I want to check with you who have made your subframe bushings stiffer (collar, solid, etc). I had solids on my s14 for a while, then switched to nismo rubber. Well the clunk is still there though not as loud. I've managed to get my shifting perfect 80% of the time, but whenever the shifting is off by only a slight bit I hear this clunk from the rear, and I do feel a tiny jolt/play in the driveline as I usually let the clutch out pretty fast.
Is this normal? My past s13 never had this problem. The clutch on both cars is stock and very strong. The shift shock on the s13 was much smoother and doesn't jerk the driveline as hard. The jolt on the s13 feels more gradual, like it pulls the rpm in place, whereas on the s14 I feel metal parts hitting each other.
The rear end backlash is to spec, diff is s15 hlsd, so it should be fairly quiet. The s13 had all stock bushings & motor mounts in great condition; the s14 has some stiffer rubber & urethane combo. I doubt the bushings affect it that much. Obviously all FR cars have some play there - prop shaft would turn a few degrees before actually driving the rear end. My friend's RX-7 has about the same amount of prop shaft play, but it doesn't shock the driveline like on my car.
I've also tried twisting the u-joints by hand and felt no play (stock shaft). Everything on the car is tight and torqued to spec.
Any idea?
