Psi-Fi Traction Bushings
yes. my car is my daily driver too, and they do help. they actually make the ride a little softer, where you don't feel the bumps quite as much. and if you ever need to get on it to pass a car or have a friendly light to light race, you'll see noticably less wheel hop. they're not that hard to install now with the exchange program that psi-fi has. you can order them already installed in a set of new lca's, and you just install those and send them back your stock ones. it's not too bad and shouldn't take you too long. just be sure to get an alighnment after you install them.
it's awesome. if i had the cash i would get a 57 trim from them in a heartbeat. it's a great set up, easy to tune, and they're great about sending new maps to adjust for new mods after the kit is installed.
you don't get a big turbo upgrade to improve gas mileage. i don't know what kind of mileage it does get, but i wouldn't think it would be any better than stock considering the size of the injectors that are needed.
warranty? we have one of those? lol...yea i think it would be safe to say that it would be gone with any turbo upgrade.
