Sure Grip unit feels much better than Eaton TruTrac did..

@72bluNblu what do you disagree with?

Dr Diff is invoking a PhD in his business name...which may be a "doctor" more along the lines of Dr Pepper or the Rug Doctor...but still, I doubt that he has a PhD in business ethics. Was I actually wrong about that?

He is evidentially strongly advising against a product...for which he's also willing to take your $500 in exchange for. :rolleyes:

It doesn't look good.

I don't know the man. I didn't even know it was one guy before this thread. My comments were mostly meant to be silly...but also made out of my own frustration since I just invested in one of these units on the basis of trusting the reputation of a product and trusting the word of a competing vendor who stands behind their work.

I do believe @jbc426 about his observations and it makes me wonder if I'll have to deal with this after pouring in a lot of time, money and work into the Dart this winter.


I have yet to get the car up to the high speed required to verify the original vibration issue has been eliminated. That being said, the car just feels better while accelerating out of the hole with the Suregrip as opposed to the TrueTrac. It just feels more solidly driven by both rear wheels.

I still have my fingers crossed and I generally try to keep it under 100mph around here, but I will update once I gather the high speed data.
