KSport and Tein Coilovers - more info requested

You will not need a camber kit with the kSports, but you will for the Tein. It sounds like you want

The ksports have superior adjustability over the Teins, and have much higher rear spring rates. There is not a very good chance you will be able to have any custom work done to your ksports since they are not serviced stateside. Teins are serviced stateside, so they can do whatever you want to them, as long as you can afford it.

I have found through hours of testing that you can drop the ksports on their balls and the tires not rub, but in order to do this you have to shorten the shock travel by preloading the shock so that it is artificially firmer. There is a risk to this, which would be premature wear, and possible damage if you hit a deep enough pothole. I have also found, that no matter what, you will need to roll the rear fender. For a short time I drove around with only 1/4 of gap between the tire and the inner fender, which from the outside looks like the top of the tire is flush or slightly tucked with the top of the fender. I had to preload the shock quite a bit for it not to rub, and it was an extremely firm ride. After hitting a deep pothole or two, and feeling the shock bottom out, I raised it back up. Currently I am running about 1/2" gap in the front, and 3/4 gap in the rear, with a slight amount of preload on the shocks. I have hit some pretty rough roads and the shock hasnt bottomed out and the tire doesnt rub.

I have used the tein basic dampers on my other vehicles. I can comment a little bit on those. The shock travel is not adjustable on them, so when you lower the spring down on the shock, it is preloading the shock, making it artificially firmer, but with the same risks as stated above. The major difference between the two sets when comparing the preloaded conditions, is that the kSports have higher spring rates, which make them a better choice.

With either of these systems, dropping it very low (making the tire appear tucked), and making the shock firm enough to not rub, will inevetable cause the shock to fail or be damaged. So if this is for "show" purposes, either set will do the job, if it's for daily driver purposes, neither set may meet your needs. The lowest I can get it without the shocks bottoming out, or the tires rubbing was 4" drop in the front (-0.5 camber) and 3.75" drop in the rear (-0.8 camber). With heavy passengers or towing, you would need to raise the rear to a 3.5" drop. If this sounds low enough, you may want to consider the kSports.

To snuff this all out, you could spend a lot of money and have the Teins revalved, and buy higher spring rates. Expect to pay about $2300 for a revalved set with higher spring rates, not to mention you will need to purchase a front camber kit.

Personally, I am a Tein guy. I have put Teins on everything I have owned, except for the element. Unfortunetly Tein does not sell the product I needed, so I had to go with the kSports. I am more then happy with the kSports, the only thing I am a little shaky about is their durability, and support if something goes wrong. Time will tell.
