If you use hub centric spacers you will be fine.

Its all come down to your comfort level....There are quite a few of us use spacers on the track because the wheel/tire configurations we have chosen dictate us to use spacers and we are comfortable with it and have not run into any issues. When a spacer is properly engineered, fabricated and installed, there is no gaps between the spacers and the wheels or spacers to the hubs, then all the forces that holding the wheels on the car are transferred to the lug nuts and the studs. That is why you should torque your lugs before you go on track (*COLD not after you come in from the session when everything is HOT!).
To answer your own question. If you dont use a spacer, will the new wheels you purchase work with the car? Are you happy to use the OEM setup or buy other wheels? Based on my personal research, I have yet to find a wheel that can fit both front and back without the need of a spacer for the front.
One more critical point. You should replace the OEM studs from the hubs with longer studs so that you are mounting the wheels to the hub through the spacers instead of the spacers that have bolts on them which mount the spacers to the hubs and wheels to the spacers instead. That would not be an ideal configuration for spacers setup.
I hope this helps.
Thank you for your detailed explanation! I haven't use any spacer in the past on track because my past vehicles run square setup from the factory and it is easy to find a set of rotatable wheels that have a square setup. That is why I want to make sure there are not any issues when using spacers on track. If I do not use spacers for my intended square setup, then I can change my wheel order to different offset. But the issue would be I have to dismount the tires whenever I need a rotation. Based on my past experience, I have to rotate tires before every track days. So if I do the setup without the spacers, then it is really a hassle for me in term of tire rotation.
That was one of the reason why setup with the square setup. I also learned something else. If your tires are NOT directional like the Michelin Super Sports (OEM) or the Cup 2 tires, you can rotate left and right after each track day/event if you like. By having the square setup, you can now rotate front to back as well as left and right. That should give all four of your tires a bit more even wear on each corner.
If done properly, meaning with race quality wheel studs like the ARP’s I posted a link to, there will be no issues. If you don’t want a rotatable setup then purchase specific offset wheels. With no disrespect to your friend wheels spacers have been used for decades. Many, 100’s?, of TMO members have used spacers with no issues. The photo below is a Ford Mustang factory race car using spacers.
Bolted connections with the use of studs and fitted spacers is used throughout industry. When properly clamped they become one. The spacers register on the hub flange and the wheel register on the spacer flange, the studs pass through the hub, spacer and wheel and when properly torqued become one unit. If this type of bolted connection was unreliable wheels and wheel hubs would be an integrated component. Crankshafts would be machined with integrated flywheels and vibration dampers, cylinder heads would be cast one piece with the engine block, sky scrapers would not use steel beams bolted to concrete. A proper fitting spacer and wheel stud is fairly reliable.
Thank you for ur explanation. This gives me peace of mind tracking the car.
Wow, I never knew that. I thought race teams do not use spacers. Poor knowledge...
So I know this setup will work on a regukar GT with the wheels sticking out about 1\4 inch. I have seen that a 10.5 with a 23mm offset will clear the stock gt front end. I am wondering what a 23mm offset on the rear will do though. The wheels i am looking at are only avaliable in that offset.
I don't think a 23mm offset is going to work on the rear. What wheels are you looking at?
I was looking at the konig amplitude wheels in a 19x10.5
Why not get something that's know to fit properly and has a better resale value?
Ive neen shopping around for a few different wheels. So far those are the pnly 10.5 i have found though. Everyone else is either 10 or 11
