A full set of R34 GTS-T HKS Hipermax II coilovers,

Spring Rates: F:7 / R:5

Condition: Used, no leaks or knocks, good working condition, came out of a R34 GTS-T (unsure what other models they will fit)

Located in Adelaide, inspection welcome.

$900

About Them:

The HKS Hipermax II coilover kits provide the ultimate in suspension tuning with 30-way dampening, threaded dual-chambered shock assemblies and perches for height adjustment. The design of the upper Pillowball mounts delivers improved steering response and tempered springs are included.

Tuning your vehicle’s suspension is one of the easiest ways to instantly improve overall performance. The HKS Hipermax II suspension, which offers both ride height and shock dampening adjustments, provides improved handling characteristics while maintaining your vehicle’s ride comfort. Ride height is adjusted by simply rotating the 60mm spring retainer perches around the chromed steel shock body. The dual interlocking spring retainer perches prevent spring movement and unwanted ride height changes. Dampening can be adjusted at 30 settings (20 on some applications) to deliver the desired shock compression and rebound stiffness for custom tailored driving characteristics. The included anodized aluminium upper Pillowball mounts retain spring placement and improve steering response and maintains suspension geometry. Additionally, some applications offer camber adjustments on the upper Pillowball mounts. Each HKS Hipermax II suspension system comes with all the needed adjustment wrenches, stiffness adjusting knobs, and miscellaneous hardware for complete installation and tuning.

Features:

* Chromed Steel shock body assembly with precision-cut threads

* Shortened cylinder body and piston stroke

* Single tube structure with large free piston

* Single tube structure with low-pressure nitrogen gas

* Dual oil and gas chambers

* Anodized aluminium Pillowball upper mounts

* Anodized aluminium spring perches

* Dual rate progressive coil springs

* Fully rebuildable

More Information:

- Single tube structure with inside base valve delivers sport performance and comfort ride. Damping force of HIPERMAX II is adjustable by 30 steps for various situations.

- HKS developed special oil for the damper series. The viscosity is not affected by oil temperature. Thus, the damper keeps on performing during continuous hard driving.

- Newly designed piston delivers quick response.

- The oil gallery for the piston was newly designed for ideal oil flow. As the valve response is quick, it achieves stable damping force from low piston speed.

- New designed oil gallery of base valve controls inside pressure for road holding at low piston speed.

- The structure of the oil gallery in the base valve was improved. Diameter of the cavity is optimised to ensure proper inside oil pressure to prevent cavitation. Due to the new design, it can still be a comfortable ride with high road holding performance even at low damper stroke speed.

- Free Piston divides oil and gas area. Oil and low pressure gas are completely divided by free piston. Thus, response of damping force is quick and stable.

- Low pressure gas area in the bottom part of the cylinder eliminates uncomfortable bumpy ride at low car speed.

Apologies for digging up an old thread - but I'm trying to adjust a rear set of these and can't get my head around the setup :S

I had my car lowered at the shop, but I think they've gone too far on rear left as it's clunking around a bit. I wanted to raise the rear slightly (lengthen the shock) so it's not too short.

It states "Ride height is adjusted by simply rotating the 60mm spring retainer perches around the chromed steel shock body",however in my mind, this action would simply preload the spring?

I tried winding up the 60mm rings about 15mm but it didn't seem to have any affect on the clunking, so I assume it either preloaded the spring (not lengthen the shock as intended) or it's another issue?

Any help would be greatly appreciated!

Sounds like they are knocking. If so you need to get them rebuilt.

the way to adjust em is to unbolt the whole coilover

the bottom of the coil over should move

screw it up or down (the bottom of the coilover) depends what u wanna do raise or lower and ur done

      In B4 "Not a Skyline"...

      By Rezz · Posted

      You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.

      Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.

      In B4 "Not a Skyline"...

      By Rezz · Posted

      2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers.

      Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
