wheel offset
 

lookin at konig lightspeed 15x7.5 +32 offset with 205 -50-15 on a stock height miata(na).will this set up look ok and not rub? i dont want the wheels to be obviously out passed the fender line too far

I think that you will want more rubber than that if you are going with a V-8.

yes you are probably right but i,m kinda hung up on keeping unsprung wheel weight down so not to mess up handling. i,m not going to be drag racing.i,m done with that ,selling my 89 5.0 gt for cash for the miata. (5.0 twisted wedge F cam ,street heat,42lb,twin turbo,320 rwhp@5psi when msd digital 6 gave up the ghost, still have,nt got back on the rollers

There is a lot of wheel info here: http://www.miata.net/faq/wheel_weights.html

I am pretty sure that wheel comes in a 36mm offset. To answer your question, yes it will fit with that tire size.
The unsprung weight benefit is not worth the lack of traction 225 min. tread width, and you will still burn 'em up! ;-)

I'd go with at lest a 225/45-15. Hankook makes one in their RS-3 line. That size tire on a 15x9 offset 36 is ideal (may require a little fender rolling in the rear), that size on a 15x8 +36 is good also.
