Clunky and Loud

While the KSports’ offer a great price to ride ratio they tend to be a bit loud in the cabin. I could drive over a pebble and the thump inside the cabin was more like hitting a 3 inch deep pot hole. Granted the suspension is stiff making the springs hard to flex and the frame was taking most of the impact which would explain the harsh noises. However; those running Tein Flex which is also very stiff have no complaints of obtrusive cabin noise. The Flex also comes with Tein’s "silencing rubber" between the tightest coils which they claim reduces that cabin noise. None the less, Tein Flex is nearly twice as expensive as the Kontrol Pro’s.

Aggressively Stiff

The Kontrol Pro’s are incredibly stiff which is great for track driving or hitting the back roads, but for the daily commute a softer ride is always a welcome luxury. You can get custom spring rates straight from the factory, however; that seems counter intuitive. By the time you pay for your custom springs on your KSports you had might as well picked up some Buddy Club N+ or Tein CS. If you’re looking to run stiff on the track and back roads then the KSports are the coil overs for you.

Lock Rings Seized Up

Ah, the real reason why I ditched the KSports. Not that long ago I had to pick up a set of new tires. Being new, these tires had a lot more tread which lead to having to raise the car back up a bit to prevent rubbing. When I went to pop the lock ring in the back it wouldn’t come loose. I hit it with a screw driver, a mallet, the "keys," I heated them with a torch, I cooled them with ice. I shot them with PB Blaster, silicon spray and WD–40, nothing worked.

I can’t entirely blame this on the coil over. Living in Oregon the DOT sprays the roads with de-icer during the winter which can have very negative side effects on almost all of your cars moving parts, including lock rings. With a little more preventative maintenance this could have possibly been avoided. However; one side of me feels that the part should have been made with enough quality to not require any kind of maintenance. I have to remember that all aftermarket parts for vehicles are intended for "off-road purposes only" meaning that they are intended for track conditions and fair weather.

Conclusion

I ended up pulling the KSports off and putting my OEM struts with Tein H–Tech springs back on. Granted I am about an inch higher off the ground now I could not be more satisfied. The ride is much softer, no more clunks and thumps and the car drives more like a it did from the factory. The Tein’s offer a nice compromise between performance and comfort, the next step would just be adding some Koni Yellows for additional adjustments.

Speaking of Tein, I have ridden on basics and SS, the basics were in a 2006 TSX and the SS where on a 2007 TSX and 2004 TL, the latter having EDFC. For the basics I was not to impressed, first they seem to have a chronic issues with developing a squeaking issue in the rear on TSX set-ups and second, they have no dampening force adjustment. Granted, Basics are an entry level coil over and at around $750.00 +/- $100.00 they are a fairly good budget choice.

The SS on the other hand I have to admit are much nicer than my K-Sports. Softer and smoother rebound, very nice spring rates and dampening force adjustment via EDFC or the old manual method. This should be expect of a coil over system costing over $1000.00 on average. The ability to use EDFC even though listed as incompatible with TSX SS applications is a definite convienience.

The K-Sports offer a wonderful middle of the line coil over, I’d say falling somewhere between Tein Basics and Tein SS. Another advantage to the K-Sports is you can adjust the shock body for ride height as opposed to adjusting the spring perch seen with most Tein set ups (to see how this works read the K-Sport manual by clicking here). This allows you to keep the full amount of suspension travel and lower your ride height to a near bagged appearance.

Over the course of my two weeks of ownership I have dropped another half inch for a total of about 3 inches of drop (7.62 centimeters) and still have about another inch and a half (3.81 centimeters) to go before the K-sports are tapped out. With this now lower stance I have noticed a bit of fender rub over bouncy corners at a higher rate of speed, to remedy this I have adjust the dampening force to be firmer to compensate for the added body roll of a hard turn into a bump.

Adjusting ride height with the K-Sports is fairly simple and straight forward. Raise the vehicle up and place it on stands, remove the wheels (you can get away with leaving the font wheels on), take a flat head screw driver (K-Sport suggests a brass punch), and a hammer then tap the base collar counter clock wise to loosen it. Adjust the collar up to the amount of drop you would like to add, now grab the collars and spring in your hand and turn clockwise until your base collar is pressed against the shock body. Take your hammer and screwdriver and tap the base collar clockwise to lock it and check to make sure the spring perch collars did now loosen. That’s it. It took me about 45 minutes to adjust all four corners.

Overall; these coil overs are impressive for their price and should be considered by anyone looking for a decent set of coil overs on a budget, because lets face it, we can’t all afford a $1600.00+ set of coil overs but would sure like to have some of the high end coil over adjustments.
