I've been searching for a suspension for over a year. I did a lot of seat-of-the-pants testing from the passenger seat of a dozen or so NSX's. I determined my preference and made the decision to buy -- only to discover my choice was no longer in production. So the search continued.
After reading the acclaims of the JRZ suspension by Anil (serialNSXer) and talking to Jon Martin of Cerritos Acura, I ordered the JRZ coilovers. It's kind of a new setup, so I hadn't had the chance to "seat-dyno" it. I put a lot of trust in these guys, so only time will tell if they are worthy. (I'm not too worried.)
The dampers are 2-way adjustable and the springs that come with the setup are Eibach... 300 lb/in. in front and 350 lb/in. in the rear. That's approximately equivalent to 5.4kg/mm and 6.3kg/mm respectively.
I went to Darin of West End Alignment for install, corner balance, and alignment. Darin did a fantastic job! He balanced the car on the 3rd try and aligned the car the "old-school" way.
The car weighed in at 3029 lbs with about 16 gallons of gas in the fuel tank. So, based on 6.35 pounds per gallon of premium (API gravity of 54), I figure the car weights approximately 2927 lbs. without fuel.
I need to evaluate this suspension for a while before I can give a good assessment, but if my drive back home from West End is any indication of their performance, I can say that the car has never felt so razor-sharp in the steering department.
The ride is near stock, yet I could feel the imperfections in the road as the car just seemed to be sucked down to the pavement. I just didn't notice that "air-born" feeling like I noticed with the stock suspension when the undulations in the pavement oscillated the wheels. There was no pogo effect whatsoever.
Weigh distribution...
Final result...
