I just purchased a wayne dues front subframe with the C4 set-up. I need to purchase some coilovers for it. What kinds are available to me? I'd like a good shock that can be run on the street, but more for the track.
any suggestions? :lateral:

To add to this question. How do you determine the required length and valving for a given car?

I have a CD from Popular Hod Rodding's coverage of the Mule build. In it, it states they used 14 inch extended length shocks with 10 inch Springs. Shocks were QA 1 brand.

you first need to get the ride hight set where you want, check to make sure you use the right wheels snd tires, check for clearance issuses, once the suspension is where it needs to be measure the coil over mount distance, this distance will be your shocks mid compression distance, you will have to check shock manufacturer's dimentions for that (ext. length - comp. length / 2 = mid length)

Nice thank you!

I'll add that as valving goes you the driver will probably be the best gauge as to what that should be, so get adjustable shocks, and as far as spring rate you will need to know your front end weight so that you can calculate the spring load at ride hight, the good thing with coil overs is that you have some ride hight adjustment but don't get too far off that shock mid point, the stiffer the spring the less compression travel you can get away with, to a point!

hey ventura thanks a lot. I'll be looking into that when I bolt up the sub.
I'll let everyone know how it turns out when I get it all set up.

Well you can copy what others have done without all the info about a CUSTOM application or you can go through and do it the right way for your car

Exaclty. and "Custom' typically mean no options at a premium price. Another question. Do they make progressive rate coil over springs?

I don't get it, what more info should I need? It's the same sub with the same suspension I'm going to be running. Now I'll just have to tweak the details to fit my car right.

weight, wheel offset, ride height, CG and RC, I guess it's fine to use what someone else did as a base line but coil overs can get expensive if you don't get the right ones especialy for a road and track application that should use da shocks.

da being dual action???

What are some really good brand shocks like the kind you would find on a real race car but can still take the daily driving abuse?

DA means double adjustable.

real race cars are not driven on the street, but to answer the question there are a lot of "race" shocks, Penske, Afco, Pro, Koni, Ohlins, Bilstein....

seeing as how I will be driving it on the street as well as on a track I shouldn't go for these brands though right?

What other type of shocks are DA and good for both applications?

Ohh and thanks Don

shock brands make no difference as long as they are quality built, the correct valving for the application is what is important
