after all hassle and cost i went through very recently with these regretably gonna have to try and sell these as plan was to have my ek as 2nd car/toy (thus being able to have fairly raw and harsh car) but plans have changed this week

having to now keep my ek4 as my only/daily driven car, this suspension is wasted on daily car (uk roads) and is too harsh imho for daily driving so selling up, not even had chance to get on track with these :(


if you need to ask about these then not really for you but quantum are uk based company with office in japan so full support and servicing etc can be be done right here in u.k unlike many other coilover companies, quantum is simply up there with best suspension companies in the world, the u.k office primarily deals with motorsport while japan office deals with track/road suspension kits but as said u.k office provides full service etc

i bought these of member on here as needed bare components to send to quantum as could never afford new set (im not sure what set sells for new nowadays and wont bullshit people with this is how much they are new as irrelavant as no one would buy set new unless competing and/or very very well of but if you need to know ring quantum)

once received i had chat with owner of quantum and decided on what i wanted spec wise then sent of for full rebuild/service, i went for no changes as wasnt competing so didnt need more complex valving etc so full rebuild/service was carried out for me

so basically had like new set sent back to me in terms of internals/function etc, i managed to scuff top of 1 of the front shafts day i fitted them :nono: but has abolsute no affect on performance etc as due to where i did it only time that section enters chamber would be just before coilover bottomed out, they have covered no more than prob 900 miles

i will be providing a set of zeal springs with them but rate is unknown, stiff though and cant even take a guess at to what they are but ek9 they came of must have been tracked or roads in japan but must be pretty goodid imagine, ill also throw in oem set of ek9 top hats so you have full kit ready to bolt on and go, my plan was to order couple sets of custom springs and do some testing to find what suited car and me best

i dont have any detailed pics as some may/or may not be aware that i dont take pics of every bit i buy for car etc and show what "brand" ive got etc, thats just me, only pic i have is just before i sent them of to quantum

im not gonna put pic up of my car to show height etc as pointless, you could have you sills almost touching floor if you wanted with these but if its just looks your after again these are not for you and youd be wasting money

asking £950 collected but will post (will only send insured due to value of these), these are still on my car and will remain so until i have a sale, i dont even have spare set of suspension etc as sold to help foot bill for these, my loss will be someones gain

For anyone that thinks this is a bit steep, Imy! over on the teg forum bought a custom set brand new from Quantum and it was nudging just over 2k for the set, so for a set thats just been rebuilt this is a cracking deal

Proper race suspension :nice:
 
ive been in this car, this suspension is the dogs, if i didnt already have some coilys on me car id have these
 
Not sure if your looking to go back to stock suspension, but I've got a full set I've just taken off my EK4 if your interested. They've only covered 42k and are in great condition, I just upgraded to an Ek9 setup. Fire us a pm if your interested mate, otherwise glwts, these look awesome!
 
cheers for offer mate but i actually still have my original ek4 suspension somewhere, i went to quantums from oem ek9 suspension which was just incredible for a factory shock/spring

if my quantum dont sell then im simply gonna buy few different springs to try and keep running them but overall setup will depend on what friend does with car to get it handling to reasonable level (most think that simply caging, coilovers and getting proper 4 wheel alignment = great handling when in fact thats about 50% of work needed, problem is that majority of places simply dont have knowledge or equipment to make a car really handle and that includes 95% of places out there that have all the laser alignment gear, 3d imaging technloogy is catchin on a little but few places have it, gives lot of info on chassis etc that even state of the art laser gear like hunter machines dont even give)

Cool, no worries just thought I'd throw it out there. Hadn't really thought about selling the Ek4 setup, but read your post and thought it was worth asking.

I've used a firm local to me for the last 15 years to do all my customers geo checks and setup to factory spec, but they have no real clue on fast road or good track settings,I've asked a fair few times. Have yet to find anywhere within a sensible distance that have experience too which is bloody annoying.
 
dont be mis lead by thinking geo setup is answer to handling, its tiny part of process, problem at end of day though is cost so not option to many
 
hey ive got a set of these as well they are awesome. wondering if anyone has a setup guide for them tho? there's a lot of adjustment in them and im wondering if a serious brand like this has some ideas of spring rates and bump/rebound valving and settings? cheers
 
I've heard these are hardcore to the max!!! Surely we got someone hardcore enough to buy them ;)
 
would love these, if i had even half the money i would consider it! Heard alot of good things about these!

dont take this the wrong way but if you have to ask questions like that with this kind of suspension they are simply not for you, there is no setup guide, every car and person is different and setting up car with this kind of suspension needs someone with in depth chassis/handling knowledge (you could spend couple k on just bits for rest of car to make most of these)

id simply send to quantum to be fully serviced and rebuilt as required as gather you bought cheap set used so could be as good as scrap, id never buy set of used coilovers without knowing history of them and slap them on my car no matter what brand

i thought id had this thread deleted as decided on keepin mine but will keep it up as would now still sell if right buyer comes along

ps - the 1 coilover shaft i scuffed on day of fitting is no more, damaged top of shaft on pothole few weeks back so sent of to quantum to be full rebuilt few weeks ago so buyer will literally be buying like new set

i now also have aluminium top hats and softer springs installed (zeals are are still available to buyer at extra cost but only good for track car), top hats will also be at additional cost

im gonna try and get on track within couple months with this so if someone is interested they can come along and test for themselves etc
 
did you ever sell your suspension or have you put it too use?

if so how have you found it:nice:
 
still on my car, been using other cars on track so havnt had chance to test my own yet, slowly putting my car back to a daily useable car so will still get rid of these if right buyer comes along
 
bump for awesome suspension

teg trackcar i test drove had these in and they seemed spot on for the car
 
just to add, what isnt shown in pics is billet aluminium top hats that will come with these and softer kyb springs
 
Hay there mate, probably remember me from buying that brace off you before?

Forgot you were selling these if im fair!


Interested in these mate, drop me a message, would like to ask a few questions and what not.
 
open to reasonable offers on these now, someone must want this very very high end setup
 
i really really do, but just dont have the £££, GLWS thats a great price.
