Thank you! We should have our coil-overs ready by the end of January, they will be used with our pro-action adjustable shocks and struts. Plus we will be coming out with some new exciting spring set ups early next year. Plus, a new system to correct front roll center.
:cheers:

We will have up to date findings tomorrow to share with the performance handling S550 enthusiast. Plus, a complete suspension build list which is affordable.

Waiting on the suspension build as well as the future hybrid springs. :)

Hi Everyone,
Our first event went well. We will be updating this list as we move forward. Again, this is for the S550 enthusiast to follow along with our findings.

Things that need to be done before next event:

1. New tires, we were on one year old Hoosiers
2. Need more front camber and rear roll stiffness
3. Oil temp was sky rocketing after 4 laps, need to reposition Oil cooler and run even a bigger cooler.
4. The P/P Radiator worked great for now, once we start producing more power may need to be changed.
5. Change from 355 TO 373 gears, our Diff cooler worked fantastic!!
6. By early spring we will install a new powertrain with a built Coyote engine and Tremec Trans

That's it for now.

Thanks for the update on parts... missing one pretty important suspension part though. I take it the springs are the prototype springs not currently available?

Will you be answering questions people ask in this thread? or just posting your content? Not trying to be rude just want to know how to handle this. I'd like info on the brake ducts and tow hooks please if its the former.

Thank you for reaching out. Steeda will answer your questions. I reached out to engineering last night should have your request shortly.

Thank you for your patience.

Brake ducts not available yet, still under development.

Tow Hooks Ford racing M-1759-A

Keep you posted on the brake ducts as we move forward.

Coil Over spring rates, these are not final. Our Pro-Action dampers on the 3/4 to firm setting is comparable to the GT350R dyno graph

250lb front linear rate
275lb rear dual rate prototype to match GT350R spring rate.

Ah yeah. That is interesting that you all went 3/4 on the Pro-Action for the track, still means you have a little bit more to squeeze out of it :D

I'm curious how this will work on the street. 250lbs in the front seems like a big jump but I'm wondering what a full soft or just above full soft will yield on the street.

Can you release the range of the dual rates for your rear springs? I'm not familiar with the GT350R spring rates.

Great work on these. I'm really interested to see how these turn out.

TBD
For reference, Swift Spec R springs have a 270 front spring rate. I'm not entirely sure if there is a significant difference between the Mustang's strut assembly and your typical front coilover assembly in terms of the affect of any given spring rate, but numerous people quite like those springs and have no complaints about them on the street.

Much appreciated!

Thanks!

To clarify, I'm looking for the solution for the tow hook mounting, not the hook itself.

Brake ducts will be very popular if you release a quality kit, which I have no doubt you will!

Are those wheel rates? Because the reported rear spring rate for the GT350/R is 914 lb/in. And wouldn't you want a higher spring rate on a real race car than the GT350R street car?
