Continuing the buildup on project: The Show, Chassis by Aaron Iha takes fabricated sheets of steel and assembles the chassis, turning it into a rolling work of automotive art. Last month we showed you how the frame was designed and came to life, and in this installment you'll see the wild spindles, control arms, ridiculous 9-inch IRS, Wilwood big brakes, and Bonspeed wheels and Nitto tires meticulously being placed on the chassis. Rather than just put an obvious caption with a photo, we went to the man himself, Aaron Iha of Chassis by Aaron Iha, to tell us the reason/benefit of why he went so extreme on this build. Don't miss next month's insight into project: The Show's powertrain, as we're certain you'll be impressed with the throttle-by-wire, high-horsepower blown LS-engine. Oops, we may have said too much. Check out issue 3, where Chassis by Aaron calls up a Chevy C10 from the minors and gets it ready for the Show.
1. Aaron, after spending 11 weeks creating the frame and chassis components, it was a relief to see the frame off the table and onto the jackstands, ready to be assembled?
2. You used adjustable QA1 shocks, both front and rear, are they your preferred dampener or were they just a better fit for this application?
3. Last issue you told us the lower control arms were fabricated from 1/8-inch-thick steel, how thick/strong are the upper control arms?
4. What type of mount is used to connect the spindles to the control arms?
5. What brand/part number did you use for the front and rear airbag?
6. For the front suspension, was it your initial vision to have it look industrial and heavily mechanical?
7. Did you have the Wilwood big brake caliper specs before you built the spindles? Did the brake kit bolt on easily? When choosing big brakes, what advice can you give our readers?
8. Moving to the power rack-and-pinion, is that from a Mustang II?
9. Did you fabricate the custom end links and simply incorporate the heim joints into the design?
10. The front suspension is pretty sick on project: The Show, is it your most "advanced" design to date?
11. Out back, why go with a Ford 9-inch instead of a GM rearend?
12. As we see you installing the rear control arms, what other benefits will an independent rear suspension make on the 42-year-old truck? Have you ever fabricated every single piece of an IRS like on this truck?
13-14. How much travel will the independent rear suspension have using the QA1 shocks and airbags?
15-16. Taking a look at the rear spindle setup, it reminds me of a sandrail. Does our background in sandrails and quads influence your design and "built-to-last" engineering mentality?
17. How did you come up with the inboard brake system for the rear? Who built the inside axles for you?
18. For the outer axles, who did the fab work on those? How do they mate to the spindles?
19-20. Looking at the IRS with the ‘bags inflated and then deflated, it's awesome to see the huge travel and flexibility of the dual U-joints. Were all of those dimensions and specs built into the original engineering program, or did you create that setup/design afterwards?
21-23. On any ride, the wheels and tires can make all of the difference. Can you give our readers some tips on taking some quick measurements to get the perfect-fitting wheel and tire combo?
24. Once you've taken the wheel/tire measurements, can you just punch those specs into your program to get the proper camber/caster and toe?
25-26. On project: The Show, the Bonspeed wheels and Nitto tires look amazing in my opinion. What are your thoughts on wheel/tire choice? Were you trying to get a big lip on the rear of the truck when taking measurements?
27-30. Aaron, once you saw the chassis down from the table and on the ground as a rolling frame, what kind of feeling was that? Were you relieved that the project was making progress or were excited to see your creation go from thoughts in your head, to design, to fabrication, to finally assembled?
