Diameter for TRD Blue and Daizen rear sway bar
I'm currently in process of mixing and matching rear sway bars (TRD&DAIZEN)
Do you know what is the diameter of both TRD & Daizen rear sway bars, or can i run TRD sway bar on Daizen bushings?

The best person to contact is Todd at TM Engineering. He studied a lot of sway bars (including the TRDs) while doing R & D for the Daizens. I think this topic of mixing and matching has come up before and Todd has warned to not do this. In addition to the diameter, the thickness/hollowness of the bar will come into play. Each front and rear were designed to complement each other. The TRDs and Daizens have different goals and mixing them could become an issue.
I'm not saying don't do it but be VERY careful while you test out the driving characteristics of your mix and match configuration.

I think i'm gonna buy a tool so i can measure both sways on my own , well it never hurt to ask, i guess

Back when I was debating purchasing TRD or Daizen, I recall a post with all those measurements. The problem is that most of those threads deteriorated into very long rants/debates and the particular post will be hard to find. But I agree, just buy some cheap calipers (from harbor freight maybe?) and measure it yourself. Good luck and post your results.
PS: I don't see the terrible danger others see in mixing and matching, as long as you test prudently.

Jake, you have 2 sets of sway bars? lol what a baller or do you not have the TRD set yet?
When you do, let us know how big of a difference there is between the two. I have a my Flex set at the stiffest setting right now and the car has very little roll. So hopefully once I add some TRD sways it will get rid of most of it.

If you're trying to determine the 'rate' of the bar, measuring the outside diameter won't tell you everything. If both bars are hollow, the tube thickness may be different causing the stiffness to be different. If the TRD bar is indeed solid, then the rate will be totally different even if the O.D. is the same.
What's wrong with just using the same front & rear of one or the other brand of bar? I've been running the Daizen bars for over two years and have nothing but good things to say about them. The Daizen rear bar is adjustable- when the bars were installed, we set the rear bar in the middle position. I'm actually going to move it to the outside hole (softer) to settle the car down as it wants to rotate the rear mid-turn if the throttle is lifted. This can be exciting in a big 3800 pound car... I can't imageing running the rear bar at full stiff (unless you want to go drifting).
Haven't there been issues with the TRD bar ends cracking and snapping off?

I can't complain on Daizen sway bars, but the rear one don't perform at the level i want and this is a reason why i'm looking for diffrent options.
There is a difference betwen our needs. I might like someting you don't, but the questions is still same: What's diameter both rear sway bars Daizen&TRD?

This is what you were looking for. See post #16 in this thread. I was interested in those measurements because for a while I wanted to swap the Daizen's poly bushings with the softer rubber bushings from the TRD blues. The Daizens noticeably increased bump stiffness, and rubber bushings would've soften them a bit. Found out, however, that those TRD bushings aren't sold separately. Good luck.

I think you helped me alot since the thread i've started was about maesurement of Rear Daizen and TRD sway bars. I appreciate to all of you who pointed risk involved with what i'm going to do, and whoever is intrested in my peronal jurney with mixing&matching sway bars Thing is more than welcome here

Not sure if your questions were answered but I did remember reading that the trd sways would not fit in the daizen sway bushings. I believe the trd is bigger than the daizens.
I wanted to find out about this b/c I already have the daizen bushings and was going to go with the trd sways, but it mentioned that it wouldn't fit and the trds are much stiffer than the daizens.
