Anyone using the Koni 8610 / 8611 inserts? I'm selling my coilovers, and moving to a setup more geared towards autox. These come highly recommended from a friend of mine who drives an Evo.

 

I've heard good things about them. They are inserts and you can find them at summitracing for about $300/ea. They are double adjustable (8611) and if you use stock strut bodies, you will have to shorten them to accomodate. The 8610 is single adjustable (rebound only) and if you get the 8611, a 0.5" hole will have to be drilled into the bottom of the strut tube to accomodate the bump adjuster (compression).
There are a couple of different sizes for these, so do your homework before buying them and make sure that they will fit what you need.

view the shock dyno, there are 2 different 8611's

 

Thanks for the info. I'll definitely gather as much information as I can before I make a decision to purchase.

How do you get these to fit in a strut body? I'm not familiar with inserts.

 

you need to use fabricated or awr insert housings.

this site has the housings stock style and ep style which welds the hub brackets 1.5 inches higher on the tube which gives more shock travel. They also sell the koni inserts and a rear 914 shock setup

 

What about the rears? Also, how do the inserts attach to those housings? If i had some in front of me im sure i could tell, but its hard to tell from those pictures.

 

Basically, you can't use the 8611's because of the bottom adjuster. You can use the 8610's as they are single adjustable and its done via the top of the strut. Its either that, or you can have some koni yellow sport shocks re-valved and made double adjustable where the **** is sticking out the side of the bottom of the strut thusly not in the way of anything. The rears really aren't soo bad. I would just go with 8610's or standard koni sports. On anything but a straight up all out race car, it is more important to adjust the rebound anyways (which almost all single adjust struts do) as it controls how the car transitions when turning and accelerating.
Some of this is experience, some is what I have heard. If anyone knows better than I, please don't hesitate to correct me.

for 8611s and those inserts just drill a hole in the bottom of the strut housing and u can adjust thru the hole. The rear you cant cause the eye that bolts to the hub is directly under the shock. Thats why theres no housings for the rear for sale. You can still probably make a housing like the fronts but you have to dissasemble the shock to adjust though.

I assume the inserts attatch to the housing just like on a fb or mr2. The shock slides inside and theres a threaded part on the top of the housing and a cap that threads on with a hole to allow the shock shaft to go through. You screw the cap over the shock and you're done...and for the spring, the outside gets the threads and spring perch. Hope you get it from my explanation

 

^^exactly, and the rears are what my last post was all about.

There's always converting Koni Yellows to double adjustable, but I guess it's cheaper to buy the race shock upfront.

 

Seems that way with what it costs to convert them + the original cost of the strut.
