Had my car on the hoist at home today as i dialed in my tomei cams when i was under the car putting radiator back in i was checking stuff out under the car and i noticed that 3 of the 4 dust boost have come off the bump stops. On closer inspection i noticed that there are markings on the bump stops it seems the shocks are coming in contact with them. once this happened it forced the dust boot all the way onto the shock jamming it.

I have the shocks on the standard height setting with king spings (not sure if they are low or super low or what not as they came with the car) Do you think i need to raise the car 1 notch or 2 notches on the circlips?

Cheers

did you cut the bumpstops in 1/2??

a mate and i have the same problem with the dust covers, they get a little tight around the shock and get pulled down and off the bump stops. i got in contact with gary and told me that it was just an isolated incident and the x amount of people who've bought this setup haven't had problems. apparently not.

i've zip tied the dust covers onto the bump stops and that seems to work a little, the bottom of the dust covers still gets caught on the top of the shocks, rather than around them. i think longer dust covers are required.

this is all of course on the recommended 345/355 height setting

Yea mine are cut more then in half, as in I cut more off so the bump stops are tiny (cut in accordance to SK picture). Im not sure if mine need to be longer, i almost think needs to be shorter! As the 3 of them were pushed all the way to the spring platforms. I was thinking about gluing the boots to the stops?

my car is more like 320mm i think so quite a bit lower.

320 mm is too low, bump stop contact is unavoidable at that height.

If you want to run it at that height (not advisable) then you will need to trim the dust cover. At the moment it is too long and being trapped on the shock shaft.

:D cheers :)

gary,

are the dust covers supposed to fit a little loosely around the shock? (i.e. the shock slides up and down within the dust cover)

or is it supposed to be relatively sealed? (i.e. the dust cover compresses and extends with the shock, whilst remaining held onto the bump stop and the top of the shock?)

i was thinking of lubricating the top are of the shock to allow the dust cover to slide around easily - but i think this will only accumulate more dirt and grime.

any ideas? it's not really doing its job if it keeps falling off.

Mine did the same, the original front dust covers I had were ok so I put them back on. The problem with mine is it stays on the bump stop and sometimes pulls it down a bit. The major problem is in the wet it makes an annoying noise as the rubber pops on and off the shock body.

Back from the dead to report same problem - I took the dust boots off as they were completely useless. Both front and rear are a poor fit and neither seal nor slide easily over the shock body. I am at correct height 345mm front 340mm rear.

The proper Bilstein covers or ones that can be zip-tied to bottom and top would be much much better.

I just replaced my shocks and springs and I bought the dust covers from Pedders. I think they were for their 4WD shocks or something but they were a pretty good fit. Long enough to go from the bump stop to over the shock near where the springs sit. It was kind of hard to get them over the shock but some vaseline did the job. I cable tied them as well and so far they have not moved and they had some play in it. Something to think about....

Just thought I'd add something to this thread, I have now installed a set of genuine Bilstein dust boots.

I bought the shocks from one company, but they couldn't supply the dust boots, which I thought was a bit strange. I later found out when I went to a workshop here in Adelaide called Manta Racing that only official suppliers of Bilstein shocks can supply the dust covers.

The boots I was supplied did require minor modification to fit over the original bump stops (they initially caused the bump stop to pop off of the support washer so I chopped the top of them off), but they are made out of a very tough compound that I doubt will fall appart like the originals.

As far as replacement bump stops go, I only found superpro's for the rear could be used & that dust cover they have is useless/too small so you'd ditch that bit of them.

I just ended up just trimming back the original cover/bumpstop assembly so I could fit the new ones over the top & am satisfied with the result.

    • Waaay ahead of ya....(evil laugh!!) Will show the fitment and spec details later when it isnt as rainy !
    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
