I looked at this last year. Its much too heavy for any serious performance applications. Its designed for comfort not performance.

A solid axle is not necessarily a deal breaker. An 07 Mustang GT is a very good performer at the track and can be easily improved to be quite decent.

I drove my friend's 07 Mustang GT, I gotta say it feels bigger and heavier than my truck, but the damm thing drives nice ! and with nothing but a high flow intake, and a tune it really has some mustard.

07 Mustang GT: 300hp/320ftlbs, 3.55 rear axle, rack and pinion steering. decent weight distrubution, 3450lbs, aluminium block...

Was that GT towing a house trailer?

Have you driven one yet Den? I feel like a midget in that cabin, I can't see where the hood ends, looking in a mirror is useless, and ford still can't manage to get all the body panels to line up...LOL, the L feels much smaller to me than the new mustang, if you can get what I'm tryin to say.

But it does handle very well, is fast, and looks awesome, I just would'nt wanna drive one on a daily basis.

I was off on my weight bias.

If it were me I would reinforce the frame where ever possible to stiffen it up, take some of the money you were going to spend on suspension and put it under the hood. You might loose a bit in the corners but you will make it up on the straights. In the "streetfighter" world it really isn't going to be about who can take the turn the fastest, but who can get to it first.
I love my truck, I just want it to handle "better"! Perhaps "streetfighter" is the wrong word choice, but I don't forsee any trips to the track. Hence the street. I want to get to the corner faster, but I want to make my trip back and forth from work fun and comfortable also.

A parallel 4-link with the links outside the frame is relatively straightforward, and provides for great dragstrip hook, but can't provide good roll steer or braking characteristics, so it's not the ideal road racing setup.

You might consider an offset 3-link. If you weld in a crossmember, you can have the upper link offset to the passenger side. All of the advantages of a 4-link without the bind.
So if I want to achieve better handling, the parallel 4 link is not better than leafs? Or if so not much. I think I can understand where it would bind.

Without opening a can of worms or a 20 page discussion, do you have an example of an offset 3-link? Is that what you posted on the first page? If I can see it I might beable to understand it better and decide if this is something I want to attack.

I've been on track with M3s, and they are about as close to a perfect dual-use street/track day car as can be imagined. Absolute rockets bone stock -- and I'm told, very easy to drive.

I couldn't even give you one pages, homes.



A 3-link is just a four link with one missing. The key thing to remember is that the third link (almost always an upper) can be offset. You could run two links below the axle, and one above offset to the passenger side.
