Keep an eye on this up-and-coming builder: MLR Porsche.
I met Mark and his sons years ago and have been following their work ever since. A good friend of mine has had several projects done by them, including some standout 993 Speedster builds and their take on the 996 platform. I know of two Speedsters that recently changed hands at premium prices $$$—purely because of the exceptional quality and craftsmanship.
I've just shipped my 2002 996 Turbo over to Mark and the team for a full bespoke rear-wheel-drive conversion. This will be their take on a Turbo RS if Porsche ever built one. The plan includes:
Ground-up seam-welded tub
Custom paint
GT3-updated suspension
Fully bespoke interior
Carbon fiber hood, roof, and other bits for weight savings
Engine bumped to around 520 hp and much more.
Since I'm in California, "traffic", and I have other manual Porsches, I went with the Tiptronic (which they'll upgrade, including steering wheel paddles). It'll be my daily driver—reliable, fun, and dialed in just right.
I'll drop video and photos as the build develops. If you're into custom 911s, these guys are the real deal.
