I have a 97 Miata which I will be installing Mazdaspeed Miata brakes on (calipers, carriers, etc). Which kit should I buy, the one for the MSM or the 90-2001 Miata?
The Mazdaspeed brakes (which uses sport rotors that are bigger than the standard) will need the Sport brake lines as they need the extra inch of line to supply the now higher caliper level. So, the Sport Lines are needed for your swap. You can find these lines here: http://5xracing.com/i-6764565-techna-fit-stainless-steel-brake-line-kit-for-2001-2005-mazda-miata-mx-5.html
