Wipers on NASCAR

[Jim B]

I recently purchased a SalvinosJR Camaro NASCAR kit, and on the whole I'm impressed with it. So, because of this purchased, I have been watching some highlights of recent NASCAR races on YouTube. I just finished watching the highlights from the race at COTA, and I noticed that the cars have a single wiper on the windshield (something the kit is missing). Is this new? I don't seem the remember NASCAR cars having wipers. Do they only have them at certain tracks (road course vs. super speedway)?

NASCAR has starting using wipers on road races. The intent is to run in the rain as long as its not a heavy downpour with lightning.

Well, that makes sense.  Thanks.  Saves me from having to source a wiper.  Wonder if anyone makes a road course conversion kit with wipers, rain tires, and whatever else is different.

I believe Jim Rodgers (the JR in Salvino JR) 3D prints some stuff for their kits.

I know he had a 3D kit for the Le Mans Garage 56 car (minus the lights), but I don't know if that's still available.

Forgot, Jaye's Model Garage has several parts for the current cars including the wiper. He parts are really good quality and fit.

Thanks.  Never heard of them.

So, what spoiler do they use on the road/street courses?
