need ideas

[theWeezL]

I bought my 86.5 NA about 3 months ago. So far I have done the following:

• tuned up with new plugs, wires, cap, rotor.
• put on new 225/50-16's
• Gutted the Cat (no not the feline, the converter)
• new Magnaflow Performance XL 2.5 in dual 2.5 out (which I hate btw)
• polished the wheels
• lowered it 2inches
• added a new front lip
• front strut bar installed
• reupholstered door inserts, shift boot, console cover, and E-brake cover.
• added a new head unit, 4 new speakers and an amp and sub box
• put in white faced reverse EL glow gauges
• short shifter mod
• TEMS diag mode mod
• JDM look alike tail light mod
• added stock rear spoiler
• cleaned and detailed inside and out including under the hood
• removed, sanded and repolished the body mouldings
• swapped out lights with diamond cut lenses and H4 superwhites
• fabbed mesh grills
• modded AFM

The car runs great, drives smooth (except when the targa is out, where it developes an obnoxious shimmy around 65 and goes away around 85), stops ok. All the electrics work properly and hood and hatch stay up.

Thats all I can remember right now. I am planning on putting on CD'd/slotted rotors and semi-met's when funds allow. Im also right now having a targa brace fabbed (laser cut front and rear plates with 1" tube bars connecting front to back). What Im wondering is anyone has an ideas for other mods or upgrades that would be relatively cheap, say $200 or less ideas. Obviously that means no engine/trans swaps, and no TIEN coilovers...lol.

1 piece driveshaft? Header pipe? does anyone make a TB spacer for the 7M? Electric fans? all valid ideas, and Im hoping someone will post up their experience with those mods (sources, trouble spots, results) and possible help me come up with ideas I havent thought of yet. Help me brainstorm it folks!
