I keep all the drawings I can. If you have an order number, I could look it up. I have all the details on these rails anyway.

A note on Camaro rear rails: The profile of these are very difficult. I am not aware of any mandrel bender in the country than can bend one in one piece, seeing as there is a compound bend at the rear (a hard and easy way bend in one location). But there is a way around it, and that's what we call a "cut and weld". This is where we bend two pieces of tubing, trim, and weld them together. This is an expensive process. But really, you only need to do this if you want to keep the stock gas tank. If you're willing to go a different route (I always say "never let the rear seat or gas tank design your vehicle") and do a narrowed tank/fuel cell, you can run the rails completely straight. You'll gain lots of tire clearance, and just make the process easier and cleaner.

Matt, you are right. Now that you mention it, my rails are straight. I have a fuel cell in the trunk so the additional bend was not a concern.

I wouldnt mind running straight rails but I called up DSE and I was told the panhard bar was engineered to fit factory width frame rails and if I used straight rails measurements and fab wuld be more complicated. I rather pay a couple more buck and keep the guesswork out of lining up a suspension.

Mark, if you could quote me on how much it would cost to profile rails exactly to GM specs and have them extend to meet the front subframe I would appreciate it.

when i talked to DSE a couple months ago, they told me i would have to shorten the panhard bar. They told me i would have to take off the amount that i moved that frame rail inward.

[gearhead1186]

now would you remove a piece from the center or cut off the brackets and take off a piece from the end? depending on how much it costs to fab up exact rails this might be worth it

[freebird]

my understanding was to cut the side that is adjustable. It has thread bung in it, cut that off and shorten the rod and reweld bung.

Much easier to get the bar itself modified. The brackets are designed to work and add strength so I wouldn't mess with them. But you may have to tweek it abit to fit a straight frame.

thanks guys.. ive been hunting around forums for rear suspension options. since i might do straight rails, DSE isnt my only option. How does the quadra link comare to a 3 link or a tri 4 link? Im lookin mostly for handling but I want it be able to run low 10's.

i have talked to the AME guys and have done some rsearch and i have decided to go with the tri 4 bar. The problem with me on the 3 link is you cant have a back seat unless you go with 3rd / 4th gen seats.
