Did DC or Mopar do a race bulletin for building a Trans Am race car? If not is there a definitive place to get some information on suspension? I am building a 73 AAR Type Cuda. Basically I want to build it as a streetable road racer.

Thanks for the links and information. To b honest my "plan" as it relates to what I am going to use the car varies day to day but I would say it will predominately a street driven car.

However, in saying that I want it to handle like a race car as much as feasible. I (like everyone) looked at the tubular K frames and suspension thinking they were more "modern" however after quite a lot of research I have decided to stay with the original configuration except with some upgrades such as tubular upper control arms, reinforced lowers, adjustable struts, big T bars, FF stage 3 box, fast ratio arms, poly bushings, etc. Basically I want this car to handle as good or better than my ACR Viper.

I completely understand the issues and perhaps my answer was a bit too generic. When developing this concept I used the Viper as a "mark on the wall" so to speak but I know that the Cuda will not be the same. I guess a better statement would be that I want the Cuda to handle as well as I can make it within reason. The "reason" would be primarily financial. I really like the XV stuff but dont have the $$ to donate to it. Maybe another way to look at it is that I want it to handle better than the original Trans Am cars but still be streetable. My Challenger has all new poly bushings and slightly larger T bars and while it drives "ok" it is drives like a 70 Challenger (it is my 9th). My real objective with the Cuda was to modernize the car again within reason. I intend to run a 4 link rear, EFI system but retain the 340 and a 4 spd. I thought about a 5.7 and a 5 spd but it is too over done now and I like the historic value of the 340 4 spd. In the end I want it to look like an AAR but with enough subtle changes to make it interesting. I would run it on a road course but given my schedule and other issues I doubt I will any time soon.

What do you think about the 4 link? I havent installed it yet but I have all of the components. I have already installed a rear end brace.

On a related note, what is your opinion on PS verses Manual? Keeping in mind that the car will be driven primarily on the street I am thinking PS.

I used .940 T bars on the Challenger.

I have a triangulated 4 link set up from Art Morrison. I did quite a lot of research on the rear suspension and from what I gave figured out it should work well. Plus it gives me more space under the rear end. I want to run 315's on the rear and have already widened the rear tubs.

I think the 4 link will work well and I really wanted to do it (one of those things). my one issue is figuring out what shocks or better said lenght of shock to use.

I am looking for 275's up front and 315's in the rear. I opened up the rear wells enough to take the 315's but I am not sure if the 275's will work up front (read somewhere that they will).

BTW - I appreciate the time you are taking to talk to me about this. I have spent a lot of time this last year reading and researching and trying to balance what I would like to what will work. This is a long term project and I am trying to get the sheet metal done now but having some issues. I dont care about originality, I am interested in designing something that works. I am pretty creative and have some decent fabrication skills along with all of the tools (MIG, TIG, Plasma, Mil, lift, etc). The car is on a rotisserie right now.
