There are are some interesting upgrades coming out in the not too distant future for the GT4. Choices are good. Makes hanging onto the $60k delta for not trading to a GT3 more appealing.

Quite a bit, everyone's favorite new track car is getting quite a bit of attention:
Things we're testing now on a Spyder Build we're doing.
991 GT3 Plenum and TB
Prototype Big Air filter box (less pressure drop)
X51 cams
X51 heads (they're a little different than stock GT4, and we're working on porting the stock heads to be better than X51)
Catted/non catted side pipes and high flow valved lower dB muffler (will work on any 981, and bolt to any race header)
The catted sides and muffler are going to select beta testers for feedback in the next few weeks, both local and extended Dundon family. The air box and 991 GT3 manifold adapters we're working on the tune on the Spyder and to ensure they are as efficacious as we expect.
On the engine side I spoke a bit at Smokies:
Phase 2 of the Spyder build is 4.5L bore and stroke. The fruit of this will allow us to easily make 4057cc (4.1L) engines with just a bore and big piston swap, 4167cc (4.2L) with stroker crank and new rods and 4.5L for the full meal deal. First parts are finishing design/mfg. These parts also apply to other 9A1's including the 991 GT3 and RS, but have to fix the valve train first...

Not feeling up for being a guinea pig again?

Went and visited my GT4...here's the driver's side rear after replacing two panels. This resulted from impacting a barrier with the wheel/tire which was pushed into the wheel well body causing a panel to deform and need replacement.

Guilt. Guilt is what I felt today for owning a German car.
