I need some advice on road course suspension upgrades. I plan on doing a few events a year and enjoy performance upgrades. I've got rear lower control arms, strut tower brace, and Hawk HPS pads. I would like some advice as far as springs, shocks, and struts. I've been thinking about Tokico D-Specs and Steeda Sport Springs, But recently started considering coilovers. Keep in mind, this is still my daily driver and just want the best bang for the buck. What are your thoughts?????
 
I've heard the Roush suspension setup actually is still daily-driver worthy, while offering great performance. It is the only setup where 05+ mustang has pulled over 1g on the skidpad, according to Roush. At about $1450 for the parts, it may be more than you wanted to do in terms of price.
 
Steeda's suspension is also 1G+ capable and drivable on the street.

now if you really got money to blow and want the ultimate mustang suspension the GR40 setup will pull 1.55G but be prepared to drop some serious cash for it tho. :)
 
Holy crap! Is that on racing slicks? Its gotta be... I don't know of any street tire that can produce nearly enough to allow a car to handle at 1.55G. I couldn't imagine that... that's F1 territory! Depending on how high/low speed of a corner it is anyway....

Nah F1 is more around 4g's of side load, but a well tuned FIA GT racing car will go past 2 easily so that isn't totally out of the question (as the vids in the site show). But yea you're right you gott have some serious wheel/tires to handle that type of suspension setup. Definitely dont want to be driving all out on the stock KDWS :eek:

(that's love right there)
 
F1 cars tend to not handle comparatively well at low speeds. They rely more on aerodynamics to produce insane downforce at higher speeds which results in the 4g's. At low speeds, aerodynamics haven't quite kicked in yet, so their "mechanical" grip is lower - around 1.4-2g's depending on the year in question. F1 cars are one of the few that will significantly improve handling as speed increases.

Either way though, thats still insane for a Mustang. $8700 though is quite the chunk of change.
 
It's hard to beat the Steeda stuff in "bang for the buck". Steeda springs, d-specs, and anti-roll bars would be a great way to go and you'll really appreciate the adjustability once the under-steer starts to drive you nuts. That's basically my set up (although I went with eibach springs- wish I hadn't though) and I have no regrets.
