So basically I bought the car and it was already lowered (eibach sportlines).....but the stock shocks are still on there....I have two general questions...I just got my Tokico D-Specs in today and was planning on putting them on in the next couple of days.....i would be attempting it now but i just had Lasik surgery on my eyes today so i'll be out of commission for a day or two...anyhow it mentions using a bumpsteer change....is this absolutely necessary?......the other question is with sportlines ( i understand its lower than the prokit and a stiffer ride), but can i use the softer settings to make the ride a little smoother...or would it cause me to rub when i hit a bump/pothole?

 

The need for a bumpsteer kit is entirely dependent on the amount of lowering you've done.

My coilover setup lowered the Mustang three inches, so a bump steer kit was mandatory.

Below are two links to help you gain a general understanding of bump steer, and maybe help you decide if it's in your best interest.

Generally speaking, the tie-rod should be parallel to the lower control arm. If you peak underneath the vehicle, you'll be able to make a quick assessment. If it's not parallel, you'll have the drivability and possible tire wear problems mentioned in the links below. A bump steer kit allows you to make the adjustments needed to get it parallel.

Ditch the springs for pro kit or similar drop. Sportlines are WAY too low. They actually HURT the performance of the car. Spend $200 on a set of springs and save yourself the headace. The Sportlines are gonna ride like **** anyway no matter what you do. It's just too damned low.

 

well crap....how difficult would it be to install the pro-kit then?

 

Not very hard; you have to take the springs off when you go to replace the shocks. It's just a matter of swapping them out in the middle of the process (at least, following along with TacoBill's install guide).

 

I am in the same boat, i got my D-Secs in today but i won't be installing untill i get the rest of my parts.
But I have the BMR spring kit, 1.25" drop in the front and 1.75" in the rear.
Do you guys think the Steeda bumpsteer kit will be required?

 

i think its looks good. it all depends how much you drive the car. i have the sportlines with d-specs and love it, but i will also sacrafice ride for looks and handling. if you have a daily driver, then the pro-kit is the way to go. i didnt even need an adj. panhard bar and its still good. jmo.........
