I put the complete VB&P Performance Plus System on my 79 and the offset trailing arms, front shock tower brace, new stainless steel brakes,and 17 x 9.5 Gransport wheels with 275x40x17" tires. There is more than a night and day difference in the car.
Have a built Binford small block more power!!!
I have ran the car in many auto cross events and have always won my class.

Thing is, that can be like opening Pandora's box if you aren't certain what you're getting into, which shows the OP's wisdom for asking before doing.
Also, IMHO the front shock tower spreader bar ought to be added to every C3 handling enthusiast's do list, as stiffening the chassis is always a good call.

With the heavier springs, the spreader bar does make a difference.

It was a huge difference. Before I had to wait for the front end to set up as I first hit the corner. This was just a fraction of a second. After I put in the brace it was a HUGE difference. It stuck right away did not have any delay and it felt like the car was saying GIVE ME MORE.

i just picked up the VBP GT+ kit (460# coils, 330# rear mono spring, 1.125" front sway, 3/4" rear sway, smart strut, bilstein sports)
should i just leave the rear sway bar off, or should i slap it on? the last thing i need is a car thats so prone to over steer that i spin it around with out trying.

Check the threads, there was just a very recent thread here about this very subject "Rear sway bar sizes" or something like that. Plenty of suggestions & opinions.

Are you saying you need a 3/4" bar with the package listed above?

Yes, with the package I have. By the way if your car was yellow with a black stripe it would look like mine. I also have the Lemans Headlamps.
I have been running auto cross events since the 70's with various Corvettes.
The VBP kits are well balanced that take alot of guess work out of what may work. The kit I have now in my 79 handles better than my 68 B production Corvette Race Car which I ran in TriState and Midwest Council in 1973-74-75-76-77.
The last event that was held at Bennet Raceway I ran a faster time with my 79, than I did in the 70's with my full race 68.
I choise the advanced kit since I mainly wanted to have fun at track events and autocross. I did not care about the street ride. HOWEVER it rides much better on the street than the stock set up.

I got mine from Vette Brakes and Products. If you're running an electric fan it's a no-brainer. If you have an engine driven fan then some welding is required.
There may be other vendors that sell one as well, but I like VBP's.

When I first started building my '73 and knew absolutely nothing about the car, I, too, put on the same exact kit from VBP. Poly bushings, smart struts, cross brace, etc. The car was absolutely evil on an autocross course. It wanted to swap ends constantly. The 3/4" rear bar came off and the car improved immensely. Many changes have been made since those days, but there never has been a need for that big rear bar. It's evil....possessed!!!
Now I have 9.5 x 17 with 275 x 40 x 17.
I won every auto cross entered, and have taken several FTD
The rear bar is a must. Why would GM include it with the f41 upgrade?
Here in the Midwest area almost all set up C3 have a rear bar
