Avoid the headache of trying to drill out broken exhaust bolts on the Turbo, GT2 & GT3 engines. A CNC milled plate indexes precisely off of the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR068 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR068 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with the supplied M8x1.25 tap. Kit includes aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.

For the current generation of Porsche DFI Engines on 911/997/991/ Boxster & Cayman. (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR069, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap. Kit includes anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Also includes our SR065D drill guide.

For All Carrera & Panamera Models 2009 onwards, except 911 Turbo or GT3
