So, after reading a ton of posts here, I decided not to buy a suspension package. Instead, I am leaning towards D-specs, Steeda Ultra Lite springs, adjustable panhard bar and maybe a rear sway bar. The car will be mostly street driven with an occational autocross.
My question is...
How much is the alignment going to change? Will I need camber bolts and/or plates to make it be in spec? Also, does anyone have the specs for a slightly lower car? How will my alignment guy know where it should be?

Thanks for the help. This forum has been a ton of help for me over the last 3 months. I had been out of Mustangs for a little while (Audi S4 twin-turbo).

Thanks again

 

I have a similar set-up (see signature). Prior to purchasing the parts I emailed Steeda regarding alignment/camber adjustments. With the ultra-lite springs Steeda recommends 1.4 - 1.6 negative camber which is within the tolerance of the stock camber bolts. Shoot them an email they are quick to reply.

 

Thanks for the reply. How do you like your setup? Is it a noticable improvement over stock?

 

Well worth the investment and big improvement over stock with no added noise, vibration or harshness (NVH). I chose the Steeda ultra-lite springs and pro-action shocks/struts based on research on this and other forums. I wanted something that would significantly increase handling without creating a bone jarring ride or trouble w/speedbumps, curbs or dips in the road.You'll pay a little more for Steeda products but the quality/customer service is top notch and my Ford dealer is a big re-seller ofSteeda Mustangs/parts and has indicated warranty coverage won't be a problem if needed.Butit all really boils down to what you want.
