I know there has been writeups from a couple of other people about changing their Coilovers to the extended travel version. I just dropped mine off at Donahoe today, and I wanted to take a second to say that Donahoe's customer service is top notch. Those guys are extremely helpful and they stand behind their product 100%, and that's how you keep customers. I dropped them off for the extended travel conversion and at the same time they are going to replace both the coil springs because one of them had some powdercoating coming off and it was showing a little rust. Also they are going to upgrade both top plates because mine are the older ones and they are now using different top plates on all the newer coilovers. All of this plus recharging them and it only cost $40-$50 per coilover. They said I can pick them up tomorrow morning, so they were quick on the turnaround time as well. I can't say enough about the level of service from Donahoe Racing, which can be a rare thing these days.
