Yeah pretty much what i thought looks discoloured prob due to heat, if the clutch has been treated hard it wasn't from me (previous owner) only strange thing I noticed was there would be a shudder pretty much every time I take off from a standstill no matter how I would let the clutch out be it riding it or gentle throttle or rev n dump always a momentary shudder I just assumed it was in the diff. Anyways thanks for the replies guys heads at the machine shop so I'll give it to him to machine the surface and convince the misses a nismo Coppermix is the only solution to this problem.

The heat has probably just altered the material on the clutch plate a bit so it doesnt grip quite as well. No big deal seen as you know where to go from here. Consider an NPC clutch and flywheel as they are both great products. The clutch you have now looks like its only a 9.5", you can go NPC 10" which means it will handle the power and still be relatively soft pedal feel.

Had this car had the clutch replaced not too long ago?

Flywheel appears to have fresh grinding marks on the area not exposed to the driven plate.

The marks look like the wheel wasn't machined on a lathe, it was done of a surface grinder and I haven't seen a wheel done by that method for a long time.

May explain your jumpy clutch.

My clutch is never done on a lathe, and I dont know anyone who does this with a lathe

Forget the name of the machine mine is done with but you end up with what look like big swirls through it but I have never had a clutch problem. It's the proper machine for doing it

Well apparently rebuilt box and new clutch about a year before I bought it. I've been lucky to have put 5k kms on it But who really knows. I thought buying a nice clean stock car would mean leaving it alone so I can play with the other car but all it's done is make he garage look even busier. Thanks for the replys guys.

Here's a pic of plate and clutch for interests sakepost-3493-14020214248945_thumb.jpgpost-3493-14020214497259_thumb.jpg

      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
