I was going to do a review of these after I rode on them for a while. Since this is here, I will add to it. Keep in mind, I am noob and not experienced with any real quality coilover system on the S13. I have only Koni Damper/Matched Spring combo to compare to.
Product: EMUSA dampening adjustable coilover kit for S13 $550 Shipped
Time of review: 6 months after first install.
Driver/Purpose: Street use, daily driver, adjustability enough to lower, but not slam. To not invest $$$$ into coilovers that will require rebuilding because of terrible/abusive local road conditions for which most coilovers weren't designed to handle.
Vehicle Info: All bushings either poly or pillowball, stock configuration LCA's and spindles. SR PoWAAA!! Rides on stock size 15"s and 17"s with 225/45's
Service: When I installed them, upon initial dampening adjustment, one adjustment screw just turned and turned and turned. I was unable to get a start point and end point. It was like something was broke inside.
EMUSA had great communication and sent me out a new single front coilover. They don't usually do this, they said, but went ahead and did it for me. (Initially, they wanted me to remove the entire kit from the car and send it back as a whole.) I was able to drive my car around while waiting for the new coilover. When it arrived promply, I swapped it out and then sent the "broken" one back, postage paid by EMUSA. Very pleased.
Performance: The quality is not the greatest in the materials used. The tophats, as mentioned before, are cheap in feel and the screws for the adjustment at the top don't thread in nice and smooth and I feared stripping them during install. With that said, none of them stripped.
My 17 x 8.5 offset 25 wheels in the front rubbed the rubber spring seat/gasket, but never touched. I didn't even notice till a much later inspection and added a 3mm spacer to give me some more clearance.
The springs "feel" on the soft side, 8k F / 6k R is standard issue I believe. Even with the upgraded sway bars I have and poly bushings, I still experience farily extensive body roll. I am pretty low and don't have roll correction! They soak up bumps very well and I feel more secure, less skipping around, than I did on AGX/TIEN combo. Otherwise, the handling seems good for daily and spirited driving purposes. The body is controlled acceptably and since the spring rates are what they are, the rest of the suspension is allowed to work and stroke well under most conditions. They almost feel like spring/shock combo, other than the usual rear end buck on large bumps that seems unavoidable when you have anything other than spring/shock combo. All and all, very pleased with the ride and handling. Also, no compaints during the girlfriend test.
Conclusion: Amazing value and bang for buck coilover. "USA-made" product that is domestically rebuildable or damper replaceable. I am still waiting for them to blow any day. The thing is, when they do, I will give no FUKK, cause they are so cheap and I'll just grab a new damper from EMUSA and freshen it up.
