So i was plannin on buyin a motordyne spacer.. but i didnt realize there was so many damn choices.. whats the difference between these and what one would u recommend for me if im gettin the turbonetics kit???

Basic 5/16"
Basic 1/2"
Iso thermal 5/16"
Iso thermal 1/2"
copper iso 5/16"
copper iso 1/12"
mrev iso copper 1/12"
mrev iso thermal 5/16"

 

If you have stock strutbar: 5/16th copper ISO
If you dont have any strutbar: copper iso 1/2

If you have track model + strutbar: mrev 5/16th copper
If you have track model and no strutbar: mrev 1/2 copper

 

I was looking at the motordyne website and saw that all their spacers were for "off road use only". I thought they were all street legal.

 

did you mean the 05+ track only?

i have an 03 track, i wouldn't get the mrev correct?
