Alternative to stock strut replacement Options

[YourOldPalElmer]

Hello there! Hope you’re doing well. I already brought this up to the FB group, but figured I’d ask it here if there was possibly a different audience/knowledge base. What are our options in the current day (2020) for performance shock absorbers for the celica. The reason I ask is, I’m currently rebuilding a GT to autocross and while it certainly would be easier to just get coilovers, it would also throw me out of my target stock class. I know you can get KONI inserts for the non-sport spec suspension, but I don’t know what cartridge size To get, or If they even work for the rest. I’ve also heard whispers that you can use the same era corolla struts, and my question with that would be if you can use Celica top hats, and if the ride height was the same. Any options I missed? Am I an idiot? Aliens? Lemme know, thank you for reading. Have a nice day!
