Lowered is200 upper arm hitting

SLBIS200 · August 16, 2023

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.

I dont know about the part you're referring to, but bear in mind you'll probably need to inform your insurer of the modification. Might be worth checking in advance if and how much they'll bump the cost.

Yeh they already know of all plans with my car. I just wanted to solve an issue before I put any parts on the car as I know a couple mates with the same issue. And would like to avoid hitting the upper arm.

Thank you tho mate

It depends on “how low” you’re planning on going as generally the tyres will hit the wheel arch liners first.

I would think the guy is referring to “bump stops” to limit the upward travel of the upper control arms but these will cause the suspension to bottom out.

The ultimate mod must be as shown below with the lowered LS400s across the pond, but I wouldn’t go this far.
