i fitted mine with the cup on top of the top hat, otherwise it wont seat right in the bush
i hated the fitment of mine, plus the top hats were too tall so i couldnt get the car low. i had custom shoter top hats machined, that let me go low, but the fitment was still shocking, and my wheels rubbed the coilover spring, so i soon flogged my rear coilovers on and just stuck with the fronts
spose it depends how low u wana go, what size wheels u run, and how much the bad fitment annoys u lol
