I didn't stutter :shrug:

But on the other end I'm at 425. On a shock only "rated" to 300.

The main issue, is there's very little shape to the curves. The actual stiffness is an issue on the rear rebound, but the more important element is the shape of the curves.

The rebound is pretty much a linear line, which would suggest a piston that's allowing a lot of bleed around it rather than through it. That's poor design/manufacture/components.

Bump is similar, but clearly has a knee point where the curve 'blow-off' from the initial rate. Still, there's potential for a more low speed bump to keep those stiff springs under control for traction.

Poor mfg qc? Never gonna happen in a $300 Chinese product.

The problem is too LITTLE rebound to handle the heavy rates. the shocks are not in control of the spring.




Now the question is. Is Bearnie going to revalve them?

Step back from race track spring rates to performance street. The current valving with a spring change in the rear works just fine. Especially for the target market of entry level street / weekend warrior.

All the further "changes" and development are going to do is run up the cost. Keep them cheap, get more people started.

I'll give you that, but I still don't like the curves.

I'm not even looking at it from a track standpoint, you need the rebound the control the spring rates. I'm also no shock expert.

But with the reports of failure and the pictures of seen of the lack of travel; I'll pass. You can easily get a budget OTS shock / OBX coilovers for just a little more and have a little better piece of mind knowing your running konis or illumnias that may or may not fail.


I was trolling over at the m.net thread, not over here. I had considered them for a while since I DD the car and was looking for something cheaper yet spirited while maintaining a more comfortable ride. I ended up pruchasing used illunimas for $250, but had to resell them cause they required me to get shorter springs than what I'm running on my konis.

we'll let Bernie pontificate on the curves and quality.

I'm still adamant the CR failures and lack of travel are due to dumbass installs. Savingtons failures....dunno??? what springs was he on?

you; troll....NFW

there's nothing wrong with adjusters over shocks...That's all we could run in IT in the late 80's early 90's. We screwed with them until they worked.
Something I want Bernie to expound on. I've long held that the shock can be successful even if the damping capabilities are 75% of the spring rate. That they don't need to match each other 1:1. Because on a rudimentary level all were trying to do is slow the energy being input or removed from the spring.

65% is the "target" for critical rebound damping. The curves look linear to me-not so good. Softening the rear springs would probably make them much better for daily usage. The raceland rears remind me of Koni STR shocks.

Hard to do; they're twin-tube shocks masquerading as mono-tube shocks.

what is the body length compared to a bilstein?

Thucydides

Dunno.

I know the RL's are 1.5" F / 1" R shorter than stock

Bernie tells me that what you think is the shock when you're looking at a Raceland is really just a very pretty cover for a rather nondescript twin tube shock that is slid inside the cover. Hmmm; does that make it a triple tube?

Turns out you can open the aluminum cover and remove the steel twin shock inside. The actual shock has no markings or descriptions of any kind. It could be any number of oem style daily driver shocks built in China and sent out under various labels as economical replacement shocks for grandma's decrepit AMC Hornet. It probably wouldn't be too bad if it were, say, a GR-2 or something decent; chances are, it's something quite a bit lower on the low cost bid sheet.

But you've got to hand it to Raceland for their very clever marketing. Doll up the outside with pretty powder coated springs and an anodized aluminum camouflage cover, and chuck whatever you have extra of on the shelf into the inside. Charge $300 and profit.

So is Bernie gonna throw some Penske shocks inside the Raceland shell and create the ultimate sleeper shock?

mcarp22

Excellent!



Now it's just a matter of finding inserts that will fit!

sjmarcy

Test post.

Thucydides

That would be Penske shocks inside a monroe body.

oh look, Bilstein yellow


and Koni red


contrary to your opinion, I think this is a great revelation and opens possibilities when the shocks do go away.
Insets have been around for decades. I guess Koni, Bilsein, KYB; et al also stole the Russian nesting game. Oh, they beat Raceland to the punch because I remember them back in the early 70's
Now we get a decent set of cheap adjustable bodies we can tinker with after getting 30k miles out of them.

These shocks have yet to surprise me. I got exactly, if not more than I paid for.

Only problem with that thinking is that you can buy Ebay coilovers for $75.

what will you install them on?
