I had better luck sourcing everything out separately. It was much cheaper too. The normal kits didn't include everything for my cars. After sourcing EVERYTHING out I came in the same price, or cheaper then the kits.
Rockauto is the best, if you can get all your parts shipped from the same place, or 2.
Summit racing, and ebay ofcoarse too. Even the local parts stores have better deals in store then online on some items. Just need to research em.
