i just had mine lowered on road magnets 2 weeks ago, with no shakes at all. i did an alignment right after lowering, and i think you need to do it asap. i got one more coming up after 1k km.

on alignment right after lowering:

i don't know if it's your wheel alignment that's causing the shakes, but just get it done.

I've had RM springs on my AWD for over 30k and no issues. I had a slight shake at one point and it turned out to be a wheel out of balance. Make sure your tires are good. and the alignment is correct.
BTW, I love the way the car feels on these. It made it just right. They did take a few months to really settle in.

i wish i have 2" to lower my car ><

I think 1.3" is max i would go for, but too bad they only made the springs to drop 2"

your thinking in RWD terms... AWD is about 1 inch higher than the stock RWD so his 2 inch drop is the same as a 1 inch drop on a RWD.

I have owned and drove on RM's and loved it for what it was. Way better than stock.

Some AWD owners experience vibrations when changing from stock springs however. The guy I bought my BCR coils from had vibrations on Springs and Coils. I have his exact coils and no issues. I have a 06 with a 12/05 build date for reference.

mine is AWD and i went to parking lot to measure the height, but 2" looks very low, you sure it works with no problem?

Maybe i should take a pictures when i do the measurement. So you guys can give some suggestions. If i can get the springs instead of coils that would be great, cuz for coils i will need to save a little bit first

yeah, i owned the springs "shuturmout" just installed and had no problems. I dont know what kind of a gap you can expect on 18's but I had 20's and minimal to no gap. I will look for some pics later tonight if I can find them.

Coils are sick though because you can adjust the height anytime you want and dampening as well.

You should still go with the coils for better performance. Just keep an eye out for a used set.

totally agree with you, for immediately drops i can go with springs and in the mean while look for a used set of BC Racing

20's with no gap any rubbing issue?

no. Occasionally I would get a tiny 1 second rub on the top of the fender in the rears on dips.

I have the same problem. I lowered the car on BC coilovers and I have also done 3 aligmment and wheel balancing, still had the problem 20mph+ then the shaking goes away. I have had it dropped for about a year or so I have had to change my CV boots. Other ppl on the forums had this problem aswell.

I dont know if this can cause shaking but did you install shock/struts to? You cant just put lowering springs on with stock shocks/struts. You will blow them out in no time.

No one has been able to yet. Its more like luck of the draw.. Some get the vibrations and some dont. If I got them, id probably have sold my car for a 350 or F by now.
