I have the Circuit Sport FSTB and the GT-Spec 6pt brace, and i've tracked the G numerous times.
IMHO, the FSTB hardly makes a noticeable difference. The 6pt does. It works fairly well through the limits, but is a bit harsh in daily Houston driving. I actually take it off for DD. BlackBetty has all of them now, i believe, and he seems fairly happy with them.
Here's my old review of the 6pt, along with a bit more info on how the rivets work (for those unfamiliar.)
6pt. Chassis Brace Installed - Thoughts - G35Driver
And here's a short description from Mark at GTSpec on the various braces:
1. Rear M Shape Brace + Rear 2 Point Tie Brace
This will be the first 2 brace to get. These two braces tie the lateral arm and control arm together. These two braces act almost like a sway bar. We have tested the same braces on 350Z and the most effective brace so far.
2. Rear 6 point subframe brace
Because it's a bit pricey, that's why I list this brace as #2. If budget allow, this brace is a great addition. The brace link the rear subframe to the chassis. It added three extra reinforcement points per side. It's a 5 piece kit thus a higher price than rest of the braces.
3. Fender Brace
Fender brace ties the front engine compartment to your mid chassis. Known to be used on many track car, it provided extra reinforcement for the front of your car.
4. Front subframe tie brace 2/4 point.
I list this lower than the rest mainly because the front subframe are already very stiff. These two braces reinforce the existing mounting points. It still provide added reinforcement but not as much advantage compare to the rest of the braces.
5. Front subframe left + right tie brace
This brace is the last on the list because it's a significantly smaller brace compare to the rest. However, it does added two extra reinforcement points to the front subframe, but compare to the rest of the braces that's available, this brace has less effect.
Everyone will ask "how much" more advantage do you have compare to stock. It's really hard to measure and give you an exact number. I believe there are no set standard on how to measure it.
You really have to try it and feel how much more these brace will help the total driving experience. We can guarantee that you will come back for more once you have tried them
