Hi,
sorry for being late, I did fit the kit to my GTR. I did some drive test on various streets to see how those coilovers respond.
I got them lowered to the end in three corners, the rear right corner will get lower than the rest if it's lowered to the end, I don't know why, maybe it's something in my car !!! or it's common in all BNR32 with those coilovers !!! I'm not sure. anyway, I couldn't do a 100% accurate measurement to all corners height, it was done using a regular foot measurement tool.
regarding height of the car, you won't be able to completely drop it to the ground, but it's more than enough for normal street use. if it's lower than that, I might suffer when facing any speed control pump on the road. furthermore, I like how my car looks on that height level.
I've tested the drive on different street condition, and different speeds. in all cases, the drive was really comfortable with very minor bouncing comparing with other stiff coilovers.
on normal streets, when I go on relatively normal speed, say 75 - 80 km, drive is smooth with nothing to mark. if I exceed that speed to more than 95 km, drive still smooth, but when I hit a pumpy spot on the road, or to be more specific, when there is a big sharp difference in road height, the front tires slightly touch the inner fender covers. however, I haven't had the chance to play with the damping force level yet. I think it might make a difference on other damping level.
on highways, I reached a speed of 195 km and the drive is comfortable and stable.
body rollover. the old kit I've removed was stiffer, so now I have some body rollover. not like the OEM dampers, but its there. however, as I mentioned, damping force still untouched. and I don't know what damping level I have now. it's because I had a water leak underneath the intake manifold and I had to take my car to the workshop and get it fixed. that thing had interrupted the testing process
nowadays, I'm taking the car again to the workshop to complete the project and put the rest of the parts. going serious with the GTK 850 turbo, full modified fuel system, AEM EMS,,, etc.
when I have the chance to play with the damping force, I'll let you know.
