I am new to this whole ST world and wasn't going to do anything, I ended up getting a few things from Boomba racing to tighten up the shifting and make it more mechanical and fun. I would recommend their shifter and transmission bushings and short throw shifter with no hesitation. There is a recent thread debating the sound symposer delete, another cheaper easy mod to do. I can't comment on performance as I've stayed away from that so far. Good luck!
Steeda hand wrote me a thank you note for only shopping there once, it was even sent separately from the package. Never had anyone do that before. I would also recommend edge auto sport for their customer service
This is a great community and you can buy/sell/trade/learn from members quickly and easily. Read through build threads and other discussions while keeping an eye on the Marketplace. I'll 2nd the great customer service from Edge Auto, bought new parts from them but also had good experiences with other ST owners as buyers and sellers. Welcome!
