are rubbing on the outside of the front tires)
Had you purchased these same new wheels with an offset of +40mm, they would only poke out 6.6mm more than the stock GS front wheels.
Below is the numbers concerning the new front wheels you have on it now ...
Thanks that explains it but will raising the ride height help stop the rubbing or do I need to buy new wheels? I may grind down the plastic fender liner to relieve the rubbing.
Thanks.

Do these tires stick outside of fender. The combination of putting the rim 5/8+ (17 mm poke difference) inch out (with not really going in) and the wider tire is probably to much for the car. I think most guys with 10s in the front have the offset more towards stock which I think is around 40 mm they just add 1/4 inch on each side while staying close to the 40 mm offset. The rear the offset is like 54 mm so your 50 mm is pretty close so those as you said fit fine and are also the stock size of 12 wide.
Factory stock Cup and ZR1 wheels are 19x10 and have a +40mm offset. With 285/30 -19 tires there is no rubbing on Z06s, ZR1s, 427 convertibles, or GSs. Looks like the problem is the +30 offset on your front wheels.
I thought this old man did his homework. Wish I understood the offset before I bought these wheels. Now I'm stuck with these wheels.
Maybe raising the car a little will help, but NOT like the yellow Corvette pictures in this thread. LOL

This same Varro VDO1 wheel is available with a 40 offset. I would like to purchase them if I knew for sure they wouldn't rub with the 285 tires up front.

Cup wheels and OEM ZR1 wheels with 285/30-19 tires were standard or optional on ZR1s, Z06s, 427 verts, and will fit just fine on Grand Sports which share the same wide body front fender dimensions even though the GS fenders are slightly different in the side vents behind the wheel wells. Of course, that's if the car is at stock or very slightly lowered ride height. If it's really slammed, all bets are off and you'll probably get some rubbing on bumps and/or full lock turns.
To check for yourself, see if you can borrow and test fit some front wheels off one of the above mentioned cars.
If the stock wheels work OK on your car, and IF (big if!) the aftermarket wheel seller accurately states their specs, you should be fine w/ 19x10 + 40mm wheels wherever they come from.
I talked to the manufacturer and they do NOT have that wheel in a 40 offset.
My guess is maybe the previous owner lowered the car.
My mechanic will take care of it.
Till then I'm driving my 2004 ZO6 Commemorative Edition.
Life is GOOD!!!
