Beating my head about what suspension Ride tech, speed tech, heidts

[97 Z Me Go]

As quick as I can, I am doing a 68 nova 4 door. ls/6l90 auto car with a tvs 2300. I have all that im down to suspension.

I want the tubular control arms will need some rear suspension. plan on 8.5 or 12 bolt. Is it worth the power rack and pinion or just upgrade the steering box?

Why does no one seem to use Heidts on here or on pro-touring.com? I see they do have everything i would like. Ridetech doesnt have a frame. Speedtech has everything also.

Guess one big question is...The heidts stuff not strong,fit correct,to cheap?

Do you keep the stock frame?

Do you need power steering rack and pinion?

I plan on having fun with the car im not a autocrosser i more or less want the look and feel of a "new" car on this 68. I dont need the best of the best but dont want to get something that is going to fall apart or not fit correctly

Thanks
Kyle
