    I've done quite a bit of IRS upgrades, see signature, will these really add anything to be of value performance wise to make them worth the cost?

    I feel the value is there; in fact the Steeda braces are the only IRS bits I’ve added. They do as advertised.

    However, if you already have a slew of IRS mods, then maybe the braces are a redundancy. What all do you have installed?

    Here’s a brief review I did on these braces:

    Only new recommendation, now years later, is spray the braces with a rust stabilizer each year before winter.

    I have the IRS support brace. I noticed the difference right away. The back of the car seems much tighter. I also have the vertical links. I din't notice a difference there; however, I am going to get the remainder of the
    stop the Hop kit, so I will see.

    They are our most popular IRS mod - they have been proven at the strip & at the track - they are a good investment :)

    Just installed the IRS bushing support system. Definitely a great mod for the money. The car has significantly less wheel spin/hop and I hear little extra road noise. If your looking for a suspension mod at the right price this is the one. Very Happy with the install and highly recommended for the price.

    I have the IRS braces. Calling them IRS braces doesn't do them justice. Chassis support braces is a better term. I needed to jack my car up today and the chassis is so stiff I lifted 3 wheels off the ground. I was jacking from right in front of the rear wheel. The jack started acting funny and I looked, both rear wheels off the ground and the same side front tire was off the ground.

    If you like a stiff chassis, these are the ticket.

    Just to clarify, this happened before I got the car high enough to place a jack stand.

    They are absolutely worth the minimal cost. Combined with your current mods they will stiffen up the back end and make turning at speed a breeze.
