Protoform mazdaspeed6 lightweight is the most common go-to shell for carpet. Other shells can work well too, in certain conditions, depending on driving style and setup, but speed6 lw is what most people use, the majority of the time.
Just answering because it's pretty late in England, so Skiddins might not see your question until tomorrow and I kind of doubt he'll have a vastly different response than this anyway.

I've tried other bodies that seem pretty good and usually get the same laptimes, but they are simply more difficult to drive.
I always run light weight shells
The only other bodies I've liked on carpet was the Nazda 3 (may need to make the setup a little easier to drive first) and Blitz TSX (on higher grip carpet) but my main choice is the Speed 6 LW just like everyone else

I was just wondering what would be a good FDR for a 7.5t mod motor for a track with a 100ft straightaway? I am new to brushless mod motors.

+1, I would go with recommended FDR aroung 6 to 6.5. Pull off and check motor temps every few minutes and move from there based on track requirments. For comparison, I gear a 5.5T at 8.1 FDR and add/subtract boost if needed. Hope this is helpful.

I run a 4.5t Boosted. Gearing is 26/110 for a 8.04. Coming off in the 120's after 6-8 minutes.

We have two asphalt tracks in my area that I've been racing at this summer. One is always meticulously prepped and sprayed with a mix of grape soda and snow cone syrup, resulting in great traction. The other track is often not prepped at all, which leaves it dusty with very low traction.
My setup works great on the high grip track. I'm basically running the kit asphalt setup but with longest camber links, 2* toe in the back, RSD progressive asphalt springs (green front, silver back: http://www.reflex-sd.com/RSD-20mm-As...ir_p_1735.html), 1* camber all around and 5.5mm ride height. Droop is 2mm in the front and 2.5mm in the back. Kit sway bars.
That setup does not work very well on the low traction track at all. The car pushes into the corner and fishtails out of the corner if I'm not super gentle on the throttle. Basically crap. I know I have to soften the car up, but my question is this: should I be softening up the springs or the sway bars first? Or both?
Thanks!

Yes, but 4.5t doesn't need as much boost as slower motors and a 7.5 is a much slower motor. Back in the 17.5 boosted days I think most guys were 6-6.5 FDR with a ton of boost. My 10.5 car I run 7.5 fdr with way more boost than my 4.5t can take. If I gear it higher, say 6.5 fdr it's slower and hotter no matter what boost settings I use.

maybe i am missing something here but anyone using current limiting to assist in heat management?, granted different tracks may get more or less advantage out of this, but it definitely helped me,.. i run 4.5t boosted geared around 6.5 to 7.0 depending on tyre size ( foam lola class ) on medium /large outdoor asphalt
