New track shoes for the Miata. I cannot wait to try them out at Texas World Speedway in a couple of months racing against some fast TTS competition.
Cue the **** music...
They will be going on 15x9 6ULs.

They worked awesome on my car. Make sure to start with at least 3 degrees in the front and 2.5 in the rear of camber. I found tire pressures of 26-28 hot to be ideal. Rotate midway through the day for best life. Don't head out with pressures to low or you will cord the outsides. It's best to start around 25 and bleed down midway through the session.
Enjoy!
Enjoy!

Funny thing is, when I was using the Formula Atlantic Hoosier slicks last month, which are essentially the same size, and radials, the tire temperatures (probe type) were showing that the camber was OK. They were slightly warmer on the inside edge. However my hot pressures were a lot higher than 28 psi since I was desperately trying to get heat in them by adding more pressure. It was a cool, cloudy day and the track was cold.
I should call Hoosier. I want this to be right so I do not cord the edges.

I am camber challenged right now in the front. It is maxed out at about 2 degs. It might be time for some offset bushings or a V8R lower control arm.

I suggest you wait till you can get more camber in the car before trying them otherwise it will be a short love affair.

I have a non-stock K-member with the V8 swap. But I also had problems getting more than about -2.2 degs camber on my stock k-member 99 (lowered) as well. There was nothing bent on that car. This seems to be a common limit no?

Definitely not a common limit, no. My black car is capable of ~3.4*, the red car is capable of at least that much. Both cars are set at 4/4.2 ride height, front camber on both is at 3.0*. Adjusters are not maxed out.
I am going to start at 3.4/3.0 on the R80s and see what that gets me.

Moving the lower ball joint is another option (lower OEM parts cost too).
1 degree change is about 10mm difference top-bottom of tire.
Moving the upper ball-joint (to get that extra degree camber) will move the top 6.8mm
Moving the bottom result in 3mm move.
So a net difference of 3.8mm more inwards by modding the upper, but a 15x10 is probably tight however you look at it.
The difference might be different (larger or smaller) when looking at frame contact at full (if used?) lock.

Full lock clearance with a 15x10 is a pipe dream. I would expect it to rub half a dozen things at full lock - the front bumper, the FSB, the UCA, your mom's ****, etc. We're looking for shock tower and fender clearance - the shock tower is very tight with the 10s. If I can compress to the bump stop and sweep the steering wheel 270* in either direction, then in my book it fits.
