john kosmatka Posted July 3, 2005 Share Posted July 3, 2005 Hey guys, In my ground control 280z kit, they say that the front setups need a washer on top of the upper spring perch, but not in the back, but they give you four washers, do you use two on each side? Also are bump stops needed when running coilovers? Ive looked at a few setups and it looks like they didnt run any bumpstops, is this reccomended? Any help would be appreciated, Thanks, John Quote Link to comment Share on other sites More sharing options...
Here comes trouble Posted July 3, 2005 Share Posted July 3, 2005 Bump stops are a good insurance depending on your pounds to the inch compression weight of coilovers and length of coilovers..ie 160# , 10 inch coilovers could use a bumpstop. Use one washer on each side of front and send the 2 extra to me. Quote Link to comment Share on other sites More sharing options...
buZy Posted July 3, 2005 Share Posted July 3, 2005 With your spring backed off or removed check the compression of your strut. If the strut housing gland nut hits the spring seat, you need bumpstop. If it doesnt hit the spring seat and bottoms in the cartridge, you need a bumpstop to prevent internal strut damage. Check suspension travel and cut your stop length to about the last inch of motion. Every case is different, but that is what I did and it worked out fine. Quote Link to comment Share on other sites More sharing options...
john kosmatka Posted July 3, 2005 Author Share Posted July 3, 2005 Thanks for the help buZy, so you can just pic up any generic bumpstop at an autoparts store? and cut it to fit your application? So anybody know for sure what to do with those two other washers? Thanks again, John Quote Link to comment Share on other sites More sharing options...
buZy Posted July 3, 2005 Share Posted July 3, 2005 Hey John, Ground Control sells generic stops in few different sizes. That is what I used actually and cut them to fit. Quote Link to comment Share on other sites More sharing options...

JMortensen Posted July 3, 2005 Share Posted July 3, 2005 The washers are the new perches for the threaded collars. I used all 4 on mine. The only way you could not use one is if you used the original weld bead after cutting the original perch off. Energy Suspension sells bumpstops too. You can get them from http://www.suspension.com Quote Link to comment Share on other sites More sharing options...
john kosmatka Posted July 4, 2005 Author Share Posted July 4, 2005 Not quite the washers Im talking about, I already have the new perches for the threaded collars welded on to the strut housing. But in the little instruction sheet it shows that a washer goes on the top spring seat. It says it only uses them on the front, but with the 4 washers in the kit im not sure if you use two on each side or if the other two are just spares.

JMortensen Posted July 4, 2005 Share Posted July 4, 2005 Hmm. I have GC camber plates and they have a flat needle bearing assy on top of the hat. That bearing has a thin washer which sits in the aluminum hat, then the bearing rides on that, then a thicker washer that sits on top of the bearing, then that thicker washer sits on the bottom of the camber plate. I don't know what the non camber plate version looks like. Hope that makes sense... Quote Link to comment Share on other sites More sharing options...
Here comes trouble Posted July 4, 2005 Share Posted July 4, 2005 Do as the instructions imply (and send the 2 extra washers to me).. The washers are used as a flat bushing on top of the coil overs when the steering wheel is moved and/or the axle spindles turn. Quote Link to comment Share on other sites More sharing options...
john kosmatka Posted July 4, 2005 Author Share Posted July 4, 2005 cool thanks, so the other too are kinda like spares if they wear out? Quote Link to comment Share on other sites More sharing options...
