The Cuscos Zero 2 and Tein Wagons cannot be compared. Teins flex are awesome, superstreet is ok (howevever id still go D2s since superstreets dont have a lower adjustment and are twin tube (note monotube is better)). Unfortunantly they dont make Flex and Superstreet for the ZZE12X corolla (they do have superstreet for the US model but not sure if it fits). Cuscos Zero 2 are superior to Tein Wagons and superstreets; however are on par with Tein flex. Given whats avaialble for the Rolla Id i'd buy steet coilovers in the following order: Cusco Zero 2 --> D2 Street --> Cusco Zero 1 ---> Tein GT Wagon --> Tein Super Wagon Some1 else on here had DMS coilovers, they don't allow too much of a drop (i think 50mm) but they are an awesome coilover but pricy (think 3000 dollars or so). Make sure you comparing the products correctly cuz they make variations of every brand. There are also other coilover you can get for the rolla, but i only know specifics of the above. Cusco Zero 2 --> D2 Street --> Cusco Zero 1 ---> Tein GT Wagon --> Tein Super Wagon which one is the most comfortable and the best handling to drive? TRD you cant have both...the best handling wont be the most comfortable.. northy, if it is looking to get balance between handling and comfort, which one would be good? my big concern is the suspension can't be too bumpy(can take exceptional sporty) and only need to drop down 35mm from stock height at this stage. my front bumper is too low. it is main for daily drive. i am using lovell 55mm super low at this stage and its make too bumpy. Cusco Zero 2 --> D2 Street --> Cusco Zero 1 ---> Tein GT Wagon --> Tein Super Wagon or Koni shock with 30mm H-R spring? TRD
