Try to remember that my shocks were built for a stock-class autocross car, where overdamped low-speed rebound is often used as a replacement for springs. At full stiff(I honestly never ran them more than once that high), the car had tons of initial transient response, before it immediately overloaded the tire.

 

[QUOTE=alvanderp,Jul 11 2010, 04:18 PM]I'll try and dig up the invoice, but I'm 99% sure its an L/VDP piston.

Are you trying to say that in your experience Penske linear rebound pistons flatten out like that at x force(defined by the shim stack) regardless of the position of the adjuster?

 

Perhaps I should clarify, I can sort of see your point on my front shock because the flattening effect is somewhat progressive, but on the rears, the knee is pretty pronounced. I'd be surprised if the force termination was that pronounced on a Linear piston, but it's hard to see on your dynos because the plots stop at 5 in/sec. When it all comes down to it we are arguing semantics, I just want the shocks to do what I want

 

I did not choose the valving on my shocks -- the previous owner was adapting a very high rate linear valving for use on pavement with humps and bumps. I am not sure why he chose such a high maximum force, but it did work a lot better on irregular surfaces than the pure linear valving. And like Drew's shocks, mine were built for Stock.

My main point was that Drew probably knows what pistons are in his shocks, and it's not impossible that his F-v curve was produced by the pistons he says he has.

 

Yeah there is definitely some semantics in the discussion. That can easily happen in an online text discussion.

I think your fronts will likely work for STR and worth a try before doing a re-valve.

Any plots for the rears?

 

Yeah I ran them this weekend and they worked fine, I'd just like them to be a bit more palatable on the street.

The rear plots are in the same link, just scroll down

 

Wow I feel like a real knuckle head not noticing the second page!

The rears look they would work as well. You may need more compression over what the plot shows. The rebound does have a digressive curve for the rears.

I am surprised at how little the compression adjustment changes from full soft to full firm. It almost looks like an 8100 compression adjuster.

 

has anyone found a double adj. mono tube coilover set-up thats under $2500? Besides tcklines which you cant get any more.

speaking of tcklines, what model koni's are they? Could I just a set and re-valve them through koni?

 

how about used? you can get in that ballpark.. i recently picked up a set of moton clubsports for not much more than that.. complete and ready to bolt in. they may need a rebuild sooner than later but at least i have my foot in the door to knob turning, suspension setup fun

 

TC Klines are the 8242 twin tube, I believe, and the S2000 fitment was a special run made for TC Kline.

For somewhere around $3000, you can get a complete bolt-on solution with the 30-series monotube Konis through ProParts.
