So I am in the market for the BC Racing coils for my '07 AWD IS250 and after reading this thread and three others I am trying to make sure I get the most out of my setup. So far what I hear is that axle spacers and possibly RCA blocks help to prevent the wobble/shake at low speeds?

Can anyone who has done this testify to them working??? I am wondering if anyone has both coils and RCA blocks and if it solved your issue. Thanks guys!!

AWD members lowered on RCAs didnt report wobbles or vibrations. I had great success with just my spacers but others say they did not

so a friend of mine just made a plate that raises the engine by placing it in between the motor mount that raises the axle back into position. says he has very minimal to no vibrations.

now, is this the same as getting RCA blocks placed on your wheels raising or keeping the axle alignment with the trans?

so far he doesn't have any complaints.

so the blocks help keep the level of the axles the same. cool

Its either this or RCA blocks. I saw some people lowered with RCA had complaints but i guess it also depends on how low you plan on going. I just want mine with at least just a finger gap or less. i hope that doesn't cause to much vibrations with RCA blocks or if i go the plate route.
