Default for those only lowered on springs

so long story short I had to get new front tires installed today...also alignment because im lowered with swift springs in the fronts only....my old tires were 255/35/19 and the inside wear was pretty nasty on the left front.

shop calls me and says that I am going to need camber arms and toe's? n the front only because of the negative camber....

my new tires are 235/35/19...

for those of you who have a similar set up did you have to get camber arms? Any mods needed on just a lower for the front?

thanks,

Have you already upgraded your front LCA bushings to the RR Racing or FIGS? I'm lowered on Penske coilovers, with no other mods to the front suspension other than LCA bushings. I'm getting pretty nice tire wear on my current set of 255/35 Michelin PSS, and that's with four track days & near daily driving since August.

Yes, it definitely should help minimize inner tire wear, and perhaps eliminate it entirely. Additional benefits are an improvement in steering feel & stability under braking. I don't think anyone on this forum will argue that it's not a worthy upgrade. If I were you, I'd start with that before replacing any other suspension components.

Was the alignment checked at the same time the front lowering springs were installed?

+1 for the LCA bushings! There is a video and a good read thread on here about the topic you just have to search for it. It's amazing how much the stock bushings move under a load.

I didn't need any additional mods with Swifts in the front only.

My car aligned within spec, and the tires wore fine.
