ihiryu Posted January 30, 2013 Share Posted January 30, 2013 Okay, so this is pertaining to a S30. I was doing some thinking last night, but a lot of people are running S13 coilovers (which I'm hoping to do as well). So I was thinking what if we were able to use the 240sx hub since we are using the lower mount on the coilover setup. I took a look at a few pictures last night comparing the hubs and how they set on their respective cars. The biggest issue is where the tie rod ends connect. They are on opposite sides. If we were to swap the 240sx hubs on our car, then we would have to flip them around (so left on right, and right on left). However, the issue with that is the brake caliper will be placed on the front rather the rear. The major pros that I can see to this (if it all works that is), would be the ease of doing a five lug swap (in the front) and we would be able to use a plethora of brake kits (z32, z33, even evo and sti brembo setups). I think that the issues really come down to the steering arms, I don't know what the size of our tie rods are, or even the lengths that would be needed in doing this swap. I don't know if we'd be able to use our stock inner with a S13 outer (also if we can use the S13 outers that means we can get longer/adjustable units). Does anyone else see any issues that we may encounter by doing this?

So we would use the S30 control arm, the complete S13 spindle (on opposing sides), and S13 coilovers. This would eliminate the need to do any cutting and welding (sans the coilover mount). I think the biggest issue is going to lie with the tie rod ends, but I don't know what else could be. Hopefully someone can chime in!

R3VO 3VOM Posted January 30, 2013 Share Posted January 30, 2013 Now I have sectioned struts and 4x4 calipers, so I wouldn't know too much, but wont this mod raise the ride height of the car really high? Because on my 240sx the strut mount is like on the top of the spindle whereas on the megan and such weld on coilover tubes to fit s13 coils into an s30 weld onto the bottom of the s30 hub. I suppose you could argue that the tube gives height so the mounts would be near equal height. But my question is why reinvent the wheel? While I understand your idea for brake options and 5 lug, some of them get pricey (Evo caliper swaps go for near $800 with rotors). While there are options out there more readily for the S13, there are also options out there for the S30. I've seen 5 lug swaps (Z31 hubs I believe?) and there are plenty of brake options out there. We must remember that Z32 brakes on a S13 are way overkill (I think people do those swaps for bragging rights/ they like the look/ both. I have buddies with heavily tracked S13's and they say that Q45 calipers (2 piston floating like the stock S13 caliper only larger pistons) are more than enough with proper pads and rotors; whereas the Z32 is 4 piston) and it weighs more than the z. I think that there are plenty of options out there, even for heavy track driving, for comparable price that fit the stock s30 spindle assembly no problem.

johnc Posted January 30, 2013 Share Posted January 30, 2013 Swapping spindles from side-to-side is generally a bad idea. You'll probabyl have huge steering issues and create a lot of bump steer. Read up on Ackerman and Bump Steer. Quote Link to comment Share on other sites More sharing options...
ihiryu Posted January 30, 2013 Author Share Posted January 30, 2013 Both of you guys raise very good points, I'm totally glad I didn't just on this without thinking ha ha. I didn't even think about the height difference from how the spindle on the strut, how that would raise it up a good bit. I won't proceed with this, but I WILL look into a few other things, it just goes to show, the more I know, the more I don't know ha ha.

ComicArtist Posted February 2, 2013 Share Posted February 2, 2013 It's been done before. Seems easy, but the aforementioned geometry issues come into play. Also there is a problem with the angle of the balljoint on the lca going to the s13 spindle. It jus doesn't really work. Quote Link to comment Share on other sites More sharing options...
ihiryu Posted February 3, 2013 Author Share Posted February 3, 2013 I haven;t heard of it, link?? Did you ever do the DC2 coils?? Quote Link to comment Share on other sites More sharing options...
