+1 on the pic, but I doubt it will get rid of the 4x4 look at all.

I need to at least give props to OP for trying out the ZSP springs, that could be useful info for others!!!

Nope, a 330. And the front is still way too high.



Also, I do feel a slight improvement in handling after I drove the car more around my normal routes. These springs will get me by until a proper spring and shock package is developed for the xi.

Did you give it a chance to settle after install (few days)?

If they were new, they'll drop some more after settleing in.

They are used - purchased from a guy on this board. I don't think they will settle much. I'm going to remeasure everything to see if they dropped anymore. I do notice a difference in handling. Especially today when I drove it to work on the usual on/off ramps.

After more driving I am very happy with the ZSP springs. The car feels much "sportier". The highway floating feeling is gone and the car doesn't feel like a boat on on and off ramps. Also I measured the drop again and there are solid 1/2 drop all around the car. As you can see from the picture above I think it took care of the 4x4 look and gave it a normal looking ride height. So for the price I would do it again.

nice i thought about getting them i hear its only .8" drop. Good to know this info though. I' i'm considering eibachs as it's less aggressive for a pot hole city

Won't using zsp springs with the xi shocks still will accelerate life of the xi shocks... at first I was considering get the Eibach Pro with stock shocks but if the zsp spring will work fine with zsp springs I rather do that... plus on getting the lowering perch when they're in stock again (10mm-15mm lowering)..

using any aftermarket springs (including the ZSP ones) with the oem non zsp shocks will kill the life of the struts which is why if you don't have ZSP you really should replace your struts with the springs or just get coilovers.... my oem struts are just about blown and the springs have about 20k miles on um.

Thanks for the advice.. I dont plan on doing anything to the suspension till.. hopefully they're more suspension options for the XI in the future..

maybe but I kinda doubt it... there really isn't much more you can do. You can get koni's or blisteins to match with the springs but they still are made to work with each other 100%.

If you want a drop, even springs will run you like $200 + $200 install (if you can't do it yourself) and you'll have to replace you struts about a year or two after so that'd be like $600 + another $200 install. So now after a year or two you're up to $1200 in stuff and coulda had the H&R's installed for that price or upgraded to the KWV1's for the xi for another $200 (these are recommended since they won't rust out on you if you live in a place that gets rain or snow like the H&R's have been prone to do). The springs (which I have) are good if your on a budget and don't care to think down the road but the smart choice if you plan to keep your car for a while is to just pony up for the coils, when you're done, get um uninstalled and you'll get 60-80% of your investment back.
