do i need to modify the tower caps? or modify anything else for that matter? what are these front strut inserts the OP is talking about?

There are plenty of youtube videos on how to modify a strut for a Koni insert. Have a look there. Since you have a Cobalt, your strut mounts need no modification. Make sure you have a good way of cutting the strut. Do not crush it, or cut it too short!
Hey Warren follow up with Jeff Wong at PPUSA? over two months and still waiting, money up front. Good news is he stroked front struts I purchased off root beers car and sent to him so he could check and then asemble into the core front housing; so we will see results. In the meantime, I cant beleive we have missed all this time to check out re valved front and rear konis.

I dont get what i need to cut though? the koni strut?
koni front is an insert. it is inserted in a stock strut housing.
get stock strut and cut top off housing to remove guts. Use a pipe cutter to do so. Then carefully drill hole in bottom of strut. insert koni INSERT (get it?) and then bolt up at the bottom.
etc.
Warren I think a delrin ring for the bottom of the insert or something better than Delrin may stabilize the insert better. I have a set of wrecked koni inserts that the bolt hole at the bottom got screwed up, I may fool with it and let you know what I find.

I don't have any pull w/ Jeff. First time I emailed him was when you introduced me. Why is it that shock companies are universally so slow when you're just a small timer.
Keep me updated though. Curious how they turn out. I like replacing my Konis after a while, since I beat them up pretty good. Limited track events this year though

So for other folks, I seem to have nuked 1 set of fronts and 1 set of rears. I'm hoping that running appropriate springs, which DON'T bottom out all the time will keep this from happening.
I knew they were gone because in the front, the knob wasn't turning the same amount of turns it used to, and in the back, I could feel the car misbehaving. The front one went soft. I bent the rear one somehow. Probably curb hopping at the track. This happened some time ago, but I though I'd share it in this thread.

Is this for Allan? Still think the off the shelf ones would have sufficed for now

Maybe singular. Let me know if you're still coming down to Baltimore.

no clue with Jeff he is a nice guy
Alan wants the best. I hate to fail. add headlight retrofits and carbon bodywork to the shock companies are universally slow lol.

You have to cut the OEM strut to put the Koni insert in it.
Woah, sorry, had the page up for a while before I responded!

They're inserts like everyone is telling you. It even says so on the Koni pages, and the places that sell them say so too.

The fronts are inserts to the struts. The rears are not struts, just shocks and they bolt right on.

I'm going to a track day on the 12th. I won't know until then, unless there's some sort of difference that I don't expect when just driving back and forth to Dunkin Donuts in the morning.

Night and day difference, even on the street if you are running stiffer springs, and a big rear bar.

I'm going to try to put the rears on Sunday. Depends on the weather.
