It seems like just yesterday when the "FAST 90/90" was the biggest, baddest combo on the block. Now, with 400+-cubic-inch motors, forced induction, and huge horsepower being the norm, FAST has stepped it up with the new LSXR 102mm intake manifold (PN 146102). Like the old FAST manifolds, this is a three-piece modular design that can be taken apart to allow for porting; but for the new LSXR, each individual runner can be removed for modification. The LSXR will accept a multitude of throttle bodies, from 90-102 mm, and has integrated nitrous bungs. In testing on a stock LS3 engine the 102/102 combo picked up 14+ flywheel horsepower and 11 lb-ft of torque over the stock unit.

Adding a set of the new BMR subframe connectors to your Pontiac G8 will not only give you improved handling and response, but it will help reduce the rattles and creaks that occur after many miles of hard driving. BMR has not only designed a super-strong set of 0.120 wall, triangulated, CNC-cut subframe connectors, but they have made them a complete bolt-in solution using factory drilled, pre-existing holes. These bolt up to the front subframe, the carrier bearing location, and the rear subframe for a greatly improved ride. Available in either Black Hammertone or red powdercoat, these will look great on any G8.

Better Than New
Let's face it, no third-generation F-body survived this long without taking some pretty good abuse. If you are looking to tighten up your frontend, Spohn Performance has got you covered. The new Spohn Precision frontend rebuild kit features CNC-machined, forged, and treated-steel housings, chrome-moly studs and is plated in a silver zinc finish for long-term reliability. It comes with a new centerlink, idler arm, two inner and outer tie rod ends, and a set of Spohn Extreme-Duty chrome-moly tie-rod adjusters. You can order each piece individually or as a kit and can paint them to match your specific build.

Corsa's Got Your Back
If you are lucky enough to already be tired of your new ZR1's stock exhaust, Corsa Performance has got you covered. The newly redesigned axle-backs are not only 4 lbs lighter than stock but flow an amazing 22% more exhaust. According to Corsa, the new systems deliver an immediate uncorked rumble at idle with a race car-like roar at full throttle. Inside the cabin however, you can expect a quiet, drone-free ride thanks to Corsa's "Reflective Sound Cancellation" technology. With two different versions for both the ZR1 and ZO6, a 50-state emissions-legal badge, and a lifetime limited warranty, what's not to love? If you are looking to go even further--add the 3-inch cross-pipe (PN 14173) and hang on.

Go Billet Or Go Home
The days of weak GM electronic transmissions are coming to an end and thankfully there are converters to go along with that change. The new 4L80E billet multi-disc offering from Circle D is all business, touting the largest three-disc design on the market. To go along with that, they have added a rigid billet front cover and a special carbon-based lining to maintain great holding power. "We are so confident in this converter that we dare you to break it. It will hold full, wide-open throttle lockup in cars up to 1,000 hp." To go with that claim you get a three-year warranty and one free re-stall. Circle D ships each converter with all the bolts, washers, and Loctite needed for an easy install.
