Rear LC springs on an X3? - Hyundai Performance Forums

Well I had a funny idea today while I was in class. I'm not sure if it's been posted before or not, but I'll shoot anyway.

What would happen if you put rear aftermarket springs from an LC on an X3 while staying with aftermarket X3 springs on the front? I figured spring rate might be higher because of the extra weight of the LC, so you'd get a stiffer ride in the back... I thought that this might help out in cornering (even if it would ride like $hit). Am I way off base with this or what? Just a thought I had, so share yours!

It would certainly lower it less and be stiffer, but I dont know if it would handle better without trying it. Stranger things have happened, and it would certainly help those of you with big stereos in the trunk.

Before I just go with some coilovers, I might try it out. I figured that the stiffer the springs in the rear and the tighter the suspension is back there, with softer springs up front (maybe a little extra weight for those X3's that have beta's in them), the better the cornering would be, especially while braking. Maybe it would dial in a little bit of oversteer? I don't know, I don't have any real life experience with suspension settings, but like you said, there's only one way to find out. I guess I'm just finding myself very interested in how to setup a car suspension wise.

Of course, I'm forgetting about the dampers... So my theory probably wouldn't work without a good set of those... :ermm:

Springs in general dont work without good dampers. Worry about those before springs.

Also, stiffer rear springs will not "tighten up" the rear if anything it'll loosen things up and make you more prone to oversteer. Beta swapped cars would want the heavier LC springs up front to deal with the weight, not the softer X3 springs. Overly stiff springs are not the Accent's downfall, its the fact that both ends are EXTREMELY softly sprung for any kind of performance handling. You're better off just saving for the coilovers.

Yeah that's what I figured. Right now I have some apex springs and KYB GR2's for the X3 that are waiting to go on the car, hopefully the front won't end up being too soft for the new motor. Quick question... Have you ever run into any coilovers for the X3 that come with adjustable camber plates? I know they make them for the LC but so far I've only seen hight adjustable and damper adjustable ones for the X3.

The Ksports for the LC fit the X3. If you havent picked up on it yet, the X3 and LC struts/springs share the same dimentions and the parts that fit one will fit either. A little bouncy on the street, but fantastic for racing/autocrossing.

GOOD TO KNOW. I knew that they would be interchangeable, I just figured the characteristics would be different. That really helps though, thanks!
