260DET Posted June 4, 2004 Share Posted June 4, 2004 These look promising, bump and rebound adjustable, anyone here using them and do you know GC's email address? http://sth2.com/Z-car/shocks.htm Quote Link to comment Share on other sites More sharing options...
JMortensen Posted June 4, 2004 Share Posted June 4, 2004 I don't think they have email. I tried the other day and ended up just calling them instead. Here's their website: http://www.ground-control.com/ Heard nothing but good things from the few people I know or talk to on the net who have used them.

rc's240z Posted June 5, 2004 Share Posted June 5, 2004 I know that Mark Belrose has those struts, and has not been too happy with GC. They seem to be very slow delivering what they promise in a timely manor. Quote Link to comment Share on other sites More sharing options...
tube80z Posted June 5, 2004 Share Posted June 5, 2004 I have the GC AD inserts and I'nm generally happy with them. The bump adjuster as three positions but it makes little difference which position you use. There's just not much adjustment. The rebound is very adjustable and this what I spend the most time messing with. Given your location I would recommend a set of Konis or similar with the digressive valving. I think being able to get parts in a timely manner would be very good. A local shock expert told me that Koni's would have been cheaper than what I paid for the AD inserts but provided no real details. So you have a lukewarm recommendation from me. They do work, there's little bump adjustment, and parts are hard to get if you need them. otherwise they do work well and will allow you to run proper spring rates for a racing Z.

JMortensen Posted June 5, 2004 Share Posted June 5, 2004 Can't both the Konis and the AD struts be disassembled and revalved? Might be a solution for Cary's problem anyway... Quote Link to comment Share on other sites More sharing options...
Guest zline Posted June 6, 2004 Share Posted June 6, 2004 It's a decent buy if you want to go that route..unless you can actually go there and get them...you wont like the turn around time at all. I would just get some of the Koni 8610 inserts...pretty much the same..nice and short stroke. less needed to get them to go. Quote Link to comment Share on other sites More sharing options...
260DET Posted June 7, 2004 Author Share Posted June 7, 2004 Have been looking at the Koni 2816 double adjustable series, the 8610 are single adjustable aren't they. I'm pretty sure that the car needs more bump on the front and getting double adjustables seems to make long term sense. Quote Link to comment Share on other sites More sharing options...

260DET Posted June 7, 2004 Author Share Posted June 7, 2004 Yeh the single adjustable Koni Sports are good, there is a set in the car now. But as the car keeps being developed, something that was once satisfactory sometimes becomes less so. Quote Link to comment Share on other sites More sharing options...

260DET Posted June 7, 2004 Author Share Posted June 7, 2004 Mr Koni is now making a 'budget' double adjustable insert, the 8611 series, just found them on the Koni North America site Summit Racing list them at US$225.39 each. I'm excited. Just have to work out a way to get at the bottom located bump adjusting screw without pulling the ball joint off. Quote Link to comment Share on other sites More sharing options...
