Anyone here running J's racing coilovers? -manufact. by Crux. I can not find much/if any reviews on this set up in any of the forums (probably due to price of the units)

I know everyone here rocks something different, I was just wondering if anyone had experience with the Crux suspension. I know Crux currently does a lot of OEM work in Japan.

I did not want to post this in the suspension forum due to my desire to get reviews from anyone with track experience on this set up.

Thanks

The #1 concern with any track setup should be the damper... so if their advertisement just says that the dampers are X# way adjustable... and nothing else. You're probably better off getting something else.

From their site
J's Racing SPL damper are developed from their racing expierence from the past 15 yrs. They repeatedly over and over to obtain the damping data for their specification. All dampers are spec'ed carefully with street comfort and circuit performance in mind. 50mm piston (mono-tube) is used for high tunability ranges with 30 way damping adjustment. All dampers are made of billet CNC machined super high quality aluminum along with superlightweight springs. All kits comes with dust boots, adjust wrenches and urethance bump stop. Uppermounts are not included.

CAD $4,985.00 (USD $4,985.00)

So, they haven't given you any good information about the dampers they use... so to me, with the information above, they would not be on my list of options for setting the car up for competition. This doesn't mean they are bad, it just means they haven't given me any information that would allow me to make a objective choice between this setup and others.

I looked at some pictures and it looks like the rears have external reservoirs?

Sorry this is the best picture I found. I am looking for more.

Found More

I found Crux's site and found double adjustable dampers (appears to be the case). see pics.

It looks like no one has used them before?

I remember reading an article on sport compact, where they rated all the suspensions for s2k. They tested tein, spoon, js racing, moton and something else, surprisingly Spoon was rated the best then tein being 2nd or 3rd, J's, Moton all those expansive brands did not perform so well. so you might want to look into that.

and I'd think not that many people would spend 5k+ for coilovers for the rsx considering it would cost half the value of the car? *the earlier rsx-s only worth about 10k now?

spoon was basically a prepped racecar and they didn't run spec tires iirc, so it's pretty difficult to judge the 'best' suspension in that case

Not running the same tires pretty much nullifies any car comparison....

DMS "boingers" not that great. They're a club level solution type of suspension, they tend to have lots of issues so we normally call DMS "pogo sticks". Proflex or Ohlins are the ticket but at $10000 or £4000 in the UK is more of a long term investment. Then theres always what the factory works teams use, Reiger and Dynamics but prices of $12k per corner are the going rate for these suspenders!
