What is your favorite mod?

[lskolnick]

For me it's the glass window top. That plastic window is so annoying.

Actually having the time to drive my car is my favorite

Working two jobs leaves precious little time for anything

Just curious, what is the SAI delete?

Removal of the Secondary Air Injection system.

The SAI is an air pump that injects air into the exhaust for about 90 seconds at cold start up to help the catalytic converters get up to temp faster and to reduce cold start emissions.

The air pump itself is on the passenger side of the engine compartment above the intake manifold. It kind of looks like an alternator but without a pulley.

When you start your car cold, listen for a motor whine in the background for a short time. That's the SAI pump working.

Thanks. Why remove this pump if only used the first 90secs? Weight?

Because the system (air pump, vacuum valves, electronic valves) is prone to issues that trigger a CEL and will cause cars to fail inspections in some states. Even when it seems to be working properly, the system may not show "ready" status in the monitors and cause it to fail.
Ironically, I actually had my system working flawlessly after years of tracking down and fixing issues when I decided to ditch it.

What lights are those, Particlewave? (They look awesome)

[maddogxx]

+1 on the lights?

Best for long distance is the foot massaging pedals (you have to drive barefoot to really appreciate)

For top down driving, the Toupee securing head screws

I do like the subtle exhaust note from the cat delete pipes

Thanks.
I built them using Fred's bi-xenon projectors. They are dual projector (main is bi-xenon HID, smaller is LED) with CCFL DRLs.

[clickman]

Function: 9x7 short shifter
Form: Fred’s bixenon headlight conversion. And I rarely drive the car at night...

Hard to say. The glass window is really nice, nice to be able to see other cars in the rearview mirror. And I think the 03 top is a little better quality.

But I have noticed that the UDP and the inexpensive cat back muffler from Amazon make the car ALOT more fun to drive.

And then there's the after market double din stereo, mine's Pioneer. Nice sound! I didn't have Bose.

And fresh tires!

As I said, "Hard to say."

[Ciao]

The most recent mod until my next one; for now its the switch to Turbo Wheels with BF Goodrich Summer Performance tires and the K&N oiled air filter

[thstone]

Running the square tire setup (8.5" wheels and 255 tires on all four corners).

Improves the handling immensely.

Safety note: Increasing the front tire width from 205 (or 225) to 255 causes the handling to transition from the stock understeer condition to an oversteer condition. Front and rear adjustable sway bars are needed to bring the handling back to a neutral balance. Don't try this mod without the adj sway bars and some knowledgeable help in setting them up.

I just got the Tarett bars and ran my first weekend with them - even with the "stock" 225/45/17 front 255/40/17 there was so much more mechanical grip. I took 3 seconds off at Carolina Motorsports Park, although that might not be the best comparison since it was a year since my last trip there. However I am going to Roebling in a few weeks, and so I'll know if I really do have more grip, or if it was just the improvements I made over the last year.

Depending on how that goes, I may give the square setup a try...

My favorite mod - that's hard to say. Most of my mods are reliability and safety. Even the bars I mostly got to see if I could reduce tire wear on the edges. probably my FD Mostorsports "Fister" exhaust mod is my favorite mod

And a quick edit: or Ben's ball bearing shifter.

[Booker42]

Short shifter changed the entire experience of driving this car. No question #1 for me.

The two "D's" are up there too. De-amber and De-snorkle.

[DWBOX2000]

That's a tough one. The lowering springs change the look. The short shift really changes the driving feel and the Beluga sounds wonderful ( thanks Steve). I like them all. LN gave me peace of mine.

Mind not mine.
