Techno Toy Tuning - GTX2 Control arm and T/C Rods


Recommended Posts

I am just posting a couple pictures of T3's GTX2 control arm and T/C rod package that I just received.  There were some concerns in two threads Here and Here as well regarding how the T/C rod connects to the arm.

 

In T3's pictures (seen Here), you can see a rod end where the T/C rod connects to the arm and it can pivot about the connection.  As shown in the two photos below, that has now been changed to a solid rod end that has a tight fit between the brackets.

 

I am going to call T3 in the morning and suggest they update the photos, as the posts above as well as the old photos might "scare" away potential customers.

I plan on installing these today.  I picked up some replacement hardware (Grade 8 bolts with sufficient shoulder length) for the T/C-control arm and sway bar end link connections and cut them to length last night.  A point of note is that the hardware is not metric but rather SAE sizes.

 

I think the worse part of the install will be getting everything adjusted correctly.  I should not have an issue with the roll center adjustment as I am running 16x8 wheels; a previous member had issues with his 15-in. wheels.

I had to remove the RCAs for my GTX2s (early revision) to fit with 16" rims (rota grid16x8 et0).  Other option was keeping the RCAs & adding a wheel spacer, I guesstimated 10mm needed minimum for the 16" rim.  I actually have 15" southern ways on my z now without the RCAs  i just can't lower it as much as I wanted to with out being concerned with bump steer.

 

 Had I known this going in I would have just bought the standard T3 control arms. 

 

Hey T3 - you need to put a warning about this on your GTX2 webpage.

What issues exactly?  There are no issues necessarily.  The only "issue" is potential clearance with the bump steer adjustment.  Saying that, you don't run a RCA adjuster with these as they have RCA adjustment built-in.

 

socorob, there is not really an "earlier" version of the GTX2 that I am aware of.  I believe that they are referring to T3's stand-alone control arm replacement that is based on the stock arm.  The difference in the ends is just a refinement in the design that does not address the clearance issue.

 

seattlejester, yes, I installed them yesterday and confirmed the bump steer adjustment this morning.  I will finish the install tonight (but not take it off the jack stands) and post a couple pictures.

Pictures as promised.  I am running 16x8 +10 wheels with a 10mm spacer in the front. I installed the bump steer spacer which helped to raise the lower portion of the "ball joint" spindle by approximately 23 mm (per T3's website).  I have around 25 mm/1-in. of clearance between the bottom of the spindle and my wheel.
