Do you even lift, bro?

I want to lower mine as well. Too much wheel gap IMO. You'd have THOUGHT it would be a LITTLE lower than a stock SS

I don't know about Mustangs so I am not going to comment on them but I will say something about aftermarket lowering springs. It is MY OPINION that most lower the car's handling capacity. Lowering springs have too little travel, too low of spring rate, and factory dampers cannot control them well. It is basically a cosmestics modification at the expense of handling. I am not saying you cannot lower your car with higher rate springs. All I am saying is that you gotta match those springs to proper dampers. Pedders supercar coilovers have 8kg/mm springs up front. This is twice the factory spring rate but it rides and handles very well. Compare that H&R super sport lowering springs that has very close to factory rates and you'll quickly see the importance of matching springs to dampers. |

Prices are cheaper than I thought they would be. Thanks for posting this info.

They're pretty good prices, better than what I would have thought. Though the rear shock mount pricing is odd. They are the correct numbers but one is twice the price of the other. It makes me wonder if its differnt, or and error in pricing.

So it appears that the 1LE is following the "big bar/soft spring" approach relative to the SS by increasing only the bar stiffnesses. Even BB/SS tweaking affects the strut/shock valving, which we don't know anything about anyway.
Sleepy - most of the Mustang lowering springs range between about 25% and 75% stiffer than OE, and that's probably true generally. For the amounts typically lowered, that's not enough stiffer to hold the frequency of bump stop contact down to OE levels. But it is too much stiffer than OE for the OE dampers to properly control for best grip. What stiffer springs with OE damping does do is move the level of "critical damping" down toward "best ride", which may explain why there aren't very many complaints about lowering not fixed by trimming the bump stops. Geometrically, lowering springs give something up that effectively "steals" part of the benefit that the increased rate is supposed to be providing, assuming that what you're primarily after with your new springs in the first place is more spring rate. Wanna bet that most purchasers of "lowering springs" don't think past the amount lowered? Norm |

Performance springs - I like that better, but it's probably a case of shovelling sand against the tide at this point.

As an example, it is entirely possible with some suspension arrangements for the anti-squat % to drop slightly over the first inch of rear suspension compression (squat), before turning around and increasing with still further squat. Even stranger curve shapes are possible, but at least the odd variations in the middle are relatively minor. Norm |

One rather important consideration I left out ↑↑↑ is camber gain. With a strut suspension, the lower you go without getting into correcting the geometry, the slower your camber goes negative to compensate for roll as the suspension is compressed still further (consider what the outside suspensions are doing while cornering). With struts up front and either a multi-link IRS or just about any stick axle suspension arrangement, this becomes an understeer effect.

gM is a big fan of soft springs and big bars they always have been.
Someone at GM is apparently unaware that the bigger the bar, the less "independent" the suspension becomes and ride quality can go to crap just like it does with stiff springs. |
