I was using the Hib Halverson chart as a reference.

My info was based on the Corvette Black Book for the C4s.

88-91 Z51/Z07 front and rear spring rates are all the same. In 92 the font spring dropped from 115.5 to 90.1 and it stayed that way through 95. In 90 and 91 sway bars were 30/26 vs 30/24 in 88-89 and 92-95. http://www.corvetteactioncenter.com/...usp_chart.html

Just because it's on the internet doesn't mean it's correct....

The ONLY year that the 26mm rear bar was available in the Z07 package was 1991 and as a result of that those cars handled terribly. The 1990 Z51 rear bar was a 24mm. The tuning mistake was made when they went to the Z07 package in 1991 and it was quickly corrected for 1992.

Hib's chart in the Corvette action center is not correct. He corrected it in 2002, but there are still copies of the original one (from 1996) with that error in it floating around....

Here's a link to the revised chart...

I stand corrected oh wise Solo! You need to come to NCM in the Spring for a HPDE. And Ruby too!

To the OP, I just got word that Banski has everything 20% in his inventory. Even if you don't install them now it would be a good time to pick up the parts.

A lot of the folks here may not remember the Roger Johnson C4 we keep talking about. Here's an article I wrote about Roger.
