Hello everyone one, i am from Qatar, i need your help regarding my lc300, i tried everything i can went to different shops without solving the issue, i figured out to reach out you lovely people of Australia since we are the only two regions in the world who heavily use the lc300, excuse me for the long introduction and here i go, the issue is since i installed my mrr dobinsons with 2" dobinsons coilovers and 285/70/17 yokohamas, the car is bouncing a little bit from the front side ( i think it's from the front from what i feel ) , it's very annoying and uncomfortable, it's not that strong in a dangerous way, but it's as i said annoying, i mean i even find it difficult to drink a cup of tea, the bouncing happens on speeds +120 km/h, what confuses me it's not always happening, even on the same road sometimes it bounces and when i come different day to the same road it doesn't, i replaced the dobinsons coilovers with king springs 1" lift , same issue, tried different repound and compression settings based on different recommendations from the guys who installed it for me and feom dobinsons themselves, the issue still exists, the gas psi now is at 160 psi( i tried 200 psi then 150 psi ), My car is GX LC300 (4.0 petrol engine), except of the suspension changes i mentioned above everything is stock, there is no added weight at all, did anyone had or read about this issue before ? Can you please help me to solve this issue? The latest advice i was given is that since my car the 4.0 engine (not the twin turbo one) it somehow light and thats why dobinsons shocks are causing the bouncing!! What do you think ?
