The car handles great for nealy 4000 lbs. My shop recommends the Eibach springs over Steeda. I trust the shop with everything and so far the Eibach have been great. I love the ride height and the performance has been everything I can handle; still have not found the limit. As far as wheels and tires I am either getting some GT 350 wheels with continentals in the front and MT ETSS (used), or if that doesn't pan out the way I want, I will settle on some Apex sm10 rears with Nitto 555R2 for now. I have some other wheels in mind for the future but alreasy spent 60k on the car, 11k on the blower, and another 7k on other mods. I sometimes forget I also did billet oil pump gears and crank sprocket along with the headers, suspension, etc. Shit, I should have just bought a C7 Z06 for all the money I've spent lol
