Im in the process of getting a quote for springs. I found a good Mustang only shop in my area. I had originally wanted Eibach but they suggest Steeda and since I see them talked about a lot here (including having a rep) I figured why not.

What should I get on my Mustang convert with the OEM 20's that will fit the best? I want performance over looks. I don't mind stiffness, the Stang is not much of a daily driver (I drive my 2004 Honda Civic). I'd like to hit some autoX and track (circuit) with it casually. Obviously I dont want the 20's to rub, I'd like to replace the rubbers with wider tires when they burn out (265 now, hopefully 285 later in the rear kinda thing)

Whats the real dif between progressive and linear?

Spring rate is the biggest difference besides a little lower ride height in the front with the progressives unless you choose the ultra lite linears which then have the same ride height as the progressives.

My recommendation would be the progressives since you have a non PP car as the rates of the progressive would be better matched to the stock struts and springs. Unless you plan on upgrading your shocks and struts in the next 3-6 months, you can then go the linear route.

Thanks for the tag, [MENTION=7398]Todd15Fastback[/MENTION] :)

[MENTION=18215]Starman[/MENTION] I'm happy to assist in outfitting your S550 with the perfect set of springs. As Todd mentioned, both the progressives and the Ultralite linear springs lower the front 1.125" and the rear 1" to level the car out.

The progressives are 10% stiffer than the PP springs at curb and can reach up to 40% when under load. The Ultralite linears are a constant 20% stiffer than the PP springs - the main difference between linear and progressive is that linear spring rates do not change while progressive spring rates change based on driving conditions. The reason racers choose linear springs is for consistency, which is key when tracking the car - they need a spring rate that will not change.

There's a reason our progressive springs are the premiere spring of choice for the S550 - they are ideal for daily driving comfort while also providing a noticeable handling increase over the PP springs. If you're going to be tracking the car once or twice a year and will be mainly driving it around town on Sundays, you can get away with the progressives. If you're going to be tracking the car often, I'd recommend the Ultralite linears for sheer spring rate consistency.

Hope this helps, feel free to send me a pm though!

Thanks,
David

You mentioned how if he doesn't have the PP, he should get the Progressives. I know that the PP offers the "heavy-duty front springs", but is that why you think he should go with the more conservative spring rate?

I plan on lowering my car when I get my rims (could be in 2 weeks, could be in 2 months), but I want to know if I will be running in to problems 4 years down the road if I lower my car with the Progressives or Linears (any springs for the sake of the question) with the Premium non-PP front springs (or backs). I've had the Eibach Pro-kit on my 2005 mustang with stock springs and had no issues for 7-8 years. I'm not comparing Steeda and Eibach, just wondering whether the non-PP struts/shocks can handle about an inch lower with the newer springs?

The shocks and struts that come on the GTPP and those springs are different rates for the springs and struts. They are firmer across the board vs. non GTPP cars.

I think you will be ok with running progressive springs with your stock suspension struts and shocks. David can confirm.

From my conversation with Steeda you can also use the progressives with a PP car as well.
