949 Racing Xida-S - Initial Impressions

finally got my xida-s and installed them today! also removed the stock strut bar, removed the front sway bar and rear end links. will be installing the new bar and full set of supermiata endlinks once the links arrive and i figure out what to do with the excess material on the sway bar bushings. also, when i removed the stock bilsteins i noticed a kind of pink looking powder coming out of it. turns out my bump stops had basically exploded

these feel quite good so far, just need to play with the damping settings a bit. rates are currently 700/450 and set to full soft, theyre way smoother than my 10/7k tein flex.

unhappy about my height range at the moment. posted a message on the xida thread at mnet, hopefully i'll get an answer soon. my front and rear pinch weld heights are both 4.75" (with 23.2 tires, so this equates to about 4.6" according to emilio's standard 22.9" tire), fender heights were 12" Front and 12.5" Rear. one of the reasons i purchased these was because from all that i've been reading and confirmation with emilio, i was expecting to be in the range of 10.75-11.25 fender height or 3.75-4.25" at the pinch welds. it seemed like people were having trouble even getting to 12 at all. sounds like they're all around the height range i'd like to be but want to be in the range that i got :(

with the fronts at 12", if i lower the perch anymore, at full droop the springs will be completely unseated and even at this height they will rattle

the rears compress the secondary springs a bit at full droop and i can adjust these a little lower, but if i go lower than 11.75", the perch looks to be dangerously close to the axle. if this is normal, i think that my desired height can be reached in the rear, but i wouldn't lower the rear any further until i can figure out why my front is so high. reverse rake doesn't seem like a good idea.


how should i go about figuring out what damping setting i need to be at? one method i believe i read was to start full soft all around, drive it around and increase all settings by one until i arrive at a setting that feels good, but what if the front and rear are not to be the same setting? also, will the both fronts and both rears always be the same as each other, or would it be possible to have all 4 corners set differently?

one of the rear shocks has 13 clicks, the other 3 corners have 12 o_O

aside from that, they're really beautiful, can't wait to get them dialed in :D

they came with eibachs in front and hypercos in the rear. too many colors on the front pair lol.






wish it were a little lower :(



i can't help but wonder if my height is an isolated case since i was banking on being lower than this. at least for the front, the lowest i can go is 12" before the springs completely unseat at full droop and that just doesn't seem right for everyones highest to be at 12 and my lowest is at 12 o_O emilio did say that it is ok for them to be unseated at full droop, but i mean that's kind of the reason i got the dual spring setup in the first place

some pretty charts from 949's website. still don't know what they mean

i'm a bit confused because part of the reason i ordered the Xida was because he stated in his thread that ideal handling for these coilovers was around 3.75" to 4.25" at the pinch welds, and now he's saying that im aiming to "slam it below what normally works best for handling." o_O

anyway, based on his response, i lowered the rear to 11.75" and the front to 11.25" and the front springs now will unseat at full droop. hopefully i never get that far while i'm actually driving, but it does still make me nervous so i'm considering longer secondary springs and maybe even the 5" rear springs to have the ability to lower it a little more. hope the 5" springs don't bind

i took the new height for a drive and the ride comfort was still impressive. the turn in wasn't as sharp as when the car was higher though. i should add that when i installed the coilovers, i uninstalled the front sway bar completely as well as the rear end links in preparation for the new RB sway and full set of supermiata endlinks so all of my driving impressions are without any sway bars connected at all.
