NICOclub's Project G37 When we left off last time we had just installed an oil cooler on our project G37. However, we had mentioned the reason we chose to go with an oil cooler as our first modification was because of oil temperature problems at the track causing the ECU to lower the redline to 6100 RPMs. We had also mentioned a problem with the clutch and brake fluid overheating as well as the pads fading. While we intend to address these other issues before we return to the track, in the mean time we thought we’d throw in a mod that we can feel the difference with. I'm not talking about a power adder, but rather suspension. We didn’t want to compromise ride comfort, yet we wanted the ability to stiffen the suspension when we are at the track. We also wanted a slightly sleeker look by lowering the car, but just enough to make it look “right.” Finally, we didn’t want to put extra stress on the OEM shocks by just installing lowering springs. This left us with really only one option—coilovers.
After the rear shocks have been installed, re-install both rear wheels and lower the car. Roll the car a few feet (or drive it) to allow the suspension to settle and re-measure the ride height. We found that when the kit was installed without any ride height adjustments made, the car was almost exactly the same height as when we started. Like we mentioned before, the front of the car measured 1” higher than the rear. To give the car a much cleaner stance without compromising much ground clearance, we chose to lower the front of the car 1” to match the rear. We left the rear the stock height. To lower the vehicle in the front, jack up the car and remove the wheels again. Use the supplied adjustment wrenches from BC Racing and loosen the lower adjustment lock. Do not loosen the upper adjustment lock because this will change the spring tension. The BC Racing coilovers can lower the vehicle and maintain the same spring rate by screwing the threaded portion of the shock down into the lower shock body. Measure the amount you wish to lower the car on the threads before adjusting it. Screw the shock into the lower shock body the desired distance, then retighten the adjustment lock ring. You will need to loosen the brake line bracket from the shock so that you can turn the shock assembly as you thread it into the lower shock body. Once the shock is adjusted to the desired point and tightened, tighten the brake line bracket and re-install the wheel. Do the same for both sides and re-measure your ride height. Overall installation is straight forward, and we are delighted with the results. While we haven’t had a chance to take the car to the track yet, we have driven it on the street. The suspension is easily adjustable to match the stock ride comfort, but also has plenty of room to stiffen it up for the track. When we come back to this project, we plan to address the brake and clutch issues as our final step before we head back to the track. So keep checking back as we continue NICO’s Project G37!
