This chassis started it all for us! Feal Suspension founder/engineer/top ranked Formula Drift Pro 1 driver Odi Bakchis piloted an S13 in Pro-Am where he secured multiple victories and obtained his Formula Drift pro license in just 1 season. Countless hours of testing valving formulas, spring rates, and stroke/shock body dimensions have gone into this kit to create the best coilover solution on the market.
Feal 44x lines are used worldwide for top level Drifting (Formula Drift, Drift Masters GP, Russian Drift Series, etc.), Time Attack (NASA, SCCA, GTA, Gridlife, etc.), and Drag Racing, and we have the technical knowledge and expertise to build a kit to meet virtually any customer’s exact needs.
We know how popular engine swaps are so we offer multiple configurations to meet your setup needs. KA, SR, CA, and Aluminum LS motors spec kits come with an 8k front spring rate, and heavier motors like JZ, RB, or Iron Block V8s spec kits include 12k front springs with increased valving damping to match.
Each shock is designed with expertise from our success in many top-level international motorsports and through years of experience tuning various shock brands. We at Feal Suspension strongly believe that our coilovers have an edge on shock design that gives you confidence and a competitive advantage where needed most.
441 - Damping adjustability that adjusts Rebound and Compression in one knob. Very easy to tune vehicle firmness, dive, and roll.
442 - Separate damping adjustability for Rebound and Compression. Rebound adjustability does not change compression force so that you can fine tune the roll and rate of weight transfer. The huge range of compression adjustability is independent of rebound force. The compression adjustability will allow you to adjust for more or less traction and more or less suspension movement on the compression stroke.
443 - All of the above plus separate damping adjustability for High Speed Compression, Low Speed Compression, and Rebound. Low speed compression damping adjustability allows you to fine tune chassis movement on the compression stroke over round bumps and/or throttle and braking inputs. High speed compression adjustability allows you to fine tune bottoming resistance and wheel movement on the compression stroke over rumble strips and square edge bumps.
