Hi. I have an early 90 base model Miata w/ OEM hardtop that I am contemplating building to SM specs. Car is completely straight and in good overall condition (other than paint). There is some rust on the rocker panels (under the doors). I'm trying to determine if its too much rust to bother fixing and building a race car out of.

Anyone have any thoughts or pictures that can serve as examples to guide me in determining if this is worth it?

I'd post pics but the car inaccessible right now.

Thanks.

Also, any thoughts on how much it would cost to repair/replace the rockers would be good to know.

Thanks.

Alberto.
Are we talking rust holes or surface corrosion? Also, the fact that it has a hard top can mitigate in favor of buying it no matter how bad the rust at the right price.

You can always part it out and keep the top if it's really cheap (like $1,200 or less).

Look in the trunk under the carpet for cancer too. It can get pretty bad under there and you don't want your battery coming loose. I've seen amazing things done with rust buckets but you want to know what you're in for up front.

Some small holes. Most of it seems like surface corrosion.

Is it that expensive to cut and replace the rockers that you'd consider not going forward with it?

The trunk is fine. No rust there.

you kidding me, rust holes in a early 90's that will just make it easier to come in on weight. I'm thinking of dipping mine in salt water for a while

NY / Long Island

The rust came about from being stored/parked outside sitting in snow over the last couple of winters.

Rust on the rocker isn't uncommon on these cars. The drain for the soft top goes through there and they get plugged up sometimes and you get some rust. My donor had that issue and a little bit of fab, welding, bondo, etc fixed it and never been an issue since.

You can do a search on Miata.net for more info on the issue.

Yep. That was one of the causes of the problem. I'll search on Miata.net. Didn't even think of that. I'm not on that forum much.

How much did it cost to fix?

Nothing really, just a little bit of effort on my part and a few supplies.

Rocker panel repair patches are available from BTDT racing. I am sure Blake will chime in soon
