GMG 4.0 GT3/RS kit
GMG introduces the GMG 4.0 Liter power kit for the GT3/RS 3.8 and 3.6 liter engines. The kit consists of the crown jewel our very own "true" 4.0 liter billet crank shaft. forged con rods, pistons and cylinders made by Mahle with our own piston design.
We properly designed and engineered a true stroker engine much like the factory has with the new released 4.0 liter GT3RS yet we were able to improve upon what a production car would use in terms of the hardware. The crank shaft itself is made by a F1 supplier in europe and utilizes the latest technology in crankshaft design this is our very own design. Some of the key features of the crank shaft include:
Billet is stronger than a forged crank shaft
Lighter weight - less rotational mass offers improved engine response.
Can be used and tested for both high rev'ing naturally aspirated engines which can see over 10,000 rpm or high boost turbo applications making in excess of 950 "real" bhp.
New main bearing oiling design for high load and high rpm use.
Each crank shaft is meticulously micro polished - balanced and blue printed and matched to the con rods as well as the pistons and flywheel/clutch assembly.

GMG 996 GT Battery Tray
It's a well known fact that the original equipment battery supplied by
Porsche is good for little more than 2 years of life.
How many times have you parked your 996 for a few days only to return and

Optima batteries DO NOT fit into the standard Porsche tray and just
throwing the battery into the existing tray is dangerous. Our GT Tray is made
of aluminum for years or durability, CNC machined and powder coated satin
black for an OE look.
Available with or without the Optima battery.

LEGAL FOR ALL CLUB RACING AND TIME TRIALS- SCCA-PCA-POC-NASA
Great for cars that have upgraded Audio system. Recommend with use of Optima Yellow Top
