This is the first car that I have owned that I decided to make upgrades to the suspension. I could use some solid advice on how to move forward correctly. I appreciate any and all help. :thumbsup:

I purchased some BNIB parts from a nice guy here on the forum. My goals are to lower the car on the stock PP wheels that I currently have a 1" spacer on front and rear. I want to correct some of the feeling of the car where its floating on top of the suspension, as well as the "bounce." More importantly, I need the car to tolerate highway driving and less than perfect roads in NY being my DD. Here is the list of parts I have:

Eibach Sportline Springs
Steeda Adjustable Differential Bushing Insert System
Steeda Differential Bushing Bolt Upgrade Kit - 12.9 Hardware
Steeda Extreme G-Trac K-Member Brace
Steeda Rear IRS Subframe Support Braces
Steeda Bump-steer kit
Steeda IRS Subframe Bushing Support System

My questions:
I know lowering the car will undoubtedly make the car drive a bit stiffer and take bumps harder, but with the parts listed here, will it make the car much worse to drive as my daily commuter in terms of ride stiffness? this may seem vague to ask but Its a concern of mine. Are the Sportline Springs not what I'm looking for and do I need to get new shocks and Struts as Steeda suggests?

is there anything else that would make sense to install/change out/upgrade while I have everything being installed? My buddy who is doing the install with my help recommended Rubber Dust Boots for Heim joints because of debris can will build up in the bump-steer kit. I like to do things once and do them right so what else would you all suggest I do? this is a street car only.

- Steeda IRS Subframe Alignment Kit since I will need an alignment anyway?

-Steeda Adjustable Bumpstop Kit? Replacement bumpstops to work with the Sportline shocks.

-Camber bolts?

The ride with sportlines on stock PP dampers is pretty bad. You definitely want added damping. The drop is also pretty extreme for anything but a hard parking car. You will probably need parts to correct camber from and rear.

seems to be true from what I am reading myself. Still looking for opinions on all parts. I may swap the Sportlines out for a different spring. Whats a popular spring that has a nice drop?

I wouldn’t run the sportlines. I would suggest the BMR SP080 springs. They offer a nice conservative drop but don’t beat you to death. With the BMR springs you won’t need the bumpsteer kit. I’d install everything else.

For stock PP dampers, hard to beat BMR SP080 or SP763 (less front drop compared to the SP080 @ 0.9" instead of 1.2"). Steeda Sport or ultralite linear with a 1/8" rear spring spacer is nice too, though they do better with a upgraded damper with the increase in rate over stock springs.

The Steeda Progressive Springs are a great choice for the rough roads of the North East for daily driving.

Give the Ford Street lowering springs a shot. M-5300-X

These springs are paired with the PP shocks / struts in the Ford Street handling pack.

The Ford Street handling pack is essentially the PP with the lowering springs. Just installed it on my car with a bunch of other steeda goodies and the ride and handling is amazing.


It's composed and predictable on even the bumpiest road surface without being rough. It just soaks up the bumps. Throw it into a corner or an onramp at speed and it feels like it's on rails.

Alignment will be kept within spec with these springs also.

Gonna quote Steeda Tech from another thread where I asked about dust boots on the Bumpsteer kit...

"The Steeda Rod end balls are made from stainless steel with a teflon liner and wiper. No need for a dust boot. We have sold over 20,000 kits in the past decade with no failures due to the elements. Furthermore, they have a lifetime guarantee." - Steeda Tech

I have the Steeda Ultralite Extremes and I’m on PP struts and i think the ride is good. Granted i will eventually upgrade but my camber was able to be down in the rear no problems and front too even without the camber bolts.

Running Steeda Ultralight Linears, Steeda non adjustable shocks and struts, Steeda Adjustable bumpstop kit and the BMR Cradle Lockout and and upgraded to 20inch wheels with tires. Ride is very nice and composed. Ride is stiff but not even close to harsh here in WV and coming from a lowered subie on coilovers I know harsh lol. I'm beyond happy so far with my setup and havnt rubbed once anywhere and have almost no fender gap.

Keep it all Steeda bud; swap the Sportlines for Steeda Progressives or Ultralite Linears and a set of ProAction dampers. Get a good alignment and be done.

Here’s a shot of my car with Steeda Ultralites, a 1/4” spacer in the rear, and ProAction shocks/struts:

This. Just switched to Steeda Progressives. I love my car again.

Thanks for the good post, I am researching these options.

the ultralite linear with 1/8" spacer...what is the reasoning for the spacer? is it just for looks?

I am going back and forth with the progressives vs the linear. Any opinions?
