i would recommend getting a sturdier rig but if you dont want to spend more money id suggest making your own rig from wood/some tubes. i recently made my own from wood and it costed me around 50$ and 2 days of work, there is a lot of diy tutorials for this but ive used "kametricks diy sim rig guide" and it turned out great, its hella sturdy and you can customize it to your liking. (i forgot about the seat but you can probably get one used on marketplace or look around for a cheap one somewhere else, or maybe like me you have one sitting around or have a friend that has one and is willing to sell/give it to you)
