What Wheel Offset Can I Get Away With On 1997 Mx5

You should just get away with 15 x 7 or 15 x 8 et15, it's considered to be around the limit before you have to roll the arches or add extra camber. You may have to pull the liners depending on how low you go!

if you go low enough for them to look good you will need to roll the arches

ok thanks think il lower it first before i start buying wheels with different offsets then take it from there.
