Andrew sometimes the jdm tax is a little unreasonable especially for some little aluminum washers

I paid the jdm tax on js racing offset ball joints only to be irritated by the annoying amount of erroneous information even on their own damn site.

My friends paid the jdm tax on the asm exhaust only to have it fall apart on them.

I invite everyone on s2ki to stop listening to anything this person has to say about driving and automotive engineering.Same goes for this person. Completely missing the point. Speaking on something you have no experience testing is a waste of everyone's time, including your own.

Everybody has a different opinion on it. Some people find it useful and some people cannot imagine its usefulness. The fact is, torquing the subframe will prevent the subframe from moving. There's something different that everybody is missing the point on, but again, it's purely how OCD you get about tolerances. Some people don't care and hence they will automatically feel nothing is benefited from the modification.

I can tell you this much though, you can't convey the "feel" you get from the modification. That's something that has to be understood for yourself. You can tell someone to just relax, but until they understand that feeling of being relaxed, it's hard to communicate that expression properly.

I'll tell you now that the subframe doesn't slide. It may shift after a few tens of thousands of track miles, but that's easily correctable with a good suspension/alignment guy who knows what he's doing. There's also the fancy shifting of the subframe in order to bandaid an alignment problem due to a slightly bent control arm/knuckle too.

The Rigid Collars don't prevent the slide. Hell, if it's going to slide, the material itself is so thin and malleable that you might just cut through the collar rendering the collar useless.

JDM tax is definitely true, but don't forget the cost to ship something overseas will be incorporated in the cost. If you even shipped a set of wheels via air freight from Japan, you'll know that it's a $700 fee despite seeing some "lower cost" on the website. Shipping via boat is way cheaper with the right amount of components in the container, but you don't know when it'll arrive since it's based on when the shipper wants to ship the container over. If you're purchasing from these guys in Singapore, expect to pay around $70-80 in shipping. IMHO, not worth it to have something shipped overseas for something you can get stateside at a much quicker turnaround time.

 

Ouch, least you don't come off as pompous and arrogant.
I've tested it on another vehicle (no not a prius, ha!). Except, instead of just installing them and empirically saying they work (like you did), I also made sure to torque everything down prior to install, did a test... then installed them, test... then uninstalled them, test.

Guess what, no change. skid-pad numbers stayed the same, lateral grip slightly worse, slalom speeds... yep, the same. Also, on the S2000, I've marked all my subframe bolts with whiteout. Never moved, never shifted. This is after aggressive driving on kerbing, sliding it off track once backwards, etc, etc.

 

You have missed the point completely.

 

Show me someone who has lowered their lap times from these and I will change my opinion.

 

No he just has a different opinion, and real world data that leads him to think how he does. And that is okay

 

It's not slide that they prevent, it's flex and distortion of the subframe under load that these address. Those gaps in those bolt holes become stress concentrations when the subframe is loaded in situations like cornering and threshold braking. Putting collars there makes the area more rigid.

 

I just thought I should point out that linked product is actually more expensive than the Spoon kit. They sell their S2000 offering as a separate front and rear set totaling $240 before shipping. You can have the Spoon set (complete front and back) for less than $200 prior to shipping (http://www.nengun.com/spoon/sub-frame-rigid-collar-kit).

 

Shipping from Nengun is quite a bit more than you'd expect. LOL!

 

I've ordered from them a few times, depends on what option you use. As long as you're not in a rush, it shouldn't be too bad. FedEx 7 day still brings you in under the pricing for just the parts with the RZ Crew.
