Unplugged Dual Rate Lowering Springs - Model Y

WHY CHOOSE UNPLUGGED PERFORMANCE DUAL RATE LINEAR LOWERING SPRINGS? Choosing UP dual rate linear springs means that you are able to enjoy a 15-30% softer spring rate around town than what is possible with low cost standard linear springs can provide with only one spring rate. After experiencing first hand, you’ll find that UP’s decision to take on the additional engineering work and production costs are well justified with UP dual rate linear springs because the technology allows for a softer ride than ever previously possible, all without giving up performance handling precision when it matters most. The primary spring rate (cruising around town over bumps and pot holes) is intentionally engineered to be as soft as possible for comfort. When the primary spring rate compresses under load (in spirited driving conditions) the second spring rate transitions in. The second spring rate is typically 30% more firm and acts to reduce body roll, increase grip and enhance precision. By comparison, when using lower cost single rate linear springs there is only one defined spring rate and therefore it cannot be made as soft because there is no second transition rate to firm up when needed. Alternatively, by comparison with lower cost progressive springs they allow a continuous range of spring rates but do so without the predictability, confidence and planted feeling of linear single spring rates. Performance drivers for decades have always chosen linear springs, this product is uniquely a dual linear rate engineered spring to allow high performance and high comfort. Heights: Mild:  approximate 1″ drop on non-performance Model Y and an approximate 0.25″ drop on the Model Y Performance Moderate: approximate 1.5″ drop on non-performance Model Y trims and an approximate .75″ drop on the Model Y Performance SPECIFICATIONS: Proven Dual Linear Rate spring technology allows for the best of both worlds. The car rides at noticeably softer spring rates around town. When sporty handling is desired, natural cornering g forces activate the spring’s 30% sportier secondary spring rate which reduces body roll and gives a noticeable difference in both feel and handling at the limit Physics have proven the benefits of range efficiency by lowering the center of gravity and reducing underbody air turbulence Produced in an engineering partnership with Formula 1 and 50+ consecutive Indy car winning spring supplier HYPERCO Designed, Engineered and Produced in America AERODYNAMICS: During our comprehensive aerodynamic study of Model 3, we tested the efficacy of our Dual Rate Linear Lowering Springs using CFD, and the results were dramatic.  After installation of the Moderate Version of our Dual Rate Linear Lowering Springs (1.5″ lower ride height), a decrease of 8.1% in total vehicle drag resulted, with a reduction of the total vehicle drag coefficient by 0.019 (factory ride height = 28.5″ baseline, measured at the center of the front fender). We expect similar results for the Model Y and will release the data when our analysis is complete.
