It is a S15 Silvia with RB25DET and R33 gearbox. 8kg fr 6 kg r on softest setting. It has camber and toe arms and it doesn't have much camber.

It holds up if I floor it from a rolling start on a motorway in 2nd, but it will lose traction on back roads or where tarmac is not as good

decent setup then.

im surprised those tyres don't hook up better...

I used to have those coilovers in that spec and I found that running the rears at about 10-25% damping was the best. Something about fully soft wasn't goood and I remember the traction not being as good. THat was in an R33 though and only 240rwkw...

There is never going to be middle ground between Skylines and later Evos . There is no perfect performance car either . People ask me which of mine is better and I just say they're different . Much o

The manufacturers loved it because they never made money out of the special production cars anyway . Not so good for petrol heads . It allowed the change to Bogun spec-tater racing because beer swill

Mick, yes the supra will, but then the thrill being its a different car and right up there at the performance forefront, not to mention the easy power u can get outa them and the GT feel, cockpit etc, a monster that actually looks nice /sporty

Kasko I was lucky, checked ebay and a set came up at one of the skyline wreckers-think I got away with $450- a steal.. Just test the dampers by removing tops, compressing by hand and checking rebound. And f$&k those coilovers off..

Yep dunno if the SK Bilstein Whiteline kits are still around , I think he said some of the springs may not be available .

However , the SK re rated Bilsteins are and that is a good start . He said you can do a coil over conversion on them (threaded sleeves on circlips) and use small diameter springs in the right rate . Really all the bling lookin tops with spherical bearings do is give you grief on a Skyline .

Also he organised some years back an adjustable Silvia stut top that solves some of the lack of compression travel issues .

If genuinely interested I may be able to contact him , cheers A .

It's not hard to contact Gary. He responds to PMs on here. I bought a set of his tricked out dampers from him only a few months ago.

I did have some trouble with springs on an R32 GTSt. The normal low Kings springs seem to be all wrong, about 35mm too low, even when the Bilsteins' perches were set on the highest groove. So I ended up with GTR springs, which is not a problem at all, as they are a higher rate than the GTSt springs anyway - right in the middle of the happy range of about 5 kg/mm.

You can of course get Eibach springs, and the coilover conversion (which costs a fair bit of money) is of course still an option.

When I bought mine originally, I had the same issue.

On the "std" (middle) setting, the whiteline lowered springs were about 30mm too low. Even on the highest circlip groove, the car still sat too low (10-15mm from memory). I ended up having more grooves machined into the shock (as recommended by SK). Car now (at its highest setting) sitts about 355mm eyebrow height on all corners but drivers front. Drivers front sits at 350mm.

Contemplating chucking stock springs back onto the bilsteins and running them at std height...

That was with Whiteline springs? Gary has recently said to me that he'd not heard of anyone else having this problem with either type of spring. The Kings springs are supposed to be copied from the original Whiteline design (according to Gary, who designed the Whiteline spring). I had wondered if Kings had started stuffing up the specs on the R32 springs, but maybe there has been a problem of bigger proportions.

I have previously driven a well set up soarer in anger and loved the setup, bilsteins and 'stock height' King Springs.

Just a thought.

True to his name this thread is on track as a trip to whitecastle.

Yup...with the whiteline springs that came in the kit.

IIRC I had a PM from gary where he explained words to the effect of..."On the std (yellow) cir clip groove, std springs will sit at OEM height (~360mm eyebrow height or there a bouts)."

The whiteline springs being the lowered type (~25mm lower than std), would make the car sit 25mm lower than OEM height on the std cir clip groove.

Hence, you would need to have a cir clip machined 25mm offset to the std. All of this is not taking into account any spring sag...

Nah that can't be right. That ~350mm height is the best lowered height. The standard height is somewhat higher than that. Something like ~370mm.

Cant remember what the OEM eyebrow height is, but I know to pass regency its 360mm. 370 probably is about right now that I think about it!

Last time I asked Gary he said the Evo spec Bilsteins from some 8s and 9s are pretty good valving wise . A certain 7 is doing well with them though you do get side load problems if you use concentric lower spring seats on the front ones - which would include pretty coilovers .

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
