FS:K-Sport coilover package $550
Hi everyone! I'm selling my K-Sport coil-over set, complete with two pairs of rear springs, one 6.5 kg/mm (street/track) and one 8.0 kg/mm (hardcore track/drifting). The front spring rate is 10 kg/mm. They are single-adjustable fully threaded shock bodies with adjustable locking perches and bottom-adjustable for height (front and rear). I still have the original shipping box and all hanger tags. $550 for a low-mile coil-over package (I've only done about 4000 on them).
Full "soft" is a little firmer than the stock shocks, but with much better rebound control. Full hard would be recommended for R-compound race tires and provides excellent grip and control. With an ultra-high performance street tire, the middle setting is great for a smooth track, and results in lap times which will make you the envy of all the other HPDE drivers. I've seen this done with my own car when driven by one of NASA's track instructors! The spring rates (562 lbs/in front and about 380 lbs/in rear) are set so that you don't NEED any more than the stock anti-roll bars. This is the proper method for setting up a track car (consult a suspension book or ask experts if you don't believe me). So if they work well, why am I selling them? Just to go and try something different (I'm thinking Bilsteins on Eibach Pro-kit springs. I really don't need the super-low drop the K-Sports can provide, and with my job right now I'm not getting to any track days. :banghead: <sigh> I thought originally that I'd get to the track a lot more this year. Sadly that isn't happening. Since I already have the Eibach springs, I just need a set of Bilstein shocks. If interested, send me a private message or call my cell at 760-799-0368. I'll post photos of the package later today. Eric |

so what's the minimum drop on those?
and since spring rate are so high, how does it drive on street? jumpy at rough/bumpy road? |

I'd say that freeways were a little bumpier than I prefer, but keep in mind that just one full turn up on these shocks gets VERY STIFF in a hurry. Tein Flex rates are 9 kg/mm front, 7 kg/mm rear so a 10/6.5 isn't very far off. JIC-Magic's track setup is a 10kg/mm front, 7 kg/mm rear too. Tein's rates are set up to use Tein's anti-roll bars. K-Sport's doing all the roll control with the springs. If you're coming from a typical lowering spring, the job this kit does to keep the car level is just amazing. I've tried it with the stock sways and with a set from Progress Technology. Roll control from the higher spring rates simply rules in the corners. If you're going to do a track day with R-compound tires, this is the setup to use as it really plants the outside tires in the pavement! It never felt like it was going to come out from underneath me on bump roads as long as I kept the shocks set below .75 of a turn up from full soft (which in this case was already stiffer than stock). Much less "float" than the stock shocks too. All in all, the K-Sport kit appears to be a great value... solid build, wide selection of spring rates (if you want to run a 9/6.5 setup, you can get new front springs from K-Sport directly over in Phoenix, AZ), quality bump stops provided, quality hardware and fasteners provided. I just want to try something different now. I hope this answers your questions. |
um...i don't really understand what u mean by 25.5" in the front and 25.75" for the rear.
maybe i should ask like this, how much do they lower the car? compair to stock suspension. Like the range? maybe lower from 1"to 3" something like that? |

that's the ride height measurement from the ground to the top center of the fender arch lip as noted |
very nice, well, i did some research, and find that it will most likely too stiff for what i need. I need something for daily driving, and this just wouldn't fit in for my needs. this set up is more for track use.
But it's very good price, and i find some good review on them too. good luck with the sale. |
Team, Do you happen to remember what the stock wheel arch height is?
|
it's around 27.5" give or take 1/8"

In other works, set for full soft on the shocks, this set has a plush ride, even over bumps. |
