will I need to install the SPC toe bolts if I use the SPC rear camber arms to reduce negative camber? I am currently on stock springs and 19x10.5 +12 wheels on the rear and my camber is at -2.1

This is on an '06 6MT coupe with RAS

The main reason I'm asking is I would like to avoid having to dremel in order to fit the SPC toe kit

 

anyone?

 

All depends on your toe, what your specs on that... The camber kit will fix the camber but toe will eat your tires

 

my toe right now is within spec: left at 0.10 and and right side at 0.14

just my camber is way off at -2.1 :/

 

Pretend you have a pair of roller skates on. Zero toe would be when your feet are completely straight and you roll quite easily. When you point your toes inward (pigeon toed) you have toe in. You can imagine how your roller skate wheels would wear out significantly faster if you forced them to roll forward while they're basically pointed inward (sideways). That's why you need toe bolts; to get your toe as close to 0 as possible, and stock toe bolts dont have enough adjustment if youre lowered. Toe and camber are completely different.

 

No you don't need them, just the arms should get you enough adjustment to get back into spec.

I'm lowered 3/4" and was at -2.2 degrees, with only the rear arms, they were able to get me to around -1.8(or -1.9) deg. Basically with the toe bolts they could get more positive camber, but my tire wear is just fine right now.

The way these cars are set up, adjusting the camber changes the toe setting. Too much camber adjustment will mean the stock toe bolts won't be able to compensate.

At -2.1 you're not too far out of spec. Try with just the arms and see what your alignment guy can do.

 

That's strange, I was at -1.4 and my toe was out of spec and my rear is only dropped .8"

You definitely need toe bolts. It's the most important part.

 

I agree. Toe Bolts are necessary...
