SGT T Chiming in here a little late. I run the STR.Ts with K-Springs, and have no complaints about the ride. A little expectation management goes a long way. I think if youre prepared for some ride stiffness then you wont be disappointed. If you want a really comfortable ride then lowering the car will always bring some frustrations from time to time.

I used the gt500 mounts. I dont have any noises or suspension issues. I think it rides great and handles great.

I still have some body roll, but I attribute it to needing some better sway bars, a STB, and some better control arms/control arm brace.

Anyways, I have a set of used Bilsteins sitting in the garage. I kinda promised to sell them to this guy at the track but I won't see him until first weekend in December. But I might be persuaded to sell them if you are interested.
I didn't update this week but I replaced the struts with a friends used set he found he still had after he lowered his car, and replaced the bad tire at the same time. Problem is gone now. I assume you were right with the struts since rotating the tires didn't help before changing those.

I will pass on the Bilstein's since my Christmas gift from the girlfriend is the Koni struts and shocks. I really appreciate it though. Since the car is off of daily duty I am gonna make it a nice little cruiser and finally be able to enjoy it on weekends after daily driving a Honda Fit.

Anyone have experience with the ST stuff? I don't mind waiting until the Koni sale goes on again, if ST is not worth it, since it is off DD duty now and will see maybe 20 miles a week until Spring.

ghunt If the ride is that good I might pick up some BMR springs myself. I have the P springs and I agree, the ride is pretty crappy.
November 6th, 2015 05:52 PM
AR Stang That sells me on the BMR one's for sure. This state has enough bad roads even when they are paved. The last thing I want is to be annoyed driving the car.

I can vouch for for the way the progressive rate springs ride over bumpy terrain, not good.

I feel ya on the mileage. I've managed not to mod this thing since I bought it new and be a responsible adult. Now that it is off of DD duty, and my house down payment is already set aside, I am gonna splurge on it a little bit and install over the Winter or Spring once I get it all bought.

The GT500 mounts will also work with the P springs, you shouldn't need any camber adjustment with such a mild drop. If it's not in spec, just rotate the mounts 180* and that should bring it in.
If the Ford Racing Springs are more harsh then I will be going with y'alls that are listed above. The half inch lower drop I will live with if they are a nicer riding spring. I take a few non paved roads when I drive the car and don't want to add a lot of harshness with the Ford Racing springs.

I don't have experience with the MM plates but even without adjustment I still had about -1 to -1.2 degrees of camber in the front which is about where I wanted it.

I guess since no one is chiming in with ST reviews I will stick with the Koni orange's.
My J&M plates failed within the first year, made a horrible noise over bumps and I couldn't keep them tight to the strut.

After about three years of dealing with that and the popping and wore out J&M camber plates I went with the following parts and part numbers from BMR. The ride was phenomenal. I went again with Koni STR.T and loved the ride, the difference from the BMR handling springs and the FRPP K springs was night and day. The BMR springs had a much better ride and were more predictable when getting aggressive.

Koni Orange's or ST Suspension Shock/Struts

So after going through all the stuff for my steering wheel shake at 75-80mph. 07Boss suggested I look into my struts being changed out since I have exhausted a lot of other areas. Car is an 07GT and has just under 89k miles on original shocks/struts. It see's 99% street use so I don't need to go adjustable's or anything like coilover's.

I am looking at the Koni Orange's, which I have read a lot of reviews on, and the ST Suspension shocks/struts. Car will be getting Ford Racing P-springs along with them.
