Attention autocrossers and track junkies, if you were going to custom design a spring (for use with an aftermarket damper) what would you want?

In other words, is there a niche out there that is simply not being filled?

What would the specs be and what dampers would you choose to pair them with?

i'd get an Eibach-developed spring in the 600lbs range, linear or lightly progressive (20% to full stiff or so), at a 2" or so drop

i'd pick konis revalved and shortened to fit

Keep the same f/r ratio and drop as the H&R race springs...but about another 30% stiffer...and revalved Konis

I like this idea except full linear with higher than H&R race spring bias to the rear.

Springs - stock diameter, 425 lb/in front, 500 lb/in rear, 1.5" lowering in front, 2" in rear but with the K&W spring perches that allow for height adjustment.

Dampers - Bilstein monotubes with 1.5" shorter bodies in the front and 1" in the rear. Preferably 41mm internals.

Sounds like a plan.
You can already get heavier springs with a couple of the available setups, but the specifics of Rich's suggestion sound great to me.
I don't care for a 1/2" difference F/R, but if they had adjustable perches, that could be dialed to taste.

Just to clarify, I'm looking for a spring that people would want that isn't readily available... I've got a contact in the performance spring market and I'm thinking of producing FJ Werks springs if I can come up with something a bit unique.

IMO, Rich's suggestion meets this criteria, but, as always, dampers are part of the deal...
If you only want a spring package, you might replicate the stats of the 1.6" Apex setup that is no longer available, PLUS a "Stage 2" set that's 2" drop and around the rates that Auto-X_ZTS mentioned above.

Springs that meet the rules [whatever they may be] for the up coming Focus Cup.... Also, if you are looking to sponsor an East Coast Focus Cup Car. I'm throwing my hat in the ring.

I think if you do the math, my "30%" suggestion is awful close to Rich's 425/500 numbers (H&R Race is 325/375 x 30% is 423/488). I am not familiar with the specifics of the Bilsteins, though I know they have a good reputation--the adjustablity of the Koni's, I feel, is a very strong selling point...and having them made double-adjustable would be even better. How about some Penske's?

I would love to see some springs with a 1.5" drop from the standard Focus ride height with a 200F/245R linear rate. This would be the same F/R ratio as the SVT springs.

Probably too soft for serious auto-x, but it is stiffer than most 1.5" drop springs for those who want a firmer ride without getting into the much firmer 300+ range with the H&R race springs and the too low for practical daily use 2" drop.

This is what I have been trying to find for a while now. A bit firmer without a severe drop. A good compromise for those who have to live with their cars on a daily basis but want to auto-x or track from time to time and find the stock springs, or any other available lowering springs either not quite firm enough or too low.

Ataru,
You've basically seconded my "Replace the unavailable Apex 1.6" drop" that I described above.

Ataru has a very good suggestion, there just isn't a in between spring. If there was a spring set with the drop of the H&R sports and the F/R ratio of the SVT springs (just stiffer, say 200F/245R), I would buy it*. The race springs to me are, just race spring. I live in Austin most of the year and I would break every rim on my car driving on the roads with Race Springs.

*Funds permitting.

Yup, I kinda third the "replace the 1.6 Apex setup". I didn't know it disappeared, that blows. That was the most entertaining, best handling, budget setup I've seen. Damn riceboys ruin everything wanting a Mad Tyte Drop Yo.


I guess it just depends where Ron wants to be positioned. If he wants to make the ultimate hard-core stock form factor springs, go with Rich's suggestion.

If he wants the ultimate streetable setup, do the 200/250 1.5" setup.

Why not do both?
