    Custom Axles

    I have been having a hard time finding a place to get wider axles. I found a post on Pennocks, http://www.fiero.nl/forum/Forum2/HTML/026747.html ,
    where you say "I've got great sources for the axle stretch . . . just a few blocks from my home"

    I need axles to go with my Held suspension 4" per side track increase. I am also using Archie's LT1 kit so the engine is moved 2 3/8" to the left. This results in the long axle needs to be 6 3/8" ( 4 + 2 3/8 ) longer than stock and the short axle needs to be 1 5/8" ( 4 - 2 3/8 ) longer than stock.

    Let me know what you can do.

    Thanks

    Do you have your axles yet? I read about another 355 builder who got his axles from PSI Engineering in Clearwater, Florida but I haven't been able to track down the phone or address for this company.

    You don't need Stretch axles for the LT1...Right? I am planning on taking my Spyder in to Archies in March....for an LT1 Swap...he hasn't said anything about stretch axles. I really dont want to stretch them, as finding parts will be a pain!!! Hopefully you guys are just talking about needing them for the wide track setup...I HOPE I HOPE I HOPE!!!

    If you are installing a LT1 into your car you will need new axles. However, Archie bought 25 sets of custom axles from his supplier for LT1 swaps so he will have new axles for you in stock. Archie has a lot of experience so don't worry about him not being able to handle your swap. The axles I need also have to accomadate the wide track suspension and Archie only has standard fiero track lenght axles for LT1 swaps.

    Axles, Brakes and rear Suspension

    I had to make my axles longer due to the 355 Ferrari rebody I completed on my car. The axles are 4 inches wider on each side. I used a PST (Precision Shaft Technologies), Clearwater, Florida, 727-XXX-XXXX to cut, lengthen and rebuild my axles. I beefed up my hubs to handle a larger bolt pattern and larger splines by using a set of S-10 4X4 front hubs mounted to Olds Cutlass Ciera uprights. I had to use the hub side CV joints and 1999 Buick Park Avenue axles mated to Fiero axles. The Ciera uprights are stronger (more meat around the bearings) than Fiero and can take the stresses of the 3800 or 350 V8 conversion. The set up was topped of with 12 inch Wilwood brakes and “Bump Steer Correction” lower swing arms and coil over shocks, 350# springs and a 1” anti sway bar from Held Motor Sports. My theory is that if you are going to go fast, shift hard and corner correctly. I thought it best if I could stop on a dime and not have a desire to swap ends, as in the case with the OEM suspension.

    Bill of Materials

    89 Cutlass Ciera Upright Assembly (casting for larger bearings)
    88 – 89 Chevy S-10 Front Spindles and CV Joint Assembly for
    Front Wheel drive. (bigger bearing, heavy-duty splines, larger CV joints
    Ciera Upright Assembly machined to fit S-10 Parts into Casting.
    Ciera upright castings $10.00 each side
    S-10 Spindles and brakes $25.00 each side 4.75 bolt circle.
    99 Buick Park Avenue Axles, for used with 3800 transmission
    Custom axles, PSI Engineering $400.00 Pair



    Braking System 12” Wilwood Disk Brake Package $2,855.00
    2 - 4.75 Bolt Circle Aluminum Hats
    2 – 108MM Bolt Circle Aluminum Hats
    4 - 12 Inch Vented Rotors
    2 - Caliper Bracketing Rear
    4 - 4 Piston Calipers
    Two – Manual Piston Emergency Brake Calipers
    Semi-Metallic Brake Pads, Rear
    High Friction Racing Pads, Front
    Stainless Steel Braided Lines to Match Wide Track Options
    High Volume GM Truck Master Cylinder
    Wilwood Proportioning Valve, Front Suspension and Brakes

    This fully self contained front suspension system for the '84-'87 Fiero comprises a replacement fabricated cross member with tubular upper and lower control arms. The spindles are fabricated uprights with bolt-in bearing/hub assemblies. The upright design resembles those found on some formula type racecars, being very strong and light, they allow a reduction in un-sprung weight and thereby improve handling. The 325# springs and HAL shocks are of the coil-over variety, with a large assortment of spring rates available and while the standard shock is a three way internally adjustable unit, there are other shock options including externally adjustable units. The standard Fiero steering rack is retained and the package is designed for use with Fiero replacement or standard sway bars (not included). I purchased an anti sway bar from Held Motor Sports in a 1 ¼ inch configuration. Control arm bushings are polyurethane and grease fittings are installed at all pivot points for easy lubrication, eliminating the annoying squeak normally found in urethane bushed suspensions.

    The system features purpose built geometry with excellent roll center and camber characteristics. I had mine manufactured to a width of 8 inches wider than stock in the rear and 4 inches wider than stock in the front to fit the 355 body conversion and OEM Ferrari wheels. It incorporates anti-dive and is bump steer corrected. Ride comfort can be preserved or improved, or full race handling is achieved with the correct shock dampening and 325# spring rates. Of course changing ride height and or weight jacking (or transferring) is a snap with the coil-over system.

    Lateral acceleration figures in excess of one 'G' have been recorded with this system, using street tires and 325# spring rates. The system will not work with the standard Fiero brakes, the 12" Super Duty Wilwood brake system is used. High quality black powder coat finish is standard on all fabricated parts in this package. This is the ultimate Fiero suspension system.

    If you're not confused, you're not paying attention.
