I got if from American Muscle and I know it's not a Whipple or a Kenne Bell but I can't wait to get it. Does anyone know where I can get a strut brace for the M90? I looked and none of the mass supercharge producers have one and google didn't point me in the right direction either. Also does anyone think leaving the 4.10's on there is a bad idea? I figure it will be 6-7psi and I thought about having the installer also put the 3.55's back in since they are also putting in my front and rear steeda sway bars and some front and rear upper/lower control arms.

I love my 4.10's and I think they are the ultimate hotrod gear but with the boost I think I'm gonna with the longer gear. I'm not wealthy but I have some money to throw around being I am a single dude in the Air Force so if I don't like them I'll swap back in with the 4.10's or 3.73's. But I do love the 4.10's in my set up now.

4.10s were too much for the vortech only when I'd force a kick down (auto) around 20-30mph or so. Off the line, power braking it was pretty well tamed surprisingly. Should be a lot of fun in a manual/boosted..

You'll enjoy the performance increase the M90 gives the car, I certainly do! And, if you feel you need a little more, you can get the 2.57 pulley and a custom tune to add another 40 or so rwhp but, it will void the Roush warranty.
Regarding the STB; there is a vendor on Ebay selling the GT500 brace for $30.00 and it is the real deal but, it may interfere with the closing of the hood, some have had issues and others haven't. Do a search, there was a thead addressing this very subject recently. Without rekindling the great STB debate, I don't think they provide any additional structural rigidity; I didn't notice any difference in handling after it was removed.

you could always get stickier tires/smaller rims, build up the suspension and get a light weight driveshaft to make the GT "feel" faster and accelerate quicker.. not a 40whp gain, but you'll retain the warranty as well as enhance the enjoyability of the ride.

wow $500 to install gears... Thats alot! And if the shop is doing the install and raping you on the gears why not ask them for a tune? and get more power than the canned roush tune?
