Sucks, but sometimes you just have to realize that something might not have been a wise investment. I wouldn’t go more in debt trying to go in another car if finances are that tight.
At the same time, I’d eat the $170 before I paid $165 to send someone else to a track day.
Don’t take this the wrong way but, if you can’t even buy brake pads you should NOT be on a track.
This DE could cost you a lot more than just brake pads.
Try to get ahold of either Hybrid or Innovative. I know between the two there are some spare scooby wheels/tires on rims.
They may be crap but better than chunking up snows.
You can get by on street pads, but like I said before an extra cheap set of pads is good insurance, and you could always return them if you did not use them.
Even if you start to feel fad, just come in early. You do not have to be out there your entire session.
