The main problem is every time you adjust height, it changes the camber and toe.
When you adjust your toe, it changes the camber.
When you adjust your camber, it changes your toe.
Realistically getting your toe to zero (what you want) is nearly impossible. You can try to eyeball it or measure the distance between the front of the wheels vs the rear of the wheels (front of tire then back of tire) and equalizing this distance but in the end, a shop is the only place that can really make the magic happen. I've been looking at a lifetime alignment from a shop that allows custom alignment specs but am not sure whether its a real lifetime alignment or only for that set of tires, tires purchased form them, etc.
Anyone happen to know more about this? lol

Tilt: honestly i could probably tell you more names of shops that WON'T let you do custom specs. Kinda sucks. I know what you're saying about the camber n' toe - i'm sure i'll never get it perfect but i'm not scared of trial n' error at this point.

Matt,
You should just wait and wait for the local Miata tech day that one of the members hosts about 3-4 times a year - Garage Woolery: http://garagewoolery.com/
I'll take you when they have the next one. They have a fender roller, alignment tools, and also even scales for corner weighting (all items I'm sure you do ALOT considering how many wheels you go through). A lot of those guys over there have set up cars on a regular basis for a variety of driving activities.

Paris - yeah, I'm almost tempted to get a part time at a tire shop simply to use the equipment, LOL!
I'd love to check it out with you Eddie, the na miata group sure seems like a tight knit family!
What type of tools can be used for a self align? I can't think of anything that can adjust toe aside from crude measurements or expensive machines, lol.
edit:
Holy cow, I knew something like this existed, now to research and figure out if it can be applicable. I'll order tonight! lol

Depends what your idea of crude measurements are. You can buy kits that can do it from something simple as a string type to optical laser types. Back in my racing days we just simple used a measuring tape (need at least 2 people obviously) and measured from center of the tires in both front and behind.
I think you could easily get accuracy doing that at least up to 1/16" of an inch. Just takes 2 people to do that. Outside of that for more analage measurements, take it to a shop. I plan on getting a tool for measuring the camber when I drop and set it on the new tires and something rough to get the toe until 1-2k miles are broken in on the new suspension. Afterwards, I'll take it to a shop to get corner alignment for a full balance.

Anyways, I'll talk to you guys later. Back into hibernation

it will be interesting. This is what the +22 is looking like just put on the car.
Oh more fender rolling....
For tires, it between the Khumo V710 or, most likely the Nitto NT01.
255/40/17 but now that I looked last night maybe 245/40/17 since it will have a minor stretch that i can use to help lower the car more aggressively.
Thoughts?

remember the 255's will have a bit of a stretch (not much) but with rolled fenders it should sit in there real nicely. Or, if you want complete piece of mind, get the 245's. Im getting 18x9.5 +22 w/ 255/35 for my next setup and Ive done a ton of measuring on my car to see how it would fit.

I don't consider 255's to be stretched unless you've got super stiff, square shoulders on the tires. I've got at least 3 different brands of 255's at home ranging from nexen to pirelli and upon measuring all of them a few days ago, the faces of the tires are just about at 10".
TH - Like J said, our suspension by nature has plenty of travel and cambers up significantly. The fit will be fine :D For maximum mechanical grip, better feedback/response, a tad bit of gearing, and a more "for sure" fit, the 245/40/17 would be your prime choice; Unless it were autocrossing, I'd personally opt for that option. It's not like 18" sizing where a 245 is typically a taller tire than a 255, thus negating some of those benefits.
Vlaze, that sounds like a really good mixture between functionality and this 'aggressive' bullshit so many are coming to like. Same poke as a 9.5 +22 but with the outermost shoulder pulled in a bit - that'll be great
edit:
Mike - I saw your post in the post pics of your ride thread, I thought we were going to need another month or two?
edit2: I looked through my photos and this was as close as I could find:

^Yea, not only that but it should fix my speedometer issue where even with stock tires/rims I'm around 2mph under what's on the gauge according to radars at 30 mph. This should fix that and bump it to almost even dead on from what I've read.

You don't need to pay me, you just need to catch me when I have some free time lol. If your fenders aren't rolled I know someone that will rent a roller for super cheap for you, just let me know.

By law manufacturers are allowed a 2mph +/- variance with speedometers. Some thing that they maximize this by that 2mph to help prevent lawsuits as well as shorten the life of warranty. I know mine was off by 2mph back in the day, but for what reason I don't know.

Yeup, but it works out to our benefit. Because of factors like this, and different wheel/tire sizes, radar accuracy, so forth is what gives us breathing room when going over the speed limit. I find it works well up to a 7-8 mph over the limit criteria for 95% of places I've been to. Course some areas I've seen cops blow by me when I'm going 10 over. But those factors are what allows us to go a bit over the limit.

I think for those of us who are still trying to catch up on what's going on it would be a good idea to pick up the newest Super Street magazine; April 2010.
It brushes up on obtaining the correct fitment and emphasizes on the basics. Terms, procedures and common tasks are all included. Def a good read for those looking to get into it but don't know the basics.
Good job superstreet.
