I've got the Mugen Control arms, i've not had a chance to use these yet.
Here is the blurb from the Kings MS site.
The Mugen front lower control arms are manufactured specifically for the US market RSX and– bolt-on installation with no modification required. They are constructed of lightweight aluminum alloy and reduce total unsprung weight by 10 lbs (5 lbs per side). Utilizing Mugen hard rubber bushings, which are 120% stiffer than stock, the arms dramatically improve the consistency of the suspension geometry while under load. “Toe steer†during cornering and dynamic toe changes under acceleration and braking are reduced significantly. Requires the use of a JDM front sway bar or the Mugen DC5 front sway bar.
