Lateral-g Forums - Speedtech Performance NEW First / Second gen SubFrame

SPEEDTECH PERFORMANCE
Monday, March 15, 2015

You may already know Speedtech Performance has acquired the rights and production of the Ironworks CAD designed full chassis for 67-72 C10 Trucks, 55-57 Chevys & 68-72 Chevelles/GM A-Bodies. What you may not know is we also currently have NEW Front Subframe & Suspension packages in the works for 67-69 F-Bodies, 68-74 X-Bodies & 70-81 F-Bodies.

Here is the juicy part. Speedtech Performance contracted Ron Sutton to optimize the front suspension & steering geometry, the way only he can, on all the new Speedtech Performance chassis and front subframes. For the first time, you can bolt in a chassis or front subframe with Ron Sutton Race Technology optimized geometry.

Ron said, “This was a tough project, because we needed to achieve the optimum front dynamic roll center for any suspension strategy the customer wants to run ... and we did it ... it turned out perfect. This combined with the best Ackerman of any available front end, optimum camber gain and minimal jacking effect ... makes these the best handling, steering & driving chassis and subframes available. They are an upgrade from Speedtech’s current product offerings and frankly any full chassis or front subframe in the Pro Touring market today.”

The front suspension is based around the NEXT Generation of the ATS Forged 7075 Aluminum Spindle design that now makes it possible to have what Ron calls, “The best possible multi use suspension package available.” Ron stated the Next-Gen ATS spindle in its new configuration offers “Better geometry than any Corvette or Corvette copy spindle.”

Some of the many technical advantages of the new ATS Spindle & Speedtech Chassis/Subframe Geometry:
• Reduced KPI/SAI angle
• Requires less caster to achieve optimum full tire contact patch
• Significantly less scrub radius for improved grip in tight turns
• HD C7 hubs & bearings standard
• Improved design steering arm with max Ackerman
• Optimum rack & pinion location
• Amazing 95% Ackerman achieves optimum tire slip angle, significantly increasing front tire grip
• Virtually Zero Bump Steer (.005”)
• Up to 30 degree turn angle (tire size dependant)
• Roll center achieves optimum dynamic location for low, mid & high travel suspension strategies
• Increased shock length allowing higher suspension travel
• Excellent .76 motion ratio for improved shock response & control
• 3-Piece splined Speedway Engineering sway bar standard – Wide range of rates available
• Excellent for Autocross, Road Course and Street Driving

The other exciting part is that we have arranged for Ron Sutton to provide our competitive clients custom Autocross/Track Day suspension combinations & tuning support on an individualized basis (for a small flat fee) for the full line of full chassis & front subframes. Ron Sutton Race Technology is an authorized dealer for the entire Speedtech product line.

We are REALLY excited about this game changing chassis and front subframe/suspension line and although it is a couple months from being ready to ship we just felt we should let you know. We are taking pre-orders through Speedtech Performance and Ron Sutton Race Technology starting March 15th. Once the chassis & subframes are in production, they will be available through all Speedtech dealers. Stay tuned for pricing and other options.
