another s13 coilover question


Recommended Posts

Now I know this topic has been talked about to death and I been searching but for the rear perches, instead of using the zcc or the stance/megan perches, would you be able to use these from megan

I mean it is a pair of front perch in this case you would need 4 front perches for the s13 to s30 coilover setup. Thanks in advance!

If they were made out of steel, you technically could. 

 

I priced it out in the past, but it wasn't worth it from what I recall.

 

You would have to notch the bottom of the tube, cut off the brackets possible turn down the flare at the bottom. Not to mention you still need to weld the, tube onto your spindles.

 

On top of that you still need to get the camber plates for the top of the struts.

 

Mckinney has the whole conversion kit for 290$ for the 4 tubes with the tops. That's pretty hard to beat.

Thanks, I guess I better check to see if my konis that came with car are blown or still good. If there good ill be going the sectioned ground control strut way. If they are blown then I was thinking of just going the s13 route. Wish the weather would warm up so I could resume working on her.

Not trying to insult you, but did they come on the car, or with the car?

 

If they came on the car, you won't be able to section them...if the previous owner sold you shorter struts to use for sectioning, disregard the comment above.

 

Take note, mckinney says that their coilovers are valved differently then the S13 coilovers from megan. I personally think the 8k F, 6k R that they come with may be too much for the Z that's around 500lb/inch front and 350lb/inch rear. When I spoke with T3, they said a lot of their customers are happy with 185-200lb/in front and 200-225lb/in rear with ground controls. That's around 4kg/mm.

I used those on my old 280ZX, I just bought a set of S13 coilovers and cut off the bracketry. The rears are a direct bolt on so no threaded tubes were needed there. You can see my build here: http://forums.hybridz.org/topic/94002-how-to-install-s13-coilovers-on-280zx-and-poly-bushings/

awesome feedback you guys, one more question. Do I really have to tig weld the tubes to the hub? I been rocking out with my gas mig set up, can I just use that?

 

No, TIG wouldn't be necessary. This summer I compete in Targa Newfoundland rally in an AE86 Corolla (because the Evo we built blew its motor first stage, but that's another story. Anyways, the AE86 front suspension is pretty much identical in layout to the S130 and uses coilovers built the same way. On day three we came around square left way too hot and flew up and over a curb and nearly into a front porch. After completing the stage and driving back through town we discovered the spindle to tube weld had entirely let go. It was was "professionally" TIG welded by a fairly reputable shop, and though it looked pretty, there was zero penetration into the cast spindle. In fact as soon as the strut was on unbolted, the spindle fell off with no sign of ever being welded. I then pulled the other side since I had no faith it after that. We found a shop willing to let us in after 9 and perform our emergency repairs. Fortunately they were equipped with an ancient but ginormous miller MIG and an oxy torch. I turned the beastly MIG up to its highest amperage and wire speed, heated the spindle to a cherry red and went to town concentrating the heat on the cast iron. Unfortunately there was just enough wire to weld up the broken side. Of course this was a late night quick and dirty rally repair. In addition to the preheating, there's a few more precautions to take welding cast (keep in mind I am not all a professional, so take my word with a grain of salt, the following information is just being parroted from the internet): Cast iron is high carbon, so your filler material should be similar. Stainless wire will have a higher carbon content than mild so it will do in a pinch. There are filler wires out there meant for cast iron but you'll probably have to order them online. Second, in addition to preheating, cast welds should be stress relieved afterwards. To do this you want to cool them very slowly. This can be done by putting them in a hot oven or BBQ and gradually lowering the temp over a few hours, or burying the piece in hot sand. As well you can lightly peen the weld immediately after welding. This involves tapping the bead lightly with a ball been hammer.

 

Anyways, back to our semi-relevant Targa story. Fortunately both sides held up, because the next day was notoriously punishing stage. It's not all that apparent in the video, but aside from the straight fast roads, the pavement is rough and undulates like you wouldn't believe. It felt like the tire spent as much time in the air as it did on the ground as it pitched side to side:

The S30 is typically set up with 10% stiffer in the rear and more around 200~300 lb/in. S13 coilovers are more like 33% stiffer in the front. Not to mention they are way stiffer all around. IMHO it is not a good solution unless you account for a revalving of the struts. AZC has a proper solution for that sort of setup.

Weird that the race is allowed.  People and their property so close to the road.  I thought that these kinds of races only happened in Third Worldish places like Mexico.

 

Where's the video of the trip over the curb?

 

 

There's certainly a fair bit of controversy about the potential for injury and property damage, and there has been cases of both in the past. Keep in mind Newfoundland is an island the size of Great Britain, but with a population of only half an million, and that's mostly concentrated on once peninsula on the south-east tip of the island. The small fishing villages where most of the rally stages take place look somewhat third world. Unfortunately 2 of the city stages, Gander and Marystown have pulled out of the rally. 

 

That's the only video we've got uploaded, but stay tuned to our facebook page (www.facebook.com/targaevo80) for more.  

 

In the meant time, here's a Subaru hitting a house:
