"Lower drops" doesn't affect valving, unless you are talking about body length and where in the stroke the bump rubber engages. Stiffer springs, yes.And Steeda (and Koni) didn't design their, mind you, **~$700 for an entire set of dampers package** for a much narrower range than Ford, just for stiffer spring rates and lower drops,
Well here's the thing - how is the customer expecting to use the product?so I don't understand any criticism of a meaningless (to the targeted customer and then some) variation between two mass-produced shock valve actuals on a dyno plot. Expecting Steeda (or Koni) to offer valve-matched shocks and individually dyno each damper that goes out the door for $700 is lunacy. Ain't happening.
In my world, Koni Yellows were the first step up into Real Race Shocks, where there is an expectation that the shock forces are to some degree optimised for the car and where the adjustment knob forms some sort of useful purpose.
For Koni Yellows specifically, this is much more true than many other alternatives in the same price range (BC, JIC, Megan, etc etc etc) so if you are price-constrained, a Koni Yellow is a MUCH better starting point than most other choices. But, like you said, mass produced. That implies - and I have direct evidence of - variation shock to shock that needs a dyno to discover.
We sold Koni packages. To make them, we bought Konis in lots of 10. That was usually good for 3-4 matched sets, and a couple of oddballs. The oddballs would go in the shelf, and sometimes they'd match with oddballs from the next batch. At any given time, there were, say 3 oddballs on the shelf.
I have a distinct memory of dynoing a pair of brand new Koni Yellows whose entire operating range did not overlap anywhere on the trace. The first thing I did was check part numbers to see if they matched. The second thing I did was re-dyno my baseline (an OEM Z06 shock) to make sure something hadn't fucked up the dyno. Nope - dyno worked fine, same part numbers - just happened to hit extreme variation.
But the point is THAT CAN HAPPEN - so you have to dyno and know for sure.
As for "lunacy"... man, *everything* I sold came with a dyno plot. No exceptions. I considered it a sacred duty to the customer.
Makes sense to me. No argument here.Steeda's Pro-Action shocks are more expensive because they are a variation from the norm for Koni to produce (blue in color, valving, different stickers, and it cannibalizes their own marketed product). That's all.
Well... yes and no.I have 350 front rate springs and 1200 rear rate springs (front is a strut, ... ... beat my PB at that track be 4 seconds on a partially wet track. They do just fine. And nobody but the most seasoned of race drivers on the stiffest of chassis will notice in the real world effect of manufacturing variation between valve effectiveness on Koni Yellow (and similar valve design) shocks. Nor is it actually holding them back.
"Yes" in that, if the shocks are in the ballpark - and that ballpark can be pretty wide, depending on a whole slew of circumstances - generally speaking, shocks are rarely THE limiting factor to performance. There can be exceptions, but big hand, small map, a decent set of shocks that aren't cavitating, overheating & fading, and aren't completely wonky left to right will probably do OK.
But with that said, there can be serious time to be found via shock tuning and attention to detail if the circumstances line up to support it - and that means time spent tuning (and money spent ensuring the equipment will support tuning) isn't wasted, if you goal is maximizing performance.
If it isn't - and that's fine if it isn't, not everybody is as crazy and as financially irresponsible as you need to be to go racing - then why is there a knob on the shock in the first place? You'd be better off with a Bilstein (which has next to no part-to-part variation, but no knob) valved for that average case.
If you are a "set it and forget it" guy, Bilstein is a much better raw material than a Koni.
