Doing a 68 frame off resto, trying to decide on suspension upgrade or just revamp stock? Seems like revamping stock is still going to run around 1500-2k with bearings everything all new! I have studied these for a while I'm sick of looking!! Advice wanted stock vs aftermarket upgrade and what aftermarket kit? Thanks

 

If your '68 is going to be a daily driver I would go back with stock parts.

 

What kind of aftermarket, Ridetech, Speeddirect, VanSteel?

 

I take it your car will be mainly used for weekend cruises and some light spirited driving since you are currently looking at restoring the suspension with factory replacement components. With that in mind, I would recommend using good quality rubber bushing, ball joints, rod ends, etc. from MOOG. Something I highly recommend before diving into the suspension of one of these cars, especially if you are going to start modifying it is read this article: http://www.corvettefaq.com/c3/vip.pdf

There are a few upgrades you can do to improve the handling and steering without resorting to poly bushings, which will increase NVH.

Sway Bars
Front sway bar - stock
Rear sway bar - none (or factory 7/16" matched to a 1 1/8" front)

Steering
Steering box - adjust the gears and shim the gears (Lash Adjuster Shim 4 Pieces 6800114 22.50 from Doctor Rebuild) http://www.docrebuild.com/dr-r-web/PS2.pdf

Idler arm - Use a high quality unit (very important for steering response and stability of front end)

Install some anti-bumpsteer blocks if you don't mind lowering the front suspension some.

Replace the bushings that locate the rear differential crossmember. These are essentially part of the suspension and affect rear toe if they are in bad condition.

Along with adding these bushing "supports"

Reduce rear camber change by using a new camber bracket such as this. The rear camber curve was designed for bias ply tires and radials don't need as much camber gain. This will also reduce the jacking affect of the rear end, which is also a good thing. You'll need to use some adjustable strut rods with a bracket like this.

If you're rebuilding front and rear for less than 2k, you are doing very well. Especially considering you said "everything new". I spent over $200 just for new nuts, bolts, and washers for the rear alone. I assume you are rebuilding TA's and diff yourself?

 

TRZ control arms up front , Borgeson steering box , moog springs . Keep center link and sway bar replace everything else.

Composite our back .

 

I have rear vb&p spring kit and smart struts and bilstiens i cant use. Decided to go with different set up due to hp. Pm me if interested.
