does anyone know of any kits or anybody done any custom jobs in order to have negative front camber? all i have found is the SPC kit for the IS250, but i want something that will allow me the most negative camber possible

 

Yes the negative upper arms for the isx50 and the is300 will work. I think Megan and Topspeed are the two brands I recall that offered them. I had tested a set out if you search and had them for sale in the 3 gen classifieds and sold them to another member.

 

if u want max negative camber u need more than just the upper arms u need a shorter front arm aswell

The 3GS can use the same parts as the 18 crown

 

those shorter knuckles/arms are the answer to riding low. it will prevent the upper A-arm from slamming into the shock tower when you hit bumps.

Im going to cut mine as well.

 

I dropped my car slightly using the F-Sport Springs (est. 1") and after about 1.5 years noticed it wearing the inside of driver side tire. Fixing/adjusting the camber will help/fix this but is it even worth it, or should i just face the facts that it won't wear evenly. 1.5 years (20k miles) is a lot better than I thought I would get anyways.
