Lowering Suspension?

the difference is with the coilover the spring is mounted over the strut. the kit you buy will come with a threaded sleeve, spring pearch, etc that you will put on over your strut. You will probably have to modify the strut so keep that in mind. The main difference between daily driver and something more aggressive is the spring rate. Keep in mind you have to match spring rates front to rear and also match them with the struts you choose. I have the Maximum Motorsports coilover kit and I'm pleased with the quality. I have coil overs up front and rear springs with adjustable lower control arms. it's thought that rear coilovers aren't really necessary for street cars.


Edit: looks like the one you linked already come with everything assembled, that's another way to go. Not sure on the quality of that stuff though.

 

I've seen the SR coilover kit on AM's site. Personally I wouldn't touch it with a 10 foot pole until someone else spends the money and is the test dummy for all of us waiting to buy it lol. I'd wait for some reviews, just my 2 cents though.

 

1. Its a bit on the soft side for daily driving and you'll prolly be bouncing around
2. You dont have much room for adjustment only 1-3" which is nothing
3. SR makes Stuts and Shocks? lol

 

Don't buy a coilover kit that already has a spring rate picked out. Put together a kit with what you need, not what a company thinks you want.

MM, Strange, UPR are all good kits. It all depends on how much money you want to spend, but either of those kits will be fine for a street car.
Try and keep the spring rate over 250lbs for a daily.

 

Yeah put one together.

I chose H&R race springs from a 99-04 Cobra and Steeda Comp rears. I am going H&R super race in the rear and 4 point as I hope to try out autocross this summer.

 

When selecting spring rates as it was mentioned you have to match the front with your rears. Your vehicle weight will also factor in how much spring rate you'll need. A 3600lb vehicle with you in it, a 300lb front spring rate is considered soft but it will drive & feel smooth, along with improved handling. As far as picking struts and shocks, I tend to lean to companies that cater to road racing vs. drag racing. Koni, Tokico D-Spec, Bilstein

Now your ride quality will improve with a coil-over vs. the traditional strut and spring setup and the difference is noticeable. As for the rear as it was mentioned above not really needed for a street car but you'll need a lower control arm with adjustable perch to adjust ride height. I would send Maximum Motorsport tech an email and ask for their opinion because there is a lot of things (sway bar, K-member, A-arms, chassis stiffness, etc.) to consider when doing this.

 

+1. I did just that and they helped me pick out my coilovers. Great guys to work with.

 

If you have Bilsteins, go with the Maximum Motorsports kit (http://www.maximummotorsports.com/Mustang-Coil-Over-Kit-with-Springs-Front-Bilstein-Struts-P506.aspx)
It's the best bang for your buck since you don't have to get new struts. Try buying a used kit on the corral if you wanna save some money.

If you want to drop it around 3" you'll be fine with a 12" spring. Any lower and you might want to go with a 10" like myself.
And based on your original post, for daily driving + the occasional fun, I'd aim towards a 300-350# spring rate for the fronts and about 100 less for the rears (which is what is advertised by mm)

PS; Thanks! But I'm always 1 step behind in the stance game lol.

 

I'm dropped about 3" in the front with 250lbx12" springs

 

BC Racing coils cranked all the way down till the frame rails rub.

 

You need to see what us Vert Guys are running. It's got different weight then a Coupe up front.

I dont see see how his is 3" when mine rides almost identical appearance. I can only fit 1 finger between my tire and fender. The spring I used was rumored 1.6-1.75 and then I don't have upper or lower ISO's so I highly doubt mine is 3" .
