KSport Coilovers: All About 'Em

[RandallNeighbour]

I got my replacement rear springs in Friday and haven't had time to post the particulars, but wanted to do it for historical info should anyone read this thread fifty years from now....

The standard Ksport Koilover setup has the following spring rates on their units designed for the Porsche Boxster:

Front - 5.3 kg (stamped 10.5-205)
Rear - 9 kg (stamped 11.5-180)

Insite has recommended that anyone buying a set of Ksport Koilovers for their Boxster should order them with a special request for a different spring rate on the back struts that is closer to the rate of the fronts.

So, the change one would make would be to ask for the rear struts to be fitted with 7.2 kg springs that carry a factory stamp of 11-180.

I know the factory numbers between the 9 and 7.2's are very close (.5) but I verified this twice with Anthony in sales at Ksportusa just to make sure they are 7.2's and not 8's or 8.5's.

And that's all I have to say about spring rates right now. Bye.

i recommend either of the following:

5.3 front / 7.2 rear (300lb / 400lb) for medium stiffness

OR

7.2 front / 9.0 rear (400lb / 500lb) for firm stiffness


FYI, the 5.3/7.2 combo is closer to the PSS9 rates.

I am glad to see everyone has come around to see the K-sports as the are-a pretty darn good product for the money. Mine are still going strong. I had a slight problem with one of them, a valve blew out and K-sport stood by their warranty like pros. They sent me out a replacement coilover before I sent the blown one back so that I wouldn't lose any road time. Takes long enough to change these things out as it is. Anyway, I just wanted to throw in my $.02 here. For what it's worth I know a lot of people think K-sport is a johnny come lately to this but the fact is that they have been making coilovers in Japan for quite a while and their product is very well known and trusted in many circles.

Randall- I was happy to read that my opinion was a factor in your purchase. I am sure you are gonna enjoy them. You are getting top rate advice from insite, I couldn't possibly add anything to what he has already said but if you ever have any questions you are always welcome to call me and I'll do my best to help you out.

I wouldn't even think about putting these on a car without the helper springs on the front and back.

guys -

i spoke to TCS about putting together a group buy. basically, i can have them put together kits that include either medium or firm rates (300/400 or 400/500) along with the right mounting hardware. they think they can do substantially better than $1,088 shipped if several people order at once. PM me if you're interested in a set of these (once i've reviewed them, clearly) so i can guage the number of people that are looking to purchase.

FYI, since i ordered mine with dyno plots & custom rates, they're taking a little longer than usual. i'll probably receive them mid-week and install next week.

Hey insite,

If your set up turns out great I'd be willing to give the coil overs a shot.

After you review and give us a good impression one way or another I will decide. I have had the money ear marked for coilovers for a while. It is my stash cash that the wife does not know about so shhh....

Thanks for being the test mule.


have a beer on me!

Insite, if your setup turns out great, I'd be willing to give the coil overs a TEST DRIVE.
