E85/E86 FS: TC Kline D/A Coilovers for M Roadster/Coupe (Z4M)

Up for sale is a set of TC Kline D/As for Z4M. Spring rates are 450/500. I also have an extra pair of 500's for the front I'm throwing in. I put about 20-25k miles onto the suspension. Asking $1000 shipped or picked up in San Gabriel Valley

Few things to disclose:
-I'm the 2nd owner. The 1st owner lives in Boston so the tubes look weathered. I've had no problems with the suspension and I'm selling only because I sold my car.
-TCK D/A's make clunking noises up front. I hear it's because of the camber plates and it's completely normal.
-Front is D/A and rear is S/A
-Wrenches for height adjustment aren't included because previous owner lost them. They can be bought just about anywhere though.
-I noticed some clumps of gunk, probably dust and oil, stuck to the RSM of one of the rear shocks. I never noticed any problems with dampening and the shock behaves fine while off the car. It may need to be rebuilt soon though.
