The T3 roll center correction blocks allow for additional lowering of the front suspension while keeping the roll center in the OEM position. The blocks go between the strut housing and the knuckle, dropping the outer lower control arm pivot point. Between these and the control arm shanks, the front of the car can be lowered over 2.5″ while keeping the roll center location good. The roll center correctors also allow adjustment of the Ackerman angle. Depending on which holes you put the strut bolts in, you can run zero Ackerman which works well for high-angle drifting, and classic Ackerman which is better for street and grip driving. The roll center adjusters also allow for a kicked outboard increased negative camber setting which can be very helpful depending on what lash-up of other parts you are using. Drift cars often have to run a lot of negative camber to keep the tire tread flat at extreme steering angles and these blocks make getting it easy.
We are also using some of T3’s Super Evolved knuckles. The knuckles are also abound with cool features. By using different pills, you can further adjust the Ackerman angle in addition the the adjustment in the roll center adjusters. Another great feature is the adjustable steering ratio. You can use the inner tie rod holes for faster steering and a lot of steering angle for drifting or the OEM position for street driving and grip driving. The outer position is also advisable when using a manual steering rack. Like all of T3 parts, the amount of thought and flexibility of the parts is amazing.
These pills allow for the Ackerman angle adjustment depending on which hole they are placed in.
To go with everything else, we are using T3’s tie rod ends. These have extended shanks that accommodate fine-tuning of the bump steer. They feature spherical bearings and right and left-handed threading for quick on-the-car toe adjustment. The bodies are CNC machined from aircraft aluminum for strength and lightweight. T3’s suspension parts have more thought and more flexibility designed into them than any other AE86 suspension on the market by far. It is like they followed my like-to-have list of features!

Kakkoii!!!
Speaking of electric power steering, why the EPS in many cars, even some performance cars are so numb? Some even feel like there’s excessive friction in the system that further muddy the steering feedback.
Not sure, you don’t have the torsion bar so it’s more direct.
Really is cool that T3 is doing what they’re doing to support a lot of old weird cars. 1st gen RX-7 lover here, which has much of the same design as the AE86, suspension-wise… actually an FB with a lot of T3 parts podiumed in E Production at the SCCA Runoffs a couple weekends ago, which is a nice testament to their stuff.
Does the AE86 do the same thing the FB does with unequal length rear links or did they do a better job there? Also be curious to see, given the opportunity to change things afforded by parts, where you’re choosing to put the instant centers in practice.
It has some different problems like a ton of roll steer and a crazy amount of anti squat so the car hops like basketballs even with the puny 4AG power.
God save us from OEMs with anti geometry.
Let’s hope for some regular updates.
Love the project and the updates! Im subbed on this for sure
