Field Report: 'Make or break' your race car with these pro tips.

12/03/24 • 17 min

Suspension dampers (aka shocks) are well-established products, so in this day and age, surely anything you get off the shelf from a high-end brand should be ready to roll, right? Wrong.

Andre Nader of DNA Autosport & Modal Suspension explains some of the variances that generic off-the-shelf products, no matter the price, must operate within compared to dialling in custom bespoke suspension for your car, tyre choice and driving style.
He runs through some key points around ride/suspension frequency and its relationship to spring rates, as well as what a driver might be looking for in order to know that his damper setup is sub-optimal, which includes hopping or skipping on the surface of the race track and instability under braking.
Why remote reservoirs are used, how a 'safe' car balance isn't necessarily fast and how trying to cover up the poor suspension with extreme alignment/setup changes is a slippery slope is also explained.

Field Report: "I didn’t know why, I just knew I needed an AE86”.

Back when tidy AE86s were still going for $3,000 AUD, Ben of Third Strike Fabrications knew he needed one in his life, and 4 or so engine swaps later he gave us some insight into his build and the Toyota AE86 Corolla Levin/ Sprinter Trueno platform in general during the World Time Attack Challenge.

Ben touches on known issues relating to the rear suspension, why a K24 instead of the 4AGE or 7AG (which he has tried), retaining variable cam control (VTEC), future fine tuning plans and more in this interview of what was certainly one of the tidiest AE86's we've seen in a while, including (but not discussed) it's full titanium exhaust system made in-house by Ben and his team.
Basic rundown:
Engine: 'Built' 260hp K24 with Drag Cartel aftermarket camshafts
Electronics: Insight Motorsport wiring, EMtron KV8 ECU
Transmission: 6 speed J160
Fuel: Dedicated E85 build
Past engines: 4AC, 4AGE, 7AG

129: Is It Time to Get a 3D Scanner?

New technologies have enhanced our ability to create stronger, lighter, and better components since the earliest days of motorsport. Recently, we've been seeing another great leap forward in tech, with the 3D scanner being one of the main drivers behind it. Now that these devices are only getting cheaper and easier to use, is it time you picked one up and started pushing the boundaries of what you can build?

On this episode of Tuned In, we sit down with Gabrielle Williams of Peel 3D, one of the bigger players in the rapidly evolving 3D scanning space.
Straight out of high school, Gabrielle joined the US Navy and found her way into a position as a nuclear operator aboard an aircraft carrier. After her tour finished, she gained a mechanical engineering degree and found herself working for Creaform and its sister company, Peel 3D.
While Creaform is focused on high-end large-form scanners, Peel 3D is aimed at the consumer market — in other words, us. In this conversation, Gabrielle talks through the basics of the technology, covering how different systems work and which one would suit your application best, why the prices vary so wildly between systems, as well as the metrics that matter like frame rate, field of view, and data points.
Gabrielle also breaks down some of the ways we can be most effective in the workshop with a 3D scanner, where the sweet spot is price-wise for the average enthusiast, and what to expect from this technology in the coming years.
You might not have considered 3D scanning before, but now that you don’t need to take out a second mortgage to afford one, is it time to consider adding a 3D scanner to your workshop?
