Rear end questions
I was reading on the .net about rear ends. A post said 99'-00' cars (non 6-speed) came with a 4.30 rear end. Is this true? Would the rear end be as strong as the torsen? I have no complaints of the 1.6 ratios, I just dont wanna blow it up.

if its a 7'' rearend its stronger than the 6''. 7'' rears are in 1.8 cars (open or lsd) and 6'' are in 1.6 cars (vlsd/mazdaspeed ect) Remeber the diff itself is not the weak part, its the ring and pinion gears that go.

But do the 99'-00' cars have the 7" with a 4.30 ratio? After reading about 30 threads about rear ends I couldn't find the answer. But I do know about what fails, what years have what. Pretty much everything but the one thing I want to know, go figure

I rarely drive on the freeway, maybe once a month at most. So I have no complaints with the 4.30. I just want a 1.8 dif to handle the power. But the few times I was on the freeway I agree, those extra 200 rpm's would be nice.

YES! Its confirmed that the 99'-00' difs are 7" torsen with a 4.30 rear end. Looks like I need to find one now. I have only seen one miata in the junkyard. It had caught on fire and had no useable parts....I need to find one.
