***update***

got new lca. shaking at 60 is almost completely gone though i think i need new motor mounts too... sh* T these cars are a mission. plus now my rotors feel warped so imma get new rotors and pads to see if it helps with the very suddle shaking still happening. lca i got were off a soarer from japan. supposidly the stock bushings are different. they look stronger, i feel the road much more!!!

 

I guess I got lucky with my sc4. Not much shaking at all at 60

 

Sounds good CMH. Let me know if you feel any difference after the motor mounts. Have you installed new drive shaft flex joint things too?

 

lol.. u should sell it to me. i was offered a mint 99 sc300 but damn it i want a 400..

damn. no. should i? man this shaking thing blows. imma start a fund for r&d on rubber rims, maybe that will help us out

 

Here's an update since I started this thread. Lol. All I did was take my drivers side wheels off to test fit my 19's and re-installed my 16's. Shaking gone. I have 2 lug patterns for them. I think they use the wrong pattern. I still get a slight shaking but I'll look into that later.

 

***update again***
Brake pads,rotors and calipers serviced and car still has slight shake... But rides way better. I think imma sell this crap

 

So.. I should always buy new tires?
