So after going to enough track days to properly drive and stuff, I'm realizing I need more camber on my tires (i have a lot of wear on the outsides of the tires). I took it to an alignment shop and asked for the m.net recommended specs. The guy said that he maxed out the negative camber at 1 degree on left and less than that on right.
I have a NB1 with stock suspension. Is this guy crappy or is there a chance that my eccentric bolts are broken or control arms are bent? Same problem with rears. I'm kind of doubting its either since all of them can't get below 1 degree
I read somewhere that lowering the car about an inch will help get more camber but I don't think I know enough about this
thanks

 

Wear on the outside usually indicates a toe issue. Post your original settings. Also, how old is your suspension?

 

Toe will generally generate a swiped wear on one side. If it's just excessive wear, it is indeed camber.

You can indeed increase camber by lowering. With stock suspension you're not going to get much camber out of it. As the car lowers, the way the suspension is designed will generate more camber.

 

Ill take a picture of it tonight. Tire wear is mostly from the track and I haev slight toe out on the fronts, thats why Im thinking its camber since the tires are folding over.

I was planning on getting a new suspension regardless since i have 110K on stock suspension with about 1k track miles

 

Don't bother with the m.net alignment. I'm running a modified version of it right now from Miata Alignment Specs. Compared to a stock alignment it's night and day different in handling, but extensive testing has shown that these cars want more front camber than rear. As soon as I get my poly bushings installed on my NB control arms and uprights I'm going to be swapping to a full NB drivetrain in my NA, and I will be going to Emilio's dual duty alignment. Miata Race alignment

FWIW, the first alignment has given me good even tire wear with regular cross rotations. I don't know if I drive hard enough to get the same with Emilio's alignment, but I can't wait to try.

Also, as to alignment shops. If they hassle you about your own specs, leave. A good alignment shop will charge you for a performance alignment. This isn't the standard $59.99 warranty alignment.

 

Have you ever done your own alignments? I'm the kind of person who likes to do things on my own.
Was thinking of just doing my own alignments and going to a shop to have them measure it. I think I have one of those lifetime alignments from Firestone.

 

I do my own alignments. On a John Bean computer alignment machine. The lifetime alignment only applies to a stock alignment. You don't want a stock alignment. If you have a 50 year + shade tree alignment guy to show you how to set it up with tape and strings and a plumbob, you can, but you'll have to pay the shop doing the work full price whether he adjusts one parameter, or all of them.

Just get a professional computer alignment. It's much easier on you and your tires, but maybe not your wallet. Depending on the shop you'll pay between $100 and $150.
