The fill port is closed, and we are good to go!
Feal uses the ultra high-quality Swift springs for their coilovers. Swift uses superior metallurgy using their proprietary HS5.TW steel and special techniques for spring winding to makes springs with very consistent rates, long life, and minimal weight. We feel that Swift springs are some of the best on the market.
For the B13, we opted to run 6kg front springs and 5kg rear. This equates to 336 in/lb and 280 in/lb. This is an increase from the 300 in/lb and 200 in/lbs that we had been running and a huge increase from the stock 123 in/lb and 112 in/lbs springs.
We didn't want to go too stiff because the B13 doesn't have good chassis stiffness and a stiff spring will not ride well. The rear suspension also binds, and we didn't want too high of a rear rate to stack on top of the rear suspensions natural tendency to bind.
The spring seats and the lock ring for the strut mounts go on next. This wave spring prevents the strut mounts from coming loose when the steering is turned.
The spring seats and the spring thrust bearing are in place. The spring thrust bearings allow the spring to twist freely as it compresses. This helps take side load off of the shock shafts and reduces stiction. The spring bearings can improve ride and traction.
The bump stops and dust boots are installed, the top hats are bolted in place and our rear Feal coilovers are assembled!
