Suspension Questions 2010-2014

It's been said a thousand times "I was spinning" when it comes to a Mustang's traction.

What are the culprits of this? Is it a couple parts or the entire design of the suspension?

It SEEMS to me that Corvettes generally hook better judging from online videos? If that's so what is it about their suspension that's so vastly different than a Mustang's?

I know we aren't corvettes, I'm just wanting to build my knowledge on this because we all know power is useless if it can't be planted well.

Thanks for any info/links!

Mustangs have wheelhop and spin issues due to soft rubber bushes in the rear arms. Replace the upper for wheel hop control and the lowers for ****s and giggles. As long as you aren't lowered you'll get some help here. If lowered you may need to put relocation brackets on to get your lower control arms aiming downward from the front mount to the axle.

The biggest single contributor to spin is inadequate tire size on this car. Even the Track Pack/Brembo cars only wear 255. 275 is what I'd say the car needs, minimum.

Yep, after rear UCA the next larges contributor is track width... You can get an awful lot of that with tires. As stated if you've lowered your car, relocation brackets will be needed. They help add anti-squat which is what you are after initially. Chances are you will quickly firm up the suspension to the point where tires will be necessary to reap all the benefits.

To directly answer one of your questions. The mustang is not really all that different from other OEM applications. All OE stuff is for comfort and safety, you compromise performance to achieve that. Most if not all changes to your car to help it "hook up" better are no different than any other rwd car. The actual differences are which parts you change.

What have you done so far with your car? Do you plan on making changes? was this purely to learn, or are you considering something in the near future?

Thanks for all the info guys.

I'm lowered on BMR springs. I intend on buying their boxed lower with brackets and adjustable upper. I'm thinking I'll be ok with the stock upper mount?? I also intend to fit a 305 back their soon.

I would not recommend under any circumstances boxed arms.

Nope.


And the height of the sidewall is more important than the width of the tire.

Only in extreme cases, otherwise a wider tire gives a larger footprint, a taller sidewall does not.

No way dude. You think a wide footprint with say a 30 or 35 series tire is going to hook with any decent power?

Vs what?

I said extremes for a reason....

Keep in mind the tire footprint goes both ways....side to side and front to back. Depending on what you choose, you can enlarge the footprint both ways.

No radial sidewall is worth a damn for transmitting power on road surfaces, even a drag radial. The radial carcass is just inherently stiff so, concentrate on tire compound and as big a tire as the rim will hold.

Absolutely tire compound is important. As for the footprint I was generalizing. It is not entirely accurate to assume track width increases with tire width. However same for the sidewall height, all it does is generally modify the footprint to be longer and not wider but the overall area is more or less the same. Which leads into discussions about vertical load, tire pressure, etc.

However as it relates to the OP a wider tire will help after control arms and before anything else, we both agree there.

Okay, and why is that? It's best I go with a mount from the same manufacturer?

If you are not going to get a watts link, then I'd recommend spherical bushings. Boxed arms have little to no flex at all and will bind and over time the axle articulation will damage the boxed joint since it is solid and has practically no give.

Like a good old fashioned torsion bar, round tube resists twisting forces very common in the suspension action better than a box. a box, when twisted, will fail in mid flat bc of the work-hardening at the corners, if the stress is high enough. Round tube spreads the load all around the bar.

Now, directly answer what the best setup is for 1.70 or better 60's.

A slick tire and upper and lower arms. On stock bbp springs, bars and shocks, that was good for 1.5 to 1.6.

I'm at around almost 600whp. I threw on 275/60/15 MT drag radials. I'm hooking way more.
