I replaced my springs with Prodrives and the car is all back together and fine. Though I noticed that one of pistons for one of my rear struts falls with gravity. I'm suspicious that it's going bad. Should I replace it now? If so, can I just replace the rears and with what brand? So here's a few tips for anybody changing springs for the first time, like I just did. 1. You'll need a huge breaker bar for the bolts. 2. And a 17mm deep socket for the rear strut nut. 3. Have a set of new struts ready to go in case your old ones are bad.
if it falls with gravity, it is bad, not going bad, but is bad. I have prodrive springs around the KYB AGX struts. I love the set up. I have them all set to 2 which is just a touch stiffer then stock. If you want to save the money and just want stock ride go witht eh kyb G2's
Yes you can replace just the rears. It's good practice to do both rear struts with oem or similar replacements (like the mentioned kyb gr2). Otherwise you'll end up with more dampening in the rear in combination with the lower spring rates in the rear compared to front (prodrive's rates)... usually not the most comfortable set-up. Come on Andrew. I know you are the type of person that's willing to spend a little more to get an upgrade. Check out the koni yellow inserts, kyb agx, and tokico d-spec for slightly upgraded yet affordable replacements for all 4 corners.
I have a fresh set of those sitting here at my desk for my coilover build. If you're into any form of motorsports with the car, call Lee Grimes at Koni direct, and without too much haggling, he'll likely sell you them for a good price, which will easily beat all the online retailers. And they don't gouge you on shipping either. Stuart.
Shock falling with gravity = lost gas charge. It's not dead but it's a sign it's on the way out. If you're seing oil too, then it's starting to get bad and should be replaced soon. It gets pretty obvious when they're actually, truely shot, car goes boing, boing, boing...:laugh: Just make plans for a future swap, that's all. My rears haven't had gas in them for over half a year. I've tried to worsen them through some rally-x and ice racing, but they're still not shot.:dunno: They ain't new, no, but they're not gone either. I was kind of expecting them to fail quicker. I plan to step to Koni Yellow inserts eventually towards spring/summer. You should start thinking about similar.
I had a front lose only its high speed dampening. Kind of weird. There was about an inch of freeplay in the shaft, but it still dampened on long travel. So it was jittery from road cracks, but didn't go boing boing.
not really. like back road runner said, it's just lost it's charge. it's not blown. and is, in fact, just going bad. it'll still do it's job fine.
