Had an LS but manual before I traded for the SS/SC, I liked it, has potential to put decent numbers but that depends on your wallet or purse lol. Congrats and enjoy, just do not ride up to SS's, especially an SC and think you are just as fast. Not really saying ya would but I have had a few think they do, its annoying as hell.
I have the performance exhaust on my SS and love it, I sure it may sound alittle different but its a good choice. I would suggest an intake aswell than maybe work on getting it lowered. Eibach Sportlines well give it a very nice drop and stance, definitely improve handing and the look. If ya need a new set or, should I say, a slightly used set of LS wheels and tires I got 4 in my garage cause I put different ones on the LS but never got them off before I traded in. If you would like a set of SS headlights from an '07 I got a set of those too haha, in great shape because they were on the car for alittle less than a month. Difference is they do not have that orange lens in them or whatever. Just putting it out there
Enjoy the car!
