So this winter, I was bored and was reading some product reviews here at 
, and I came across Hib Halverson's review of the hatch vent. I thought I might try one, so I did.
I used it today for the first time, about 75 out. WOW, so...much cooler in the interior of the car. Windows down, hatch vent in. Cuts down on the wind noise and buffeting at high way speeds. I cannot believe the difference, I think my targa is going to stay in more often now.
I highly recommend if you don't have one.
Also, I performed by own 4 wheel alignment and set the car up fairly aggressively for street use. (I auto-x and don't switch to slicks, too much $$$). I dialed -.5 degrees of camber at all four, reduced the caster to around 5.4. Rear toe is set just to max. factory specs. + or in. Front I dialed in a toe setting of ZERO.
Took it for a drive and immediately could feel the difference. Turn in is much more pronounced and quicker. Grip is higher and the car definitely under-steers less. I did some 8/10 cornering and further confirmed this. Put it this way, before (especially with stock 255's up front), the car had a good bit of understeer at the limit. In 8/10's cornering the nose does not push and you get the sensation of the rear pushing the front into the corner more, even more so with throttle input. I'm anxious to see how the car reacts at 10/10's cornering. I still expect understeer at the limit but it will take longer to reach that understeer and it should be less pronounced. The turn in is almost amazing. Still get a hint of delay between turn of wheel, feel chassis take a set and turn. I maybe able to improve this in the future....stiffer springs front and rear, Z07 front sway bar, maybe re-valved shocks,etc...
FYI, I'm running 275/40/17's at all fours currently.
