What to do next?

[ForYourOwnGood]

I have to get aligned again because of the rear end accident my car had, and I'm trying to track down what all I might need to get it squared away properly, I forgot it after the repairs were done and I was getting some wear on the tires that looked like toe out. I have also added some weight to the front with a supercharger and now it sits even lower.

What I have:
- Steeda Subframe alignment kit and differential bushing kit
- Ford Performance M-18000-F shocks
- Steeda min drop springs (advertised 0.5" but in reality 1.5"/1.0")

What I'm ready to buy:
- Steeda bumpsteer/roll center kit
- BMR rear shock mounts (Have the steedas, just don't like them too much so I put the stockers back on).

The front is VERY low compared to what it was supposed to be with these springs, so I'm a little irritated with that. Even before the blower the drop was well over 1". I am about to order the roll center and bumpsteer kit, is there anything else I should get before I get it aligned again? I don't really have an issue with the base GT sways, I don't do any performance handling oriented stuff and it feels good right now for street only use. Camber plates for the front? Adjustable toe links? I just want to get it nailed on the alignment so I don't ruin my set of new tires.

I wouldn't do any of that (besides the shock mounts) if you're not doing any performance driving. Only do camber plates if you want to focus on a perfect alignment. Perhaps try the BMR min drop performance front springs (SP089) to bring the front up. It'll end up at just about 1" drop with a blower. Or GT350R fronts...which will sit at about 0.7-0.8" drop with a blower. They would not be harsh with the dampers you have. They would also control the weight of the front of the car better and give you more confidence.

The biggest thing I want to address is the bumpsteer and tire wear. It feels fine the way it is handling-wise although I scrape a lot where I didn't want to because of the extra drop. The bumpsteer and tramlining are really, really bad. The worst of any car I've ever driven.

So you suggest just the shock mounts? I have a discount coupon for Steeda which is why I was going to buy that kit.

The Steeda bumpsteer/control arm kit will help your bumpsteer a lot and should help tramlining some too. For the tramlining, look at what tires you are running also. The wider and stickier tires will promote more tramlining. My bumpsteer and tramlining though got so much better with the Steeda lateral links and bumpsteer kit. Still have some tramlining due to the 285 tires I run, but there you go.

Good luck.

Stock PP1 wheels with 255/275 MP4S. It's better than when I had 285/305 MPSS by far but still bad.

Raise it up and it'll fix itself. I had zero before I installed the RC correction kit with GT350R springs. Honestly I'm not thrilled with the bumpsteer/tramlining I have with those parts already installed and adjusted. It's manageable but not ideal. The handling gains when driving it at the track are worth it, though.

I do like the shock mounts, yes.

What’re your thoughts on the diff bushings? Do you like them? They’re such a hot/cold thing with people. I’ve got to replace my stock ones.

I didn't notice any difference really but I don't track or launch the car anyways. I just figured there cheap to do while I had the subframe dropped for the alignment kit. THAT did wonders, removed all of the feeling of shuffle in a corner out of the rear.

Get the sleeves for the rear bushings from the Lethal Extreme hardware upgrade kit and be done.

I will have Jigar reach out to you. That drop is not normal with our minimum drop springs.

This. Raise it back up and it'll fix itself for the most part. When the car is too low, you run into this issue. With BMR SP080s I had bad bumpsteer and tramlining. In certain situations it can make you really nervous.

I've come to peace with the tramlining. It's part of the firm sports car suspension and stickier tires/alignment. Its going to tend to follow the road some. Having the car setup correctly can help. Even the GT350s will do this too.

OK I went ahead and got the BMR tubular vertical links, for $89 I couldn't see any downsides and their new upper shock mounts. Both seem to do their job very well, the vertical links really cut down on the wheel hop and the shock mounts actually helped out with the ride significantly.

I'm steering away from raising the car back up with springs, I really don't want to risk taking the rear subframe back down to get them out again and I don't know about mixing and matching. I'm considering some of the spacers Steeda suggested when we were talking about my front being lower than I want it to, I'm assuming they go between the body and the top strut mount which is another option.

I'm also looking at sway bars, I understand the dangers of having them too stiff but I have base GT sways not even the PP ones and it does feel a little mushy. Not looking to go full tryhard corner flatter than a pancake but a bit of an upgrade wouldn't hurt. Not going to do more than one thing at the same time though, I like to do suspension bits one at a time and see how it feels.

I'd personally recommend just a front bar upgrade. My experience on this car is that the added bar stiffness reduces roll, improves front grip and rear stability simultaneously. It goes a little counter to classic stiffer = more understeer, but there are valid reasons for why that works. I'm a big fan of the BMR bar, currently using on the medium setting.

If you haven't purchased/installed the bump steer and roll center kit, for sure do this first considering how much your car is lowered. I can't praise these enough for how the dynamic of my steering has improved (I'm lowered 1.1F / 0.5R).

Considering you have base sway bars, for sure look into upgrading the front and rear in the future if you want better handling. I always recommend adjustable units, though, to be transparent, I use my OEM PP front with an adjustable Steeda rear and love it.
