So the 20s have my RX300 shaking slightly between 50-65 mph. I've read around and guess I'm gonna have to get some hubcentric rings. Anybody know where I can get some for cheap? I seen some polycarbon ones on ebay today for like $12 shipped. Is there a major difference between those and metal ones? And should I go ahead and get my alignment now or wait until I get my springs installed. Thanks

 

You need to do 4 wheel alignment for any change in geometry of the suspension. Hub centric rings just relieve the load off wheel studs. It is a good idea to get them, I have used both metal and polycarbon, frankly I can't tell the difference since there is no noise with neither.
Check our lug nuts, make sure they are torque to spec. Stock is 76 lb-ft, aftermarket rims usually require higher torque.

 

Ok, so I guess ill go order them from ebay today. So should I drop the car 1st or get the alignment 1st?

 

If your alignement is bad now, you will get abnormal tire wear, poor mpg and in some strange conditions have handling problems (in extreme cases only .. minor alignment issues are limited to tire wear pattern). Shake and shimmy is usually not an alignment problem (unless somehting is loose).

When you lower, I am almost certain your stance will change and depending upon what else gets touched an alignement will be required.

So why go through the expense twice, unless there is a long wait period till you have the rx lowered.

Yeah thanks, its just that my springs are takin forever. Thats what I get for getting them for a low price on ebay. I guess I'll just wait until I get them installed 1st
