Also looking to trade or sell my Progress rear sway bar.
If you want FWD oversteer, get a new Civic Type-R lol. In your case tho, you gotta accept its a FWD, oversteer is not common for us, and trying to force it won't end well. What you could do is get a 2nd set of wheels and put some R-Comp tires on them, and use your Federal tires on the rear. You'll get oversteer, it won't be fun, it will wreck your tires, and be mostly unpredictable when pressing the limits. I think ultimately your Federal tires just suck, that's my 2cents. If your serious about grip and getting even a tiny bit of oversteer, start with really sticky street tires. I HIGHLY RECOMMEND Firestone Firehawk Indy 500's as a durable street tire with boatloads of grip, on the edge of RE71R's which is the autocross/track tire of choice. Also, it sounds like you need to understand how to get oversteer in a FWD or something with a FWD biased AWD system. You have to push the momentum at the right time in exactly the right way. On gravel, I can get some oversteer in my Mazda 3 but that takes practice and training too. Our chassis just wasn't built for oversteer, please don't spend oodles of money trying to get oversteer. Used FRS/BRZ are cheap now, oversteer all you want in those?
