Now before i get someone preaching the rules. This is for my turbo AutoX miata. For my SPEC miata I already installed the offsets thanks to Ron here which gave me awesome advice...... ANYWAYS this is about not buying another pair of Offsets for my Daily/Autox miata and instead attempting to modify the eccentric bolts to gain more camber and/or caster. This is a 92 with bilsteins/ custom springs(500/350) /racing beat sways  setup. I know this isnt exactly about SM but i figured you guys know so much that you could help me! :)

 

My current alignment specs for my car (I could get more in the rear but don't want any more)

 

Front Toe: -1/16

FL: -1.9 caster: +3.5

FR: -1.8 caster: +3.5

RL: -2.8

RR: -2.8

Rear Toe: +1/32

 

My goal for alignment is to raise the front camber to 3 but have enough leeway to get up to 3.5 so i don't have to run +1.0 caster. I really just want to experiment since the rules don't require me to buy offsets or bend my spindles (not to bring an elephant into the room). If worst comes to worst ill make another set of offsets.

 

My questions are:

 

How would I go about "grinding" these down?

Would this give me sufficient camber?

Would grinding them down cause the suspension to un-align itself faster?

Have you installed the 99+ shock hats and FatCat shock bushings?

 

Are you asking about grinding the alignment cams? Wouldn't that decrease the amount of camber adjustment?

Maybe, I dont know much about alignment im justing trying to somehow get more camber with my rotary tool and grinder. Ive heard from my friends uncles brothers sisters boyfriends newphews grandsons aunts cousins friends colleague that you can somehow grind down something in the suspension to get more camber.

You could scribe a line on the cam and file to the line. Before messing with the cams you may want to check and see if the slot in the sub-frame will allow more travel inward.

Maybe if you gave me a nice microsoft paint drawing. I dont know anything about suspension besides replacing bushings and installing coilovers.

^ I was talking with my head up my a$$. ^ This would be if there were cam bolts where the upper long bolt is.

 

The lower cam bolt needs to move outward to get more negative camber. The upper long bolt would need to move inward to get more negative camber.

 

Your friends suggestions may be to grind the slots longer outward in the lower sub-frame. BUT then the cam would not be supported on it's back side and could slid inward and you'd loose your negative camber.
