Default 1990 Corvette | Rear Toe Rod Makers?

Question: Does anyone know of manufacturers of C4 rear toe rod kits/assemblies (other than Summit)?

Situation: Need to replace rear outer tie/toe rods.
- The supply of REAR tie rods is strangely limited (they're out there, but much more difficult to find than steering tie rods).
- Considering splurging and replacing the entire rear toe rod unit with something like this (from Summit), but am open to other options:

Thank you!

I would suggest the after dark unit. Great customer service.

nothing, that’s a Van Steel Corvette part, it’s a decent option. However, if you get an aftermarket lower strut rod or camber rod bracket like ADS where you lower the inboard rod attach bolts, you may wish to get the After Dark Speed or EM because you can adjust the angle to reset bump steer.

You can adjust Bump on the Van Steel ones, but I doubt most will go through the trouble of doing this. To the OP, the factory GM one has been discontinued for about 10 maybe even more years. Zip had the last 25 of them and they may have been gone longer than 10 years.

I see the center adjustment in the description, didn't see it in the pictures. Yeah, just an outer bump steer adjustment would be inadequate with aftermarket/adjustable inner strut rod brackets.

If someone messes with the geometry where the three rear links in front view no longer intersect, they better adjust bump steer.
