Re: T3 front swaybar sr20 and JBC crossmember
I have a couple of things to finish first. Once I have it done I will pop by and show you Mike.
If no one from the future comes back to stop you from doing it then how bad of a decision can it really be?

What we found was when you double the length of the arms, you need to increase the torsional strength of bar by roughly 4 times.
To match torsional strength of our 1 1/8" sway bar, the forward mounted sway bar diameter needed to be over 1 3/4".
Drawing from T3's online info, assumptions and my own vehicle measurements (all very non-scientific) my calculations put the T3 bar as being equivalent to a stock position bar with a diameter between 5/8" to 3/4".
I'm hoping this info isn't completely correct. I am in the process of installing the T3 sway bar on my setup due to clearance issues and I hope I'm not creating another issue by losing sway bar strength. Compounding this issue is that I have extended my Futofab lower control arms for added camber and track width which would effectively add more leverage on the bar. Yet another issue I'm experiencing is that the Futofab control arm does not have good provisions for this new sway bar mount due to that lengthening.
I don't think there is a single perfect solution, but those of us mixing and matching parts are definitely messing things up.

It’s correct

Perhaps Duke style strut mounted end links could help improve the T3 bar to a manageable point?

Dam this sucks im in the same boat. I too am using the futofab control arms.jeffball610 wrote: ↑29 Apr 2021 18:11Dave Patten wrote: ↑07 Jan 2021 06:35 With the TC rod to sway bar clearance being an issue on extremely lowered cars, FutoFab looked into making a similar forward mounted sway bar.
