Improving Ride on a Daily Driver 1970 Cutlass
I said it daily driver! I drive my 1970 Cutlass 30 minutes to work about 2-3 days a week in the summer. It is bone stock and it definitely needs new shocks. Steering is very floaty, so of course would like to see that a little tighter. My budget is $1500-4k installed. I'd like to just tighten the ride up a little on the commute, which is 30 minutes each way (mix of highway and side roads). Any suggestions on what I should be doing? Any packages you would recommend off the shelf? I will be bringing it to a mechanic for the work. I am assuming he will have some recommendations but I wanted to do a little research before hand.
Car is a 1970 Cutlass convertible, 350, 4 Speed in great shape.
This seemed like an option. http://m.bmrsuspension.com/?page=products&productid=77

I drive mine to work all the time and the suspension / steering is all factory or factory equivalent and it's firm and tight.
- New springs all around. Spring specs depend upon what ride height, stance, and firmness level you are looking for.
- New modern gas shock absorbers front and rear.
- New suspension bushings front and rear.
- Ensure inner/outer tie rod ends, center link, and idler arm are in good shape. If not, replace with new parts.
- Ensure ball joints are in good shape. If not, replace with new parts.

^^^THIS! The biggest steering feel difference between older cars and newer ones is from the caster setting. Of course, be sure your front suspension is in good shape first. I would not swap springs unless you think they are sagging. Stiff springs make for an uncomfortable ride and can cause the tires to lose contact with the pavement over bumps - and at that point you have no handling. I like KYB shocks. Also, get the biggest REAR sway bar you can find. The A-body is an understeering pig from the factory. All things being equal, the stiffer end of the car breaks away first. That means you want to make the rear suspension stiffer to make the car more neutral. Herb Adams used to use a 1.5" rear bar on these cars.

My .02:
Shocks - Bilstein
Suspension Parts - MOOG
Springs - Eaton
Use rubber on the control arms, and poly on the front sway bar links and bushings
Radial tires with a pressure of 30 PSI
Be sure that your front wheel bearings are good as well.

There is a guy on the Oldsmobile 442 W30 & Hurst Olds Fan Club of Facebook page out of CA that rebuilds stock units for quicker ratio. I haven't used him but people speak highly of him. One thing is you'll want to locate a core so you have the new box in hand when they take the car apart.
Wheels & tires can make a big difference depending what you are running now. A good radial tire on your stock 14" wheel helps a lot if you want to keep it original looking.
I went with a set of 17's with General tires and it made some difference. If you are a smart shopper you can be all-in for about $1K-$1250
