![Mikes Turnkey Rock Bouncer Reveal & Walk Around - Wide Open Design
Its always fun to watch a guy see his finished buggy for the first time. The owner of this rock bouncer has waited a very long time to finally see it complete. Check out this video of the newest turn key being revealed along with a walk around of the rig.
See photos and specshere: https://wideopendesign.com/blogs/custom-builds/the-build-blueprint-behind-the-reveal
Installing a custom-built chassis is just the starting point—finishing the build into a performance rig is where the challenge really begins. This walk-around of a recent turnkey rock bouncer highlights the level of integration available to the enthusiast, featuring a massive [01:38] Mast Motorsports V8 putting over 700 horsepower to the ground through a rock-solid Turbo 400 and an Atlas transfer case [06:27]. This Dream Build also showcases our [11:42] Radflo suspension setup, valved and sprung for maximum traction on the steepest climbs, alongside our heavy-duty Magnum knuckles that provide unmatched durability [01:03].

![How to Calculate Spring Rates Without a Scale - Wide Open Design
Trying to figure out the correct spring rates for your buggy or rock crawler? In this video, Adam breaks down a simple method for calculating spring rates at home without:
* corner scales
* suspension software
* complicated geometry math
All you need is:
* your shocks installed
* one pair of springs
* a tape measure
* some simple calculations
We cover:
* spring compression measurements
* supported vehicle weight
* dual-rate spring setups
* crossover adjustment nuts
* ride height calculations
* shock travel setup
* spring stacker charts
Perfect for:
* rock crawlers
* Ultra4 cars
* race bouncers
* Jeeps
* custom tube chassis builds
Formula(s) to get Stacked Spring Rate Chart Number:
1. Spring Length - Compressed Length = X
2. X times Spring Rate = Y
3. Y divided by Inches Collapsed at Ride Height

Timestamps:
Calculating the correct spring rate for your coilovers is one of the most daunting tasks for any builder, but it doesnt have to be. In this masterclass, the Wide Open Design team reveals a failsafe method to determine your rates without ever needing a set of expensive scales [00:51]. We start by installing a single mock-up spring (usually a 150lb rate) to measure the actual weight the shock is supporting [05:56]. By measuring how much that spring compresses under the vehicles weight [07:17], we can calculate the exact poundage—eliminating the need to worry about complex mounting angles or trailing arm leverage [08:02]. We then show you how to use our Spring Stacker Chart to select the perfect secondary spring to achieve your desired ride height and dual-rate performance [09:00]. Stop guessing and start engineering your suspension for the trail.
