How far past level is it prudent to lower the LCA angle when lowering a Miata?

Here is where I am now:

Would another inch of lowering be too much? Not a track car, just a cruiser.

What's your hub/fender measurement?

Eyeballing my stock height NB has the LCA slightly lower (to the ground, meaning it slopes downward from the inner pivot) at the knuckle than what you show there. My car looks like a 4x4 too, so you're probably fine.

Just move the floor up another inch , or two and you'll be fine. It's not welded in place yet, is it?

Unconventional.

Oh. Right.

You can definitely go lower for a cruiser.

Ride height looks pretty nice there...

Shoot for the lower arms to be horizontal, from inside pivot to outside pivot. This will minimize scrub and weird roll center movement/location.

That's a great rule of thumb, but it does't really work on a Miata. That's basically stock ride height or higher

Picture looks fine to me, it's probably where almost every fast street Miata sits.

Yeah, but it's not actually a Miata. Since he's "making it fit," lets shoot for "great rule of thumb" and move the entire subframe up or down to get the "look" you want.

Moving the sub-frame (entire Miata chassis is under the Volvo) any further up is not a trivial thing past this point. I got the pinch-welds at the bottom of the rockers to align but any more will require some creative use of metal cutting power tools on the A post of both the Volvo and the Miata.

Based on the feedback I am getting on this board and the build thread forum, I think I am good to leave things as they are.

Cool. I think it looks great just the way you have it.

Level LCA's at ride height are ideal, you can fudge a couple of degrees if you must but the ideal is to keep them level.

You'll need to log in to post.
