Just bought some second hand HKS Hypermax D's.....Ride perfect...feel stiff but not too stiff...HOWEVER....My front Left seems to be knocking....more so when it reaches the TOP of its travel rather than the bottom.....You will be driving and especially over smallish bumps....u will hear it tapping against something whether its in the suspension or in the actual car im unsure of but was hoping soming on here would be of some assistance.....

Also....How do you adjust dampaning with these.....just the 19mm bold on the top or???? and its anti-clockwise is it not???

blown coilover, needs a rebuild. check out www.shockreco.com.au or give it back to the guy you bought it from.

usually damper is in the middle of top shaft, above bolt. You usually use a hex key to adjust and generally anti-clockwise = softer

it's not the 19mm bolt

u can post them to that place, i sent a pair up from melbourne, cost about $20 postage each way.

You have to do them in pairs, cost is approx $150 per corner to do a base reco, just hope the shafts aren't damaged because that will cost more. The place in qld are highly recommended, they usually take about 4 days for a base reco + postage time. Call them to get a quote.

Cheers,

TK

it may be a stuffed damper, but it may also be the pillowball tops.

i had these exact shocks, which made knocking noise just as you describe, it was not the shocks, it was just the alloy pillowball tops which wear out very quickly.

u can get them new for around $400 from what i have seen but i wouldnt bother as they will wear out quickly again.

clockwise is harder anti clockwise is softer, with a small hex key as merlinthehappypig has mentioned.

If it turns out to be the pillow ball, pm me as i have a pair of HKS pillow ball fronts that you could have for a lot less than 400.

Thet look like they are rebuildable by the way so if you can find replacement balls/carriers it will probably be cheaper again.

    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
