Bump to get Gary's long term impressions of the suspension set up.
Tossing around ideas for my own upgrades in the next year or so, and this is an attractive combo. The next time I get to drive my BOSS will be in Germany, so this set up would be used for the autobahn and twisty road driving, and hopefully some track outtings.

The brake dive and body roll on quick transitions was getting to me now that I'm harnessed into the race seat and not bracing myself before every turn. I went with the 302S suspension with FRPP springs/dampers versus the coilovers to keep it more streetable. Sorry about the poor camera phone pics, but I was more interested in driving it than photographing it tonight

I wrote up my initial reactions in this thread: http://bossmustangsonline.com/boss-3...e-in-route/75/
Next track event is Memorial Day weekend so that will be the real test.

Hi Rich. I have been VERY happy with this setup. It makes the car much smoother and easier to drive on track with so much less body roll and brake dive. With the adjustable dampers, street driving is really not much different than stock if you soften them up. I would definitely recommend them, not to mention the "intangibles" that go along with buying FRPP parts

And that is an awesome story, it's like the badass Detroit version of the line from the fast and the furious about overnighting parts from Japan.
