      Any performance AWD cars with double a-arm front susp?

      I've got this crazy idea in my head to make my build AWD. I'm trying to think of performance AWD cars with double a-arm front suspension. Strut would work, but the handling wouldn't be as good (I don't think.)



      I thought about using C5 front susp and machining a wheel bearing to work, like the rear C5 bearing.

      Basically, I'm building the front from scratch, so I'm open to any and all ideas.

      I don't have a problem using a strut setup, just not sure if I can make it corner moderately well.

      C5/C6 components would be the best to use. The stock geometry is actually very, very good and can be modified to suit your needs. Like you said, just use the rear bearing pack for all corners (I think they're cheaper, too). Struts work OK sometimes, but A-arms work much better.

      Handling wise, I think you'll have some difficulty getting it to corner hard without pushing too much. It's a delicate balance with AWD cars and proper power distribution. I think they're easier to drive hard if you're a novice driver, but letting the front wheels just do the steering work usually proves to be better.

      I can see that severe pushing could be a problem if the front tires are spinning...LOL

      You would also need a Tru-Trac in the front diff or something to help you turn.

      It does seem like traction control would be the major issue. Well, and space to fit the diff. if its not a small diff like on the audi. Then how much torque can those lil diffs handle.

      I have a 2008 sequoia that has a front diff. and A-arms, kinda big for a car. Had a 4-runner too that had a front diff, alot smaller but still handled the power. And it wasnt limited to speed, well not too much. I would regularly cruise at 80mph in 4-wheel drive.

      Personally, I would look at a designed (production) front end that drove the front and rear wheels. Not a front wheel drive car cause they have the tranny too involved. But a 4-wheel drive car (subaru maybe?) or a small truck. One that has a rear tranny (behind the engine) and carried the power to the front with a drive shaft. Packaging is gonna be a bear. But maybe not with a 4-runner type drive train. Id really look at a 4-runner drive train. You can get them for a decent price. Dont go too old though. Say no older than 1999.

      This is gonna be a nice project to watch play out. Im really interested to see what you come up with. JR

      I don't claim to be an Audi-guy, but the S4's make ~350HP dead stock and I've seen some insane after market power numbers. You never really hear of diffs breaking.

      I love the awd idea keep us posted on you choice. a subaru wrx might be an option or a mits. evo. both can handle tons of hp. good luck with whatever you choose to do.

      Steilow commented on the quadradeuce set up along time ago on this site. Many one off parts and couldnt realy handle much power. Saving grace for the Deuce is low low weight.

      That was all based on the Dodge Stealth / Mistu GT3000 AWD stuff if I recall.

      I'll probably end up using the Syclone stuff if I decide to try it. There are guys running into the 9 and 10's on the stock t-case and front diff. So, we'll see.


      That project AWD Camaro looks like a good resource. Didn't know the STS was AWD. Looks like he has the same idea as me with the C5 stuff.
