Will 18" wheels fit with the ZTK package? I track this car and would like to know if anyone here has 18's. Tires are much cheaper and can get good track/street tires for 18's for a lot less than the 19's. I would like to have the same size tire ft. and rear so I can rotate them. Also, I don't want to spend a lot of money on wheels.

Yes. 18” Replika R231 fit over the ZTK brakes.

I did contact the supplier and yes they will fit but only the 18x8. I was hoping the 18x9 would work but they told me no.

Cause of the offset?
The 18x8 is ET25.

18x9 are a 35mm offset. I guess I will stick with 19s and pay the piper. Was hoping for 18 to buy less expensive tires but they are not that much cheaper. Tires are consumables when tracking.

Our 18x9 ET25s clear those ZTK brakes easily and have a Group Buy ongoing. ETA May on those so they might not work if you need something right away.

Where can we participate in this group buy? Also would 18x8.5 +24/25 clear?

The 18" Group Buy ended just over a month ago, but you can backorder a set of these wheels on our website: https://www.apexraceparts.com/shop-b..._diameter=%2C5

The width and offset alone won't tell you brake clearances. It'll be dependant on the design of the wheel spokes and barrel itself.
