Guys,
I have a 330# composite rear spring. Currently I am running Bilstein HD shocks. I still have a little bounce on some road conditions. Has anyone used QA1's with this set up with good results? If so which ones work the best. TS 403, TR 403 or the TD 403 are the choices I come up with.
I have heard good things about them and wanted to check here before investing. As they are a bit pricey.

I have a similar issue on my 67 Coupe but I have the replacement gray shocks. I asked about using Bilsteins HD's or sports and I've decided to go with the sports. Since you are using the HD's and still getting a little bounce I hope I made the right decision. I only ordered the rears so far. If I like them I will order fronts at a later date. QA1's are so expensive!

I just checked with Summit's tech department. They recommended the TS 403's @ $155.00 each. They have 18 settings. Can't remember what the Bilsteins were. I don't think they are that much less.

I bought Bilsteins for $90 each.

Per Vansteel's advice - I'm running the QA1 TN403 (non adjustable) shocks in the rear with a Composite Spring and I'm completely happy. I'm also running a 255/45R17 tire in the rear - not sure how much that is a factor.

Just installed my Biltein sports yesturday but had to go to my grand daughters baptism so I haven't taken it for a ride yet. I'll report back this week after I drive it.

That is good information, thanks. Do those tires fit without any mods?

No adjustments to the body, but I'm running Offset Trailing Arms which probably gives me another 1 inch of clearance. The true limiting factor of tire width came down to the distance between the Frame and Wheel Opening. We measured several times before ordering Wheels and Tires. I'm running a 17x8 rear Wheel with 5.5 inches backspacing.

Maybe I should know this, but what do you mean by "replacement gray shocks?" Delco?

Thanks

Yes.
