Phast Phrank

Phast 6
I drive a 90 Firebird Phast 6. It has Mods done to make it quicker light to light. It is a 3.1L so it only goes so fast. This one gets to that speed so much faster. Some of the mods included Spohn SFC and rear control arms.
Car originally obtained for the misses. Due to old injuries she can not get up and down into car daily so now I have it. It was a barn find. I replaced shocks/struts with factory. She wouldn't need anything else. Now that it is mine and the mods are done the ride is rough (stiff, does not take bumps well.) What shocks/struts can I use to smooth out the ride. It does not have a V8 and never will. Just want a smoother ride. Help?...................

Which shocks exactly are in the car?

I replaced shocks/struts with factory (AC Delco) Using part number called out in parts manual.

You should have a smooth ride with factory stuff? If anything the factory stuff is soft. Check your front a-arm bushings, they could be worn. I would check all your original bushings for that matter. Check your tires also, if they are old and hard this will have a big affect on your ride.

I used KYB Gas-A-Just shocks in the rear. These are the non adjustable. I used KYB AGX Adjustable Struts in the front. I run setting #2 on the struts. My car has a very smooth ride with this set up.

Smooth yet crisp and precise equals Koni Yellows.

I replaced F & R sway bushings and links. installed Spohn rear control arms. So F "A" arm bushings are the only original rubber left on the car. The car takes bumps hard. I was thinking the factory stuff was too soft. MAybe I'm wrong, maybe the springs. I figured I throw it out there to get y'alls input. Thanx.

I appreciate the input on the Koni's. Can you also make a suggestion for someone who is a little budget minded?

I did...KYB AGX. IMHO these are as good as the Koni's for 1/2 the cost. I am very happy with the performance and ride quality of these struts.

I have the KYB Excel-G on old factory springs. Ride is too boaty IMHO but cornering is nice. I bought new springs (stock) but haven't put them in yet. If it is still too boaty after new springs and control arms (soon), I'll go with tighter shocks. Replaced the Excel-G's with Gas-a-Justs. Much better.
