Has anybody used Heidt’s or TCI’s (or anyone else’s) bolt in 4-link rear suspension or the IFS front-end sub-frames? I’ve got a 67 Camaro (drum brakes & power steering) with totally worn out suspension (170,000 miles on original).

I’m about to do a major upgrade and refinish to the entire car, and will probably be dropping a few $$$ into this car’s finishes. I’m just wondering if the ride and handling performance will be worth the expense of these suspension replacement/upgrades. Or, should I just replace the existing springs and rebuild the original suspension?

Thanks for any advice.
