One corner of my Miata is too low

And I'm not sure why.

This is my $500 90 Miata. It came with some crappy lowering springs and Tokico HP shocks. I think the springs are Tokico brand, too. I don't see any bumpstops on the front at all. The icy hot stunna who had the car before me wasn't a fan of quality work, from what I have learned.

The car is lowered significantly, but the left front is noticeably lower than the right front. I had previously attributed this as a visual flaw only, as the left front fender is tweaked and a bit of a mess.

This was never a problem with the stock wheels, and even when I put on some 15" Falken Hanabis with 205/50's it would rub ONLY when under heavy bumpload.

The other day I put a set of 195/55 15 snow tires on it from an old Civic, and now, whenever I make a right turn of any significance, the LF wheel rubs in the wheel well. I looked at the wear marks and it looks like it is rubbing all along the top of the wheel well, both on the plastic and the metal inner fender.

What could be causing this one corner of the car to be too low? Crappy lowering springs sagged in one corner? Tweaked chassis? Invisible fat guy sitting on the fender all the time?

Level the chassis and take fender height measurements? That should rule out a tweaked chassis if they all come out equally.

Since you said it has lowering springs already on it, they could be installed incorrectly and keeping the one side HIGHER then the other.

When we got our '93, it was a theft recovery. It had been taken for a joy-ride and run up under something (I'm guessing a guard rail). It wasn't that obvious, but one of those where you would stand behind it and go "huh...that's just not right". It tracked perfectly, but clearly the damaged side was a bit lower. After putting it on a lift and looking back and forth at the undamaged side comparing it to the damaged side, I finally figured out it was the lower control arm. Went and bought a used one and guess what?...it was bent, too. Finally got a good one and all is well.

Crappy lowering springs often mean the car's sitting on the bumpstops all the time. If you have different length bumpstops, it'll sit crooked. Measure the ride height at the pinch welds under the doors to get a true idea of how it sits.

Broken spring ?
