The rear is std. Adjustable spring platforms and spring tops were added to the shocks. The factory leaves (minus 1 leaf) are used to locate the differential.

Spring rates are yet to be decided. The front is running some springs that were lying around the factory and there are no coilover springs in the back yet. That is what shall be involved in the testing when it is rego'd.

Firstly the drilling of the lower control arm points. For street use the drilling would only mean enlarging the holes to accept the S13bolts. I however moved them out a fraction to create some more camber for track work. They are still on the same horizontal axis and the castor that the factory bolt holes have is till the same even though I have moved them out.

Secondly the FWD offset issue. I dont't see too many problems here as the silvia runs very close to this offset from the factory. As I am using pretty much a complete silvia front assembly I see no reason why it will be too bump steery to drive.

I shall keep you updated on how it drives once I begin some suspension testing. We can theorise all we want here on the net but on the track is where I will get my answers.

OK here goes. (Big Post)

Parts required. S13 lower control arm, spindle, brakes and outer tie rod ends. A set of S13 coil overs. You will also need another 1200 driver's side inner tie rod end and r31 radius rods.

Redrill your xmember to accept the s13 control arm bolts. The hole at the back of the xmember will be bigger than the front one because of the design of the bolts. When you bolt the arms in you will need to put a small spacer/washer to make them fit as they are slightly slimmer than a 1200 one.

Replace your 1200 passenger side inner tie rod end with your extra drivers side tie rod end. (This is so that the tie rods turn in the correct direction when used in conjunction with the s13 outer ends.) Your 1200 tie rods will need to have the outer thread machined to accept the s13 outer tie rod ends. There is your steering.

The shox will need the 1200 upper spring platform on them so that they can bolt into the top of the strut tower. So just change them with the s13 ones. Easy. The bottom of the shock will go onto your s13 spindle which is already in place.

Your r31 radius rods are next. The two bolts that come with the rods are 8mm from memory and are too small for the s13 control arm. So the holes on the radius rod will need to be drilled to accept 10mm bolts and obviously after doing this you will need to exchange the 8mm bolts for 10mm ones.

All of the above is thanks to Kev Rowley.

The rear coilovers are a little different and can only be done on sedans as their shock towers are straight up and down. Apparently all the others are angled. Corrcet me if I am wrong. Graham at Fulcrum told me that this will only work on cars with a straight up and down tower due tp the strength issue. He apparently did this same sort of setup with Murray Coote back in the 70's with a 120y. I am having to flare and cut a bit of the dust guard for the tower to make the rears fit.

Craig

Not sure about the size issue but even if my old one would work that would be nice.

Craig

Unfortunately not at the moment. id on't owna digital camera. i shall see if I can hunt up a mates one after chrissy.

Craig

As above. The old one is missing and the I can't upload a new one.

Craig

Damn it is fat!! I am using the S13 lower control arm assembly, hubs brakes, etc and S13 coil overs in the front end of my datsun 1200 sedan race car. I just put the front end back on the ground. It has extra track and thanks to drilling out the crossmember and moving the control arms out a bit more it is running a deg or two neg camber. It has so much extra track that I have to run fwd offset rims. It looks so FAT!

Also at the rear to fit my new coil overs in I am having to massage/cut away the outer skin that surrounds the rear shock tower to get the upper springs mounts and spring to fit in. It all looks unreal. Very excited and motivated to finish this little car off. Someone just buy my supercharged corolla for 6g now.

Craig

What size turbo are you running?

Craig

I am in Brisbane and may be interested if my supercharged corolla sells. Mind you I only want to spend $3500 so I can spend the rest on the racecar. Not thebesttime to be selling cars however.

Craig

Let me know if you guys are planning on catching up at Kev's and I shall drop in and say g'day as well.

Craig

P.s. Harry- You were right about my rear suspension setup. Chief technical officer knocked me back. I will be racing in street registered IP U2L at hillclimbs. You suck.
