What to do next?

So I haven't done anything to the stang in a few years so I was considering the following.
1)Vertical door kit
2)ARH Long tube headers
3)Rear disc brake conversion
4)add 2# boost and get a re tune.
Let me know what you guys think. Stang is running great so I really didn't want to play around with the engine. Was looking at the vertical door kit just to do something that nobody else has.
Thanks,
Chris

My thoughts-
1. Headers (and possibly full exhaust?)
2. Disc brake upgrade (do you have 5-lugs?)
3. More boost
4. Vertical doors....adds weight, requires additional chassis stiffening on convertibles

Other things-
1. Custom seats-Corbeau for example; quality seat, moderate price.
2. Suspension Upgrade

Thanks, for the feedback. I already have full suspension, shorty headers and full un catted exhaust. I have full sub frame connectors and maximum motorsports G load brace. I like my rims so I want to stick with the 4 lugs. According to Realspeed I am kinda at the max a stock block can handle, so I am afraid to add too much more boost and power. I was looking into the vertical doors to do something different that nobody else has.
Thanks,
Chris

don't mess with perfection.

With all of the mods you already have done, short of an new shortblock/tranny, I would leave it alone.

A car today has got to have 4-wheel disc.

Hey Kevin,
I asked Dan over a year ago when I was upgrading my rear end and he said for me it was worth it. I don't think there are many options for the Foxes and I want to keep the 4 lug.
I am thinking now of doing the interior. New front seats (Procar), redo the rears to match and then redo the rear interior quarters. I was thinking of doing LEDs in the dash gauges as well.
Later,
Chris

Big disc brake
More boost
