    323 GTX Ksport/D2 coilover installation and review thread

    Ok, so for a while now I've been looking at my options to replace my worn out GTX suspension. I really didn't mind spending a bit of money so long as I got a quality product. I really wanted adjustable ride height and adjustable dampening. Since Dirtas are fairly difficult to come by these days, and the ones you do need a good rebuild; I opted a different route. I looked at getting some KYB AGXs from a different car and retrofitting, then using them in conjunction with ground control coilovers; but after running the numbers and looking into the mods needed to make it work, I decided that for the money, I might just as well give these Knights a shot. They were a little more expensive than a shock/ground control solution, but they are a drop in solution, and rebuild kits are fairly cheap. So after searching around and looking at reviews (for different cars), I realized there isn't a whole lot of information on these coilovers. So I bit the bullet and will be the guinea pig. Hopefully this thread will provide valuable information for those also looking into these coilovers.

    So first things first, this kit is the Ksport "Kontrol Pro Damper System", part number: CMZ241-KP. Here's what you get:
    • 2X front coilovers
    • 2X rear coilovers
    • 2X adjustment wrenches
    • 6X "brake relocation brackets"
    • 6X brake line grommets
    • 4X dampener keys
    • lube packet
    • warranty card
    • instruction booklet




    Front coilovers have .310" thick anodized aluminum camber plates with adjustment markings. Studs are pressed in steel.


    Rear coilovers have .321" thick anodized aluminum mounts, non adjustable. Studs aren't actually studs, but steel button head cap screws that thread in from the bottom side.


    Coilover first impressions:
    Lower mounting bracket are quite beefy; and are cast, and post machined, machined aluminum. The threads do NOT extend all the way thru the lower mount, but rather are only present on the first 3" of the mount. All the threads seem quite nice. Everything seems to fit well with no excessive play or binding that I've found so far. All the aluminum parts seem to be anodized. Color is consistent on all the parts with no discolorations. That gives good indication that the ano was done well and has consistent thickness on all the parts.

    Accessory first impressions:
    The wrenches are stamped steel, and don't fit the perch plates all that well. They certainly will get the job done, but I wouldn't be surprised if they mark the perches while making adjustments.

    The brake line "relocation" brackets are also stamped steel and are fairly worthless as is. You WILL need to modify these to get them to hold the brake line in the OEM location. The grommets fit inside the brackets fairly well, and are split so they can be wrapped around your brake line without uninstalling them and rebleeding your system.

    Dampening wrenches are questionable. They fit inside the shocks fine, but the heads are fairly cheap plastic. We'll see how they hold up, but even if they don't any correctly sized hex wrench should get the job done.

    Instructions are about useless, but no surprise there.

    Front Installtion

    Installation is fairly straight forward. Remove old, install new. Only notable thing is the brake bracket. There is no way to bend the supplied bracket into a shape that will locate the brake line in the OEM location, so I did a bit of modification. Cut the old one in two pices, and rewelded them together. I also made a little spacer that will help hold the bracket off the coilover body.



    Installation went well, and the new bracket works good:


    yes, I'm aware EVERYTHING is rusty on my car...It's a project in the making Any ways, more to come on the rear installation hopefully tomorrow.

      Great write up, I look forward to reading more and getting your impressions of ride and build quality after you've driven on them a bit. Im looking to buy the BG GTX coilovers from them in a couple months.

          it's for the 4WD BF chassis.

          Reworking the rear brake line mount right now, it's much easier than the front.

            Do you know the difference between both?

              I assume the bolt pattern for the hub is different, but i don't know 100% for sure. I'm sure someone more knowledgeable on BFs can help us out here.

                The front struts will work on a 2wd but the back are completely different IIRC.

                  Rear installation

                  Rear install went well today. Again, it was as easy as remove and replace. I also had to shorten up the brake line bracket, and give it a little bit of a bend, but otherwise it was quite easy.

                    What was the final price, and where did you order them from?

                      the final price was $1170 with shipping. I bought them from "solowspeed" on ebay:

                      XLevel offers quality performance parts, prompt shipping (domestic and international), and honest communication for the benchmark in customer service. Our aftermarket parts offerings include everything from bumper to bumper. Whether you need replacement parts like a K&N filter or street coilovers for your daily driver, a nice set of wheels for your cruiser, or a set of pistons for your race car, we have what you need. At XLevel you can be confident in every purchase you make because we pride ourselves in offering only the parts we would be willing to install and use on our own vehicles. Please understand that some vehicles are very popular and parts do sell out from time to time while other vehicles are not so popular and may require a special order from overseas. We sell on our two websites, here on eBay, and other sites as well, so inventory numbers may not be correct. If time is a concern, please contact us prior to ordering. *** We specialize in International orders! ***


                      It was only a few hundred dollars more than going with a retrofit system, and even then I still needed to replace my top mounts, so for me I think I about broke even.

                        If the coilover are modded,and 2 pieces of aluminium is welded to the coilover, the lower trailing arm should be possible to mount? What other differences between 2wd and 4wd are there??

                            Still haven't driven on them. This Gtx is a bit of a project car.
