    Default Upgraded quad shocks suggestions/worth it?

    Right now, I don't have quad shocks on the car. (88 mustang gt) Now I'm pretty sure it's not performing as well as it could because of that, but I'm wondering, there are options out there ranging from $20 a shock to $150 a shock. How much is too much? Anyone have experience with the Koni Reds, Bilstein, or KYB Gas-a-just? The $20 ones from Summit are just stock quality, I believe. Also, will I have issues with 9" wide rims in the back. I guess I can put my tired old ones on to check that. I just took them off before I put on the wheels reading they can be an issue, didn't even check it.

    I can't see that how $150 shocks in the back is really going to make a change unless I'm drag launching the car, but I do autocross, so I am pushing the rear end a bit. It can definitely get loose sometimes. I'm still finding that limit (a little too often).

    Thanks for any feedback. I'd really like to hear from people that have used them/used different ones.

    I have the KYB rear quad shocks on my '89 and it's a noticeable difference when the outer "anti-hop" ones were removed vs having them all installed. My car is set up with daily street and occasional auto-X driving in mind.

    I'd recommend always having quad shocks on the car unless your rear wheels are too wide for them to fit (turning the outer shocks around to mount the opposite way might help solve that issue) or you have something else major (traction bars or something) already fitted that renders them unnecessary.

    I would get rid of the quad shocks. If you have plans to run a 275 or wider rear tire, they won't clear.

    I would look into upgrading the upper and lower controls arms first. Stiffer control arms, adjusted to the proper pinion angle, will take care of all wheel hop problems. A decent set of LCAs can be bought for ~$200. That would be money better spent than ~$150 for quad shocks.

    I have some better not so better control arms, SR performance, the American Muscle brand. I have a set of used steeda lowers as well that aren't on the car. Ill only be running 255 probably. So I guess rather than spending that kind of money on quads, which I'm still curious who spends that and why, I should get an MM panhard bar.

    I drive a Prius.... and an 88 Mustang GT. Guess which one is more fun.

    I agree with MGLT, spend the money on better upper and lower control arms and ditch the quad shock

    Still run the stock quads on my '03 with MM lowers, Lakewood uppers, and a 315 tire

    quads can go after upgrading UCAs/LCAs to a different bushing material
