Diff gear recommendations

4spdragtop said
Hey all, I'm contemplating a diff gear change from our factory 323 to 355.
I'm not looking for top of the line, but want quality and NA made, if possible. Next to zero track time(once for the bucket list)
Mfg recommendations??
Thanks
Steve

I don't think a 1/4 of a ratio is gonna make a huge difference in acceleration for the time, effort and $$$. It's like going from 29" tires to 26".
