2008 Ford Shelby GT500 Suspension Upgrade - Project Vapor Trail
Steeda's Coilover Suspension And Watt's Link Transforms Project Vapor Trail's Handling (And Looks)
For those rare occasions that PVT might see the track, it seemed wise to put safety first and add Steeda's two-piece driveshaft safety loop, which uses existing bolts in the floorpan and transmission mount to position two loops over both halves of the stock two-piece driveshaft. You can install the loops without removing the driveshaft; on a GT500, you may need to slightly clearance two bolts on the transmission crossmember. It goes on easily, and you'll feel a lot safer knowing it's there. I do.
The Steeda unit clamps to the axle housing, so you have to unbolt the factory sway bar and remove the stock Panhard bar to make room and lift the Watt's into place. Once it's attached to the axle, the Watt's bolts to the chassis right where the stock Panhard bar attached.
Despite its impressive construction and handling benefits, it really is a straightforward install, and Steeda's detailed instructions walk you through the details and torque specs. Before clamping it all down, Steve used a digital level to make sure everything was parallel to the ground.
Once the Watt's was mounted, Steve and Matt were able to adjust PVT's rear roll center and center the axle in the chassis thanks to the Watt's adjustments.
While the car was on the rack, I noticed that the rearend was off-center from the factory, which was readily apparent thanks to the wider rear tires. Steve used a straight edge against the wheelwell to measure the space between the wheel and fender, and Matt easily dialed in the adjustments.
Being a full-fledged Shelby Melvin, I'm trying to keep as many stock parts as possible. I'm quickly running out of garage space, but so far, the stock speakers are the only parts to go in the trash. This latest round of mods produced a pallet full of stock gear. The new parts delivered a balance of a smooth ride and sharp handling that you wouldn't believe possible from a car slammed on 20s. Steeda's adjustable suspension could just be my favorite mod so far.
With all the suspension mods complete, Matt used Steeda's computerized alignment rack to dial in PVT for a proper balance of handling and tire wear. He even compensated for Florida's crowned roads with 1.2 degrees of camber on the passenger side and 0.9 degrees on the driver side.
