“Took my 911 to Onyx to have the springs changed for a set of 20mm lowered Eibachs. Really friendly service, a nice clean unit and Ben kept me fully up to date on everything going on. Received the car back and although the job took a lot longer than they thought, they only charged me a bit more. Still a very good price compared to what independent Porsche garages wanted, and the Onyx facility looked a lot better than most of those too. Really pleased with how the car looks now, and the handing/ride hasn't been adversely affected - it really feels planted to the road now. While I was there I couldn't resist a run on the dyno, something I've not done for many years! Definitely a lot of fun, and nice to get a graph to put with the folder of my car, along with the videos of it on the rollers. If you have a performance car definitely do this if you are local. All in all, a great bunch of lads with a nice business/facility going, and I'm sure I'll be back at some point. Thanks!”
