I noticed in the MotoIQ article you guys went with the Whiteline subframe bushings.

From their website, the Sikky bushings:

• Raises subframe .4" inches
• Improves roll center and helps anti squat 
• Improves suspension geometry on lowered cars

Do you guy think that would be worth the extra weight and NVH of aluminum?

I plan to use the Whiteline diff bushings.

Thanks!

 

Won't hurt but for real gains you have to modify the subframe. We did it and gained about 2-3 seconds a lap from better exit traction.

Wow! That's impressive.Where can I find some info on the subframe modifications? :-)

We moved the front of the lower control arm down I think it was like 1/2" and and the rear up 1/2". We left rthe upper alone but I would probably move that next time.
