Tuner's voice :

We have spend a year of street and track testing. Our goal is to build a set of suspension which has street comfort for daily driver and also track capabilities at a reasonable price.

We have focused on the rebound on the suspension while maintaining high speed stability. Steering response is greatly improved. At full soft dampening, it rides much smoother over stock and absorbs well on bumps.

The reason why we are using higher rear springs rates is because the stock GR Corolla has a lot of "TURN IN" understeer , especially tight turns, it feels awful. With heavier rear spring rate, it helps to reduce understeer and increase back end rotation for better turn in while mid-corner is NEUTRAL.

Same suspension has been used on our Time Attack car for the 2024 season. We have been rated the fastest GR Corolla in the Pacific Northwest region.
