b'GTB TRACK-WARRIORGTE Offset, Decoupled 3-Link with Earnhardt Technologies Air Bump Stops Decoupled Means We Can Tune the Corner Exit Rear Grip & Corner Entry Rear Grip Separately! The Accel Link Sets Anti-Squat for Acceleration & the Decel Link Sets Pro-Squat for Braking. Decoupled 3-Links are the Highest Grip Rear Suspension Available. Anywhere. Period. But There are Different Methods of Controlling the Travel Each Direction.Our GT Version (Shown Here) Utilizes a Bump Stopped Monotube Shock Controlled Decel Link. This is a Great Method, with the Shock Valving Dampening Movement Both Ways. Our GT Version Also Utilizes a Canister with Tunable Rate Springs Inside on the Accel Side.SCCA & Trans Am Rules Dont Allow an Extra Shock. Before, We Used a Non-Shock, Poly Bushing Versions Like This.They Work Great!Not Quite as Good as the Shock Version, but Very Well. The Only Drawback is the Poly Bushings Wear Out & When They Do, They Split & Pop Out. Not Good. We Had to Change Them Often. Using Multiple Poly Bushings Together (Shown Here) Spread the Load & Lengthened their Life, But They Still Need to Be Replaced with Maintenance. Recently, Earnhardt Technologies Group (ETG) Developed Air Spring Bump Stops That We Utilize Instead of Poly Bushings. Like Poly Bushings, the Air Bump Stops Have a Similar Very Progressive Spring Rate Curve to Them. This is Perfect for Our Needs, As We Want the Initial Movement Quick, Then to Slow Down & Soft Stop.The Earnhardt Technologies Air Bump Stops Have Several Advantages Over the Poly Bushings. #1, They Dont Split & Pop Out!Second, We can Tune the Rate WITHOUT Taking Them Off, by Changing the Air Pressure in Them. The Chart Shown to the Right, Shows Rate Changes with PSI Changes. The Air Bumps Come in 4 Travel Versions from 1/2" to 2. They Fit Onto the ETG Bump Stick & Bolt Into the Chassis,Just Like a Shock Would. The Bump Stick Doesnt have Any Internals. It is Just a Well Designed Carrier of the Air Bump Stop. You Can See Where it Goes on the Previous Page.For the Accel Link, We Utilize ETGs 2 Travel Pull Bar. Same Technology & Progressive Spring Rate as the Air Bump Stops. Both Have Travel Indicators.110'
