What next?
 

This spring I am putting on my 4.10 gears along with my bbk headers. In addition, I am buying some nitto 555's for the rear. What would be next? Are there really any more bolt ons that I don't currently have?

I am not going to go nitrous or FI just yet. Also, I use the car as a daily driver and do not currently take it to the track. What would be the next best bang for your buck power that I can add to the car? Would an actual tune bring me much more? I assume it wouldn't be worth the money that it would cost to tune it.

Just wondering, anyone got any input on the topic?

you should notice a big enough gain from the 4.10s... id actually suggest instead of shorty headers, longtubes... they are usually able to pump a few more ponys out of ur car. and YES a tune is worth the money. in my car my without anytune whatsoever it made 222 rwhp, with a custom tune i am up to 250 rwhp now. the next thing you could do after gears would be a bit of a cam.... u have enough gear for more lift:D

Yeah I know about the longtubes but I had already gotten the shorty's.

Cam is what I was thinking as well. But otherwise, there really isn't a whole lot to do, is there?

You've got just about all the bolt ons...like 02 said a cam + some heads. Although, if you plan on going with a blower later on the NA cam isn't going to help. If you are going to do heads and cams you might as well just get a blower though. It's not going to cost much more.

Other than that some good suspension will help you out. I'd add subframe connectors and a set of LCA's to your list.
