I'm about to lower my is200 (04) with some hsds coilovers and was speaking to someone at caffine and machine this Tuesday night and they mentioned something that I should buy that will stop the upper arms from hitting the top mount or body when I lower it. He mentioned it was only like £100 or something like wise. Anyone know what this is. I for some reason didn't make note or remember the dude. Anyone know. Idk if its RCAs or like modded spindles.
