Duncan,,,If I ever catch you with a jack under a brake disc your gonna look pretty funny walking around with your torque wrench up ya bum.

Neil.

i was just going to say the same thing... then i remembered that time when duncan badly needed rear discs due to cracking... hmm. perhaps part of the lower arm is a more appropriate place to jack it up. :P

This is a picture of a Whiteline rear spring installed in an R34GTT.  Bit hard to tell from the angle but the top 2 coils are closer together than the other 5 coils.  This ensure that the spring is trapped at full droop (as in the picture).  Once the weight of the car is applied those 2 top coils collapse, sit on top of each other and the suspension movement (eg; compression over bumps) is then taken up by the remaining coils.

I will be very interested in how you find the handling and ride with your design of rear coil spring.

:P Cheers :D

Well I'll certainly keep you informed.

I can see what you are saying. Perhaps mine are not progressive rate springs?

The sucky thing is that because I've been driving around in a stock suspension R31 since I blew the engine on 11/9 anything will seem harder. It will probably take a week or 3 to be able to feel the difference between the old setup and this one.

Luckily I've got another complete set of king springs sitting there which can go in if these ones turn out bad. It's not too hard now I know what I'm doing and the bolts have been recently cracked making it a bit easier.

Here you can see the difference between the unladen stock front springs and the whitelines.. This is in an R32, but similar. I really liked the fact you didn't have to use spring compressors to get the whitelines back in, they are pretty much a "perfect" fit between the strut top and shock.

It's all fairly even. Looks like I've lowered it 2.5cm which is what I wanted. I've driven around a bit and it's firmer than before but not ridiculously so. It was still ok on the highway down the coast and some fairly bumpy roads down there.

I'm yet to get to the track but we will see when I do.

      So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here

      V37 Radiator removal

      So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.

      Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go

      OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
