Well said and well done rcm!
I put on Eibach Pros (I think the Sports are too low and too harch.) Loved the look, and better handling. I did not need to extend the camber adjustment with bolts or plates. I will go against Mr.V and say most (2 out of 3?) do/did not need those?
A while later I added the Eibach Anti-Roll Kit and think that was an even greater handling improvement. I highly recomend stronger sway bars for all that may drive their car hard while turning, like on a on or off ramp is where I noticed it the most. The wheels stay under the car and not like stock when it felt like the wheels were on the road and the car was on the side hanging over the ditch...
I then wanted the rear end straight under the car. I have wide tires and the left rear was about an inch closer to the wheel well. I could notice, most others probably could not. I did not notice a handling improvement, was more cosmetic.
I also added LCAs and a adjustable UCA with stronger brackets and a TQ-brace under the tranny. This is more for the strip. But the TQ-brace is really nice under all hard accel!
And finally I added some Tociko D-Specs and OMG what a differance! HIGHLY recomended! What pieces of enginering!!
I would check the total price for Eibach Pro springs and anti-roll kit, an adjustable panhard bar and D-Specs. I think you'll find that for just over what the FRPP handling pack is and hopefully realize how much better of a deal it is all in all with the adjustable dampeners. Remember to add an adjustable panhard bar to the FRPP kit... also the strut tower brace is not really needed on our already quite stiff, for stock, cars.
I got my Eibach parts (about $225 springs and $275 anti-roll kit) from Sacramento-Mustang Parts - Restoration to Race, Mustang Parts
they used to be the cheapest but have lately not impressed.
Tokico D-Specs from Ebay. $515.
Adjustable panhard bar (~$120) and some other parts from CHE / Powerhouse. www.powerhouse411.com
