I have 05 SE7 that's been having suspension issues/faults for quite a long time and the dealer can't seem to fix it. I'll have it back a day or so and the faults will start again. Can anyone recommend a place where I can get a conversion kit like what is available for the RR? My warranty expired in November (the dealer is covering it since it hasn't been fixed) but if I continue having these issues later, the dealer will cost me a fortune. thanks in advance!
