The coilovers are QA1s. I think Carrera bought them out of vice versa. I think the model is Proma Star. I havn't bought the springs yet as I'm waiting to get the car all together so I can weigh it.
Here's my shock. Since I bought mine they've introduced a double-adjustable one too, rebound and compression.

For the money it is a very good shock, but if you really want to spend some cash, try Ohlins.
